PTX Universal PanTiltheads provide a new dimension of production functionality and versatility. Using VISCA and DMX controllers with your favorite camera or camcorder, PTX gives you the ability to remotely control most camera operations, including pan, tilt, zoom, iris and focus, using a joystick and various hardware and software interfaces.
The chassis support the following connections and protocols:
Use the DOWN • UP • ENTER buttons to select the DMX fixture ID number.
The PTX fixture uses standard DMX 3-pin XLR cable connectivity protocol, and supports IN/OUT daisy chaining on a universe with other DMX fixtures.
The pictures on the right show the custom breakout cable from the Micro Studio Camera 4K with terminations for external LANC communications and DC power for the camera body … and the RS232 connection to the AJA RovoCam.
There are dozens of DMX lighting consoles and inexpensive DMX software controller systems available. Many include USB to DMX hardware cables or devices.
RUSHWORKS VDESK, and REMO … the ruggedized remote portable configuration … includeTHREE powerful and versatile user interfaces, and communicate with most serial or IP controlled PTZ cameras. But if you’d like to use your favorite camera or camcorder with the system, the PTX makes it possible. You can configure any combination of up to 12 PTZ cameras, PTX fixtures, and manned cameras that output SD/HD-SDI or HDMI. Use the included joystick to frame shots for named and saved presets.
Here is the 14 channel DMX control profile for the PTX Universal PanTilt heads.The first six channels control Pan, Tilt, Speed and Reset values. Channels 7 - 14 are unique to the PTX, translating DMX values into LANC, values that are sent via the internal cables to the camera.There are other profiles used when controlling Panasonic REMOTE cameras, as well as ‘block’ cameras using VISCA protocol.
Ctrl+R is the camera control utility embedded in VDESK and REMO, but also available as a standalone app for use on Windows OS devices. Use this app to add sophisticated camera control for production systems like the Blackmagic ATEM, NewTek TriCaster and others, as well as with dedicated hardware switchers from Panasonic, Grass Valley, Ross, Roland, Datavideo and many more.
Blackmagic ATEM Software
The PTX isn’t controlled directly from the ATEM software at this point, but that is being considered by Blackmagic Design. But VDESK/REMO and Ctrl+R use LANC protocol to communicate with the Micro Studio Camera 4K via the multi-pin breakout connector on the the side of the camera. This connector will also provide RS422 communications to the PTX if enhanced controls are added by Blackmagic in the future.
Use the six MODE SWX DIP settings to identify the controller setting and camera settings. If SW 1 is OFF (DMX controller mode) then the rest of the switch settings are ignored.If SW 1 is ON (VISCA), then set SW 2 according to your camera/lens device. ON routes VISCA control to your camera; OFF sends LANC and Panasonic remote commands to the camera. SWX 3-5 set the serial communication protocol to your camera.
The PTX head provides DC power to the camera you select. Each head includes a small “tweaker” for setting the voltage from 3V to 28V. There is a built-in three-digit voltage meter for monitoring the voltage as you trim the adjustment.There is a small hole on the side for accessing the voltage adjustment pot.
In addition to pan and tilt, the PTX fixtures provide control of zoom, focus, iris, and record start/stop for many LANC and Panasonic cameras, as well as full VISCA CCU control of cameras like the AJA RovoCam that support the full VISCA command set.

The internal wiring allows 360° rotation and 90° tilt (60° tilt on Model 1) without straining the cables. The SDI In is used specifically with the Blackmagic Micro Studio Camera 4K, connecting the SDI out of an ATEM switcher to the camera for software control. For cameras that support genlock the SDI IN connector can be used for that signal. The SDI Out comes from the BNC connection on a camcorder.
The PTX Model 1 is designed to work with smaller cameras like the AJA RovoCam, Blackmagic Design Micro Studio Camera 4K, Canon XA35 and other standalone cameras and camcorders of similar size that support VISCA, LANC and analog remote protocol.
The PTX Model 2 uses the same universal support protocol, but accommodates heavier and wider cameras like the Blackmagic Ursa Mini, RED, ARRI, larger field production cameras, and DSLR-style camera bodies.
This VISCA controller has been around for decades, and can be used effectively with the PTX heads. Daisy-chain up to seven fixtures using the 422 connector on the controller and the same connector on the heads. Non-VISCA cameras will use LANC or Panasonic commands translated from VISCA, and output to the cameras on the wires in the PTX cable bundle.

Because the PTX supports full DMX control,they can be added as a fixture profile in lighting consoles and software, allowing the lighting designer to program scenes which include both lighting and video presets.
