CV-PT-HEAD
Instructions
The
CV-PT-HEAD
(µL) can be controlled by CV-MICRO-JYSTK or any BR Remote style
controller. These controllers generate RS485 data which can be connected directly to the CV-
PT-HEAD or sent via an IP network with IP adaptors. The RS485 data can be sent up to
3,000+ feet (1km) on a four (4) pin XLR cable.
Power for the µL can be up to 35V so cable length can be extended very long ranges by
increasing the voltage to the CV-MICRO-JYSTK remote end.
Inside the unit is a 12v
regulated supply for the camera so it does not matter what voltage you send to the CV-
MICRO-JYSTK, the camera will always be provided 12V power.
Both power and RS485 control data are delivered via 4pin Lemo connector on the base. Then
the Lemo (base) to Hirose (camera) cable is used to provide command and power to camera.
Marshall cameras use (VISCA) commands to adjust settings in the camera. The control
protocols for these cameras are embedded in the CV-PT-HEAD and can be connected to the
camera with included patch cable. The camera itself can then be controlled via BR Remote
controllers. The Camera CCU output is RS422 and is on the 7pin Lemo connector passed
through to camera with Lemo to Hirose cable.
The CV-PT-HEAD is IP65 weatherproof and can be used outside. This makes a perfect
match for the Marshall CV503-WP IP67 weatherproof camera model for outdoor or dirty
environment use.
There are slipping clutches on both pan and tilt motors which
prevent damage to the mechanics if it is moved inadvertently
during rigging or if it hits an obstruction during movement.
Need to hang it upside down – no problem. There are 3x M4
mounting threads as well as a ¼"-20 on the base of the PT
Head. Simply flip the image in the Marshall Camera OSD Menu.

- Page 1 CV-PT-HEAD Instructions CV-PT-HEAD (µL) can be controlled by CV-MICRO-JYSTK or any BR Remote style controller. These controllers generate RS485 data which can be connected directly to the CV- PT-HEAD or sent via an IP network with IP adaptors. The RS485 data can be sent up to 3,000+ feet (1km) on a four (4) pin XLR cable.
- Page 2 Joystick Control The CV-PT-HEAD contains 10 gears. Some controllers can select any gear, but others can only select a fewer number of gears. The movement is fully proportional to the joystick displacement in all gears. If the ‘turbo’ button is enabled on the controller this will set the speed to the fastest gear triggered by holding down the button.
- Page 3 Cable Management On the pan cover, under the camera plate are two M2.5 threaded holes. These can be used to attach cable management clips if required. Pan & Tilt Clutch Adjustment Both the pan and the tilt clutches can be adjusted if needed. To adjust the pan clutch, remove the Pan Cover which is secured with a single screw.
- Page 4 Safety There are 2 M4 bolts fitted to the base which should be used for a safety bond if the unit is rigged above head height. Also, on the base is a standard ¼”-20 camera mounting thread and 3x M4 threads. Any of these can be used for mounting the unit to a suitable platform.
- Page 5 Camera Specific Connections CV-PT-HEAD comes with a Lemo (base) to Hirose (camera) cable for Marshall cameras. The table below is used if a Male connector is fitted on the camera. ie. if the connector on the camera itself has pins – like in the picture.
