2.2.1 Electrical Cable Connection
The two available cable connections on the electrical side are
for audio and data connections. Follow the proceeding
instructions in order to properly install your electrical
connections.
2.2.1.1 Audio Interface
The audio interface supports two channel high fidelity
transmissions. Two separate mono channels or one stereo
channel is transmitted in each direction. Line-level audio signals
are connected to the 285E units using twisted pair shielded
cable. The following steps illustrate the installation procedures
for audio devices.
To send audio signals, on the 285E-TRX module, at the
near-end and far-end locations, label and connect two twisted
pair shielded cables to the “AUDIO OUTPUT” connectors of the
line level audio source. On the 285E, connect the other end of
the cables to the front panel terminal block connectors labeled
“AUDIO IN”. For stereo channels, be sure to match the cables
at both ends (L to L, R to R), and make sure the connections
mate with the correct polarities (+ to +, - to -). (See Figure 2-2).
To receive audio signals, on the 285E-TRX module, at the
near-end and far-end locations, label and connect two twisted
shielded pair cables to the “AUDIO INPUT” connectors of the
line level audio receiver. On the 285E, connect the other end of
the cables to the front panel terminal block connectors labeled
“AUDIO OUT”. If using stereo channels, be sure to match the
cables at both ends (L to L, R to R), and make sure the
connections mate with the correct polarities (+ to +, - to -).
(See Figure 2-2).
