Bx Operating Mode
This operating mode provides differential corrections obtained by the
internal beacon receiver of the GBX, to a separate GPS receiver. The
output in this mode of operation is differential correction information in
the RTCM data format.
To establish communications between the GBX and an external GPS
receiver when in Bx mode, you must:
•
Connect Pin-2-TXA of the GBX to the receive pin of the GPS receiver
•
Connect Pin-5-Common Ground of the GBX to the signal return or common
ground of the monitor.
