Device Wiring
Device wiring is dependent on the specific signal requirements of the
system peripheral devices. Cable connectors plugged into the DB-25 port
module ports must have a male DB-25 connector. The connector on the
opposite end of each cable should mate to the peripheral device port
(terminal, printer, personal computer or modem).
