instructions for appliances intended to operate from
battery or other power sources.
Grounding
This CCTV product is equipped with a 3-wire “grounding” type plug, having a third (grounding) pin. This plug
will only fit into a “grounding” type power outlet. This
is a safety feature. If you are unable to insert the plug
into the outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the “grounding” type plug
since it is provided to ensure your safety.
Water and Moisture
Do not use this CCTV product near water - for example,

use only mounting accessories recommended by Pelco.
Cart & Stand
An appliance and cart combination should be moved
with care. Quick stops, excessive force, and uneven
surfaces may cause the appliance and cart combination
to overturn.
Power-Cord Protection
Power-supply cords should be routed so that they are
not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to
cords at plugs, convenience receptacles, and the point
where they exit from the appliance.
Overloading
Do no overload wall outlets and extension cords as this
can result in a risk of fire or electric shock.

4.0 INSTALLATION
4.1 INSTALLATION PREPARATION
Before installing your CM8500 system, it is necessary
to know how the system will be configured. This information is needed not only for the hardware installation, but is also necessary when programming the
CM8500 system.
Section 5.5.1 contains important information and blank
forms that will assist you in preparing for the installation. Refer to this section prior to installing your
CM8500 system.
If you have the CM8505R keyboard controller, mount
it securely into a suitable equipment rack or frame, using the supplied rack mount screws and washers. Keep
in mind the visibility and accessibility of the control
functions while installing the keyboard.
4.3 SYSTEM HOOKUP
IMPORTANT NOTE: Remove the paper
between the battery contacts on the CPU card
if it has not been removed. Refer to Figure 8
and Sections 4.3.3.1.1 and 4.3.3.1.3.
4.3.1 General
4.2 MOUNTING
The CM8502A-1 and CM8503A-1 Card Cage assemblies come pre-assembled with all circuit cards installed
and tested, ready to mount in standard 19-inch EIA racking consoles. The card cage will take 5.25 inches (13.34
cm) of vertical rack space. If ordered, individual spare
circuit cards are shipped separately. See Section 4.3.3
for instructions on individual circuit card installation
and setup.
NOTE: If you are installing the card cage in
a 19-inch rack, remove the 6-32 flathead screw
from the top of the front panel. This will allow
you to remove the front panel after the card cage
is installed in the rack.
NOTE: After installing the card cage, connect the ground lug on the back panel to earth
ground. The ground lug is located on the left
side above the ground symbol .
NOTE: Make sure the fuse module on the
rear of the card cage is installed for the correct
voltage.
The System 8500 is a third-generation Coaxitron® system, and therefore only requires a single coaxial cable or
fiber* to be installed from the main card cage to each camera location. The Coaxitron® system will receive the video
signals from each individual camera and will use the same
coaxial cable to send data to the receiver/drivers located
at or near the camera sites. Fixed camera locations do
not require the receiver/driver unless the use of auxiliary
functions is desired. Camera power can be derived from
the receiver, which is normally powered by local 120
VAC. Refer to Pelco Specification Sheet C550 for details of receiver capabilities and requirements.
In addition to being a Coaxitron® system, the CM8500
also can support Pelco Wiretron receivers or Pelco Spectra™, Legacy® or Intercept® receivers that have been
configured for control via RS-422. Wiretron operation
requires the CM8506 option board; RS-422 Spectra™,
Legacy® and Intercept® receivers require the CM8507
option board.
* NOTE: Check with your fiber-optic equipment
manufacturer for specifications and type of
equipment appropriate for compatibility with
Pelco Coaxitron® transmitters and receivers.
Figure 2. CM8505R Dimension Drawing
Pelco Manual C501M-B (10/97) 4-1
4.3.2 Keyboard to CPU Hookup
Up to eight (8) independent keyboards may be installed.
The backplane of the main card cage has eight (8) ports
that correspond to the keyboard inputs (refer to Figure
2A). If the supplied 8-conductor flat cable assembly is
used, it only requires that one end be plugged into a
port on the CPU and the other into the port on the rear
of the keyboard. (On the CM8505R keyboard, it doesn’t
matter which port you use on the keyboard. Two connectors are provided to support the daisy chaining of
keyboards, but this feature is not currently available.)
If user-supplied cabling is installed, then the CM9505J
adapter kit should be used to facilitate installation at
both the CPU and keyboard locations. (See Section
4.3.2.4 for wire-run distance specifications.)

4.3.2.1 CM9505UPS/CM9505J
Installation
4.3.2.3 CM9505J Wire/Pin
Configuration
The CM8502A-1 and CM8503A-1 Card Cages each
offer a total of eight (8) individual keyboard communications ports. Normally one keyboard utilizes one
communications port. Communications between each
keyboard and the CPU consists of two (2) balanced
differential data pairs and ±12 VDC supply voltages
together utilizing seven conductors. The keyboards are
supplied with 25-foot (63.5 cm) pretested interconnect cables with pre-assembled RJ-45 modular 8-pin
male connectors. Within many installations, it is necessary to install system keyboards at remote sites. The
CM9505J Junction Box allows you to convert the keyboard data cable into a set of cabling that can be run
through conduit (if necessary) for significantly greater
distances by eliminating the keyboard power connections and only running the data. The CM9505UPS reintroduces keyboard power at the keyboard end of the
cabling. See Figure 5. For distances of over 2,000 feet
(609.6 m), Pelco recommends using the CM9505UPS422 power supply/data repeater at the middle of the
run of wire in addition to the CM9505UPS.
4.3.2.2 Pin Configuration
Please refer to Figure 3 for specific pinout/wiring information and make connections accordingly.
NOTE: For data connection only, do not use
connection pins 3 thru 6.
Note that the pin assignments on the CM9505J wire
connection do not match the RJ-45 modular connector.
Make connections accordingly. (The color information
printed on the CM9505J PC board has no r elevance in
this application.)

4.3.3.1.5 Installing Option Boards
The CM8500 is factory-equipped as a Coaxitron compatible only system (unless requested differently). The
CM8500 is also capable of transmitting two-wire control information in RS-422 or Wiretron formats. To
make use of the system’s two-wire capabilities, the appropriate Pelco CM8500 Option Board must be
installed to the system buffer board.
CM8506 CM8500 Wiretron compatible option
board
CM8507 CM8500 RS-422 compatible option
board
Both option boards install into the CM8500 system
using the same procedures. It is important to note that
only one option board can be installed, making the system either Coaxitron®/Wiretron compatible or
Coaxitron®/RS-422 compatible. The system cannot
work with all three information formats at the same
time.
NOTE: The CM8506/CM8507 option boards
are transmit-only units. Only the appropriate
control signals are generated from the option
boards.
4.3.3.1.6 Option Board Receiver
Connections
When working with CM8500 optional data formats,
keep the following in mind when making the two-wire
connections to the receivers.
The CM8500 system offers no receiver addressability.
Home runs are required for each receiver in the system, and each receiver (if addressability applies to the
receiver) must be set to address 1.
The following two-wire connections
must be made:
When using the CM8506 Wiretron compatible option board, the “+” output for the camera that is to be
controlled with a Wiretron receiver must be connected
to the “high” input on the Wiretron receiver. The “-”
output is to be connected to the “low” input on the
Wiretron receiver.
With the CM8507 RS-422 compatible option board,
the “+” output for the camera that is to be controlled
with an Intercept® or Legacy® receiver is to be connected to the “RX+” input on the Legacy® or Intercept® receiver. The “-” output is to be connected to
the “RX-” input on the Legacy® or Intercept® receiver .
Option Board Physical Installation
The option boards are easy to install and should take
only a minimum of time. After turning off system power
and removing the buffer board (see section 4.3.3.1.4),
notice on the un-populated side of the buffer board there
are three (3) plug-in connectors and five (5) hex
spacers. The populated side of the option board (either the CM8506 or CM8507) has the matching male
pin connections and five mounting holes.
Line the female plug-in connectors and standoffs on
the buffer board with the male pin connectors and
mounting holes on the option board. Gently press the
boards together making the plug in connections. Use
the five (5) supplied mounting screws to firmly secure
the option board to the buffer board.
Make the appropriate jumper settings on the buffer
board (each receiver that is compatible with the new
option board must have jumpers set on the buffer board
appropriately). Reinstall the new buffer board/option
board assembly into the CM8500 card cage. See section 4.3.3.2 for jumper setting information.
Again, make sure all addressable receivers are set to
address 1.
IMPORTANT: After the Option Board has
been installed, and the individual jumper selections have been made for each receiver, you
must program the system software to match
the individual receiver data formats. Refer to
Section 5.5.2.4 for Receiver T ypes Pr ogramming Screen information.
Pelco Manual C501M-B (10/97) 4-9
4.3.3.2 Setting Termination on
Video Inputs
4.3.3.3 Determining and Setting
Monitor Output Assignments
The termination settings for the 32 video inputs are individually assigned on the Buffer Card. There are 64
jumpers located on the component side of the board,
two jumpers for each video input (designated V1
through V32). Refer to Figure 9. The board will have
to be removed from the motherboard in order to change
the setting(s). Follow the instructions for board removal
and replacement in Section 4.3.3.1.4 and refer to Figure 9 when setting the jumpers. For more information,
refer to Section 4.3.3.4.2.
NOTE: Jumper positions 1 and 2 apply to the
terminating/looping status of the individual
video inputs. Jumper positions 3 and 4 apply to
the Coaxitron®/two-wire compatibility of the
individual receiver.
Monitor output numbers automatically correspond
to the slot that the Input/Output board is installed.
The first monitor slot is the one just forward of the
Buffer Card slot. The last monitor slot is located in
the forward-most position. No other settings are
necessary.
4.3.3.4 Camera Location to Video
Input Hookup
Since the CM8500 is a Coaxitron® system, each camera input that has a Coaxitron® receiver requires only a
single coaxial cable (or fiber) to transmit both video
and camera control signals. Follow camera manufacturers’ recommendations for maximum allowable distances for their equipment.

4.3.3.4.1 Cable Selection
Coaxitron requires a high quality solid copper core coaxial cable with at least 95-percent copper braid shield.
Copper-clad steel center conductor is not recommended,
nor is aluminum shield. Such construction is generally
recognized as not being adequate for baseband CCTV
systems. This type of cabling is meant for RF MATV/
CATV type systems only.
4.3.3.4.2 Termination
If there is any equipment, such as a spot monitor, between the video input of the CM8500 and the video
output from your camera or receiver/driver, make sure
that these devices are set for looping, or high impedance. Terminate the video input to the CM8500. Here,
the CM8500 is the last piece of equipment.
Camera Monitor CM8500
Coaxitron is sensitive to improper termination and care
must be taken to ensure proper installation. When a
video output from a camera or receiver/driver goes directly to a video input of the CM8500, the video input
must be terminated with 75 ohms. However , if there is
more than one piece of equipment in the video path,
only the last piece of equipment is terminated. Terminating more than one piece of equipment (double termination) causes loss of signal.
For example, if a video input to the CM8500 is going
to be looped out to the input of another device, place
the jumper on the buffer card in the CM8500 in the
looping position and terminate the input of the device
receiving its signal from the CM8500. In this case the
CM8500 is between the video source and the final piece
of video input equipment.

Input termination
Video devices placed between the CPU and receiver/
driver must be passively looping and not use an amplified looping scheme. Some quad devices and VCRs use
this scheme. The amplified devices are not bidirectional
and therefore do not pass the Coaxitron® control signals. Should these devices need to be installed they must
utilize video that has first looped through the matrix
inputs .
See Section 4.3.3.2 for setting the termination jumpers.

4.3.3.4.3 Ground Loops
One other precaution to take prior to final connections
being made is to check all input coaxial cables for the
presence of possible ground loop voltages. Sync, video,
control functions, and/or system electronics may be adversely affected by a ground loop condition. Call Pelco
if unable to correct any ground loop problems. Do not
connect cables to input connectors if ground loop voltages are present between CPU and camera sites or between camera sites through the CPU. Pelco manufactures the GIT100, ground isolation transformer, to help
alleviate ground loop problems in Coaxitron®-based
equipment. The use of fiber optics is also another means
to eliminate ground loops in a system.
4.3.3.4.4 Hookup
After ensuring that the above conditions have been met
and that all precautions have been observed, the coaxial inputs from the camera locations can be connected
to the input connectors on the backplane of the card
cage.
Be sure that each connection is secure and that the connectors are properly installed.
It is always good installation practice to mark or number all cabling. If system troubleshooting is necessary
and cables need to be disconnected, system downtime
can be minimized with a well organized cable identification system.
4.3.6 Installation/Connection of
CM8532 Alarm/Relay Interface
4.3.6.1 Alarm/Relay Interface Kit
Installation
The Alarm/Relay Interface Kit contains the Alarm/
Relay Interface Board (with ribbon cables attached)
and all hardware needed to secure the board and connectors. The Alarm/Relay Interface Board mounts
onto the Backplane of the CM8502-1 or CM8503-1
Card Cage (refer to Figure 6).
NOTE: To install the board, the top cover as
well as the CPU and buffer boards need to be
removed.
Connect the 10-pin connector from the Alarm/Relay
Interface board to the backplane of the matrix card cage.
Note that the connector is keyed and that the edges of
the connectors should match (i.e., that the connector
has not shifted over one way or the other).
Once connected, secure the Alarm/Relay Interface
Board to the standoffs with the hardware provided. Once
secured, remove the blank-off plate covering the connector slots and mount the alarm and relay interconnect ribbon cable connectors to the card cage. Refer to
the following information for the proper location of each
connector.
Alarm/Relay Interface Board Card Cage
4.3.4 Connecting Keyboard to
the Data Monitor
Each keyboard will utilize a system monitor output for
programming and keyboard feedback. Select one monitor output at the keyboard location to be the data monitor
and connect that output from the card cage to the keyboard video input connector. Connect the monitor output
from the keyboard to the appropriate monitor and ensure
correct termination (75 Ohm). Refer to Figure 10.
4.3.5 Connecting Other System
Monitors
All other system monitors may be interconnected to
the video output BNC terminal(s) of the card cage with
the appropriate length and type of coaxial cable or
fiber-optic interface equipment. The video output of
the CM8500 is a standard NTSC 1V p-p video signal.
Again, ensure for proper 75-Ohm termination at the
monitor(s) or other video processing equipment.
