Installation
1. Mount the R194(s) into the rack.
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 Lout audio connections from the R189 to the L+ and L-
connections of the EAS Audio in connector of the R194. If you want the
EAS audio to play on the right channel, you will also connect Rout
connections from the R189 to the R+ and R- connections of EAS Audio in
connector of the R194.
5. 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. 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.
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.
See the following wiring diagram for more details.
Programming
There is no programming to be done in the R194. However, the serial port on the
R189 needs to be programmed for the proper protocol.
Programming the R189 serial port:
1. Log into the R189 One-Net.
2. Go to Setup, Video/CG and select the R194 serial protocol at the top of the
page.
3. Click on the “Accept Changes” button at the bottom of the page to save your
changes.
4. That completes the programming.
