Trimble Standard Interface Protocol

The bits are numbered in descending order of receipt, starting with bit 31 as the MSB of Byte 1, down to bit 0 as the LSB of Byte 4. A "0" in the bit position disables automatic output of the associated packets; a "1" in the bit position makes the associated packets available for automatic output. Table A-77 describes the packets affected by each bit.
