The PTX Model 2 Internal Wiring Bundle
To minimize torsional stress on wires and connectors in a
housing that can spin 360°, the wires run through the
core of the PTX chassis and pan/tilt yoke.
The BNC connections (IN and OUT) on the base of the
Model 2 are connected internally to the two BNC
connections on the rotating arm of the Model 2. The only
wire emerging from the top of the tilt assembly is a Micro
HDMI connector. If your camera outputs SDI, you’ll
connect the camera out to the IN BNC on the arm.
The SDI Out from the camera is then available on the full
size BNC connector on the PTX chassis.
If the camera provides an HDMI output, the connector is
available on the base, below the VISCA RS422 Phoenix
connector.
Note: If your camera requires a GENLOCK source, use the SDI IN on the chassis for that
signal, and run a short BNC cable from the OUT on the Model 2 arm for connection with the
Genlock In on your camera.
DMX Control: If you’re using more than one PTX head,
connect the DMX OUT to the DMX IN of each fixture
(daisy-chain) for control.
VISCA Control: Daisy-chain up to SEVEN PTX heads by
connecting the RS422 OUT from the first to the RS422 IN
of additional fixtures. THE DMX ID (LED) MUST BE SET
TO CHANNEL 1 ON ALL SEVEN FIXTURES!
The DMX/VISCA ID (DIP switch) must be set to 1 – 7
on the respective fixtures.
The PTX PanTilt heads are designed to integrate
seamlessly into any DMX hardware or software controlled
system.
Set the DMX ID for each fixture as you would with any
other DMX lighting fixture. When you turn on the power
switch, the system will initialize, displaying head
information, then turn off.
