Radio Summary

Select Radio / Radio Summary.

 

Hardware Type – Indicates which radio is in the receiver.

Hardware ID – Trimble Support uses this to identify the model of radio board that is installed in the receiver.

Hardware Version – Identifies which version of the radio board is installed in the receiver.

Firmware Version – Indicates the version of firmware for the internal radio.

Radio Serial Number – Indicates the radio's serial number.

Radio State – Indicates if the internal radio has any errors and the radio state, such as OFF, OK.

Radio Mode – Set the internal radio to transmit or receive if a receiver is a rover only or base only.

Country Code – Indicates the country configuration.

900 MHz Radio parameters

Network ID – The Network ID can be from 1 through 40.

450 MHz Radio parameters

Temperature (C) – Indicates the temperature of the internal radio when available. Reported in degrees Celsius.

Error Code – If an error occurs, this information can be reported to your dealer or Trimble Support to assist support.

Received Signal Strength Indicator (RSSI) – Is a measurement of the power present in the received radio signal. When more power is received, it is more likely that the radio can recover the data that was transmitted in the signal:

  • 0 dBm is equivalent to 1 milliwatt or one thousandth of a Watt.

  • -30 dBm is one millionth of a Watt.

  • -60 dBm is one thousandth of a millionth of a Watt.

  • -90 dBm is one millionth of a millionth of a Watt.

When static, radios can usually recover the data with an RSSI of less than -100 dBm. When moving around, reliable data recovery might require an RSSI of -85 dBm or greater.

Frequency Range (MHz) – Identifies the frequency range that the internal radio operates in.

Country Code – The country code of the country where the receiver is being used.

Tuning Step (kHz) – This value is preset, depending on the locality/country the equipment is being used in. Contact your Trimble dealer if this needs to be changed.

Channel Spacing (kHz) – Indicates the channel spacing of the internal radio. Can be either 25 kHz or 12.5 kHz.

Current Channel (MHz) – Current channel for the internal radio.

Wireless mode – Current wireless mode for the internal radio.

Channel Sharing Mode – For base mode only.

  • Off – The carrier detect mode is OFF. The receiver ignores other transmissions on your frequency and continues to transmit data. Latitude is in degrees, minutes, and seconds.

  • Avoid Weak Signals – The carrier detect mode is ON. If the radio detects another radio transmission on its frequency, it stops transmitting. When the channel is free of radio traffic, the radio resumes transmission.

  • Avoid Strong Signals – The carrier detect mode is ON, but the radio will only stop transmitting when there is a strong signal present. Receive level greater than -90 dB.

Enable call sign – This is a Federal Communications Commission (FCC) requirement for USA licensed users. This sets your radio to transmit your call sign in Morse code every 15 minutes.

RF Power level – If your receiver has an internal 450 MHz radio installed and if the 2 Watts radio option is loaded, you can set the receiver to 0.5 Watt or 2 Watts.

Max Number of Channels – Reports the maximum number of transmit and receive frequencies possible for the internal radio.

Current Number of Used Channels – Displays the number of receive only or transmit/receive frequencies already input.
