Outputting DGPS corrections to another source
SC-104 OUT outputs differential corrections from your 961XD’s internal
differential receiver to an external device that accepts the standard
SC-104 data stream. When using the SC-104 OUT setting, be sure that the
BAUD setting also matches the baud rate requirements of the receiving
device.

option is for factory diagnosis of 961 operating

Port off
Use the OFF setting when the aux port’s input or output functions aren’t
needed.

rate
