Troubleshooting C
Trimble R7 and R8
Reference receiver is
not broadcasting.
Port settings between
reference receiver and radio
are incorrect.
Using Trimble Survey Controller,
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 receiverās
external power source is charged and
that power output on Port 3 is
enabled.
