Figure 2-13 Connecting Peripherals to a DEC423 MMJ Port

Connecting a Peripheral to the Asynchronous Modem Control Port

You can connect peripherals that use EIA-232 connectors to the asynchronous modem

control port on the back of the system unit. Alternatively, the supplied EIA-232 to

DEC423 adapter (H8575-A) allows you to connect peripherals that use DEC423

connectors. This port may be used as a terminal port as well as a modem port.

If you are connecting a peripheral to the asynchronous modem control port using EIA-232

cables, refer to Figure 2-14 and follow these steps:

a) Set the ON/OFF switch on the peripheral to the OFF (O) position.

b) Connect the 25-pin D-sub connector of the peripheral cable to the asynchronous

modem control port.

c) If the connector has screws on either side, tighten them using a small screwdriver.

d) Connect the other end of the peripheral cable to the correct port on the peripheral.

e) Set the ON/OFF switch on the peripheral to the ON position.
