Section 1 Introduction Overview The ZR310 is a community repeater panel (Figure 1-1) which provides individualized repeater service for up to 70 customers or customer groups on a single RF channel. It acts an interface between a GM300 transmit radio, and a GM300 receive radio, providing TPL and DPL encode/decode, repeat audio processing, and all timer functions. An internal database holds the various attributes associated with each user group. Nearly all of the ZR310s functions can be customized for each of the 50 TPL tones and 20 DPL codes. You can program all of the functions of the ZR310 in three ways: • Rem otel y, using DTMF over the radio channel • Locally, with the Motorola RIB compatible interface for connection to a computer • By using a touch-tone telephone Standard Features The following is a list of ZR310 Community Repeater Panel features. • Decoding / Encoding for 50 TPL tones and 20 DPL codes. • Remote control and programming via DTMF radio, or DTMF from a telephone plugged into the programming jack. • Remote enable / disable of all user groups. • Per-user programming. • Cross-tone, cross-code, tone-code encoding. • Privacy made prevents barge-ins. • Vacant tones and codes can be reserved. • Courtesy tone. • Automatic station ID per user. • Accessory PTT input with selectable TPL / DPL encode. • Repeater set-up / knockdown remote DTMF commands. System Configuration Unlike a conventional community repeater panel. which usually consists of a system card (or equivalent circuitry) and up to 70 different plug-in tone cards, the ZR310 incorporates one card that allows system and user programming. System Functions System programming replaces the system card in a conventional community repeater panel. The system function controlled by the ZR310 software are listed below: • System Access Code • Repeater Set-up / Knockdown • Time-out Timer • Courtesy Tones Frequency • Anti-Kerchunker Filter • Station ID • Speed, Timer, Frequency • Program Mode Access Code • Accessor y PTT TPL / DPL Encode • Carrier Repeat ID March, 1993 6880902Z68-O Section 1-1
Section 1 Introduction User Functions In the ZR310, assigned user numbers are the equivalent to the 70 plug-in tone cards contained in a conventional community repeater panel. The following steps describe the process the ZR310 uses to find user information. 1. The ZR310 detects a code or tone. 2. The code / tone is decoded to a user number. 3. The user number points to the area in the database containing information about that particular user. Re to Table 3-1 for code / tone to number conversion. The user functions controlled by the ZR310 software are listed below: • User Enable • TPL or DPL Encode • Reserve Mode • TX Hang Time • Morse ID Call Sign • Courtesy Tone • Co-Channel Protect Selection • Privacy Mode Physical Description The ZR310 is a self-contained repeater interface component designed to fit into the top shelf of the GR300 Repeater Station. The front panel (Figure 1-1) contains • Audio adjustment • TPL / Set-up adjustment • LED indicators. to display the status of the various functions • Programming jack, used for DTMF telephone programming or local programming with an IBM PC via an RIB programming interface • Interconnections to the transmit and receive radios are made via the 16-pin Transmit and Receive connectors located in the rear of the panel.

Section 2 Installation Overview This section explains how to install the ZR310 community Repeater Panel into the GR300 and complete the cable connections that wer e started in the Installation section of the GE300 Maintenance Manual. If you require access to the indicators, jumpers, or other components, refer to the Maintenance section for disassembly procedures. Equipment Required For Installation The following equipment is required for installation: • a communications service monitor and ONE of the following • a hand-held or mobile radio with DTMF encode capability • a DTMF telephone • a PC capable of running the Motorola radio service software (RSS) • an ANSI terminal communications program Installation Procedures If you have followed the installation procedures found in the Installation section of the GR300 main manual, the GR300 is assembled. Now you need only to install the ZR310, finish the required cable connections, reinstall the fan assembly, and perform the required tests and adjustments. To identify the parts and their corresponding call outs, refer to Figure. Assembly Perform the following steps to install the ZR310 into the GR300 housing and to complete cable connections. The RF and repeater cables should already be connected to the radios, if you installed them according to the Installation section of the GR300 Maintenance Manual. Install the ZR310 Into the GM300 1. STOP! Before going any further, did you make sure that the jumpers inside the GM300 transmit and receive radios were set to the correct positions? (Refer to table 2-2.) 2. Place the ZR310 on the top shelf of the GR300 repeater housing, allowing the rear panel to be partially exposed. 3. Connect the receive radio repeater connector to the ZR310 Receive connector (Figure 2-1). 4. Connect the transmit radio repeater cable to the ZR310 Transmit connector. 5. Position the ZR310 so that its mounting screw holes are aligned with the corresponding mounting holes on the repeater housing 6. Using a T25 Trox screwdriver, secure the ZR310 to the repeater housing using two M5x0.8x8 machine screws (7). 7. One end of the equipment power cable has only one connector. Connect it to the top connector on the power supply (Figure 2-2). 8. The other end of the equipment power cable has two connectors. Connect one of these connectors to the receive radio and the other to the transmit radio. 9. Connect the lower frequency radio to the LOW port on the rear of the duplexer. (Figure 2-3). 10. Connect the higher frequency radio to the HIGH port on the rear of the duplexer. (Figure 2-3). 11. Thread the grounding nut onto the grounding lug. CAUTION To avoid damage to cable tabs and radio components, install cables with locking tabs up March, 1993 6880902Z68-O Section 2-1
