the BCD output function, Cruc Src 1 BCD or Cruc Src 2 BCD.
All three outputs will be inactive for position 1, all three outputs will be
active for position 8. The first output in the sequence is the LSB.
Eight consecutive relay or TTL outputs must be available when selecting
the Bin output function, Cruc Src 1 Bin or Cruc Src 2 Bin. In BIN mode,
