Pelco Manual C527M-L (3/04) [ 17 ]
RS-422 Interface (CM6700)
Refer to Figure 6.
ᕡ
Remove the cover from the CM6700 SCU and verify that the DIP switches for COM 2 are set for
RS-422. Refer to the
COM 2 Port section in the CM6700 Installation/Operation Manual for setting the
switches. Reinstall the cover.
ᕢ Use an existing CM6700 keyboard to program the COM 2 communication port. (If there is no other
keyboard, use the one you are installing. Set all DIP switches OFF and plug the keyboard into the Lo-
cal Keyboard port on the back of the CM6700. Remove when programming is completed.) Refer to the
Setting COM 2 Communication Parameters section in the CM6700 Installation/Operation Manual for
programming instructions. Set COM 2 port parameters as follows:
Baud: 9600, Parity: Odd, Stop Bits: 1
ᕣ
Decide on a suitable location for the keyboard and wall block. The keyboard must be within 25 feet
(7.6 meters) 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 at this time.
ᕤ
Remove the wall block cover and make connections between the wall block and COM 2 of the
CM6700 SCU.
ᕥ
At the wall block wire the transformer to pins 3 and 4. Polarity is unimportant.
ᕦ
Replace the cover on the wall block. A double-sided sticky pad is provided to mount the wall block.
Secure 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 CM6700 (if not already powered). 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 dis-
play shows the number entered.
ᕫᕵ
Once you apply power to the keyboard and the CM6700 SCU, you can use the keyboard in the same
manner as a normal keyboard except that in ASCII Mode you cannot program the CM6700.
ᕫᕶ
Go to the Programming and Operation section and program and test for proper operation.
