Cross modes using an NXDN® transceiver
Using a D-STAR® network (openSPOT4 Pro only)
After you've set up and activated the D-STAR® connector, switch the modem to NXDN® mode.
Your outgoing callsign will be the callsign associated with the NXDN® source ID. If there's no callsign associated to the ID, then the callsign will be the Default callsign for cross mode calls. If this is not set, your outgoing callsign will be your radio's NXDN® ID as text.
An incoming call's source NXDN® ID will be set to the ID associated with the source callsign. If there's no ID associated, and the source callsign can be parsed into a number, it will be used as the source NXDN® ID. Otherwise the Default cross mode source ID will be used.
All calls coming from the D-STAR® network will be sent as a group call to the Default cross mode destination ID. If you don't hear calls on your radio then make sure this ID is in the selective call list (or SelCall is turned off), or it's the TX contact of the current channel.
Using a DMR network
After you've set up and activated the DMR connector, switch the modem to NXDN® mode.
The source DMR ID of your NXDN® calls will be set to the same value as the NXDN® call unless the Always use this ID in cross mode setting is enabled for the Default cross mode source ID on the Settings page, NXDN® settings section.
Your NXDN® calls will be sent to the same DMR ID as the NXDN® call's destination ID unless the Always use this ID in cross mode setting is enabled for the Default cross mode destination ID on the Settings page, NXDN® settings section.
The destination and source NXDN® IDs for an incoming DMR call will be set to the same value as the incoming call's destination and source ID unless the Always use this ID in cross mode setting is enabled for the destination/source NXDN® IDs on the Settings page, NXDN® settings section (or if the incoming DMR call's destination or source ID is out of the NXDN® ID range (0-65535)).
Private DMR calls are converted to NXDN® group calls.
Using a C4FM network
After you've set up and activated the C4FM connector, switch the modem to NXDN® mode. Only calls in DN (Digital Narrow) mode will be converted to your NXDN® radio. If someone transmits in other modes on the C4FM network, you will hear silence on your NXDN® radio.
Your outgoing callsign will be the callsign associated with the NXDN® source ID. If there's no callsign associated to the ID, then the callsign will be the Default callsign for cross mode calls. If this is not set, your outgoing callsign will be your radio's NXDN® ID as text.
An incoming call's source NXDN® ID will be set to the ID associated with the source callsign. If there's no ID associated, and the source callsign can be parsed into a number, it will be used as the source NXDN® ID. Otherwise the Default cross mode source ID will be used.
All calls coming from the C4FM network will be sent as a group call to the Default cross mode destination ID. If you don't hear calls on your radio then make sure this ID is in the selective call list (or SelCall is turned off), or it's the TX contact of the current channel.
