4.5 Connecting Peripherals

The following subsections contain information on the following tasks:

• Connecting peripherals to a DEC423 MMJ port

• Connecting a peripheral to the asynchronous modem control port (port 2)

• Connecting peripherals to an optional asynchronous port

• Connecting peripherals to an optional synchronous port

4.5.1 Connecting Peripherals to a DEC423 MMJ Port

Note

When the system is shipped, MMJ ports 0 and 1 are covered with an

arrow label identifying port 3 as the console port. When port 3 has

been identiﬁed, the OPA0 arrow label may be removed.

To connect peripherals that use DEC423 cables (BC16E) to MMJ ports 0, 1, or

3, follow these steps:

1. Set the on/off switch on the peripheral to the off (O) position.

2. Connect one end of the DEC423 cable to either MMJ port 0, 1, or 3 (see

Figure 4–3).

Note

In some countries, the peripheral cable has an earth drain wire.

Connect this earth drain wire to the grounding pillar above MMJ port

1 using the screw provided with the cable.
