3.0 DESCRIPTION  
Coaxitron System 2000 provides the following stan-  
dard functions on a single circuit board and chassis with  
integral power supply:  
TheCoaxitronSystem2000controlsystemprovidesup  
to 16 remote control functions without the need for  
control cables other than for a dedicated video cable for  
thenormaltransmissionofaremotecamerasignaltothe  
local monitoring and control position. The Coaxitron  
Control System lends itself to application in situations  
whereshort-to-mediumdistancesareinvolvedandwhere  
equalization of cable losses is not required.  
1. Pan/Tilt (24 VAC or 120 VAC as ordered from the  
factory)  
2. Zoom Lens — Zoom, iris, and focus with adjust-  
able speed (speed not remote controllable)  
3. Camera power (24 VAC or 120 VAC as ordered  
from the factory)  
Typically, these functions are:  
1. Pan Left  
2. Pan Right  
3. Tilt Up  
4. Tilt Down  
5. Zoom In  
6. Zoom Out  
7. Focus Near  
8. Focus Far  
9. Iris Open  
10. Iris Close  
11. Camera Power On/Off  
12. Auto/Manual Scan  
13. AUX 1 (Manual Iris)  
14. AUX 2 (Auto Iris)  
15. AUX 3  
4. An open collector transistor output (latching) in-  
tended for use in manual override of an automatic  
iris control.  
4.0 INSTALLATION  
Coaxitron System 2000 installation includes the con-  
nection of all coaxial cable to the proper connectors,  
depending on your system configuration. Various con-  
nectorassemblypin-outgeometriesareshowninFigure  
4. Connector location and pin assignments are illus-  
trated in Figure 5.  
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  
thingsaslightsorgateswithproperexternalinterfacing.  
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 simul-  
taneously with functions 1 through 10.  
For optional auxiliary functions, consult the factory to  
make the proper connections between the receiver, pan/  
tilt and camera/enclosure.

4.2 CONNECTOR ASSEMBLY  
4. The contact pins supplied with the mating con-  
nector are the “crimp” type which may also  
be soldered if you so desired (item 4).  
Installation and/or testing will require you to assemble  
the connector parts provided. Fabricate the intercon-  
necting cable according to the following steps (refer-  
ence Figure 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.  
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 con-  
nector (item 5).  
Note: Contacts cannot be removed from the con-  
nector without the use of the appropriate AMP ex-  
traction 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.  
6. Slide partAof the cable clamp toward the con-  
nector and screw the parts together.Attach part  
B (item 1) onto part A and connect both parts  
with the screws provided.  
7. Connect the cable assembly to the unit and  
seat the connector by twisting the locking col-  
lar until it snaps into position (see Figure 5  
and Figure 10).  
3. Strip back the cable jacket approximately 1-  
1/4 inches (3.2 cm) and separate the individual  
conductors (item 3).

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 transmit-  
ter, which then feeds the monitor. When a camera  
selection is made, that video line is dedicated to the  
transmitter that allows the associated Coaxitron re-  
ceiver to be controlled. Functions such as auto/random  
are latching and will remain on until turned off by the  
transmitter.  
4.3 SYSTEM CONFIGURATIONS  
Figure6showsthesimplestsystemconfigurationutiliz-  
ing the Coaxitron System 2000. This system consists of  
thecontroltransmitter, coaxcableandreceiver/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.

A more complex system is shown in Figure 8. Here,  
several control locations can serve a single camera  
system.  
This monitormayalsobeusedforsequentialswitching.  
As in the previous configuration, any one transmitter  
can assume control. If two or more control units are  
activated simultaneously, erroneous responses are pre-  
vented by error detection circuitry in the associated  
receiver.  
Note: All transmitters, except the last one, must  
be looping (unterminated) rather than terminating.  
In a system of this type, any one of the transmitters can  
assumecontrolbecausethereisnopriorityprovision. If  
two or more transmitters are activated simultaneously,  
error detection circuitry in the receiver will cause mul-  
tiple commands to be ignored.  
The switchers depicted in Figure 10 are hard contact  
devicesanddonothaveisolationorbridgingamplifiers.  
In each case, the Coaxitron transmitter acts as the  
isolation or bridging amplifier. Do not use VA500  
series switchers with Coaxitron systems.  
Figure 9 shows an even more complex system. In this  
example, multiple transmitters are controlling multiple  
receivers.  
Note: For configurations where RG59 cable  
length between the transmitter and receiver ex-  
ceeds 750 feet, it is necessary to reset switch SW1  
onthereceiverboard(PCB1500529)fromSHORT  
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.  
Note: All but the last transmitter and associated  
switcher must be looping (unterminated). Trans-  
mitters and associated switchers should be physi-  
cally 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.  
CoaxitronSystem2000basicinterconnectionsbetween  
the transmitter and receiver are shown in Figure 10. If  
you have chosen a configuration that includes a switch-  
ingdevice,refertothemanualprovidedwiththeswitcher  
for the appropriate connections.

5.0 OPERATION  
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.  
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 (momen-  
tary on-off-on).  
5.1 FUNCTIONALCIRCUITDESCRIPTION  
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  
lengthsupto750feetofRG59B/U(orequivalent),orup  
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).  
Normally, auto-target or auto-iris functions will main-  
tain a video level well within reasonable limits and  
insurereliableperformance. 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.  
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 toler-  
ated.  
The Coaxitron System 2000 is designed to combat  
prolonged loss of control due to the conditions de-  
scribed above by providing the following protective  
functions:  
Response time of the system is normally less than 30  
ms. Error detection circuitry is incorporated to immu-  
nize the system from externally generated noise. Under  
extremely adverse environmental noise conditions re-  
sponse time may increase, and in the limit, control  
functions can fail. Under such extreme conditions,  
however, provision is made to inhibit all momentary  
functions.  
1. Simultaneous commands from two different  
sourcesareprocessedtoinsurethatmanualiris  
control cannot be inadvertently selected in  
place of automatic control.  
2. Asustained(20to40second)illegalcommand  
condition results in (a) camera off,  
(b) automatic iris, or (c) manual pan.  
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 equip-  
ment 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.  
These functions greatly reduce the possibility of loss of  
control and usually eliminate the need for service.

As an example, assume that the operator switches to  
manual iris control and proceeds to open the iris exces-  
sively. The result can be a complete loss of control.  
Within20to40seconds, camerapowerisautomatically  
removed (assuming this feature exists) and auto iris is  
reinstated. Thus, distortion products are eliminated if

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. Al-  
though loop-through connections in this cable are per-  
missible, power splitter or line amplifiers cannot be  
tolerated.  
5.2 TRANSMITTER  
The transmitter is housed in a 1-3/4" high enclosure,  
suppliedasadesktopunit(rackmountavailable).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  
thesignalbyinstallingtheappropriateresistor.Connec-  
tor J7 accepts the camera signal from the receiver, and  
J6 provides an output for monitoring equipment.

Receiver Control Output for 12 VDC Camera  
Option  
Factors that limit the distance over which the Coaxitron  
can be used are transmission line attenuation and trans-  
mission line signal distortion  
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. Theoutputpinassignmentsremainthe  
same for 12 VDC camera power options, only  
now pin 9 (WH) is positive (+) and pin 14 (WH/  
YEL) is negative (-).  
When signal attenuation becomes large due to exces-  
sive cable length, the differential amplifier in the  
Coaxitron receiver can no longer detect the presence of  
acontrolpulsetrain. Thelimitationcanbeovercomeby  
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  
signalisnotrestrictedtothecablebetweenthetransmit-  
ter and receiver, but will be on all signal cables down-  
stream from the receiver.)  
Transmitter Video Input  
The transmitter usually provides for the 75 ohm  
termination of the cable from the receiver. How-  
ever, the user may alter this termination in order  
to loop through and terminate further down-  
stream. (See Figure 10.)  
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.  
WARNING: Power for enclosure models utiliz-  
ing heater/blowers cannot be tapped off the sec-  
ondary 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.  
Pre-equalization of the camera signal prior to feeding to  
theCoaxitronreceiverisgenerallynotpracticalbecause  
of the dynamic limits in the receiver video amplifier.  
Post equalization of the signal (transmitter output sig-  
nal) is permissible, but probably not practical. It should  
bekeptinmindthatalthoughthecamerasignalhasbeen  
deteriorated by the transmission line, the control signal  
has not. Therefore, the equalized control pulses will be  
extremelylargeandprobablycauseanoverloadinsome  
part of the system downstream from the equalizing  
amplifier.  
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  
betweenthetransmitterandthereceiver. The amplitude  
of ground loop potential that can be tolerated varies as  
a complex function of cable center conductor resis-  
tance, video signal amplitude, and cable length. How-  
ever, ground loop voltages that induce less than 0.5 volt  
p-pintothevideooutputofthereceivershouldnotcause  
the system to malfunction.  
In the absence of an assertive control command, the  
transmitterisinactive. Thus, itispossibletocontrolone  
receiver from more than one control.  
5.5 COAXITRON PREPOSITION  
RECEIVER  
In general, ground loop problems will seldom be en-  
countered. 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  
reducedbymorethan100timeswith200feet, andmore  
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.  
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.  
12

Up to 32 presets can be stored in each receiver. Up to 8  
presets can be activated by alarm contacts connected to  
thereceiver. Thereisalsoanopencollectoroutputfrom  
the receiver to activate an external device (such as the  
CSA764)whenthealarmcontactsareactivated. 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 se-  
quence between the alarm presets at a 5 second dwell  
time per preset.  
Thesecondpartoftheroutinewilloperatethepanleft”  
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).  
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.  
The total routine takes approximate 45 seconds to  
complete.  
5.5.1 Power-up Routine  
5.5.2 Creating Presets  
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.  
At the present time the only Coaxitron system transmit-  
ters capable of creating presets are the CM7500, the  
CM9500MatrixandtheMPT9500.Refertotheinstruc-  
tions in the product manuals (C584M, dated 2/90 or

5.6 AUXILIARY FUNCTIONS  
examples of typical circuits used for auxiliary func-  
tions.  
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.

5.7 AUTO/RANDOM OPERATION  
2. Insert spacers into appropriate holes in the  
motherboard and snap firmly into place.  
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  
betweenabout4 secondsandaprogrammable60to900  
seconds. At the completion of a dwell period, another  
randomscanperiodisstarted. Thedirectionofthisscan  
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 approxi-  
mately 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 half-  
hour timer. Similarly, commanding AUTO while in  
AutomodecausesashifttotheRandommodeandzeros  
the half-hour timer.  
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  
permitslocaloperationofallfunctionsdirectlyfromthe  
receiver unit, and also serves to verify that the receiver  
and accessories are operating properly by providing  
visual confirmation. This module also aids in trouble-  
shooting receiver or transmitter operational problems.

7.0 MAINTENANCE  
6.0 TROUBLESHOOTING GUIDELINES  
The Coaxitron System 2000 is engineered to provide  
years of reliable service. The Coaxitron System 2000  
has very few operator serviceable parts and we recom-  
mend that system components be serviced by a trained  
technician or returned to the factory for repair.  
If you experience operating problems with either the  
receiver or transmitter, first check all fuses and voltage
