Trimble R7/R8 GPS Receiver Operation
Reference receiver is
not broadcasting.
Port settings between
reference receiver and radio
are incorrect.
Using the Trimble Survey Controller
software, connect to the reference
radio through the receiver. If no
connection is made, connect directly
to the radio and change the port
settings. Try to connect through the
receiver again to ensure that they are
communicating.
Faulty cable between receiver
and radio.
Try a different cable.
Examine the ports for missing pins.
Use a multimeter to check pinouts.
No power to radio. If the radio has its own power supply,
check the charge and connections.
If power is routed through the
receiver, ensure that the receiver’s
external power source is charged and
that power output on Port 3 is
enabled.
