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