Outputting corrections using a TDL450/HPB450 radio-modem

The TDL450/HPB450 radio comes with a 5-pin Lemo to 7-pin Lemo connector with a power connection lead (P/N 66656-00):

  1. Connect the 7-pin Lemo connector to the serial port (Port 1) on the receiver.

  2. Connect the 5-pin Lemo connector to the TDL450/HPB450 radio.

  3. Connect the DC power lead to an external power source.

  4. Turn on the TDL450/HPB450 radio.

To configure the system, do one of the following:

  • Use the Trimble Access software to connect to the receiver. Set up the base station with the external radio. The Trimble Access software will locate the TDL450/HPB450 radio and then allow you to set the radio channel.

  • Use the web interface to configure the settings. Select I/O Configuration / Port Configuration. Select the Serial 1 / Lemo option and select corrections to be sent on the Lemo port at those baud rate settings (the TDL450/HPB450 serial interface is shipped with the default rates 38400 8/N/1).

Configuration software accompanies the TDL450/HPB450 radio if you need to change the serial connection baud rate.
