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).
Depending on the specific signal requirements of the system peripheral devices, 3-, 4-, or 7-wire
connections can be made. Figures 4-3 through 4-5 show the cable configurations for these
connections. Figure 4-6 shows the pinouts for a modem cable.
