Pelco Manual C1515M-A (11/01) 23
M DEVICES
M protocol devices (KBD960/KBR960 keyboards, ALM2064 Alarm Interface Units, and
REL2064 Relay Interface Units) can be connected to COM 3 on the CM6800.
If only one device is to be connected to COM 3, use the instructions for that device in the
following sections.
If more than one device is to be connected to COM 3, refer to the
Multiple M Devices
section.
Connect M devices to the CM6800 with straight cables. Four straight cables and one
reversed cable are supplied with the CM6800 (save the reversed cable for connecting a
Genex Multiplexer, if applicable).
M Devices Addressing
Each M device connected to the CM6800 must have a unique local address within a range
of 1-16. Use the hardware DIP switches to set the appropriate ALM2064 and REL2064
local addresses. Specify the appropriate KBD960/KBR960 local address through the
keyboard Setup Mode after you complete the system installation (refer to the
System Start-
Up
section).
For use with the CM6800, Pelco recommends numbering M devices in a sequential order.
In a sample application, with two of each M device, you might assign local addresses as
follows:
M device local addresses: Default Recommended for CM6800
KBD960/KBR960: 1 1, 2
REL2064: 1 3, 4
ALM2064: 1 5, 6
