Radio Parameters for Digital UHF / Digital UHF II and TRL-35
In this dialog you can configure internal radio modem Digital UHF and Digital UHF II, external modem TRL-35. Also you can configure modem Digital UHF and Digital UHF II as repeater:
- Select the output Power value for the radio modem.
- Select an appropriate operation Protocol for data transmitting/receiving:
- Simplex protocol is ArWest’s proprietary protocol. This protocol is used for Digital UHF and TRL-35 radio modem.
- PDL protocol can selected for any modem types.
- TrimTalk protocol is Trimble protocol and it can be used for any modem types.
- Satel 3AS protocol is Satel protocol without Free Channel Scan (FCS). The protocol can be used for Digital UHF II only.
- Satel 3AS FCS protocol is Satel protocol with Free Channel Scan (FCS). The protocol can be used for Digital UHF II only.
- Select the type of Modulation for the radio modem. The modulation type is defined by the modem type and the selected protocol :
- you can select between DBPSK and DQPSK modulation for Digital UHF and TRL-35 radio modems with Simplex protocol.
- you can select GMSK modulation for Digital UHF and TRL-35 radio modems with PDL and TrimTalk protocol.
- you can select between GMSK and 4FSK for Digital UHF II radio modem with PDL protocol.
- you can select GMSK for Digital UHF II and TRL-35 radio modems with TrimTalk protocol.
- you can select 4FSK for Digital UHF II radio modem with Satel 3AS/ Satel 3AS FCS protocol.
- In the Spacing field you can select:
- 12.5 kHz- to provide more jam-resistant communication with low baud rate (4800 bps for GMSK and 9600 bps for 4FSK)
- 25 kHz - to provide communication with high baud rate (9600 bps for GMSK and 19200 bps for 4FSK)
- Do not set- to save the previous setting of the Spacing parameter.
The parameter depends on the chosen protocol, modulation type and link rate.
- 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 protocol and modem type:
- for the Simplex protocol you can activate, or deactivate, or stay previous Scrambling setting for Digital UHF and TRL-35 radio modems. To activate the option you need select a seed for pseudorandom sequence generator (the value from 1 to 255).
- for the PDL protocol you can activate, or deactivate, or stay previous Scrambling setting for Digital UHF, Digital UHF II and TRL-35 radio modems.
- for the Trim Talk protocol this option is:
- automatically set for Digital UHF II radio modem.
- saved previous Scrambling setting for Digital UHF and TRL-35 radio modems .
- for the Satel protocol this option is automatically switched on for Digital UHF II radio modem.
- 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 selected protocol and modem type:
- for the Simplex protocol you can activate, or deactivate, or stay previous FEC setting for Digital UHF and TRL-35 radio modems.
- for the PDL protocol you can activate, or deactivate, or stay previous FEC setting for Digital UHF, Digital UHF II radio and TRL-35 modems.
- for the Trim Talk protocol this option is:
- automatically switched off for Digital UHF II radio modem.
- saved previous FEC setting for Digital UHF and TRL-35 radio modems.
- for the Satel protocol you can activate, or deactivate, or stay previous FEC setting for Digital UHF II radio modem.
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. 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.
