You can use this connector to connect to a network which supports the DCS protocol like DCS or XLX.
The easiest way is to use the Quick setup to connect to these networks.
DCS and XLX servers usually do not need a valid D-STAR registration, but you can check your callsign's registration by clicking on the Check D-STAR registration button.
If you want to talk on a DCS or XLX reflector, set the URCALL on your radio to CQCQCQ, and the local module to D in the openSPOT2. Make sure you have not entered any space characters in your radio before or after CQCQCQ in the URCALL.
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 DCS001 A, or XLX001 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 REF/XRX servers by this method. Switching to REF/XRF servers or gateways this way changes the openSPOT2's active connector to the REF/XRF connector.
Here are some example DTMF command sequences:
Switching to REF servers:
*001Cwill change the active connector to the REF/XRF connector and connects to REF001 module C.
Switching to XRF servers:
B008Bwill change the active connector to the REF/XRF connector and connects to XRF008 module B.
Switching to XLX servers:
C0502connects to XLX005 module B.
C0904connects to XLX009 module D.
Switching to DCS servers:
D0501connects to DCS005 module A.
D0103connects to DCS001 module C.
As the openSPOT2 is designed to be always connected, the unlink (U) command is not interpreted. If you really want to disconnect, you can switch to a config profile which has the Null connector activated.
