2.
For 900 MHz modules running the Easy IP protocol, is the radio name set 
correctly? Use the procedure in 3.3 Configure radio, page 20, to make sure that 
the name does not contain spaces? If the current name contains spaces, enter a 
correctly formed name.
3.
Use CSG Test Suite to check the reliability of the CMR reception.
Note – CSG Test Suite can be downloaded from the Trimble web site. Navigate 
to Support & Training|Support > Support A-Z > SiteNet™ 900 > Downloads. 
Install the software on the same computer that you run WinFlash on, and use 
the same service cable to connect to the radio.
Reception integrity should be greater than 90%. If reception integrity is lower 
than 90% suspect a damaged antenna. If the antenna is known to be good, 
suspect a failed radio. Swap in a known good radio, and retest. If integrity is 
still low, suspect a problem with the base station or with the radio network 
setup. For example, is the rover within line of sight of the base or repeater?

Base radio troubleshooting
It is beyond the scope of this manual to give detailed instructions on troubleshooting 
GPS base station and/or wireless network access point problems. For detailed 
troubleshooting information, refer to the documentation supplied with your base 
station radio. In general, you should check these items when troubleshooting:
Are all the devices on the system receiving power?
Are all the radios in the system communicating?
Are all cable connections secure and undamaged?
If the base radio is a Trimble SNB900 radio modem, observe the following points:
1.
Check the connection between the base GPS receiver and the SNB900 Lemo 
port.
2.
For SNB900 base stations that are also network access points for wireless data 
networks (referred to as co-located bases), check the connection between the 
LAN and the SNB900 modem port
3.
Check the SNB900 settings by observing the front panel. The following should 
be displayed on the front panel during proper operation:
Note – You must scroll down to view some items. Also, some items are 
alternated with others on the display, so observe the display for a few seconds 
to make sure you view all alternate items.
Easy IP – Easy IP protocol selected for two way data networks
Sync alternating with one or both of Trans and/or Rcv – the base radio is 
active
Base or AP-Base1 – the radio is configured as a base
Net <network number> – the network number of the radio
