Configuring the internal transceiver

Use the WinFlash utility Internal Transceiver Configuration dialog to configure the internal transceiver.

To view a list of all radio information, including the current configuration, click Radio Info.

  1. In the Internal Transceiver Configuration dialog, select the current channel. This determines the radio operating frequency.

  2. Select the wireless mode, which determines the over-the-air communications parameters.

    To reduce battery consumption on your base receiver, set the wireless mode as high as possible. For example, 9600 bps (bits per second) consumes half the power of 4800 bps for the same data format and time of operation.

    All radios in the network must be configured with the same wireless setting.

  3. Select the appropriate operating mode, depending on how you intend to use the receiver. For example, select "Base with No Repeaters".

  4. For base modes only, select one of the following channel-sharing configurations: (this is not available for rover modes)

    • Off. The carrier detect mode is off. The unit will ignore other transmissions on your frequency and continue to transmit data.

      It may be illegal in your country of use to set channel sharing to off. You may be subject to penalties or fines based upon the specific licensing requirements of your country of use. Please consult your radio license documentation or licensing agency for operational guidelines.

    • Avoid Weak Signals. The carrier detect mode is on. The radio will cease transmitting if it detects another radio transmission on its frequency. It will resume transmission when the channel is free of radio traffic.

    • Avoid Strong Signals. The carrier detect mode is on, but the radio will stop transmitting only when there is a strong signal present (receive level greater than 90 dBm).

  5. If you are operating in base mode, select the Enable Station ID check box and then enter your call sign in the Call Sign field. This FCC requirement is for U.S. licensed users. It sets your radio to transmit your call sign in Morse code every 15 minutes.

  6. To update the configuration, click OK.

    In the Status dialog that appears, select an option to return to the main menu or to exit the WinFlash utility.

You can print or save the radio configuration information for future reference. If required, you can fax or email the file to Trimble Support to aid in troubleshooting radio issues.

Updating the frequency list

You can program the internal transceiver modem with a list of up to 20 frequencies, which are stored in non-volatile memory. This list is pre-configured based on the frequencies that you requested when you ordered the unit. Government regulations stipulate that only manufacturers or authorized dealers can create this frequency list and that all frequencies programmed into a unit must comply with the host country regulations. If you need to add, delete, or replace frequencies, contact your Trimble dealer, and provide the radio modem serial number and an updated list of the frequencies you require. Once you receive the frequency file, you can upgrade the radio using the WinFlash utility.
