Notes on Auxiliary Commands Data

Setting both the DisKB and EnKB will cause a command error.

One, and only one of the RSP, RTS, and RPS bits must be set when transmitting this

command. Setting more than one, or none, will cause a command error.

Preset Position Data

When the Preset Position bit, (bit 11) of the Command Word is set, the 2762-17 presets the

position of one or both of the transducers. This is accomplished by calculating the internal

offset needed to change the transducer position to the preset value programmed with the

transducer setup data.

Words 1 through 11 are not used, but must be transmitted. These words should be

considered reserved for future use and must be set to zero. The data format for Preset Position

is show in figure 6.5
