Radio Connections
This page is used to define the properties of the internal or external radio used by the receiver. The following groups of parameters need to be defined:
• Internal Radio, if the receiver is a rover, or is being changed into a rover.
• External Radio, if the receiver is a base, or is being changed into a base.
These groups of parameters are detailed below.
Internal Radio
Use this area to set the internal radio used in a rover.
Parameter |
Designation |
$PASHS |
Power On/Off |
Enable this option to turn on the internal radio receiver right after you have clicked on the Configure button. |
RDP,ON or OFF |
Automatic/Manual |
Enable this option if you want the internal radio to be powered on automatically when the receiver is powered on. If this option is disabled, the internal radio will be powered on only on request from the receiver. |
RDP,PAR |
Type |
This field reports the type of internal radio currently used (a read-only field): • No radio • Auto-detecting...: The receiver is currently trying to identify the type of radio used. You need to refresh the whole screen (F5 key) to see if it has been able to come up with an answer. • U-Link Rx: The internal radio was detected as a U-Link Rx radio. • Pacific Crest: The internal radio was detected as a Pacific Crest radio. |

Channel |
Choose one of the available channels for this radio. (The channels are read from the radio when opening the Web Server Configuration tab.) |
RDP,PAR |
Protocol |
Choose one of the protocols below, depending on the type of radio transmitter used at the base: • DSNP (for radio transmitter P/N 800986, i.e. the old U-Link model first introduced in 1996) • Transparent (for all other radio transmitters) • Trimtalk for PacCrest |
RDP,PAR |
Airlink Speed |
Choose one of the baud rates below: • 4800 (mandatory to receive base data from radio transmitter P/N 800986) • 7600 • 9600 (base data from Pacific Crest radio transmitter) • 19200 Bd for PacCrest |
RDP,PAR |
Sensitivity |
Set the reception sensitivity of the internal radio used (High, Medium, Low). |
RDP,PAR |
External Radio
Use this area to set the external radio used by a base. After you select a radio type from the Type field, new fields will appear in the External radio pane for you to set additional radio-related parameters.
Parameter |
Designation |
$PASHS |
Type |
Select the model of the external radio connected to the base: • No radio • U-Link TRx • Magellan UHF: Radio transmitter P/N 800986 • Pacific Crest • ARF7474B EU: License-free radio for use in Europe • ARF7474A NA: License-free radio for use in North America |
RDP,TYP |
Following the selection of a radio type, new fields appear just above the Type field showing the current settings of the receiver serial port to which the external radio is supposed to be connected. Check/modify these settings.
Parameter |
Designation |
$PASHS |
Serial Port |
Specify the receiver serial port to which the external radio is connected. This field is set to A and grayed for U-Link and Magellan UHF. |
RDP,PAR |
Baud Rate |
(Pacific Crest only) Choose the baud rate to be used on this port to communicate with the external radio. |
RDP,PAR |
Mode |
Specify the type of this serial port (RS232 or RS422), if relevant (only port A may be RS422). |
MDP |
RTS/CTS |
(For license-free radios only) Enable or disable the handshaking protocol on this port. |
CTS |
Then set the radio parameters:

Designation |
$PASHS |
Load radio settings button |
(All radios except ARF7474A NA) First click on this button to load the current settings of the chosen radio type (“Loading..” is displayed in the Channel field while these settings are being loaded). As a result, the Channel, Protocol and Airlink Speed fields are refreshed to view the current radio settings. |
$PASHQ,RDP,PAR |
Channel |
(All radios except ARP7474A NA) Choose one of the available channels for this radio. |
RDP,PAR |
Protocol |
(For U-Link TRx and Pacific Crest radios only) Choose one of the protocols below: • DSNP (U-Link TRx only) • Transparent • TrimTalk (Pacific Crest only) |
RDP,PAR |
Airlink Speed |
(For U-Link TRx and Pacific Crest radios only) Choose one of the baud rates below: • 4800 • 7600 (U-Link TRx only) • 9600 • 19200 (Pacific Crest only) |
RSP,PAR |
Forward Error Correction |
(For Pacific Crest radio only) Choose whether this option must be enabled or not in the Pacific Crest transmitter:. • Button on: Enabled • Button off: Disabled |
RDP,PAR |
Scrambler |
(For Pacific Crest radio only) Choose whether this option must be enabled or not in the Pacific Crest transmitter:. • Button on: Enabled • Button off: Disabled |
