Pelco Manual C527M-L (3/04) [ 21 ]
RS-485 Interface (CM6800)
Refer to Figures 8 (CM6800-48X8 shown) and 9.
ᕡ
Use an existing CM6800 keyboard to program the COM 4, 7, or 8 communication port (CM6800-48X8)
or COM 4 communications port (CM6800-32X6). (If there is no other keyboard, use the one you are
installing. Set all DIP switches OFF and plug the keyboard into the Local Keyboard port on the back of
the CM6800. Remove when programming is complete.)
ᕢ
Do the following to program the COM port:
a. Press the PGM key. At the prompt, enter the password (default is 2899100). The CM6800 Main
Menu appears.
b. Select PORT. The Set Serial Port screen appears.
c. Select the number of the desired port.
d. Set COM port parameters as follows: Device: ASCII, Type: RS-485, Baud: 9600, Parity: Odd, Data
Bits: 8, Stop Bits: 1.
e. Select RETURN, and RETURN again.
ᕣ
Decide on a suitable location for the keyboard and wall block. The keyboard must be within 25 feet
(7.6 m) of the wall block. The wall block must be within 6 feet (1.8 m) of the nearest suitable electrical
outlet. Do not mount the wall block yet.
ᕤ
Remove the wall block cover and make connections between the wall block and COM 4, 7, or 8 of the
CM6800-48X8 or COM 4 of the CM6800-32X6.
ᕥ
At the wall block, wire the transformer to pins 3 and 4. Polarity is unimportant.
ᕦ
Replace the cover on the wall block. Use the double-sided sticky pad to mount the wall block to a
suitable surface.
ᕧ
Set the keyboard DIP switches according to the instructions in the Switch Settings section.
ᕨ
Plug in the keyboard data cable.
ᕩ
Plug the KBDKIT or KBDKIT-X transformer into a suitable outlet.
ᕫᕾ
Apply power to the CM6800 (if not already powered). To initialize the keyboard, wait five seconds
after power-up, enter the number for the monitor you are viewing (1-8), and press MON. The LED
display shows the number entered. Once you apply power to the keyboard and the CM6800, you can
use the keyboard in the same way as a normal keyboard except that in ASCII Mode you cannot
program the CM6800.
ᕫᕵ
Go to the Programming and Operation section and program and test for proper operation.
