Note: Baud rate selection for the four DPP channels is made at the four rotary switches (S4, S5, S6,
and S7) on the front of the circuit pack. The baud rate selected can be set for synchronous or
asynchronous operation at S2 and S3. The chart shows conversion for asynchronous to
synchronous baud rates and rotary switch position for the applicable selection.
