RS-485 / RS-232 Pan and Tilts

Rugged pan and tilts with RS-485 / RS-232 computer control to remotely orient camera systems, acoustic equipment, RF and microwave antennas, and other instrumentation.

The unparalleled reliability of the PT-10-FB RS-485 / RS-232 computer controlled pan and tilts is due in part to its rugged construction. Housings and machined components are made of corrosion resistant, hard-anodized aluminum. All external hardware is made of stainless steel for deep water or hazardous environment applications.

The PT-10-FB RS-485 / RS-232 computer controlled pan and tilts provides 10 lb-ft (13.56 N-m) of output torque on each axis. Heavy-duty ball bearings supporting the output shaft allow it to accommodate payloads up to 25 lbs (11.3 kg). Each axis of the pan and tilt includes a DC brushless stepper motor coupled to low backlash harmonic gearing. It is designed to allow stalling of the output shafts without damage to the gears, the motors, or control electronics.

The RS-485 / RS-232 computer control enables the pan and tilts to be highly configurable and precision controllable. By using either the ROS positioner GUI (graphical user interface) or the ROS communication protocol for custom software integration you can control unique features such as: variable rotation speed, real-time position feedback, variable braking, programmable software limits, and networkability of multiple ROS RS-485 / RS-232 pan and tilts sharing the same cable. A total of only four wires (two for power; two for communication) are needed to operate the RS-485 / RS-232 pan and tilts.

Using RS-485 control provides several advantages over RS-232. RS-485 allows communication over longer lengths of cable (1000 feet) and enables the ability for networking multiple nodes. A typical computer has the capability of RS-232 communication through its serial COM ports. Inexpensive devices are readily available for converting RS232 to RS485, USB to RS485, or Ethernet to RS485. This unit may also be controlled by an external joystick.

The PT-10-FB RS-485 / RS-232 computer controlled pan and tilts are available in two versions: air-filled or oil-filled. Air-filled pan and tilts are used for shallow water applications up to 30 meters depth. Also, air-filled pan and tilt units are suitable for above water applications where rain, humidity, and dust are issues. Oil-filled pan and tilt units are used for deep water applications up to 3,000 meters depth.

The PT-10-FB RS-485 / RS-232 computer controlled pan and tilt complement all ROS underwater lights and underwater video cameras.
