SETTING UP THE PDL HIGH POWER BASE Overview of PDL High Power Base (PDL HPB) Radio Modem Front Panel Digital DisplayTX IndicatorRX IndicatorChannel Change PushbuttonAMP POWERIndicatorON / OFF IndicatorON / OFF PushbuttonFigure 1 - PDL High Power Base Front Panel Buttons The ON/OFF button is used to turn the PDL HPB station on and off. Turn the unit on by pressing the ON/OFF button and holding it until the channel display indicator is lit. Turn off the PDL HPB by pressing the ON/OFF button until the display goes blank. There is a one-second turn-off delay in the power button to prevent inadvertent turn off.
6 Setting Up the PDL High Power Base The CHANNEL button is used to display and change the channel. Press the CHANNEL button momentarily to display the selected channel. To change the channel, press the CHANNEL button once to light the display, and then again to change the channel. Use the CHANNEL button to select the “b” setting. With “b” selected, the PDL HPB will be placed in AutoBase mode. This mode selects the channel for transmission automatically. Display The seven-segment numeric display is used to indicate the channel or mode selection. To conserve power, the display is only lit for a short time following the pressing of the CHANNEL or ON/OFF buttons. Channel selections range from Channel 0 to Channel 15. Two digit channel numbers are displayed by alternately flashing a 1 followed by the second digit. The seven-segment display also has a decimal point to the lower right of the number. The decimal point is lit to indicate that the channel selection was done automatically with AutoRover or AutoBase. Indicator LEDs The power LED has two purposes – first, to indicate that the unit is powered, and second, to indicate the level of charge for the power supply. The power LED will blink to indicate that the base station battery is at or below 10 Volts and may require charging.
PDL User's Guide 7 The amplifier power LED indicates the RF power output level selected. When lit, the amplifier power LED indicates that the RF output power is set to high. When blank, the amplifier power LED indicates that the RF output power is set to low. The TX LED indicates that the PDL HPB is actively transmitting. In most RTK applications, the base station TX LED will blink once per second. The RX LED indicates that the PDL HPB is receiving an RF carrier signal. If the RX LED is lit for extended periods of time, or continuously, then another radio station is operating on the same frequency. This competing RF source may interfere with the GPS RTK system, and may require that you change channels for better performance. Rear Panel Data Connector A five-pin circular LEMO style receptacle accepts both programming and GPS model specific cables. The supplied cables are labeled “RADIO” on the end that plugs into the base. Align the red dot on the plug with the red dot on the receptacle and push until a clicking sound is heard. To remove the cable, grasp the blue cable over-mold, and retract the locking mechanism by pulling the knurled barrel of the plug toward your palm.

PDL User's Guide 13 Battery Care Base station kit shipments to North America include a 33 AHr deep-discharge gel lead acid battery. This battery provides all day operation with ample power for both the PDL and the GPS RTK reference station. International Shipments For shipments outside of North America, we include battery bag, power cables with fuse, and hardware for a user supplied battery. Select a deep discharge battery of the type designed for golf cart or wheel chair operation, and that has a capacity of 33 AHr or greater. Batteries designed for automotive use will be damaged by the repetitive discharge/charge cycles and should be avoided. Charging The supplied charger provides two-stage charging and should be connected to the battery following every full day of operation to assure good battery life and performance. The first stage quickly charges the battery to capacity and the second stage trickle charges the battery to maintain a full charge. If the battery is maintained in storage for an extended length of time, it is important to periodically charge the battery as extended time in a discharged state may damage the battery.

26 Setting Up the PDL Rover Configuring the GPS Rover See the GPS receiver model addendum that is included with this manual for specific instructions on configuring your GPS rover for optimal performance with the PDL. Detailed instructions are also available on our web site at www.pacificcrest.com. PDL Rover Default Settings Refer to Table 1 in Setting Up the PDL Base for the default factory settings of your PDL Rover. Priority Power Selection Power may be supplied externally to the PDL Rover if supported by the connected GPS receiver. If power is available from the GPS, the PDL Rover will first use the internal battery power until depleted, and then switch to external GPS supplied power. As the internal power is depleted to a level indicating that the internal battery should be charged, the power LED begins blinking at once-per-second. When the battery is depleted to a very low level, the external power will be selected and the power LED will "blip" a short flash at once-per-second. Battery Care The PDL Rover has an internal power supply that allows all-day operation without taking power from the GPS. The light-weight Lithium-Ion single cell battery can be recharged more than 1000 times, providing 3+ years of normal use. We recommend daily charging for best battery life and performance.
PDL User's Guide 27 9 Warning: The internal Lithium-Ion battery is NOT USER SERVICEABLE. Do not attempt to open the enclosure or replace the battery. Lithium-Ion batteries can be dangerous if mishandled. The PDL Rover has a built-in charger that monitors and controls the charging of the internal battery. The internal battery quickly charges in less than 4 hours, and can be charged with the supplied charger, or from an external 12 volt supply. We recommend charging the internal battery at room temperature. Charging is inhibited if the ambient temperature is below 0° C or above 40° C. 9 Warning: The internal battery must not be subject to operating temperatures below -20° C. Subjecting the battery to conditions below -20° C will produce permanent battery damage, and is not covered by the warranty.
TIPS AND TECHNIQUES FOR BEST PERFORMANCE Antenna Antenna placement is critical for good performance. Range and coverage is directly proportional to the height of the transmitting and receiving antennas. Where possible, select a reference station location that takes advantage of terrain to get the transmitting antenna as high as possible. Always use the telescoping antenna mast, and raise the antenna as high as is practical and safe, given terrain and wind conditions. Power Supplies Maintain batteries in a fully charged state. Both the PDL Base and internal PDL Rover batteries will live longer if not allowed to become completely discharged. We recommend routinely connecting both the base and rover PDLs to their chargers on a nightly basis. This will assure optimal performance and long battery life. How to Use AutoRover™ AutoRover is a feature that allows the PDL Rover to automatically synchronize to the PDL Base. Enable this feature by pressing the CHANNEL button until an "r" is displayed. After selecting "r", you will note that the display will flash each programmed channel for approximately 3 seconds, until a base station broadcast is encountered. The PDL Rover will continue to scan until a broadcast is found.
PDL User's Guide 29 The next time you turn on your unit, you will see an "r" momentarily, after which the scan process will begin. To manually select a channel for operation, press the CHANNEL button until the desired channel is displayed. With AutoRover the PDL Rover scans each programmed operating frequency, looking for a signal from the PDL Base. When a signal is found, the PDL Rover selects that channel for operation. 9 Caution: Multiple PDL Base stations operating in a single area may lead to the PDL Rover selecting the wrong base. In such circumstances, we recommend manually selecting the channel. How to Use AutoBase™ AutoBase is a feature that allows the PDL Base to automatically select a channel based on a channel selection algorithm. These features can be selectively turned off to allow you to manually select the channel of operation on both the PDL Base and Rover. To enable AutoBase, press the CHANNEL button on the PDL Base until a "b" is displayed. After selecting "b", you will note that the display will flash each programmed channel for approximately 1 minute, during which time the channel is analyzed for background noise and co-channel interference. After cycling through all channels, the PDL Base will select the channel that appears to provide the clearest channel access.
30 Tips and Techniques for Best Performance Following channel selection, the data received from the GPS will automatically begin transmitting. 9 Warning: Depending on the number of channels programmed, channel selection can take from 1 to 16 minutes. We recommend that you set up and turn on your PDL Base station as soon as possible during system setup to prevent delays. Equipment Care Routine equipment care will prolong the life and reliability of your PDL family products. Radio communication equipment is susceptible to damage from shock or environmental extremes. Never operate the PDL equipment out of the operating specifications contained in Appendix B. Error Codes The PDL performs a variety of power-up and run-time tests to assure optimal operation. Tests include environmental as well as electrical measurements designed to avoid damage to the unit while maintaining adequate operation. In the event of an error condition, a 3-digit error code is flashed on the display. Error codes begin with an "E" followed by two numeric digits indicating the failure mode. Table 2 lists the possible error conditions.

FCC RULES AND REGULATIONS Licensing Requirements It is the responsibility of the PDL Base station owner to comply with applicable rules and regulations concerning the operation of a radio transmitter. In the United States, the FCC regulates the licensing of this equipment. Application for a license is made by submitting FCC form 600 along with evidence of frequency coordination (if required) and applicable fees. Similar licensing requirements exist worldwide. Penalties for broadcasting without a license can be severe, and may include the confiscation of your radio and GPS equipment. For more information, contact our customer service department. 9 Warning: Always obey local licensing requirements and restrictions. Equipment Compliances PDL products have been tested and found to comply with Parts 15 and 90 of Title 47 of the Code of Federal Regulations. The PDL products have also been tested and found compliant for type certification and approval in many other countries worldwide. For more information concerning our worldwide compliances, contact our customer service department.
34 FCC Rules and Regulations Being Part of the RF community Operation of a licensed radio product makes you a member of the RF community. Be aware that virtually all frequencies licensed are provided on a shared basis with other users. Each frequency used in RTK GPS activities has certain restrictions and limitations. For complete information, refer to Part 90, Title 47, of the Code of Federal Regulations. Most frequencies sharing data transmissions and voice transmissions give priority to voice users. Be mindful of the persistent nature of a GPS RTK data transmission and always limit your RF transmission output power when performing close-in survey situations to avoid interference with co-channel users. We recommend using the low RF power setting for construction site and other line-of-site surveys with baselines less than 2 miles (depending on terrain). 9 Warning: If you are in conflict with a co-channel user, select another frequency to avoid formal FCC actions. In most cases you are required to vacate a frequency upon complaint by a shared channel voice user. Most survey operations are itinerant in that the system is moved on a frequent basis. For fixed system installations, you should not use frequencies set aside for itinerant operations, but should coordinate a frequency based on the fixed area operation. Regulations differ from country to country, so please be aware of the local regulations prior to using the PDL equipment.
PDL User's Guide 35 Automatic Station Identification For operation in the United States, the FCC requires that radio transmitters used for GPS RTK applications periodically broadcast a station identifier. The station identifier is the call sign assigned to you on the station license. The PDL supports the broadcast of station identification in a manner that meets the requirements of the FCC. Upon receipt of equipment, program your FCC callsign into the configuration of your PDL using PDLCONF software. This is only required for transmitters. 9 Warning: Failure to transmit your station identification is in violation of FCC regulations. Use PDLCONF software to enter your FCC callsign. Carrier Sense Multiple Access (CSMA) CSMA is a technology implemented in the PDL Base to meet FCC transmitter requirements. CSMA holds off the radio transmission if the frequency is currently being used by a co-channel user. On occasion, you may note that the radio broadcasts stop for short periods of time. Most often, this is a case of co-channel interference and the PDL Base is holding off broadcasts due to the FCC mandated CSMA. GPS RTK equipment is designed to function with intermittent gaps in the data. Heavy co-channel use may limit the ability of the PDL Base to transmit the required information. In areas of heavy co-channel usage, try changing channels to a less used frequency.

APPENDIX A - SAFETY INFORMATION Exposure to Radio Frequency Energy The PDL radio modem products are designed to comply with the following national and international standards and guidelines regarding exposure of human beings to radio frequency electromagnetic energy: • FCC Report and Order FCC 96-326 (August, 1996) • American National Standards Institute (C95.3-1992) • National Council on Radiation Protection and Measurement (NCRP - 1986) • International Commission on Non-ionizing Radiation Protection (ICNRP - 1986) • European Committee for Electrotechnical Standardization (CENELEC) To assure optimal radio performance and to ensure that exposure to RF energy is within the guidelines in the above standards, the following operating procedures should be observed: • DO NOT operate a transceiver when someone is within the distance noted below of the antenna (unity gain). • For the frequency range 450-470 MHz 3 m (approx. 108 inches) for PDLHPB 0.5-35 Watt 1.5 m (approx. 54 inches) for PDLLPB 0.5-5 Watt • And for the frequency range 150-173 MHz 7 m (approx. 252 inches) for PDLHPB 0.5-35 Watt 3 m (approx. 108 inches) for PDLLPB 0.5-5 Watt
42 Warranty If using an antenna with a gain greater than unity please calculate the RF exposure as per the formula given below: Distance = √ [gain of antenna x power output x 300] √ [2 pi x frequency] Power output in Watts, frequency is in MHz, distance in meters, and antenna gain is absolute value. • DO NOT operate the transceiver unless all RF connectors are secure and any open connectors are properly terminated. • DO NOT operate the transceiver with a damaged antenna. If a damaged antenna comes in contact with the skin, a minor burn may result. • DO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere. 9 Warning: Changes or modifications not expressly approved by the FCC could void the user’s authority to operate the equipment.
