There are two keyboard ports on the CM6700 SCU.

The LOCAL KEYBOARD port is for connecting a single keyboard within a distance of 25 feet (7.6 meters).

The REMOTE KEYBOARD(S) port is for connecting additional remote keyboards.

Connecting a Keyboard to the Local Keyboard Port
�

Use the data cable that is supplied with the keyboard. Plug one end of the cable into the RJ-45
connector on the rear of the keyboard and the other end into the LOCAL KEYBOARD port on the SCU
(refer to Figure 1). Set the keyboard switches according to the instructions in the 

Switch Settings 

sec-

tion. Go to step 2 to install remote keyboards, or go to step 10.

A KBDKIT or KBDKIT-X is required for this application. The KBDKIT consists of two RJ-45

wall blocks and a 120 VAC to 12 VAC transformer. The KBDKIT-X is for 230 VAC. Use one KBDKIT
for each keyboard.

Refer to Figures 1 and 2 for the following steps.

�

Decide on a suitable location for each keyboard and wall block. Keyboards must be within 25 feet (7.6
meters) of the wall block. Wall blocks must be within 6 feet (1.8 m) of the nearest suitable electrical
outlet. Do not mount the wall block at this time.

�

Run wall block interconnect cable (user-supplied) from the SCU to the closest keyboard location, then
to the next nearest location, and the next, etc.

Communication to the keyboards is RS-485. Maximum cable distance for RS-485 communication over
24-gauge wire is 4,000 feet (1,219 m). Pelco recommends using shielded twisted pairs cable that meets
or exceeds the basic requirements for EIA RS-485 applications.

�

Remove the wall block cover and make cable connections at each wall block.

�

At each wall block, wire the transformer to pins 3 and 4. Polarity is unimportant.

�

Replace the cover on the wall block. Secure the wall block to a suitable surface. A double-sided sticky
pad is provided to mount the wall block.

�

Set the switches for each keyboard according to the instructions in the 

Switch Settings 

section.

�

Plug in all keyboard data cables.

�

Plug the KBDKIT or KBDKIT-X transformer into a suitable outlet.
