Datasheet OBC/LRT Deck Unit
Description Part of Sonardyne's Coastal Acoustic Product Range, the Type 7967 OBC/LRT Deck Unit is used to command and programme Sonardyne's range of TZ/OBC transponders and Lightweight Release Transponders (LRTs). It comprises of a deck unit and dunking transducer supplied with 10 metres of cable. Key features * Supplied in rugged, portable case * For use with Type 7815 TZ/OBC Transponders and Type 7986 Lightweight Release Transponders * Enables transponders to be tested and programmed with thousands of unique identities prior to deployment * Highly secure coding sequence prior to commanding LRTs to 'release' * Powered by alkaline battery packs; supplied with 2 spare packs * Easy to operate
The 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 deck unit can also be controlled via RS232 enabling raw range data to be logged to a PC for processing.
