Upon detection of its ARM code, AR8x1 unit transmits an acknowledgement pulse (CAF). TT801 detects CAF pulse and the distance in meters between TT801 and AR8x1. TT801 transmits the ‘Release+Pinger’ code. Upon receipt of this command, the AR8x1 replies in turn by sending a second CAF pulse, which is also used to measure again the distance.

Remote Control System TT801 – User Guide II.4 General Recommendations Prior to any operational use in the field, a complete functional checkout of TT801 Deck set and battery charge should be made. Whenever it is possible, it is recommended to operate the TT801 cabinet from internal battery pack with no connection with the AC Mains.
For the 24 VDC power supply input, connect the 24VDC power supply cord to the SOURIAU 6 way socket (see Figure 7). Acoustic The TT801 unit comes with a standard dunking transducer (PET 801 P-30) fitted with transducer 30m-long cable. Connect the dunking transducer cable to the ‘XDC’ front panel receptacle.
