Two Port Operation
•
For two- port operation, two digital transmission paths are required, so both the
PORT 1 and PORT 2 plugs mate to the TA/CSU digital connections. The TA/CSUs
may be separate for each path, or may be a single unit with two data ports. In either
case, the system automatically sorts out which channel is which and therefore it is
irrelevant which plug goes to which port.
•
For two- port operation in the
MONO/DUAL
mode, audio channel A corresponds to
PORT 1 and audio channel B corresponds to PORT 2, and both are used.
•
For two- port operation where the receive mode is set to L3 MONO only the data
received on PORT 1 will be decoded, although this audio will appear at both the A
and B receive audio jacks.
