2.0 SCOPE
Coaxitron System 2000 is an improved version of the
original Coaxitron. Improvements include the following features:
1. When used with an AI700 Auto Iris Servo, three
latching functions rather than two are available: (a)
auto scan, (b) camera power and (c) auto/manual
iris.
The information contained within this manual covers
the installation and operation of the Coaxitron System
2000 (transmitter control and receiver).
Installation should be in accordance with all applicable
local and national electric codes, utilizing approved
materials only.
Please thoroughly familiarize yourself with the information in this manual prior to installation and operation.
3.0 DESCRIPTION
The Coaxitron System 2000 control system provides up
to 16 remote control functions without the need for
control cables other than for a dedicated video cable for
the normal transmission of a remote camera signal to the
local monitoring and control position. The Coaxitron
Control System lends itself to application in situations
where short-to-medium distances are involved and where
equalization of cable losses is not required.
Typically, these functions are:
1. Pan Left 9. Iris Open
2. Pan Right 10. Iris Close
3. Tilt Up 11. Camera Power On/Off
4. Tilt Down 12. Auto/Manual Scan
5. Zoom In 13. AUX 1 (Manual Iris)
6. Zoom Out 14. AUX 2 (Auto Iris)
7. Focus Near 15. AUX 3
8. Focus Far 16. AUX 4
Functions 1 through 10, 15 and 16 are momentary; that
is , they are only actuated while the associated control
switch located on the Coaxitron transmitter or front
panel is operated. Functions 11, 12, 13 and 14 are
latching; that is, camera power, auto scan, and auto/
manual iris are latching functions and remain on until
turned off. The latching iris function is not dedicated,
and with proper interfacing, it can be used for some
other latching function. Alternately, AUX 1, 2, 3 and 4
may be used as momentary functions to control such
things as lights or gates with proper external interfacing.
Up to ten functions can be operated simultaneously.
Functions 11 through 16 must be used individually;
although any one of these functions may be used simultaneously with functions 1 through 10.
2. When used with a CX900TLC Local Test Board
Plug-in Module, manual control of functions from
the receiver location plus the ability to check for the
valid reception of a given command from the
transmitter.
3. Pan/tilt, zoom lens and camera power control are
included on the main (video and logic) receiver
board, which eliminates malfunctions due to
miswiring or broken wires.
Coaxitron System 2000 provides the following standard functions on a single circuit board and chassis with
integral power supply:
1. Pan/Tilt (24 VAC or 120 VAC as ordered from the
factory)
2. Zoom Lens — Zoom, iris, and focus with adjustable speed (speed not remote controllable)
3. Camera power (24 VAC or 120 VAC as ordered
from the factory)
4. An open collector transistor output (latching) intended for use in manual override of an automatic
iris control.
4.0 INSTALLATION
Coaxitron System 2000 installation includes the connection of all coaxial cable to the proper connectors,
depending on your system configuration. Various connector assembly pin-out geometries are shown in Figure
4. Connector location and pin assignments are illus-
trated in Figure 5.
For optional auxiliary functions, consult the factory to
make the proper connections between the receiver, pan/
tilt and camera/enclosure.

4.2 CONNECTOR ASSEMBLY
Installation and/or testing will require you to assemble
the connector parts provided. Fabricate the interconnecting cable according to the following steps (reference Figure 4).
1. Slide part A of the cable clamp (item 1) over
the end of the cable (item 1, part C) with the
threaded end of the cable clamp facing the connector (item 5).
4. The contact pins supplied with the mating connector are the “crimp” type which may also
be soldered if you so desired (item 4).
5. After crimping or soldering the contact pins
to the conductors, push them into the proper
holes in the connector until they snap in place.
Note: Contacts cannot be removed from the connector without the use of the appropriate AMP extraction tool which is available from PELCO.
2. If the cable has a diameter less than 1/2 inch
(1.3 cm), slide the rubber boot (item 2) over
the end of the cable and pull through the cable
clamp to so that the boot encases the cable and
forms a good seal.
3. Strip back the cable jacket approximately 11/4 inches (3.2 cm) and separate the individual
conductors (item 3).

4.3 SYSTEM CONFIGURATIONS
Figure 6 shows the simplest system configuration utilizing the Coaxitron System 2000. This system consists of
the control transmitter, coax cable and receiver/camera.
This basic Coaxitron system is flexible in that it can be
expanded to control multiple camera sites when a hard
contact switching device is added.
COAXITRON
TRANSMITTER
COAXITRON
TERMINATE MONITOR
Figure 7 shows the addition of a manual video switcher
and one receiver/camera. In this example, the active
coaxial cable is terminated in the transmitter and the
inactive cables are terminated in the switcher. The
selected camera signal is fed to the Coaxitron transmitter, which then feeds the monitor. When a camera
selection is made, that video line is dedicated to the
transmitter that allows the associated Coaxitron receiver to be controlled. Functions such as auto/random
are latching and will remain on until turned off by the
transmitter.

Pelco Manual C550M-E (8/97) 7
A more complex system is shown in Figure 8. Here,
several control locations can serve a single camera
system.
Note: All transmitters, except the last one, must
be looping (unterminated) rather than terminating.
This monitor may also be used for sequential switching.
As in the previous configuration, any one transmitter
can assume control. If two or more control units are
activated simultaneously, erroneous responses are prevented by error detection circuitry in the associated
receiver.
In a system of this type, any one of the transmitters can
assume control because there is no priority provision. If
two or more transmitters are activated simultaneously,
error detection circuitry in the receiver will cause multiple commands to be ignored.
Figure 9 shows an even more complex system. In this
example, multiple transmitters are controlling multiple
receivers.
Note: All but the last transmitter and associated
switcher must be looping (unterminated). Transmitters and associated switchers should be physically adjacent to insure against signal deterioration
due to cable mismatch.
Video cables from the receivers are looped through the
first control station to the second. At the first control
station, a bridging-looping type sequential switcher
(except VA500 series) is used. The Monitor 2 output is
a hard contact switch, otherwise known as the bridged
output for continuous viewing or control selection.
The switchers depicted in Figure 10 are hard contact
devices and do not have isolation or bridging amplifiers.
In each case, the Coaxitron transmitter acts as the
isolation or bridging amplifier. Do not use VA500
series switchers with Coaxitron systems.
Note: For configurations where RG59 cable
length between the transmitter and receiver exceeds 750 feet, it is necessary to reset switch SW1
on the receiver board (PCB1500529) from SHORT
to LONG. The switch should be left in the SHORT
position when using shorter lengths of RG59 cable
or when using RG11 cable (see Figure 5). For
RG11 cable, the upper limit is 1800 ft. In any case,
these operating distances can be extended by using
the EA2000. See the table on page 26.
Coaxitron System 2000 basic interconnections between
the transmitter and receiver are shown in Figure 10. If
you have chosen a configuration that includes a switching device, refer to the manual provided with the switcher
for the appropriate connections.

5.0 OPERATION
In general, all operating controls on the transmitter are
self explanatory. With the exception of the ON/OFF
power switch and the 8-position joystick, all controls
are center-off, spring return paddle switches (momentary on-off-on).
5.1 FUNCTIONAL CIRCUIT DESCRIPTION
The basic functional concept of the Coaxitron system is
that 15 control pulses are fed in a reverse direction from
the control transmitter to the receiver located near each
camera station. These control pulses do not interfere
with the video monitor presentation because they occur
during the vertical blanking interval of the video signal.
The equipment is designed to operate with video cable
lengths up to 750 feet of RG59B/U (or equivalent), or up
to 1,800 feet of RG11. The SW1 switch prominently
located on the receiver board (PCB1500529), should be
moved to the LONG position when RG59B/U cable of
greater than 750 feet is used (see Figure 3).
Cable impedance matching is insured by the video
amplifier in the control receiver. Proper receiving
and termination impedance is likewise insured by the
terminating resistor in the control transmitter.
Any equipment placed between the remote and local
locations must be of the “loop-through” or “bridging”
type; power splitter or line amplifiers cannot be tolerated.
Response time of the system is normally less than 30
ms. Error detection circuitry is incorporated to immunize the system from externally generated noise. Under
extremely adverse environmental noise conditions response time may increase, and in the limit, control
functions can fail. Under such extreme conditions,
however, provision is made to inhibit all momentary
functions.
The proper function of the Coaxitron system depends
on the compatibility of two signals simultaneously
traveling in opposite directions in the same coaxial
cable. If the control signal is made large, compared to
the video signal, there is the risk that associated equipment will be adversely affected. If the control signal is
made small, compared to the video signal, it becomes
difficult to separate it from the video signal (and any
incumbent noise or hum). Therefore, the Coaxitron
system is designed to function with video and control
signals nominally equal.
Under such circumstances, reliable performance can be
predicted with cable lengths of 1,500 feet or more.
Beyond this distance, the control signal amplitude can
become attenuated sufficiently to make performance
marginal. Marginal performance is also approached if
the video signal is allowed to become excessive — the
dynamic range of the receiver video amplifier is one
limitation. Sending end distortion produced by the
coaxial cable is typically the major contributor to the
malfunctioning of a Coaxitron system. The amplitude
of distortion products is proportional to video signal
amplitude and is a non-linear function of cable length.
The influence of these distortion products upon system
performance is difficult to predict if signal amplitude is
allowed to exceed specifications.
Normally, auto-target or auto-iris functions will maintain a video level well within reasonable limits and
insure reliable performance. Often, however, automatic
or manual level settings may be made abnormally high
(perhaps to compensate for long cable losses or to
produce a picture with more contrast). An excessively
high video level setting can cause the Coaxitron control
system to fail completely — with all control functions
disabled. In order to prevent system failures due to
excessively high video levels, it is recommended that
cameras be powered by the receiver.
The Coaxitron System 2000 is designed to combat
prolonged loss of control due to the conditions described above by providing the following protective
functions:
1. Simultaneous commands from two different
sources are processed to insure that manual iris
control cannot be inadvertently selected in
place of automatic control.
2. A sustained (20 to 40 second) illegal command
condition results in (a) camera off,
(b) automatic iris, or (c) manual pan.
These functions greatly reduce the possibility of loss of
control and usually eliminate the need for service.
10 Pelco Manual C550M-E (8/97)
As an example, assume that the operator switches to
manual iris control and proceeds to open the iris excessively. The result can be a complete loss of control.
Within 20 to 40 seconds, camera power is automatically
removed (assuming this feature exists) and auto iris is
reinstated. Thus, distortion products are eliminated if
the camera power function is incorporated in the system
or reduced to a tolerable level if only the AUTO/
MANUAL iris function is incorporated.
5.2 TRANSMITTER
The transmitter is housed in a 1-3/4" high enclosure,
supplied as a desk top unit (rack mount available). Three
video connectors (J6, J7, J8) are located on the rear rail
(see Figure 10). J8 allows the user to loop the camera
signal from one transmitter to another, or to terminate
the signal by installing the appropriate resistor. Connector J7 accepts the camera signal from the receiver, and
J6 provides an output for monitoring equipment.

surface for entry of AC power line (120/230/24 VAC).
(See Figure 10.)
The INPUT video connector accepts the signal from the
camera and provides a 75 ohm termination.
The OUTPUT video connector is connected to the
transmitter input connector (J7) via a dedicated and
continuous coaxial cable. Proper termination of this
cable is vital to the operation of the equipment. Although loop-through connections in this cable are permissible, power splitter or line amplifiers cannot be
tolerated.
5.4 RECEIVER/TRANSMITTER
INPUTS AND OUTPUTS
The Receiver/Transmitter inputs and outputs are described as follows:
• Receiver Video Input
Normally, this is the video signal from the camera serviced by the receiver. The receiver provides a 75 ohm cable termination and an isolation
amplifier to prevent the control pulse train from
being fed to the camera. (See Figure 10.)
• Receiver Video Output
This output is fed to the transmitter video input
(J7) via 75 ohm coaxial cable. Active elements
or “splitters” in this cable run cannot be tolerated. (See Figure 9.)
• Receiver Power Input
All Coaxitron receivers may be powered by 24/
120/230 VAC as ordered from the factory.
The AC power input for 24 VAC operation must
be changed as described in Section 4.1.
Aux 3, 4 Paddle switch (momentary
functions)*
*External requirements are needed for operation
5.3 RECEIVER
The receiver and control function assemblies are contained in a “J-Box” housing. One end of the J-Box has
two video connectors (input and output) and CPC-type
control cable connector. Provision is made on this same
Pelco Manual C550M-E (8/97) 11
• Receiver Control Output
All control signals from the receiver are available from an AMP Series CPC output connector,
except for optional auxiliary functions. (See
Figure 10.)
• Receiver Control Output for 12 VDC Camera
Option
The usual output for camera power is 24 VAC
accessed at pins 9 and 14 of the 37-pin AMP
connector (see Fig. 5) where CAM AC HIGH
and AC LOW emerge as CAMERA INPUT
POWER. The output pin assignments remain the
same for 12 VDC camera power options, only
now pin 9 (WH) is positive (+) and pin 14 (WH/
YEL) is negative (-).
• Transmitter Video Input
The transmitter usually provides for the 75 ohm
termination of the cable from the receiver. However, the user may alter this termination in order
to loop through and terminate further downstream. (See Figure 10.)
WARNING: Power for enclosure models utilizing heater/blowers cannot be tapped off the secondary of the Coaxitron receiver transformer or off
of camera AC power (see Figure 5, Pins 9 and 14).
Instead,for example, enclosure power for these
purposes could be run off of the primary of the
Coaxitron transformer and routed to the enclosure
via unused Pins 15 and 16 of the 37-Pin connector.
Although the Coaxitron control system is immune to
transient or surge disturbances, its performance can be
impaired by the presence of large ground loop voltages
between the transmitter and the receiver. The amplitude
of ground loop potential that can be tolerated varies as
a complex function of cable center conductor resistance, video signal amplitude, and cable length. However, ground loop voltages that induce less than 0.5 volt
p-p into the video output of the receiver should not cause
the system to malfunction.
Factors that limit the distance over which the Coaxitron
can be used are transmission line attenuation and transmission line signal distortion
When signal attenuation becomes large due to excessive cable length, the differential amplifier in the
Coaxitron receiver can no longer detect the presence of
a control pulse train. The limitation can be overcome by
increasing the amplitude of the pulses generated by the
transmitter. This is not done without danger, however,
because associated equipment may be over-driven by
the larger signal. (Note that the presence of the control
signal is not restricted to the cable between the transmitter and receiver, but will be on all signal cables downstream from the receiver.)
It has been stipulated that loop-through connections are
permissible in the control link, and distribution or
equalizing amplifiers are not because of their
undirectional characteristics.
Pre-equalization of the camera signal prior to feeding to
the Coaxitron receiver is generally not practical because
of the dynamic limits in the receiver video amplifier.
Post equalization of the signal (transmitter output signal) is permissible, but probably not practical. It should
be kept in mind that although the camera signal has been
deteriorated by the transmission line, the control signal
has not. Therefore, the equalized control pulses will be
extremely large and probably cause an overload in some
part of the system downstream from the equalizing
amplifier.
In the absence of an assertive control command, the
transmitter is inactive. Thus, it is possible to control one
receiver from more than one control.
5.5 COAXITRON PREPOSITION
RECEIVER
In general, ground loop problems will seldom be encountered. However, potentials as high as 10 volts p-p
between ground connections within a single building
are not unheard of. If such circumstances arise, Pelco
recommends the use of its Model GIT100 Ground
Isolation Transformer. When inserted in the cable run
between two points of different ground potential, the
effect of this potential difference on the video signal is
reduced by more than 100 times with 200 feet, and more
than 20 times with 1,500 feet of RG59 type cable. More
than one GIT100 can be utilized in situations where the
common mode voltage (CMV) exceeds 10 volts p-p.
This transformer is passive and can easily be inserted
where required at any time.
12 Pelco Manual C550M-E (8/97)
Note: The Coaxitron preposition receiver is
designed for use with Coaxitron Matrix controls
only.
The Coaxitron System utilizes linear taper precision
potentiometers as the position feedback sensors. This
feedback voltage is digitized and stored in the receiver.
The storage of the presets is held in EEPROM and is
therefore nonvolatile.
Up to 32 presets can be stored in each receiver. Up to 8
T
presets can be activated by alarm contacts connected to
the receiver. There is also an open collector output from
the receiver to activate an external device (such as the
CSA764) when the alarm contacts are activated. Figure
11 shows the wiring for alarmed presets.
The pan/tilt will “nod yes” if the receiver reads the
feedback voltages (preposition lens) or “nod no” if it
does not read any feedback voltages (manual lens).
This routine is a good troubleshooting indicator of
incorrect wiring of the control cable.
If multiple alarms are activated, the receiver will sequence between the alarm presets at a 5 second dwell
time per preset.
Figures 12 through 14 provide pin-to-pin connections
for preset domes, pan/tilts and lenses to the Coaxitron
receiver that are available at this revision manual.
5.5.1 Power-up Routine
When a preposition receiver is first powered up, it has
a routine that it goes through to orient itself to the pan/
tilt and lens connected to it.
The routine first automatically operates the lens “zoom”
and “focus” functions.

The second part of the routine will operate the “pan left”
and “pan right” functions. The pan/tilt will “nod yes” if
it reads only one feedback voltage (pan/tilt with limit
stops) or “nod no” if it reads two feedback voltages (SL
pan/tilt).
The total routine takes approximate 45 seconds to
complete.
5.5.2 Creating Presets
At the present time the only Coaxitron system transmitters capable of creating presets are the CM7500, the
CM9500 Matrix and the MPT9500. Refer to the instructions in the product manuals (C584M, dated 2/90 or
later for CM7500 matrix, or C500M for CM9500 matrix
or C535M for the MPT9500) to create presets, if necessary.

5.6 AUXILIARY FUNCTIONS
The Coaxitron receiver is capable of operating up to
four (4) remotely activated auxiliary functions. Each
auxiliary output may be individually converted at the
receiver for momentary or latching operation. Refer to
Figure 15 for the desired jumper location. When in the
latching mode, activating the same AUX function will
toggle the function from on to off.
The AUX outputs are buffered to provide a continuous
10 VDC at 25 mA to drive small relays, lamps or some
other external device. Refer to Figures 16 and 17 for
examples of typical circuits used for auxiliary functions.
Note: The preceding two paragraphs pertain to
Revision J or newer Receiver/Driver Mother boards.
Figure 18 shows a typical connection using the latching
command to operate an AI700 or AI701 for auto iris or
manual iris operation. AUX 1 latches manual iris; AUX
2 latches auto iris.

5.7 AUTO/RANDOM OPERATION
The A9000 Auto/Random Scan module is a plug-in
P.C. board option (See Fig. 19 for board location) for all
Coaxitron receivers. This module provides two modes
for automatically controlling pan and tilts within preset
limits — Auto Scan and Random Scan. The Random
Scan and Auto Scan functions are controlled by the
same momentary switch on the control panel labeled
AUTO and MAN. The first activation of the switch to
the AUTO position will put the pan/tilt into Random
Scan. In Random Scan operation the pan/tilt will travel
between the preset limits with a random scan period of
about 0 to 60 seconds, and a random dwell period of
between about 4 seconds and a programmable 60 to 900
seconds. At the completion of a dwell period, another
random scan period is started. The direction of this scan
period is also randomly determined. When a pan limit is
reached, scan direction is reversed automatically. A
second activation of the AUTO switch will put the pan/
tilt into continuous duty Auto Scan. After approximately 1/2 hour of auto scan, the circuit will reset to
random scan. Commanding AUTO while in Random
mode causes a shift to Auto mode and starts the halfhour timer. Similarly, commanding AUTO while in
Auto mode causes a shift to the Random mode and zeros
the half-hour timer.
Advantages of random scan:
1. Because scan direction, scan period and dwell
period are unpredictable, unauthorized activities or intrusions are discouraged.
2. Because of the reduced duty cycle, gear train
wear, cable fatigue, drive motor wear and
temperature rise are reduced. These factors all
contribute to higher system reliability and increased equipment life.
2. Insert spacers into appropriate holes in the
motherboard and snap firmly into place.
5.8 CX900TLC MANUAL/TEST MODULE
The CX900TLC Manual/Test Board is a dual purpose
plug-in module (See Fig. 19 for board location) which
permits local operation of all functions directly from the
receiver unit, and also serves to verify that the receiver
and accessories are operating properly by providing
visual confirmation. This module also aids in troubleshooting receiver or transmitter operational problems.

6.0 TROUBLESHOOTING GUIDELINES
If you experience operating problems with either the
receiver or transmitter, first check all fuses and voltage
readings to make sure they are in working order. The
CX900TLC can be utilized to verify receiver functions
and accessories are operational.
7.0 MAINTENANCE
The Coaxitron System 2000 is engineered to provide
years of reliable service. The Coaxitron System 2000
has very few operator serviceable parts and we recommend that system components be serviced by a trained
technician or returned to the factory for repair.
There is little that can be done without the aid of an
oscilloscope. We recommend you contact your local
dealer or our Customer Service Department for assistance.
Copies of the Coaxitron System 2000 Maintenance
Manual (document number C550SM) are available on
request.
