Pelco Manual C529M-D (9/03)
INSTALLATION
There are two keyboard ports on the CM6700 Switcher/Control Unit (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
1 Use the data cable that is supplied with the keyboard. Plug one end of the cable into the RJ-45 con-
nector on the rear of the keyboard and the other end into the LOCAL KEYBOARD port on the SCU
(refer to Figure 2). Set the keyboard address according to Table B on page 6.
Go to step 2 to install remote keyboards, or go to step 10.
Connecting Keyboards to the Remote Keyboard(s) Port
NOTE:
A KBDKIT or KBDKIT-X is required for this application. The KBDKIT consists of two RJ-45 wall
blocks and 120 VAC to 12 VAC transformers. The KBDKIT-X is for 230 VAC. Use one wall block for each
keyboard.
Refer to Figures 2 and 3 for the following steps.
2 Select a suitable location for each keyboard and wall block. Wall blocks must be within 6 feet (1.8 m)
of a suitable electrical outlet. Do not mount the wall block yet.
3 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.
4 Remove the wall block cover and make cable connections at each wall block according to Figure 3.
5 At each wall block, wire the transformer to pins 3 and 4. Polarity is unimportant.
6 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.
7 Set the address switches for each keyboard according to the instructions on page 6.
8 Plug in all keyboard data cables according to Figure 2.
9 Plug the KBDKIT or KBDKIT-X transformers into a suitable outlet.
10 To initialize the keyboard, wait five seconds after power-up, enter the number for the monitor you are
viewing (1-4), and press MON. The LED display shows the number selected.
NOTE:
You must re-initialize whenever power is cycled.
