To “Y” off the RS422 signals put the incom-
ing (source) RS422 and outgoing RS422
(going to next device) wires into the same
terminals. The total length of the standard
RS422 chain can be up to 4,000 feet.
This type of configuration is ideal for multi-
building campus environments where a
DL1142 can be located in a phone room of
the building and drive RS422 devices for
the whole building.
The output of the DL1142 can drive up
to 32+ standard RS422 devices at up to
12,000 feet down the line.
