AT-OMNI-121 / AT-OMNI-122

The same port that provides RS-232 connections also supports bidirectional IR pass-through, allowing a device to
be controlled from either the headend or the decoder endpoint. This step is optional. Either the top three or bottom
three set of terminals can be used for IR. Only the
RS-232 2
port (bottom set of connectors) supports both RS-232
and IR. Therefore, this port must be used for IR connections. Refer to
for more information.
