Scenario 3: Outputting corrections from a SNB900 radio to an TDL450/HPB450 or TRIMMARK 3 radio

Output corrections from the Trimble SNB900 radio through the Lemo port to an TDL450/HPB450 or TRIMMARK 3 radio. This is especially useful when using a GNSS smart antenna such as the Trimble SPS985/SPS986 and the construction site requires dual frequencies (450 MHz and 900 MHz) to be broadcast.

Solution

To configure the system:

  1. Use a cable to connect the SNB900 radio-modem (Lemo Port) to the SPS985/SPS986 GNSS smart antenna.

  2. Use the Siteworks or SCS900 software to output the corrections to the external SNB900 radio-modem.

  3. Connect the TDL450/HPB450 or TRIMMARK 3 radio to the Modem port of the SNB900 radio-modem.

  4. From the front panel of the SNB900 radio-modem, set output to both Radio and Lemo.
