For remote keyboard connections, use COM 5, 6, 7, or 8 for the CM6800-48X8 and COM 4 and 5 for the
CM6800-32X6. Each port can support up to eight KBD300A keyboards. Do not exceed 16 total keyboards
for the CM6800-48X8 and eight total keyboards for the CM6800-32X6.

A KBDKIT or KBDKIT(-X) is required to connect remote keyboards. Each kit contains two RJ-45 wall blocks
and a transformer. Use one wall block for each keyboard.

Refer to Figure 4 (CM6800-48X8 shown).

�

Pick a suitable location for each keyboard and wall block. Wall blocks must be within 6 feet (1.8 m) of
a suitable electric outlet. Do not mount the wall blocks yet.

�

Connect each keyboard to a wall block, using the supplied keyboard data cable.

�

Remove the wall block covers and wire the connections between each wall block. Connect to a final
wall block (which will be connected to the CM6800).

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 pair cable that
meets or exceeds the basic requirements for EIA RS-485 applications.

�

At each wall block, wire the KBDKIT or KBDKIT(-X) transformer to pins 3 and 4.

�

Replace the wall block cover. Secure the wall block to a suitable surface using the double-sided
sticky pad.

�

Set the address switches for each keyboard (refer to the 

Switch Settings 

section). (If using COM 7 or

8, the port settings on the CM6800 must be changed from the default settings. Refer to the CM6800
manual.)

�

Connect the final wall block to COM 5, 6, 7, or 8 on the CM6800-48X8 or COM 4 or 5 for the CM6800-
32X6 using a straight data cable (supplied with the CM6800).

�

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

�

To initialize the keyboard, wait five seconds after powering-up the CM6800, enter the number for the
monitor you are viewing, and press MON. The LED display shows the number entered.

NOTE:  You must re-initialize whenever power is cycled.
