Installation of Optional Interface Cable Assembly 60201136
Interface Cable Assembly 60201136
Optional Ritron cable assembly 60201136 (6-Conductor Cable, Loudmouth
®
Interface) is used to connect the Loudmouth
®
relay
switch to an optional strobe light, or any other device where a simple switch closure is desired. The cable assembly also
provides input for the Switch Input closure.
The 60201136 cable assembly includes:
6-conductor cable with a mating connector to the Loudmouth
®
for easy installation.
Heyco strain relief used to retain the 6-conductor cable to the Loudmouth
®
case
and provide a weather seal.
The 6-conductor cable assembly connections provide:
Black
Ground connection for 10.5VDC
Red
10.5VDC (400mA MAX) output used to power an external device such as a
strobe light
Blue
Relay Switch Output provides a normally-open switch that closes whenever a
valid message is received. The relay switch output can be configured as a
normally-closed switch that opens whenever a valid message is received (see
Relay Polarity Jumper at right)
Green
Relay Switch Output second switch connection used with Blue wire
White
Switch Input connection will cause the Loudmouth
®
to play a pre-recorded
“Switch On” message when pulled to ground (closed) and “Switch Off” message
when released from ground
Brown Switch Input ground connection
Interface Cable Assembly 60201136 Installation
1. Loosen the 4 screws in the front
corners of the case. These screws
are retained to the housing with
rubber O-rings, DO NOT remove the
screws from the housing.
2. Separate the case front from the case
back.
3. Disconnect the RPS-1B power supply
and BP-LM-Li22 backup battery
connected to the radio.
5. Install the Heyco strain relief
included with cable assembly
60201136. Do not tighten the
sealing nut at this time.
4. Remove the plug from the case
bottom to expose the ½” hole used
for the Heyco strain relief.
6. Pull cable assembly 60201136
through the strain relief from the
inside as shown. Plug the cable
assembly into the pcb connector
and tighten the sealing nut.
