The CTG Marine Deck Unit interfaces between the computer and the instruments. It supplies the power to the instrument suite and converts the RS422 output from the instruments to the RS232 format required by the PC. The CTG Marine Deck Unit case may be rack mounted or stand alone by removing the mounting lugs. The case is not spray proof so it must be sited within a deck house environment. Having a 72 VDC output it is specifically designed with sufficient voltage overhead to operate on most multi-core oceanographic cables up to 1000 metres long when providing 1A to the sub-sea instrumentation.The CTG Marine Deck Unit is typically used in real time deployments of towed vehicle based systems, ie, Nn-Shuttle and AQUAshuttle III and profiling packages. However it can also be used in the laboratory during sensor calibrations etc. The appropriate interface unit to instrument cable is required. |
The CTG Marine Deck Unit can be supplied in a 19" cabinet. This cabinet, 17U high, can accommodate a 4U high CPU fitted with three additional serial ports. A 15" TFT LCD colour monitor (7U high) and keyboard with an integrated tracker ball (1U high) completes the system. There is a spare 3U high slot should an additional piece of equipment need to be added at a later date.

Description: |
|
|
The Portable Interface Unit converts the RS422 communications protocol of the subsea instruments (required to enable communications over long cables) to RS232 for interfacing to a host PC running AQUAsoft. Having a low voltage output (16VDC) the PIU is not designed to withstand large voltage drops experienced when deploying instruments on long cables. It is used with short cable lengths (typically 3m). |
A mains powered adapter (110-240 VAC) allows recharging of the internal battery whilst simultaneously powering the instrument. The appropriate interface unit to instrument cable is required. This unit is not designed to provide power during deployment. |
