Installation - Monroe Electronics R194 Instruction Manual

Installation

1. Mount the R194(s) into the rack. If only one R194 is used, the Master/Slave
switch on the rear panel MUST be set to Master.
If multiple R194's are installed in series ONLY THE FIRST ONE should
have the Master/Slave switch on the rear panel set to Master. All other
units MUST be set to Slave.
2. Connect your first audio/video source and output to the channel 1
connections. (2 conductor shielded cabling is recommended for all audio
connections.) Continue connecting the rest of your audio/video sources and
outputs to the remaining channels of the first R194 and remaining one.
3. Connect the Relay 1 connections from the R189 One-Net to the Trig
connection on the R194. If you are using more than one R194, connect the
Trig connections in parallel between all of the R194's used.
4. Connect the L+ and L- out audio connections from the R189 to the L+ and
L- connections of the EAS Audio in connector of the R194. For stereo
audio, you must also connect R+ and R- out connections from the R189 to
the R+ and R- connections of EAS Audio in connector of the R194.
5. If more than one R194 is to be used, connect the L+ and L- connections
from the EAS Audio out connector on the first R194 to the L+ and L-
connections of the EAS Audio in connector on the second R194 in the
chain. If the right channel audio was used in the previous step, that output
must be connected to the input in the same way.
6. If the units are daisy-chained, the video for each unit MUST be installed on
INPUT ONE before any other inputs can be used.
7. Connect the 12-volt DC output of the AC adapters to the 12V connections of
each of the R194's used. (WH to +, shield to GND) Note: It is good practice
to plug the AC adapters into a battery backed up outlet to insure proper
operation during a power outage
8. Power up the R194 units, before step 9.
9. Using the supplied serial cable, connect it from the serial port on the R189
to the control input connection on the first R194. If using more than one
R194, connect the serial cable from the Control out connection of the first
R194 to the Control in connection of the second R194. Continue
connecting the Control connections to any additional R194's.
