Figure 1.  Connecting Keyboard to Multiplexer

1.

Remove the DIP switch cover plate from the rear of the keyboard (refer to Figure 1).

2.

Set the switches (refer to Figure 1 for switch locations).

ADDRESS
Set switches 1, 2, and 3 OFF. This is address 0, which selects the multiplexer
operating mode.

COMMUNICATION MODE
•

Set switch 4 OFF to enable polled communication mode. Use this for normal
keyboard operation.

•

Set switch 4 ON to put the keyboard in non-polled communication mode. Use this
when the keyboard communicates remotely over communications media that do
not support polled mode. These are any communications media that introduce
significant delay in transmitting data (for example, phone line transmission
systems). In non-polled mode, the keyboard can control multiplexers only. The
multiplexer server does not support non-polled mode.

The following parts are supplied:

1

KBD4000 keyboard

1

25-foot (7.6 m) data cable

The mode of operation depends on whether the keyboard is connected to a multiplexer or
to a server.

A single keyboard is plugged into the back of a Genex
MX4000 Multiplexer.

Up to four keyboards can be connected to the back of a
Genex MX4000SVR Multiplexer Server. Each keyboard
connected to the remote keyboard port requires a
KBDKIT(-X).
