Pelco CM6800E-48X8 manual Multiple M Devices Local Connection

Multiple M Devices

Multiple M devices (KBD960/KBR960, ALM2064, and REL2064) can be connected to COM 3 on the CM6800E, either as local devices or remote devices (when connecting two KBD960/KBR960 keyboards to the CM6800E, you must use a remote connection).

Multiple M Devices: Local Connection

1.If you are connecting a KBD960/KBR960, connect it to the CM9505UPS with the straight cable supplied with the keyboard. Then connect the CM9505UPS to the IN port on the next unit (either the ALM2064 or the REL2064) with a 6-foot (1.8 m) straight cable (supplied with the CM6800E).

2.Connect each ALM2064 and REL2064 unit to the next unit with a 6-foot (1.8 m) straight cable (supplied with the CM6800E) from the OUT port to the IN port on the next unit. You can connect a maximum of four ALM2064 units and four REL2064 units to the CM6800E.

3.Connect the last unit to the CM6800E with a 6-foot (1.8 m) straight cable (supplied with the CM6800E) from the OUT port to COM 3 on the CM6800E.
