    MM-007024-001 LOCATING COMPONENTS Plan the mounting locations of all components (radio, control head, antenna, and cables) and determine the routes for all wiring and cables. Particularly consider the connection of the control head for planning purposes. • Determine the customer’s preferences, if any, for location of components. Comply with these preferences as long as they are consistent with safety recommendations and guidelines presented in this manual, and other generally accepted professional radio installation practices.

  • Page 21: Mounting The Mobile Radio In The Trunk

    MM-007024-001 MOUNTING THE MOBILE RADIO IN THE TRUNK This section provides details on mounting the mobile radio in the trunk of the vehicle. See Figure 5-1 and refer to the respective wiring diagram at the end of this manual as necessary. See section 9 (page 33) for control head installation procedures.
  • Page 22 MM-007024-001 radio installation and removal ease. A minimum distance of two (2) inches is recommended from the front edge of the bracket. The bracket is front/back symmetrical, and left/right symmetrical. As all installations differ, bracket-to-vehicle mounting screws are not included. Steel #10 self-threading screws are recommended.

  • Page 23: Mount The Radio Into The Bracket

    MM-007024-001 2. Deburr all newly drilled mounting holes. 3. Set the bracket in place, and install and tighten the mounting screws. 4. Verify the bracket is firmly secured to the mounting surface. A secure mount prevents unreasonable vibration, which could damage the radio and/or cause its cable connections to loosen. MOUNT THE RADIO INTO THE BRACKET The radio should now be mounted into the bracket according to this procedure: 1.

  • Page 24: Antenna Installation

    MM-007024-001 ANTENNA INSTALLATION ANTENNA MOUNTING LOCATIONS At this time, review all information presented in the SAFETY INFORMATION section of this manual (begins on page 5). A transmitting antenna must be installed in accordance with the guidelines presented in the SAFETY INFORMATION section. Use Table 1-1 as a guide for determining the best possible mounting configuration/location in order to reduce human exposure to radio frequency (RF) WARNING...

    RF safety. The antenna cable of M/A-COM approved antennas should never be cut to a shorter length. Instead, excess cable must be tied and stowed. This not only prevents the antenna from radiating above its intended or configured power, but it also allows for future installation considerations.

  • Page 26: Install And Connect Gps Antenna

    1. Once the mounting location is selected, refer to the antenna manufacturer’s mounting and testing instructions for installation guidance. If necessary, contact M/A-COM’s Technical Assistance Center (see page 13 for contact information). 2. Route the cable from the GPS antenna to the rear of the radio. The cable should be kept out of casual contact from persons within the vehicle.

    MM-007024-001 RADIO DC POWER INSTALLATION Refer to the wiring diagrams at the end of this manual. The diagram in section 19 (page 61) includes mobile radio with the CH-103 Control Head. The diagram in section 20 (page 63) is nearly the same with the exception of the three cables designed for use with the CH-103PA Control Heads.

    MM-007024-001 relay could be completely bypassed in this configuration. Similarly, the 2-ampere ATM fuse and fuse holder included in the fuse kit are not needed. Because the “hot wired” configuration renders the function of the Time Delay Relay useless, the Control Head will draw substantial quiescent current continuously from the battery when turned off.
  • Page 29 MM-007024-001 3. Connect the ring terminal directly to the battery’s positive post (or if present, to a stud on the battery’s main/non-switched power distribution terminal block). 4. Mount the Time-Delay Relay firmly onto a flat surface within the vehicle’s engine compartment and near the battery but away from sources of excessive heat.

Label and route the DC Power Cable’s white wire to the vehicle’s fuse box. Tie and stow as necessary so the wire remains out of the way of casual contact and wire chafe is avoided. The Control Head wakes up the radio via the CAN port when power is applied.

    MM-007024-001 BRACKET INSTALLATION When drilling holes, be careful to avoid damaging some vital part of the vehicle (fuel tank, transmission housing, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. After drilling pilot holes, CAUTION remove all metal shavings from them (deburr) before installing mounting screws.

  • Page 37: Install Fuse Holder And Dc Power Cable And Make Power Connection

    MM-007024-001 9.5.1 Install Fuse Holder and DC Power Cable and Make Power Connection The Control Head has a moderately high quiescent-current drain so red wire power connection to the output/load side of the Time-Delay Relay (relay’s yellow wire) through the Fuse Block is highly recommended.
  • Page 38 MM-007024-001 below. The Control Head’s DC Power Cable and associated fuse and wire terminal devices are shown in Figure 9-4. Only the Control Head’s white wire and the Time-Delay Relay’s white wire must be connected to the ignition or switched power sense. When this vehicle line is asserted (i.e., power switched on), the Control Head automatically powers-up the radio via the CAN NOTE connection.
  • Page 39 MM-007024-001 2. Route the white wire of the Control Head’s DC Power Cable from the back of the head to an area near the switched ignition power source. At the back of the head, be sure to maintain a cable service loop of at least six (6) inches.
  • Page 40 MM-007024-001 9.5.3.2 Control Head and Radio Turn On with a Manual Switch With this wiring configuration, the Control Head and radio are manually turned on and off via an on/off switch mounted separately from the Control Head and radio, not through the vehicle’s ignition switch/key.
  • Page 41 MM-007024-001 Head will still draw substantial current to eventually discharge the battery over a reasonably short period of time. In this configuration, the Control Head’s white wire is simply grounded to the vehicle’s chassis. The ATM fuse and fuse holder included in the fuse kit are not required in the “hot wired” configuration. 1.

  • Page 42: Data-Only Radio Connections

    MM-007024-001 10 DATA-ONLY RADIO CONNECTIONS The Data-Only configuration of the radio has no Control Head. The only difference in connections from an installation with a Control Head is with respect to ignition sense wiring. For a Data-Only radio, follow the procedure described in either section 9.5.3.1 or 9.5.3.2, except where the white wire of the Control Head’s DC Power Cable is referenced, make the connections with the white wire of the radio’s DC Power Cable instead.

    MM-007024-001 11 MICROPHONE INSTALLATION 11.1 CH-103 AND CH-103PA CONNECTIONS There are several versions of microphones available for use with the radio. In all cases, there is a 14-pin connection to the front panel of the Control Head. 1. Plug the microphone’s 14-pin connector to the Control Head’s microphone connector as follows: Align the white arrows on the mating connectors, then push the cable’s connector into the mate—the outer ring of the connector will rotate during the insertion.

It breaks out into three (3) separate D-subminiature 9-pin (DB-9) type connectors. It also has blunt-end wires (i.e., not stripped or terminated with a connector) for optional/miscellaneous connections. This combination allows straightforward access to all external I/O connections provided by the radio.
