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.
Currently the CM9760-PEX supports:
1. Pelco Camera Receiver/Drivers
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.
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).

3.0 INSTALLATION
3.1 HARDWARE
3.1.1 Card Expansion Installation
Each port expander card has its own microprocessor and power regulator. No
communication exists between port expander cards.
Cards are installed from the front of the unit after the quick-disconnect screws which
hold the front panel in place are loosened (refer to Figure 2).
Cards can be installed into any free slot in the CM9760-PEX Port Expander; that is,
there is no set position where the first card must be installed. The five Input Ports
located on the right rear of the unit, however, are associated with specific physical
card expansion positions as indicated in Figure 1.

3.1.2 DIP Switch Settings
Each port expansion card, before being installed into the CM9760-PEX card cage
should be properly configured with respect to DIP switch settings. The switch
setting positions configure communication attributes as well as condition the PEX
for the device type connected to each expansion card. These choices are
illustrated in Figure 3.
3.1.3 Device Connections
Each CM960-PEX Port Expander card (Input 1 through Input 5) on the right rear of
the PEX card cage must be connected to a separate RS-422 COMM port located
on the rear of the CM9760-CC1. The port on the CC1 is configured for eight data
bits, one stop bit and even parity. Baud rates are chosen according to the
parameters spelled out in Figure 3.
The connection details for devices connected to the port expander are detailed in
the next few sections.

3.1.3.1 Connection Between a CM9760-PEX and a
CM9760-CC1
The connection of a CM9760-PEX and a CM9760-CC1 is illustrated in Figure 4.
Every Port Expander card input port requires a separate connection to a comm port
(RJ-45) on the CM9760-CC1.
3.1.3.2 Connection Between a CM9760-PEX and
Pelco Receiver/Drivers
NOTE: DO NOT connect a mix-
ture of different receiver/driver
types to the same CM9760-PEX
Port Expander card.
The connection of a camera receiver/driver to a comms port on the CM9760-PEX is
illustrated in Figure 5. Up to 16 of the same type of camera receiver/drivers can be
connected to one comms port on the CM9760-PEX.
NOTE: The connection devices and/or ports used in the illustrations that accompany the next few sections are those of
the ports located on the device itself, rather than those located at either end of the connecting cable.

3.2 SOFTWARE
3.2.1 Address Details
Normally, up to 16 camera receiver/drivers can be connected to one SerCom 8 port
on a CM9760-CC1; however, up to 128 camera receiver/drivers can be connected
to the same port through expansion by using a Port Expander. Camera receiver/
drivers are numbered from 1 to 16. To uniquely identify each camera receiver/driver
connected via a Port Expander Card, the receiver/driver must be numbered from 1
to 128.
Up to 16 camera receiver/drivers can be connected to each port on the CM9760-CC1.
These receiver/drivers are addressed as per normal; that is, from 1 to 16 (refer to
the appropriate receiver/driver manual for instructions on setting receiver/driver
addresses). The SET9760 program (part of the CM9760-MGR package) is used to
number the camera receiver/drivers from 1 to 128. The receiver/driver address and
the port on the CM9760-PEX the receiver/driver is connected to is used to uniquely
identify each receiver/driver. Table A details how camera receiver/drivers are
numbered from 1 to 128. In each instance the receiver address can be computed
according to the following formula, if you know the receiver/driver address and the
port to which it is connected on the Port Expander.
EXAMPLE: A camera receiver/driver has an address of 12;
It is connected to comm port 7 on the CM9760-PEX.
The allocated address would be 108 and is computed according to the following
formula (you may also use the lookup table in Table C):
Address
=
=

=
Receiver/driver address + [(Comm Port # - 1) x 16]

3.2.2 Software Considerations
We now expand the previous section (using receiver/drivers as the attached
device) to include the configuration of the necessary software files that need to be
setup before successful operation of the PEX can be realized.
Two Setup files in the SET9760 program need to be adjusted if a CM9760-PEX
is connected to the CM9760-CC1. These files are the Comms (.SCP) and the
Camera file (.CAM). Refer to the CM9760-MGR manual for detailed instructions
on programming these files. Table A is can be used to find the number allocated
to camera receiver/drivers connected to a CM9760-PEX port expander.
Figure 9 illustrates the Comms (.SCP) file where communication parameters for
the port that the PEX is connected are configured. Since we know that the device
type attached to the expansion card for this port are receiver/drivers, an equipment
number is entered to reflect this (refer to the Figure 9).

Figure 10 illustrates the other file we previously mentioned-the camera (.CAM) file.
It is here that address parameters for each attached receiver/driver is uniquely
identified. Also note that this file is used to configure multiplexers, if needed. Refer
to the “type” pull-down menu through which you scroll to select the device type. In
our example, we are using the CAMERA selection.

4.0 GUIDELINES FOR PORT EXPANDER USE
The following points are listed as Pelco recommended guidelines for port expander
use. The reason the port expander exists at all is to extend the current port limit past
that physically allowed by the CM9760-CC1. Even though, the 32 port limit imposed
by the CC1 is usually sufficient for most system configurations, the advent of
extremely large system configurations made the port expander a necessity. That
being said, the guidelines are as follows:
1. Do not use a port expander until all or as many as possible of the available
sercom ports on the CC1 are used.
2. If it becomes necessary to use a port expander, use the port expander to hook
up those pieces of equipment that you have the largest number of.
3. If you have several different equipment types, all of which are candidates for
connection to a port expander, then the following – in order of hook-up
preference – is recommended by Pelco:
a. Receiver/drivers
b. Multiplexers (if necessary)
c. Keyboards
One should not hesitate to use the port expander to extend port density when more
receiver/drivers need to be introduced for system expansion, for this is the primary
reason the port expander was created.
One should be less hesitant to attach multiplexers and keyboards as indicated in
the “order of preference” hook-up in step 3 above. In particular, one should avoid
attaching addressable multiplexers (those capable of being daisy-chained) to a port
expander. Not that it could not be done, but that it would be a waste of resources.
For keyboards, special programming considerations are required. If you can’t avoid
using the port expander to attach keyboards, then follow the detailed programming
instructions contained in the CM9760-MGR manual.
