The MPT9000 Series offers a versatile transmitter/controller that
can be used in a variety of applications for controlling pan/tilts and
cameras.
The desktop or rack mount units have an eight-position joystick for
operating pan/tilts, and switches for control of camera zoom, focus,
and iris functions. There also are switches for auxiliary functions to
control such things as lights or doors. The transmitter/controller is
compatible with random interlace and 2:1 interlace cameras.
The MPT9000 Series is capable of auto/random scan operation
when used with an appropriate receiver, such as the IRD2024 or
ERD2200.
The MPT9000 Series uses Pelco’s Coaxitron
®
system to send
control signals to pan/tilt receivers. Coaxitron allows control signals
to be sent over the video coaxial cable, eliminating the need for
separate control wiring between a transmitter and receiver. The
control pulses are superimposed upon the video signal during the
vertical blanking interval where they are not noticeable on the
monitor.
The MPT9000 Series can be used in short or medium distance
applications when equalization of cable losses is not required. For
longer distances an equalization amplifier (EA2000) can be used.

SYSTEM OVERVIEW
BASIC COAXITRON SYSTEM
In the simplest form, the Coaxitron system consists of the control/transmitter, coaxial cable, and receiver. Up to 16 separate functions (up to
10 simultaneously are transmitted over the coaxial cable to the remotely located receiver.
These signals are then converted to drive voltages or relay switching for the appropriate accessory equipment being controlled.
The basic Coaxitron is extremely flexible in that it can be expanded to control multiple camera sites with the addition of certain switching devices
such as Pelco manual switchers, non-amplified bridging sequential switchers, VS5004/VS5008 sequential switchers, and Coaxitron matrix
switching systems.
MULTIPLE CAMERA COAXITRON SYSTEM
The multiple camera Coaxitron system is an expansion of the basic Coaxitron system. In this example, a manual video switcher has been added. 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, which allows the associated Coaxitron receiver to be controlled.
Functions such as auto/random scan are latching and will remain on until turned off by the transmitter.
MULTIPLE CONTROL STATION COAXITRON SYSTEM
In the absence of an assertive control command, the transmitter is inactive. This allows several transmitters to control one receiver. If two
transmitters are activated simultaneously, more than the allowable number of pulses will be detected by the receiver and the simultaneous
commands will be ignored.
The video cable from the receiver is looped through the Coaxitron transmitters and is terminated at the final control station.
MULTIPLE CONTROL STATIONS AND CAMERAS
This system represents the most sophisticated of the Coaxitron systems. In this particular example multiple transmitters control multiple receivers.
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 is used. The monitor 2 output is a hard contact switch, otherwise known as the bridged output, for continuous viewing or
control selection. This monitor may also be used for sequential viewing.
In multi-control, multi-receiver systems, any one control can assume control inasmuch as there is no priority provision. If two or more control units
are activated simultaneously, erroneous responses are prevented by error detection circuitry in the associated receiver. Any control may assume
control of any receiver at any time.
