DMRplus dongle connector
You can use this connector to connect to a network which supports the DMRplus dongle protocol like DMRplus, Phoenix, DMR-MARC, XLX.
The easiest way is to use the Quick setup to connect to these networks.
You can change the used reflector ID by starting a short private call on your radio to the desired reflector ID (between 4000 and 5000).
Cross mode usage
The DMRplus dongle connector is a DMR connector, but it supports C4FM and NXDN cross modem modes. If you use a C4FM radio, make sure it is in digital narrow (DN) mode, otherwise your calls can't be converted and only silence will be sent to the network.
If you are using a C4FM radio, you can switch reflectors from your radio by entering Cross mode group call DTMF code (by default it's *) followed by the reflector ID in DTMF code.
Example: to switch to reflector 4770, enter DTMF code
