FAST ACCESS SYSTEM TRUNKING • The MRS 904T is a stand-alone, 400 mW, 900 MHz Trunking Repeater that supports the LTR signalling format . Fast Access System Trunking (FAST) is the latest advance in trunking system technology from Uniden. The FAST System delivers almost instantaneous transmission of voice communications as well as data, without the slow response and frequent busy signals associated with older trunking systems. A FAST System may have up to 20 individual channels.

INSTALLATION The MRS 904T is available in a desk top or a slide rack mount version . You can place the deskmount version on any flat surface , such as a desk or a table. You can place the slide rack mount version in an ARX 430 cabinet (see figure 2) or an ARX 440 rack (see figure 3) . / / • :n '- Co ci C\J 1:'? I/ 16" _1 l:= j ~9. 75" 19" -- 21 .75" Figure 2. ARX 430 Cabinet ,.,, 1 able 1.
Figure 5 shows a recommended ten channel layout using ARX 440 racks. The lefthand and righthand racks contain ten repeaters . Each repeater consists of an MRS 904 repeater, an ARX 780 telephone interconnect, an ARX 31 0 power supply, and an ARX 1600 power amplifier. The middle rack contains equipment that is used by all of the repeaters.
REPEATER NETWORK DATA LINK (RNDL) BUS The Repeater Network Data Link (RNDL) bus connects the repeaters in the trunking system to each other and to the ARX 820 Validator or ARX 850 Air Time Billing option. Each end of the RNDL should contain a 100 ohm pull-up resistor. The 100 ohm pull-up resistor is built into the ARX 820 and the ARX 850. Therefore, if use an ARX 820 or ARX 850 , place it at one end of the RNDL bus .
9. Install tne cable from the ARX 310 power supply in the "DC INPUT" receptacle. 10. Repeat this procedure for each MRS 904 in the trunking system.

OPERATION ~ OPERATING CONTROLS AND INDICATORS All of the operating controls and indicators, except the power switch, are located on the front panel (see figures 8 and 9). Power Switch - The power switch is located on the rear panel. This switch turns the MRS 904 repeater on or off. POWER Light- The POWER light glows steadily when the 13.6 VDC primary power is applied to the MRS 904 radio through the DC INPUT connector. This light flashes on and off when the backup 12.
RNDL Connector - Connects the repeater to the Repeater Network Data Link (RNDL) Bus. See page 63 for recommended RNDL Bus connection MIC Jack: The MIC (Microphone) jack connects the ARX 100A microphone to the MRS 904 repeater. TX Jack- The TX (Transmitter) jack is aType N Connector (400 mW) that connects the transmitter of the MRS 904 repeater to the antenna. RX Jack- The RX (Receiver) jack is a Type N Connector that connects the antenna to the receiver of the MRS 904 repeater.
BASIC THEORY OF REPEATER TRUNKING Repeater trunking was designed to permit multiple users to equally and automatically share all channels. If a repeater is busy and the system has two or more repeaters, the incoming signal may be "handed off" to another repeater. This provides more rapid communication than with single repeater systems, where each call must be completed before another can be handled.
