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:

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.
