Baxall Telemetry
The ZTX3 and ZTX4 are both Baxall telemetry transmitters, this means that they
transmit telemetry for reception by a Baxall receiver such as the ZR3-mini or
ZR4-mini. Baxall telemetry is for operating a pan and tilt head (P/T head), a lens and
auxiliaries by remote control. It comes in two main formats, coaxial and twisted-pair.
Figure 1 below shows a typical layout for twisted pair telemetry. Twisted pair
telemetry (ZTX4 only) is transmitted on separate wires from the video signal. This is
useful for compatibility with free-space transmission systems which are generally not
compatible with coaxial telemetry.
Baxall coaxial telemetry communicates down the same coaxial cable as the video
signal. This has the advantage of only requiring one connection between the camera
position and transmitter.
Baxall coaxial telemetry comes in two types referred to as old and new. The old
coaxial telemetry is asynchronous (not synchronised to the video signal) and can
sometimes interfere with on-screen displays (O.S.Ds) such as those produced by
multiplexers or time and date generators. To remedy this new coaxial telemetry is
synchronised to the video signal.
You can switch your ZTX between old and new coaxial telemetry via a switch on a
back panel (see figure 2). Unfortunately, new coaxial transmission only works with
recent Baxall receivers such as the ZR3-mini and ZR4-mini. Your ZTX is set to old
style telemetry as a default.
The ZTX3
The ZTX3 has 10 keys, a monitor output BNC, a camera input (telemetry output)
BNC, a supplementary earth terminal and a row of switches.
The ZTX3 transmits coaxial telemetry. It can control pan, tilt, focus, zoom, and two
latching auxiliaries AUX1 (camera power) and AUX3 (auto-pan). The switches on the
back panel allow selection of old or new coaxial telemetry and 75 ohm or Hi-Z
options on the camera input. You can use the Hi-Z option if you use a T-piece to
connect the camera input to another 75 ohm terminated load, such as a monitor or a
VCR.

Page 4
The ZTX4
The ZTX4 has 15 keys, a monitor output BNC, a camera input (telemetry output)
BNC, a 6-pin-mini-din 20mA-twisted-pair connector, a supplementary earth terminal
and a row of switches.
The ZTX4 can transmit coaxial or twisted pair telemetry. It can control pan, tilt, focus,
iris, zoom, four latching auxiliaries AUX1 (Camera power), AUX3 (Auto-pan),
AUX5 (Lamps), AUX6 (Wipe) and one momentary auxiliary AUX2 (Wash).
The switches on the back panel allow selection of old or new coaxial telemetry and 75
ohm or Hi-Z options on the camera input.
The twisted pair connector is a 6-way mini-din socket which carries the current loop
output plus an optional link which when made changes the baud rate (speed at which
the data is transmitted) from 1200 baud to 300 baud. The slower rate of 300 baud is
included to improve reception in electrically noisy environments such as near an
electrified railway track.
Fitting the 6-pin mini-din plug with pin 3 linked to pin 1 automatically disables the
coaxial telemetry and enables 20mA twisted pair telemetry.
Associated Equipment
Your ZTX can be used in many different configurations. A basic system is shown in
figure 1, this basic system includes:
•a monitor
•a VCR
•a ZTX transmitter
•a Baxall telemetry receiver (e.g. a ZR4-mini)
•a P/T head
•a CCTV camera (e.g. a Baxall CD9312 colour camera)
•a motorised lens
•BNC connectors
•coaxial cable
•twisted pair cable
•associated wiring
Figure 1 shows a system using twisted pair telemetry. A similar system using coaxial
telemetry would be the same but have all the twisted pair connections removed.

Connection
Standard Connection
Connect a 75 ohm video coaxial cable terminated with BNC connectors from your
ZTX to your monitor
Connect a 75 ohm video coaxial cable terminated with BNC connectors from your
ZTX to your receiver (see the receiver instructions.)
The default termination for the camera input is 75 ohm. If you want to use the same
video signal for another piece of equipment, connect a T-piece to the camera input,
de-terminate the input using the switch on the rear panel (select Hi-Z, see figure 2)
and ensure that the coaxial cable is 75 ohm terminated somewhere else (e.g. in your
VCR or extra monitor).
The switch setting for old and new style coaxial telemetry is also shown on figure 2.
Twisted Pair Connection, ZTX4 only
Wire up a 6-pin mini-din plug according to figure 3.
Link pins 3 (enable) and 1 (GND) to enable twisted-pair telemetry (and automatically
disable coaxial telemetry).
The default baud rate is 1200 baud. Connect pin 6 (300 baud) to pin 1 (GND) if you
want to use 300 baud.
Connect the plug to the twisted pair connector and connect the other end to your
receiver (see your receiver instructions).

Operating
The ZTX4 key board is shown in figure 4 along with an explanation of the key
functions. (The ZTX3 is similar but has fewer keys)
The symbols for the auxiliaries are equivalent to older Baxall auxiliaries as follows:-
Equivalent Symbol AUX number

Lamps AUX 5

Trouble Shooting
Controls Reversed : If left and right, etc. are reversed on your ZTX, this is usually
due to incorrect receiver wiring, see the receiver instructions.
Picture Tearing : If the picture ‘tears’ at the top when you use a caption generator or
multiplexer with built in caption generator. This may be caused by the old style
coaxial telemetry. If you have a ZR-mini or more recent receiver then changing to the
new style telemetry may remedy this. This places the telemetry information in the
blanking period of the video signal instead of continuously across the whole frame.
