Compatibility
Zetron Model 38 Repeater Panel is compatible for all versions of SLR 5000 Series Repeater software
and hardware.
Hardware Connections
The connections between the SLR 5000 Series Repeater and the community repeater panel are
facilitated with a multi-conductor cable connected between the SLR 5000 back panel AUX 25-Pin
connector and that of the community repeater panel. The connection provides the following signals:
• Transmit Audio
• Receiver Audio
• Push-to-talk (PTT)
• Carrier Operated Relay (COR)
• 13.6 VDC nominal (See note)
• Ground
NOTICE: If this connection is used, the external equipment must draw less than 1 A.
Signal connections are noted in Figure 83: CPS Settings to Configure SLR 5000 Series Repeater for
Analog Mode on page 141. The SLR 5000 Series connector and physical Pin locations are noted in the
backplane interface board section of this manual. See Zetron Model 38 Repeater Panel manual for its
connector and physical Pin locations. The part number for a pre-fabricated cable is noted in the SLR
5000 Series ordering guide.
