The GPS serial output connects to the IMU box. Use the GPS system's own serial cable to
connect the GPS to the DB-9 serial port on the IMU box. On the other side of the IMU box,
connect the IMU cable to the round connector. The IMU cable is reversible so it does not
matter which side is connected to the electronics box and which side is connected to the IMU
box. The dust cap is used to protect the connectors during shipment and storage, but please
remove these and place them away from the sensors during operation.

The electronics box is connected to the field tablet computer via the ruggedized Ethernet cable.
The Ethernet cable plugs into the top of the field tablet and the side of the electronics box. In
the event the cable is damaged, any Cat 6A or Cat 7 Ethernet cable with RJ45 connectors can be
used as a replacement. Note that Cat5e or lower will not work with the instrument as the
throughput is not high enough.
