DECLARATIONS
The manufacturer declares that the DAX unit supplied with this manual is compliant with the EMC directive 89/336 EEC and the low
voltage directive 73/23/EEC and 93/68/EEC.
DESCRIPTION
The DAX/VCL converts Baxall coaxial telemetry into Dome telemetry. It connects between your transmitter and dome camera in the
coaxial line as shown below. The DAX/VCL requires a +12 VDC or 24 VAC class 2 isolated power supply.
We do not recommend the use of the DAX range with fixed speed telemetry controllers. Best operation is achieved with the Baxall
ZKX2/J, ZKX3/J or Vista NPX/RKB/J keyboard used with a ZTX6, ZMXplus, Vista Gen3 or Vista Columbus unit.
Note: Baxall Limited have tested and validated correct operation
with cable lengths between the DAX unit and dome of 10 metres.
For distances greater than 10 metres, the installer is advised to
undertake a site trial to ensure satisfactory operation.

SWITCH SETTINGS
The DAX/VCL is compatible with the VCL manufactured Orbiter, Orbiter Lite and Jupiter models of dome camera. One DAX/VCL is
required for each VCL dome camera installed—this product does not support daisy chain networks.
The DAX/VCL supports the programming and recall of up to 16 presets and 4 tours. It also supports auto-iris, auto-focus and
colour to monochrome switching functions, where available (Orbiter model only). These functions are enabled or disabled using
a bank of DIP switches on the end panel of the DAX/VCL, as described below:

STORING AND RECALLING TOURS
Storing a Tour
Before programming and storing a tour, set the tour seek speed and tour dwell time using switches 4 and 5. For example to store
a tour with 100O per second seek and a 4 second dwell time, the switches must be set in the following positions prior to
programming:
• Set switch 4 to the ON position = Tour seek speed of 100O per second.
• Set switch 5 to the OFF position = 4 second dwell time at each tour position.
A tour can then be programmed and stored by following the procedure below:

EXTENDED FEATURES
Auto-Focus Timer
When the auto-focus timer is enabled, the operator can still focus the dome camera manually using the Focus Near ( ) and
Focus Far ( ) keys on a transmitter. However, 20 seconds after the last focus key press, the dome camera will perform an
auto-focus operation. When the auto-focus timer is disabled, all focus adjustments have to be made manually using the Focus
Near ( ) and Focus Far ( ) keys on a transmitter.
Auto-Iris Timer
When the auto-iris timer is enabled, the operator can still adjust the iris on the dome camera manually using the Open Iris ( )
and Close Iris ( ) keys on a transmitter. However, 20 seconds after the last iris key press, the dome camera will perform an
auto-iris operation. When the auto-iris timer is disabled, all iris adjustments have to be made manually using the Open Iris
( ) and Close Iris ( ) keys on a transmitter.
Automatic Colour/Mono Switching

If switch 8 is turned ON, the effect of pressing the Autopan (
the dome pans left for 20 seconds and then right for 20 seconds. This left/right movement will repeat until autopan mode is
deactivated. To do this, press the Autopan (
) key again or enter a telemetry command (i.e., move the joystick).
If switch 8 is turned OFF, the effect of pressing the Autopan (
) key is that the last-used tour is recalled.
180O Pan Flip
To make the dome camera perform a 180O horizontal pan rotation (or ‘pan flip’), press the Wash (
) key.
INSTALLATION
All video is 1V pk-pk composite via 75 ohm video coaxial cable and BNC connectors. The connections to your DAX/VCL are shown
on the case and in the schematic overleaf.
• Connect the +12 VDC power supply and the Dome Cameras’ RS485 extension lead to the connectors on the DAX/VCL according
to the schematic diagram on page 1.
• Connect the DAX/VCL to your transmitter and to your dome camera according to the schematic.
• Since the DAX/VCL has internal termination, ensure that the dome camera is terminated i.e. termination ON.
• Set the camera address to 1 (see your dome camera instructions for more details).
