5.2 Connecting Asynchronous Terminals
The Command Port includes an interface
connector, so you can connect an asynchronous
terminal. The interface connector also lets you
control multiple Multiserver 500s from a single
terminal in a daisychain fashion.

As shown in Figure 5-2, there are two RJ-45-type
Command Port connectors located on the rear
panel of the Multiserver 500: CMD IN and CMD
OUT. Cable requirements and pinouts are detailed
in
Section 5.4
. If your installation includes a single
Multiserver 500, connect the asynchronous terminal
to CMD IN. You will need an RJ-45 to DB25 adapter
to connect the cable to the asynchronous terminal.
NOTE: In a single-unit installation, the device
number must be left at its default value of 0,
and you must strap the Multiserver 500 for
the low-impedance position. Strapping
details are covered in Section 5.3.
