The RCU consists of two main parts, The surface unit and the Subsea unit. The surface unit consists of a laptop PC with a RS232-485 convertor providing communication interface to the subsea unit. The PC comes pre-installed software for controlling the Subsea unit. The Subsea valve module is capable of setting two different pressures, This allows separate pressure to the latch cylinders verses the torque motor on the API 17D Class 1-4 Torque Tool.
