REF/XRF connector

You can use this connector to connect to a network which supports the Dplus protocol like REF or XRF.

The easiest way is to use the Quick setup to connect to these networks.

If you want to use a reflector, set the URCALL on your radio to CQCQCQ, and the local module to D in the openSPOT3. If you want to use a gateway, set the URCALL to the gateway's callsign and remote module. Remote module should be the last character of the URCALL. In this case, set the local module to a space character in the openSPOT3.

Note that if you are connecting to a repeater, you have to set the Reflector/gateway ID connector setting to the callsign of the repeater.

REF and XRF servers need a valid D-STAR® registration. You can check your callsign's registration by clicking on the Check D-STAR® registration button. Make sure you have registered your local module on the D-STAR® gateway registration system. If you have a registration, you have probably registered the "space" local module, in this case set your openSPOT3's local module to a space (empty) character.

Try remote module E on any reflector for the REF/XRF echo service (may not enabled on some servers).

Switching reflectors/gateways using your radio

URCALL/your call method

You can switch reflectors using your radio by starting a short call to their names as the destination callsign (URCALL), like REF001 A, or XRF001 A. Set the desired remote module as the last character of the URCALL. You can switch to gateways the same way. You can also switch to DCS/XLX servers by this method. Switching to DCS/XLX servers this way changes the openSPOT3's active connector to the DCS/XLX connector.

DTMF method

Here are some example DTMF command sequences:

Switching to REF servers:

  • *1C or *01C or *001C connects to REF001 module C.

Switching to XRF servers:

  • B8B or B08B or B008B connects to XRF008 module B.

Switching to XLX servers:

  • C5B or C502 or C0502 will change the active connector to the DCS/XLX connector and connects to XLX005 module B.
  • C9D or C904 or C0904 will change the active connector to the DCS/XLX connector and connects to XLX009 module D.

Switching to DCS servers:

  • D5A or D501 or D0501 will change the active connector to the DCS/XLX connector and connects to DCS005 module A.
  • D1C or D103 or D0103 will change the active connector to the DCS/XLX connector and connects to DCS001 module C.

Notes

The openSPOT3 will automatically set the local module to a space character if you are switching to a gateway, and to local module D if you are switching to a reflector using your radio.

Cross mode usage

The REF/XRF connector is a D-STAR® connector, but it supports DMR cross modem mode.

You can change servers using a DMR radio with a private call to a special 5 digit long DMR ID which has the following format: server type+number+module.

Server types:

  • 1: REF
  • 2: XRF
  • 3: XLX
  • 4: DCS

Number is the server number. For example, server type 4 and number 01 means DCS001.

Module is the remote module. 00 is module A, 01 is module B, 02 is module C and so on.

The number and module are always 2 digits. Example: starting a private call to ID 10102 will connect to REF001C (server type 1 (REF), number 01 and module 02 which is C).
