Troubleshooting     C

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 receiver’s 
external power source is charged and 
that power output on Port 3 is 
enabled.
