F175 MOTION Sensor - Trimble SPS361/SPS461 Integration
2 Connection Details
The F175 System should be connected to the Trimble SPS361/SPS461 using one of the RS232
serial ports. On the F175 System the “External GNSS” connector is used. On the Trimble
SPS361/SPS461 receiver any of the serial ports can be used.
The Trimble SPS361/SPS461 are supplied with a combined power/ethernet/serial cable. The 9-
way connector on this cable is suitable for connecting the Trimble SPS361/SPS461 to a
standard 9-way serial port on a PC. However a RS232 NULL Modem connector is require to
connect the Trimble SPS361/SPS461 to the F175 System.
Power to the GPS receiver and power to the F175 System are wired separately to each
product. A common ground should be used to avoid ground problems.
