Parameters for R2 Lite UHF
In this dialog you can configure internal radio modem R2 Lite UHF.
- Select the type of Modulation for the radio modem.
- DQPSK modulation;
- GMSK modulation;
- 4FSK modulation.
- Select an appropriate operation Protocol for data transmitting/receiving. The protocol type is defined by the modem type and the selected modulation:
- TPS protocol is Topcon protocol and it can be used for DQPSK modulation only;
- PDL protocol can be used for GMSK and 4FSK modulation;
- TrimTalk protocol is Trimble protocol and it can be used for GMSK modulation only;
- Satel 3AS protocol is Satel protocol without Free Channel Scan (FCS) and it can be used for 4FSK modulation only;
- Satel 3AS FCS protocol is Satel protocol with Free Channel Scan (FCS) and it can be used for 4FSK modulation only.
- Select the output Power value for the base radio modem.
- In the Scrambling field you can select:
- On or (1-255) to activate Scrambling option — more robust data communication over high interference areas.
- Off to deactivate the Scrambling option.
- Do not set to save the previous setting of the Scrambling option.
Scrambling option depends on the selected modulation and protocol:
- for the GMSK modulation and Trim Talk protocol this option is automatically set.
- for the 4FSK modulation and Satel 3AS /Satel 3AS FCS protocol this option is automatically switched off.
- In the FEC field (Forward Error Correction) you can select:
- On to activate the technique to control errors in data transmission over unreliable or noisy communication channels.
- Off to deactivate the FEC option.
- Do not set to save the previous setting of the FEC option.
FEC option depends on the on the selected modulation and protocol:
- for the GMSK modulation and Trim Talk protocol this option is automatically switched off.
If this dialog was opened by clicking Config <selected modem>; command from the pop-up menu of the Status or Topo or Auto Topo or Stake <objects > dialog; it contains:
- Channel field. It displays the channel which was used in the previous session with this modem of the connected receiver. This line contains information about channel frequency, channel spacing and maximum transmitter output power for the channel (for the base modem only). To see all available channels of the modem, click the Get Channels button.
- Get Channels button. Click it to obtain all available channels of the modem.
- Start button. Click it to start transmitting or receiving of the correction data.
- Stop button. Click it to stop transmitting or receiving of the correction data.
Click
to open the pop-up menu containing additional options:
- Shutdown Radio - select the option if it is required to restart the radio modem. After the shutdown, the radio can be started by clicking the Start Radio button.
- Factory Reset Modem - select the reset the radio modem to factory default settings. This may be required if you need to return to settings recommended by the manufacturer, or in case the radio does not operate for some reason.
