DIGITAL UPGRADE NOTES The DXDPRO-10U is suitable for upgrading analog transmitters to digital service. Special attention must be given to every detail of the conversion to insure that the desired objective is met and that it is compliant with FCC requirements. The equipment used to make a conversion is expensive and can be costly. The following needs to be considered when making a conversion to digital from analog; 1. Replace the modulator with a good quality digital modulator with adaptive linear and non-linear correction 2. Check the drive level required to achieve the desired output power level from the transmitter. A driver may be required after the modulator 3. The output band pass filter will have to be replaced with a MASK FILTER. Consider using a mask filter that is rated at 1.25 times the desired output power level. 4. Digital transmitters and mask filters need to be correctable by the modulator. This will require the addition of dual directional couplers before and after the mask filter to provide correction signals. 5. IMPORTANT: Modification of FCC approved equipment requires special test and test equipment. A qualified Broadcast engineer should be employed to do this work. D. 48 VDC OPERATIONS The DXDPRO-10U modulator is designed to be used with an external 48 VDC supply similar to those found at telecom sites. If the Modulator is used with standard AC supplied power sources the DC backup can be automatically switched with internal circuits. The battery charge level can be monitored on the front panel or on the web page. The operating range is from 42 to 52 VDC. E. GPS RECEIVER ACTIVATION The DXDPRO-10U has a built in GPS receiver.

ETHERNET WEB PAGE CONTROL AND MONITORING DXDPRO-10U MODULATOR MANUAL THE INFORMATION PROVIDED HEREIN IS PINEAPPLE TECHNOLOGY INCORPORATED PROPRIETARY INFORMATION AND CANNOT BE COPIED OR DISTRIBUTED WITHOUT PRIOR AUTHORIZATION 28 V.5 DXDPRO-10U ETHERNET WEB PAGE CONTROL AND MONITORING (Continued) B. ETHERNET WEB PAGE SETUP General Introduction The web service control interface allows monitoring of status as well as configuration of the operational parameters of the device subject to the log-in status for the user (observer, operator or administrator). The user interface (web browser display) applies a user friendly concept where the general navigation between individual sub menus is based on a block oriented representation of the controlled device. The specific control for a certain function is therefore easily accessed by ‗dragging‘ the functional block of interest into the configuration section of the display. The web service interface is equally useful for controlling the PT2000 Terrestrial Gateway product in a configuration with a direct connection (Ethernet patch cable) between the PT2000 Terrestrial Gateway product and the PC as well as in the typical operational environment where multiple products are accessible from the PC across a shared network. Document structure and scope This instruction manual is divided into three main sections:  Electrical interface and IP address configuration;  Operation principle for the Web service interface; and,  Software update over Ethernet. The present document describes the operation from a generic viewpoint and it does therefore not address in detail functions or settings applicable to a specific member of the Terrestrial Gateway product family. C. IP ADDRESS CONFIGURATI0N IP address settings for the PT2000 Terrestrial Gateway product can be carried out in several different ways: a) Hardware preset to default status b) Configuration over Ethernet (the current address setting must be known and that the PC used for the configuration must be configured with a compatible address) 1. IP Address Preset  IP address : 192.168.168.168  Network Mask: 255.255.0.0

IP ADDRESS CONFIGURATI0N (Continued) 2. IP Configuration Over Ethernet (Terminal) The PT2000 Terrestrial Gateway product can be configured for either static or dynamic IP address operation. The factory default setting for the unit is:  Address management: DHCP = OFF (static IP address)  Default IP: 192.168.168.168  Default Mask: 255.255.0.0  Default gateway: 192.168.1.1 Provided that the current IP setting for the unit is known (IP address and network mask) it is possible to carry out further query of IP settings by connecting a PC to the Ethernet port. (The PC must, of course, be configured with IP settings that are compatible with the address space currently set for the PT2000 Terrestrial Gateway product). 3. IP configuration over Ethernet (Web Service) The factory default setting for the unit is:  Address management: DHCP = OFF (static IP address)  Default IP: 192.168.168.168  Default Mask: 255.255.0.0  Default gateway: 192.168.1.1 Provided that the current IP setting for the unit is known (IP address and network mask), it is possible to carry out further query of IP settings by connecting a PC to one of the three RJ45 management ports of the PT2000 Terrestrial Gateway product (the PC must of course be configured with IP settings that are compatible with the address space currently set for the PT2000).

DXDPRO-10U ETHERNET WEB PAGE CONTROL AND MONITORING (Continued) D. WEB SERVICE OPERATION The PT2000 Terrestrial Gateway product is fully controllable over ethernet by means of the web service function (web browser control). The PT2000 web service is designed for use with Internet Explorer V7 and Mozilla Firefox V2 so it is strongly recommended to use one of these two browser types for the operation. The PT2000 Terrestrail Gateway unit must be configured in advance for the same address space as the PC used for the control and the PC must be connected to one of the TCP/IP mangement eithere directly or over a network. Preparation Of The Web Browser The status pages provided by the PT2000 web service are updated in the web server whenever the operational status of the device changes. However, changes to operational status, occurrence of alarm messages, etc, may be masked if the web browser is configured for use of locally cached web pages. To ensure that the web browser always displays the latest status from the PT2000 web service and not displays outdated cached information it must be configured specifically to check for newer versions of a web page on every visit to the page. For Microsoft Internet Explorer 7 this is done as follows: a) Select ‗Internet options‘ from the ‗Tools‘ menu. b) Select ‗Browsing history‘  ‗Settings‘ from the ‗‘General‘ tab page. c) Make sure ‗Every time I visit the page‘ is ticked. 1. Login To The Web Service Connection to the web service function is established simply by entering in the Web browsers address field the IP address assigned to the specific PT2000 Terrestrial Gateway unit. A login window will appear in order to authenticate the user‘s access to the web service.

Web Service Main Page Connection to the web service function is established simply by entering in the Web browsers address field the IP address of the PT2000 Terrestrial Gateway unit. As soon as the connection has been opened the primary control and status page will appear. The page is divided into an upper section and a lower section. The upper section provides a graphic representation of the block schematic of the device. The block schematic provides general status information about the device and serves as navigation tool for accessing specific status and configuration menus. The lower section provides space for simultaneous display of three control and status panels for specific functional areas of the unit. The control panels are easily adapted to the current activity by dragging-and-dropping the required functional block from the upper section of the screen to the lower section of the screen (See next page - Section D.- Web Service Operation –- Part 3 - Control Panel Configuration for details). In case an alarm condition exists for one of the functional elements shown in the upper section of the screen, the particular element will be shown in red color. Functional elements that are in the normal operational status will be shown in green color. Functional blocks that are not used in the current configuration are shown in grey color.

Web Service - Operation Principle Control panel configuration The control panel (lower section of the screen) is easily adapted to the current activity by dragging-and-dropping the required functional block from the upper section of the screen to the lower section of the screen. Control panels for three functional blocks can be open simultaneously in the lower section. The ‗Functional Blocks‘ in the upper section of the screen can be subdivided into three types:  Main function block: a main function block holds the top level control and status parameters for a specific function. These blocks are identified by the blue label ‗attached‘ above the block (white text on blue background). In the below example screen print main functional blocks exist for the sub-functions Reception, Input, Mode, Pre-Correction, Output and Reference.  Specific function block: a specific function block holds control and status functions for a specific function within a ‗Main functional block‘. In the below example screen print it can for example be noted that the Reception main block contains specific functional blocks for the tuner and the channel filter functions. Likewise, it can be seen that the mode block contains specific functional blocks for the HP Coder, LP Coder, OFDM and SFN functions.

ADAPTIVE PRE-CORRECTOR WEB SERVICE OPERATION DXDPRO-10U MODULATOR MANUAL THE INFORMATION PROVIDED HEREIN IS PINEAPPLE TECHNOLOGY INCORPORATED PROPRIETARY INFORMATION AND CANNOT BE COPIED OR DISTRIBUTED WITHOUT PRIOR AUTHORIZATION 43 V.6. DXDPRO-10U ADAPTIVE PRE-CORRECTOR WEB SERVICE OPERATION A. INTRODUCTION This section describes the web browser based operation of the Adaptive pre-corrector for the PT2000 Terrestrial Gateway unit. For an introduction to IP address configuration, log-in procedure and general operation principle for the web service1 control interface for the DXDPRO product family please refer to the separate publication DXDPRO Modulator and Repeater Products Web service Interface Instruction Manual available from Pineapple Technology, Inc.. The web service control interface allows monitoring of status as well as configuration of the operational parameters of the adaptive pre-corrector device subject to the log-in status for the user (observer, operator or administrator). The user interface (web browser display) applies a user friendly concept where the general navigation between individual sub menus is based on a block oriented representation of the controlled device. The specific control for a certain function is therefore easily accessed by ‗dragging‘ the functional block of interest into the configuration section of the display. The web service interface is equally useful for controlling any of the PT2000 Terrestrial Gateway products in a configuration with a direct connection (Ethernet patch cable) between the PT2000 Terrestrial Gateway unit and the PC as well as in the typical operational environment where multiple products are accessible from the PC across a shared network. SECTION STRUCTURE AND SCOPE This section is divided into three main chapters: a. Electrical interface for the adaptive pre-corrector b. Operation principle for adaptive pre-corrector c. Application of the adaptive pre-corrector in combination with Echo Canceller option . B. ELECTRICAL INTERFACE 1. General information The adaptive pre-corrector‘s electrical interface consists of two SMA type coaxial connectors:  Sense input 1: Non-linear sense port  Sense input 2: Linear sense port

ELECTRICAL INTERFACE 2. Interface to the Transmitter The non-linear sense input must be connected to a suitable coupler/tap-off at a point right after the power amplifier before any band limiting filter. The linear sense input must be connected to a suitable coupler/tap-off point after the channel filter. Notice further that the bandwidth between the RF output of PT2160 and the input of the power amplifier must be at least 20MHz wide to ensure effective non-linear pre-correction of the amplifiers non-linearity. PTPT C. OPERATION OF ADAPTIVE PRE-CORRECTOR 1. Connection and Verification of Signal Levels The RF output and the sense inputs of the PT2000 Terrestrial Gateway unit must be connected as described in above in Sub-section 2 - Interface to the Transmitter. The graphical illustration of the two sense inputs in the web service block schematic will appear in green color if the level is within the valid range for the respective input. If the level is marginal relative to the required max/min limits the input will be shown in yellow color. If the level is outside the valid range the input is shown in red color. For optimal result the corrector should only be operated with input levels in the ‗green‘ state. Performance with ‗yellow‘ input state is not guaranteed. The adaptive pre-corrector is not usable when the level is in the ‗red‘ state. PT2160 Power Amplifier Channel Filter RF out Sense-1 Non-Linear Sense-2 Linear

OPERATION OF ADAPTIVE PRE-CORRECTOR 2. Preparation of Web Service Interface To enable web service control of the non-linear and linear adaptive pre-corrector, proceed as follows: a) Drag the linear pre-corrector block to the configuration panel b) Drag the non linear pre-corrector block to the configuration panel c) Drag the adaptive pre-corrector block to the configuration panel (this panel provides status info only and it is therefore as such not strictly required for operation of the adaptive system) d) Drag the three control blocks into the configuration panel one-by-one: Depending on the current operational mode for the pre-corrector system the linear and non-linear blocks may appear in grey or in green. When the pre-corrector function is disabled the respective block (linear and/or non-linear) is shown in grey. When the pre-corrector function is enabled the respective block (linear and/or non-linear) is shown in green color. When the active pre-corrector mode is ‗adaptive‘ a green arrow will connect the adaptive function block and the respective pre-corrector block. When the adaptive pre-corrector mode is ‗static‘ (manual correction mode) the connection between the adaptive function block and the respective pre-corrector block is grayed out.

OPERATION OF ADAPTIVE PRE-CORRECTOR 2. Preparation of Web Service Interface (Continued) 3. Linear Pre-Corrector Configuration Linear Pre-Corrector Mode Selection The linear pre-corrector system can operate in three different modes. The required mode is selected by opening the operational mode ‗drop-down‘ list (I). The available modes are:  Monitoring: No pre-correction is applied to the RF output (the corrector characteristic is neutral). The amplitude ripple and the group delay performance is measured and displayed provided that a valid feedback is applied to the RF sense input 2.  Static: The currently loaded manual linear pre-corrector characteristic is applied to the RF output. The manual pre-corrector characteristics must be generated and uploaded by means of the PC software package IMD Buster McTwo. The curve format used by the manual pre-corrector system is incompatible with the curves used and generated by the adaptive system.  Adaptive: The current adaptive linear pre-corrector characteristic is applied and maintained according to the adaptive pre-corrector mode selected (see below for details).

OPERATION OF ADAPTIVE PRE-CORRECTOR 3. LINEAR PRE-CORRECTOR CONFIGURATION Adaptive Linear Pre-Corrector Mode Selection The adaptive linear corrector can operate in four different modes. The required mode is selected by opening the operational mode ‗drop-down‘ list (II). The available modes are:  Idle: The current adaptive pre-corrector characteristic is applied to the RF output. The pre-corrector algorithm is stopped. Changes in transmitter characteristic will not be tracked by the pre-corrector.  Continuous: The instantaneous adaptive pre-corrector characteristic is applied to the RF output. The pre-corrector algorithm runs continuously.  Run to target: The instantaneous adaptive pre-corrector characteristic is applied to the RF output. The pre-corrector algorithm will run until the set threshold value is obtained for the upper respectively the lower RE spectrum shoulder.  Auto run: The instantaneous adaptive pre-corrector characteristic is applied to the RF output. The pre-corrector algorithm will run until the set threshold value is obtained for the upper respectively the lower RE spectrum shoulder. The adaptive pre-corrector algorithm will be automatically restarted in case the upper and/or lower shoulder performance subsequently drops below the set threshold. Adaptive Linear Pre-Corrector Threshold Settings The threshold values for the adaptive pre-corrector system‘s ‗Run to target‘ and ‗Auto run’ modes are accessed and set by expanding the ‗Auto-run and run-to-target threshold settings‘ control (III). Notice that the respective parameter values must be ‗enabled‘ by ticking the associated enable field in order for the parameter to have any effect on the pre-corrector algorithm. II

There is a choice of two possible reset functions:  Neutral: The linear adaptive pre-corrector is instantly set to neutral characteristic when this control is operated. It is recommended to start the first adaptive alignment of a new amplifier from the neutral state.  Factory: This reset function is intended for future use. The idea is that the transmitter manufacturer is allowed to save an adaptively derived curve characteristic and later retrieve this specific characteristic by activating the ‗factory‘ reset. III IV

The adaptive pre-corrector algorithm will be automatically restarted in case the upper and/or lower shoulder performance subsequently drops below the set threshold. Adaptive Non-Linear Pre-Corrector Threshold Settings The threshold values for the adaptive non-linear pre-corrector system‘s ‗Run to target‘ and ‗Auto run’ modes are accessed and set by expanding the ‗Auto-run and run-to-target threshold settings‘ control (III). Notice that the respective parameter values must be ‗enabled‘ by ticking the associated enable field in order for the parameter to have any effect on the pre-corrector algorithm. Adaptive Non-Linear Pre-Corrector Reset Functions The adaptive non- linear pre-corrector control panel includes two controls for resetting the corrector characteristic (IV). There is a choice of two possible reset functions:  Neutral: The non-linear adaptive pre-corrector is instantly set to neutral characteristic when this control is operated. It is recommended to start the first adaptive alignment of a new amplifier from the neutral state.  Factory: This reset function is intended for future use. The idea is that the transmitter manufacturer is allowed to save an adaptively derived curve characteristic and later retrieve this specific characteristic by activating the ‗factory‘ reset. III IV

OPERATION OF ADAPTIVE PRE-CORRECTOR 5. ADAPTIVE PRE-CORRECTOR STATISTICS The ‗Adaptive‘ pre-corrector block provides various statistics concerning the adaptive process when dragged to and expanded in the lower half of the web service page.  Elapsed time, Current iteration: Displays the time elapsed for the ongoing iteration (data collection and analysis) for the adaptive process. The elapsed time may accumulate continuously in the event that the sense input is invalidated and thereby preventing successful data collection and analysis.  Last turn-around time: Displays the recorded time consumption for the last completed iteration (data collection/analysis/curve implementation). The iteration time may typically vary from less than 10 seconds up to about one minute depending on the signal characteristic and the type of adaptive correction running. The shortest iteration time is noted when only the non-linear adaptive pre-corrector is running. The iteration time is increased when the adaptive linear pre-corrector process is running.  Linear clean run: Accumulated count of the number of times the adaptive system has discarded the collected linear data set and initiated a new collection of data. Under normal conditions this counter is ‗0‘.  Linear bad sense count: Accumulated count of the number of times the data collection from the linear sense port has failed for reasons other than level out of range (typically due to application of an invalid type of spectrum on the sense port). Under normal conditions this counter is ‗0‘.  Non-Linear clean run: Accumulated count of the number of times the adaptive system has discarded the collected non-linear data set and initiated a new collection of data. Under normal conditions this counter is ‗0‘.  Non-Linear bad sense count: Accumulated count of the number of times the data collection from the non-linear sense port has failed for reasons other than level out of range (typically due to application of an invalid type of spectrum on the sense port). Under normal conditions this counter is ‗0‘.

ECHO CANCELLING AND ADAPTIVE PRE-CORRCTION NOTE: THIS FEATURE IS NOT INCLUDED IN THE DXDPRO LINE PRODUCTS. THIS IS AVAILABLE AND THE CUSTOMER SHOULD REQUEST A QUOTATION FOR PRICE AND AVAILABILITY. The adaptive pre-corrector option works very well in combination with the echo canceller option by ISO-channel repeater mode with the DTXPRO-800U digital repeater unit from Pineapple Technology, Inc. However, the echo canceller‘s ability to work effectively with high positive loop gains is dependent on already completed linearization of the amplifier non-linearity by the adaptive pre-corrector system. Therefore, when setting in operation a system that involves the adaptive pre-corrector as well as the echo canceller in an ISO-channel scenario it is recommended to follow one of the following two methods: Off-Line Linearization The ISO-channel repeater should initially be put in operation in a configuration where feedback between output and input is non-existent. This can be done either by feeding: a) The input with the actual RF feed off-air while feeding the power output from the ISO-repeater into a dummy load instead of feeding it to the transmitting antenna or b) A locally generated RF feed into the unit from a test transmitter which is not affected by the output of the ISO-channel repeater. In this configuration the adaptive non-linear pre-corrector should be run until a shoulder performance of about 40dB or better is obtained from the power amplifier. After this initial linearization of the power amplifier the ISO-repeater can be put in operation with ‗live‘ input and output. Gradual Loop Gain Ramp-Up The ISO-channel repeater may alternatively be put in operation by starting at a low ‗max loop gain‘ setting for the echo canceller (for example 0dB or lower) and for each step allowing the adaptive non-linear pre-corrector to maximize the power amplifier performance to a shoulder level of about 40dB or better before increasing the permitted loop gain by a few dB.

APPENDIX-A CLIPPER OPERATION 1. GENERAL INFORMATION The clipper function included with the Terrestrial Gateway product allows a controlled limitation of the output signals peak-to-average-power-ratio (PAPR). When the clipper is disabled the output from the Terrestrial Gateway product will exhibit a PAPR equivalent to the inherent PAPR for the modulation format when the unit is configured/operated as a modulator. When the unit is configured as repeater or transposer the PAPR of the processed signal may be limited by headroom constraints in equipment prior to the repeater or transposer input. In the latter scenario the PAPR measured on the RF output may therefore be lower than the inherent PAPR for the modulation format in question even when the clipper is off. Although the highest power peaks for multicarrier COFDM formats like DVB-T and MediaFLO reach a level about 15dB over the signals average RMS power the high peaks have limited energy content. The peaks are therefore not of immediate danger to the safe operation of a power amplifier following the modulator output even in the normal case where the average power setting for the amplifier is not backed off with the full PAPR relative to the peak power rating for the amplifier. The highest peaks are simply clipped by the power amplifier. However, a performance improvement and an extension of amplifier lifetime may be obtained if the peaks are limited to a point just below the amplifiers clip point by the clipper function of the Terrestrial Gateway product. When the clipping is done by the Terrestrial Gateway the following characteristics are obtained: a) The potential short time effect on the amplifier characteristic after a power peak is eliminated; the clipping in the Terrestrial Gateway is an instant process with no subsequent effect on the signal processing characteristic. b) The unavoidable noise that results from the clipping may, when the clipping takes place in the DXDPRO modulator, be distributed as preferred by use of the ‗soft clipper‘ function (see below). When the clipping occurs in the amplifier the noise resulting from the clipping will be distributed evenly below, within and above the used channel. When using the clipper function of the Terrestrial Gateway the noise may be displaced from the upper and lower sideband of the channel to minimize disturbance of adjacent channels. c) By clipping the signal in the Terrestrial Gateway product any possible degradation of amplifier life time by repeated peak power stress is minimized. 2. OPERATION OF THE CLIPPER FUNCTION Level Definition The point of clipping relative to average power level for the signal processed can be set by dragging the clipper block to the configuration panel. The Clipper level control can be set in the range from 12dB to 2dB. This setting refers to the baseband processing which is equivalent to a range from 15dB to 5dB for the actual RF output (the addition to the signal of a single CW carrier, the local oscillator used in the up-conversion process, corresponds to an increase of the PAPR by 3dB).

APPENDIX-A CLIPPER OPERATION 3. OPERATION OF THE CLIPPER FUNCTION For practical reason the clipper function is considered ‗active‘ whenever the clip point is set to a value lower than 12dB irrespective of the actual PAPR format for the modulation standard in use. When set to the ‗active‘ state the clipper is shown in green color in the block schematic. When the clipper is inactive it is shown in grey. Clipper in the inactive ‘off’ state (12dB): Clipper active (PAPR setting 8dB):

APPENDIX-A CLIPPER OPERATION 3. OPERATION OF THE CLIPPER FUNCTION Identification of Optimal Clipper Setting The optimal clipper setting can be identified by monitoring the output of the power amplifier using a spectrum analyzer. The steps are as follows: a) Ensure that the clipper initially is set to 12dB b) Ensure that the clip filter is initially set to 0%. c) Configure the spectrum analyzer for zero-span operation with the view focused on either the upper or lower shoulder of the signal. A resolution of 0.1dB to 0.5dB per division is recommended. Maintaining the original level in the form of a second trace on the analyzer (clear-write  View) is recommended for easy identification of change in the shoulder level. d) Now, gradually increase the level of clipping applied by the Terrestrial Gateway product (1211,51110,510……..etc). When an increase of the shoulder level observed on the spectrum analyzer is just noticed it shows that the clipping applied by the Terrestrial Gateway is now limiting the peaks to a point fractionally below the clip point of the amplifier itself. Although the point will be individual from amplifier to amplifier and dependent on the actual average power level and peak power rating of the amplifier the point is typically found around of a clipper setting between 8 to 6 dB. Selection of Clipper Softness (Clip Filter) The clip filter setting may be varied according to preferences between 0% and 100%. The 100% setting provides for maximum suppression of the clipper noise from the sidebands (lower and upper adjacent channel) while the tradeoff is a reduction of the in-band MER performance.

PINEAPPLE TECHNOLOGY, INC VII. DTXPRO-800U INSTALLATION PROCEDURES DTXPRO-800U OPERATING AND SERVICE MANUAL THE INFORMATION PROVIDED HEREIN IS PINEAPPLE TECHNOLOGY INCORPORATED PROPRIETARY INFORMATION AND CANNOT BE COPIED OR DISTRIBUTED WITHOUT PRIOR AUTHORIZATION 68 VII. DTXPRO-800U INSTALLATION PROCEDURES To ensure long and reliable trouble-free service from the DTXPRO-800U transmitter the following steps for installation are recommended: 1. MECHANICAL INSTALLATION: The DTXPRO-800U was designed to be installed in a building protected from the weather. The building should have a hard-surface floor such as concrete with a moisture barrier. This barrier could be pressure-treated wood sub flooring which could be anchored to the concrete and to the transmitter to make the installation earthquake resistant. Allow a minimum of three feet around the transmitter cabinet for service access.. Provisions for air inlet and exhaust from the room must allow air flow with minimal obstruction. In the event that the room temperature exceeds 35º Celsius (95º F), cooling air must be provided so that the room temperature will not exceed 35o Celsius under worst-case conditions. Notice: This equipment is HEAVY and must be handled by professional movers with proper equipment. Any damage caused by the installers is not covered under warranty. Check to ensure the installing crews have proper insurance coverage. 2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for safety and operational reasons. The single point grounding technique can be effective to protect multiple pieces of equipment installed inside an equipment rack cabinet. Treat the rack the same as you would a building, a copper bus bar has been mounted inside the cabinet to act as both an entrance panel and reference ground for all conductors entering and leaving the rack. It is recommended the customer install an AC surge protector at this point in shunt to ground, and install a series impedance between the panel and the equipment. The chassis of each piece of equipment has been bonded to this buss bar with a single copper braid or strap. Redundant ground connections by means of the AC cable and the shields of audio cables should be avoided when possible. Finally, connect the rack‘s access panel to the building reference ground using a heavy gauge wire such as #2 AWG stranded copper or solid copper buss one (1) inch wide by 1/8 inch thick for connections. The bonding between the transmitter and the ground rods must be good quality and protected from corrosion. The ground wires should run over the floor and be connected to the ground rods located outside the building. The wire should not go thru the concrete floor but over and around it. 3. AC WIRING: AC voltage for the transmitter is normally 110 VAC. Connections to the AC Main should be made as follows: --- RED and BLACK wires are connected to the 110 VAC. --- A WHITE wire is connected to NEUTRAL. ---A GREEN wire is connected to SAFETY GROUND. NOTICE: All wiring of this type must be done by a QUALIFIED ELECTRICIAN and must conform to LOCAL and NATIONAL wiring codes. Consult with your electrician to ensure that the proper breaker size is selected for the main circuit.

DTXPRO-800U INSTALLATION PROCEDURES (Continued) 4. ANTENNA CONNECTION: The transmitter is equipped with a type N connector located at the rear of the rack. The RF ATSC compliant mask filter and output directional coupler(s) are provided with the transmitter and are to be located and mounted at the customer discretion. Pineapple Technology recommends the filter be securely mounted above the transmitter cabinet but not in a position that could inhibit air circulation from the top of the cabinet. The directional coupler is usually mounted on the output of the mask filter convenient for connection to the station antenna transmission line. Two cables have been provided for connection between the output directional coupler monitor ports and the DXDPRO-10U modulator. Conditions vary from site to site so some engineering may be required to ensure that the antenna is receiving the correct amount of power to comply with FCC licenses and to ensure safety from lightning, etc.

DTXPEO-800U SERVICE REQUIRMENTS DTXPRO-800U OPERATING AND SERVICE MANUAL THE INFORMATION PROVIDED HEREIN IS PINEAPPLE TECHNOLOGY INCORPORATED PROPRIETARY INFORMATION AND CANNOT BE COPIED OR DISTRIBUTED WITHOUT PRIOR AUTHORIZATION 71 VIII. DTXPRO-800U SERVICE REQUIREMENTS Routine maintenance of the DTXPRO-800U consists of cleaning or replacing the air inlet filter. In normal operating environments this should be done once a month or more often in dusty environments. Cleaning should be done with a light detergent. Rinse and dry the filter carefully before installing. Any detergent residue could damage components in the modulator. For this reason, the first option should be to replace the filter with a new one (PTI Part Number 990202) The following data should be recorded in the station log. This information should be compared to previous test recordings to insure normal operations. 1. DC SUPPLY VOLTAGE 2. DC CURRENT 3. OUTPUT POWER PERCENT (%) 4. REFLECTED POWER PERCENT (%) 5. HEAT SINK TEMPERATURE IN DEGREES CELCIUS Under normal operating conditions is the performance of the adaptive linear and non-linear correction performance should be checked. This can be done remotely if the unit is connected via Ethernet or on each visit to the site. Adaptive linear correction is normally placed in the idle mode once the correction is complete. If so, the corrector can be placed in AUTO RUN for a while to optimize the correction and then returned to the idle mode.
