The Command Deck Unit is used initially to program the acoustic identity of the transponder, test the transponder and, in the case of the LRT, load the release ‘bit’ prior to deployment. Once deployed, it can be used to measure ranges to the transponder and prior to sending a secure release command, relocate the transponder. The command deck unit can also be controlled via RS232 enabling raw range data to be logged to a PC. The system comprises a command deck unit and dunking transducer supplied with 10 m of cable.
