Revision 0.1 5 ChannelMaster Truck Package (PS18 & HPA/UHPA) Field Repair Nucomm products are designed with easy access to components to facilitate service. When troubleshooting, the user is cautioned to read all module descriptions in this manual. Some Nucomm modules cannot be serviced in the field. Warnings are included in the circuit descriptions and on certain modules themselves, however the lack of a warning cannot be construed as a statement of safety. To prevent voiding of the Nucomm warranty that protects the equipment, please contact Nucomm before servicing or making any repairs. Replacement Module Troubleshooting to the component level is often not cost-effective and frequently impossible. Often the practical method of effecting field repairs is to substitute known good spare modules for suspect units. Nucomm maintains an inventory of replacement modules for its standard line of products. Equipment Returns Do not return any Nucomm product to the factory until you have received a return materials authorization (RMA) number and shipping instructions from Nucomm. When returning equipment to Nucomm, please encolse a letter containing the following: • RMA number. • Model number. • Serial number. • Frequency operating range (in case of modules). • A detailed description of the problem. • Name of engineer or technician we may contact in regards to this problem. • Include a “ship to” and “bill to” address. Ship ALL RETURNS to: Nucomm, Inc. Attn: RMA 101 Bilby Road Hackettstown, New Jersey 07840 International Returns In the case of units being shipped from outside the United States, Nucomm recommends the use of a courier such as Federal Express, UPS, etc., and that the goods be shipped DOOR-TO-DOOR PRE-PAID. This will eliminate Customs costs, handling charges and delays. Enclose all the information above, plus a statement that the equipment was manufactured in the United States (the latter is needed to expedite customs processing).
Revision 0.1 ChannelMaster Truck Package (PS18 & HPA/UHPA) 6 Unit Identification Given the model number, the unit configuration can be determined using the following: AAAAA – CMTP– BB Power Output Model Generalized Frequency Band Designator Where: AAAAA = mean frequency band center in GHz rounded to the closest GHz. This number is then multiplied by 10. For multiple bands, each center frequency designation is separated by a backslash "/". BB = Used to identify the power output, per the following Power Output Designators: Power Output is represented by Letters (A-Z; A=1, B=2, C=3, etc) for the analog power, and Numbers (0-9) for the digital power. For example, a 5W Analog / 2W digital system would be described with a power indicator of "E2". A Dual-Band system would have two sets of power indicators, to show the power levels at both bands.

Revision 0.1 7 ChannelMaster Truck Package (PS18 & HPA/UHPA) 1.0 DESCRIPTION & FEATURES Nucomm’s optional TruckMount Package (aka “Truck Package”) for the ChannelMaster TX1 provides ENG/OB truck operators the flexibility to use the ChannelMaster TX1 as a full-featured truck transmitter, while retaining the ability to easily remove the transmitter for portable use as required. The TruckMount Package can be configured for Single or Dual-Band operation, and includes High Power Mast Mounted Amplifier(s) (HPA’s) to increase the range of the base ChannelMaster transmitter. The Block Diagrams in Figure 1-1 and Figure 1-2 show the available Single and Dual Band configurations. The Single Band TruckMount Package consists of a 2RU* “nested docking station” style Control Drawer which accepts the ChannelMaster portable, and a Mast-Mounted HPA which is typically attached to the side of the Pan & Tilt, at the top of a telescoping mast, with a Nucomm mounting plate. The Control Drawer and Mast-mounted HPA are interconnected via SF-214 RF that is typically installed in a NYCOIL assembly for carriage up the mast. The Dual Band TruckMount Package consists of a 2RU* “nested docking station” style Control Drawer which accepts the ChannelMaster portable, and two Mast-Mounted HPA’s which are typically attached to the sides of the Pan & Tilt, at the top of a telescoping mast, with Nucomm mounting plates. The Control Drawer and Mast-mounted HPA’s are interconnected via a single SF-214 RF that is typically installed in a NYCOIL assembly for carriage up the mast. In the case of the Dual Band system, the cable from the Control Drawer is first attached to the 7 or 13GHz amplifier, and then routed over to the 2 GHz amplifier. *Note: Depending on the RF power output level of the ChannelMaster portable transmitter, the overall height of the docked transmitter and Control Drawer may exceed 2RU due to the heat sink fins integrated into the top of the ChannelMaster portable. All signals required at the amplifier (RF, Control and Power) are diplexed onto the SF214. The standard AC power supply for the TruckMount Package Control Drawer has an operating range from 90 to 240 VAC (40 to 60Hz). Optionally, a +11 to +32 VDC power supply, or a Universal Power Supply can be factory installed. The Universal Power Supply operates on 90 to 240 VAC (40 to 60Hz), or +11 to +32 VDC.

Revision 0.1 23 ChannelMaster Truck Package (PS18 & HPA/UHPA) 4.0 OPERATION 4.1. Control Drawer Front Panel The Control Drawer Front Panel controls the selections related to the use of the 2GHz or 7GHz High Power Amplifiers, as well as selecting various antenna parameters. (Refer to Figure 4-1.) The controls are divided into three sections: • Control Unit - for selecting the Power Amplifier band. • Antenna - for selecting the type of antenna as well as directional antenna polarization. • Power - for selecting the amplifier operation mode as well as overall unit mode. Figure 4-1: Control Drawer Front Panel
Revision 0.1 ChannelMaster Truck Package (PS18 & HPA/UHPA) 24 4.2. Control Unit Section The Control Unit section serves two purposes: the selection of which power amplifier is to be used, and the monitoring of RF output power. The selection of amplifier is accomplished by pressing the “Band” Button. The “Band” Button toggles the unit between enabling the 2GHz Amplifier and the 7GHz Amplifier. This feature will still work even if the unit is placed into Bypass Mode. For monitoring RF output power, a bar indicator is located just above the “Band” Button. As the output power increases, so will the length of the bar indicator. However, there is no direct number representation. 4.3. Antenna Section The upper most rotary switch in the Antenna Section, allows the operator to choose the type of antenna to be used. The operator can choose between either “Omni” or “Directional”. If “Directional” is chosen, the operator then must set the lower most rotary switch for the type of polarization to be used with the antenna. There are four options: • CW - Clockwise • CCW - Counter-Clockwise • V - Vertical • H - Horizontal 4.4. Power Section The Power Section allows the operator to select the unit’s mode of operation. For choosing the unit’s mode of operation, the lower rotary switch can select one of three conditions: • OFF - The entire Control Unit is powered-off. • BYPASS - The Mast Mounted Power Amplifier is powered down, while the RF signal from the ChannelMaster is sent directly to the antenna via the Power Amp Bypass Relays. Bypass Mode is used to further reduce the RF Power Level sent to the Antenna. • ON - Allows the chosen power amplifier (refer to “Band” Button) to amplify the RF output signal being applied to the Antenna. If “ON” is chosen as the unit’s mode of operation, the amplifier mode of operation must then be selected. This is accomplished by pressing the upper toggle button until the desired amplifier mode is decided upon. There are three options: • HI - places the Mast Mounted Power Amplifier in high power operation. • LOW - places the Mast Mounted Power Amplifier in low power operation. • STBY - places the Channel Transmitter in Standby Mode.
