The deck unit is used initially
to program the acoustic identity of the transponder, test
the transponder and, in the case of the LRT (Lightweight
Release Transponder), 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 deck unit can also be controlled via
RS232 enabling raw range data to be logged to a PC.
