Adding frequencies for the 450 MHz internal radio using the WinFlash utility

If your receiver has the optional internal radio installed, you can use the WinFlash utility to add receiving frequencies to the default list.

You can also use the web interface to add and manage receiver 450 MHz frequencies.

If you purchase a transmit upgrade (after initial purchase), the broadcast frequencies must be programmed using a .set file obtained from a Trimble service provider.

1. Start the WinFlash utility. The Device Configuration screen appears.

2. From the Device type list, select the receiver.

3. From the PC serial port field, select the serial (COM) port on the computer that the receiver is connected to.

4. Click Next.

   The Operation Selection screen appears. The Operations list shows all of the supported operations for the selected device. A description of the selected operation is shown in the Description field.

5. Select Configure Radio and then click Next.

   The Frequency Selection dialog appears.

6. In the Wireless Format group, select the appropriate channel and wireless mode. The wireless mode must be the same for all radios in your network.

7. In the Specify Frequency field, enter the frequency you require.

8. Click Add. The new frequency appears in the Selected Frequencies list.

   The frequencies that you program must conform to the channel spacing and minimum tuning requirements for the radio. To view this information, click Radio Info. You may select either 12.5 or 25 kHz channel spacing. All radios in your network must use the same channel spacing.
   

9. When you have configured all the frequencies you require, click OK.

   The WinFlash utility updates the receiver radio frequencies and then restarts the receiver.

   You can only configure receive frequencies. The FCC-approved transmit frequencies must be specified and configured by Trimble.
