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.
