2.0 DESCRIPTION
The Pelco CM9760-PEX (Port Expander) is designed to increase the number of
devices that can be connected to a CM9760-CC1, using additional serial
communication channels to increase port density.
NOTE:
Each expansion card and
it associated eight ports can have,
at most, one device type at a time
connected to any one or all eight
ports; that is connection of two or
more device types on one card is
not permitted.
Currently the CM9760-PEX supports:
1. Pelco Camera Receiver/Drivers
2. Pelco Keyboards
3. Multiplexers
Pictured in Figure 1 is a rear view of a fully populated CM9760-PEX. As indicated
by the rear panel subdivisions, the Pelco port expander can be configured with up
to five port expander cards. Each input port (1-5) is associated with a
correspondingly numbered expansion card in the illustration below.
Each port expander card, in turn, is designed to expand any available RS-422, RJ-45
COMM port located on the rear of the CM9760-CC1 from one to eight RS-422 ports
on the rear of the CM9760-PEX.
Each of the eight ports that are part of the expansion, have the same functionality
as that of the original port on the rear of the CC1. Of course, a few new rules
regarding port grouping need to be obeyed (for example, refer to the margin note).
Any one of the eight ports associated with any installed expansion card can
accommodate:
1. Up to 16 camera receiver/drivers (up to 128 per port expansion card).
2. One CM9760-KBD (up to eight per port expansion card).
3. One Multiplexer (up to eight per port expansion card).
