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.
