Transducer Setup Read Back Data
When you send an Auxiliary Commands command with the RTS (Read Transducer Setup)
bit set, the 2762-17 responds by echoing back the Transducer Setup data. The Channel
Number bit (bit 00) of the Auxiliary Commands command determines which transducer data is
set. Therefore it requires two BTW/BTR sequences to read all of the Transducer Setup data.
The format of the data is shown below in figure 6.7. Note that read back data has bit 15 of
word 0 set to '1'.
