The U6 HD Remote Head is mechanically and electronically identical to the U5 but is 100mm taller. It is therefore more suitable for under-slung operations where the camera is required to tilt vertically downwards.
The mechanics are very precise with extremely low backlash. Clutches are fitted on both axis to aid rigging and protect the servo gearboxes from damage. The tilt clutch is externally adjustable to aid camera balancing and has a hollow shaft to allow cable routing. The unit can be C or G balanced for perfect control. The unique servo drivers achieve speeds of up to 150 degrees/sec yet still deliver smooth moves at the tight end of the lens.
Data is sent using RS485 which allows ranges of over 1km on twisted pair cable. For camera control this is converted to the appropriate camera protocol inside the head for communication with the camera. This can be RS232, RS485, LANC or many other standards.Up to 10 heads can be ‘daisy-chained’ on the same data cable and up to 64 heads can be supported on a system.
Various camera and lens protocols can be programmed into the U5-HD enabling full remote control over the single serial data link. A 12v @ 3A camera PSU is also built into the unit. Two 12 pin Hirose lens control sockets are fitted on the front of the camera support saddle and a 9pin and 15pin D plug are fitted on the rear.
This arrangement ensures that the camera and lens cables do not interfere with the movement. A tally light is fitted to the front with additional outputs on the rear. There is also provision for LANC control via the 9pin D socket. Internal drivers are provided for digital lens control and can be routed to the lens control sockets.
Up to 32 preset positions can be stored and recalled. Each position includes, Pan, Tilt, Zoom and Focus positions. Once stored, the positions are saved during power off and are not lost even if the head is moved using the slipping clutches. Pan and tilt limits can also be set by the user.
1. Passing a cable through the hollow shaft in the clutch side.
A hollow shaft is provided for routing cables to the camera if required. For applications which do not require continuous 360deg. pans this is a simple option.
2. Using HD component outputs and converting after the slip rings.
Many cameras have an HD component output which can be passed through the slip rings. Bradley Engineering has produced a miniature SDI / HDSDI converter which can be built into the base after the slip rings. Our CamBall HD uses this technology and the converter is also available as a miniature stand-alone unit.
Start and remote stop for all the cameras, but not for the cameras that need their own cable of sufficient length. Two composite video cables and a triax cable, take the video signals from the camera to the control station.
