DGNA in Capacity MAX

DGNA allows Dispatcher to move subscribers to specific Talk Group.
The command replaces Contact Name on a selected Capacity Max Personality and Text on Display

Configuration – MSI side:
  • Firmware 2.10 or newer.
  • Radio Management -> CMSS -> activate license for DGNA (EID: Dynamic Group Number Assignment).
    According to the Article "HKVN4694A DGNA license - one per site". Which means the amount of DGNA licenses must be equal to licensed sites. If the license is not activated or not all sites are licensed the "License required" message will be shown in TRBOnet Dispatcher according to the answer from CMSS.
  • Radio Management -> Subscriber Access Control -> Enable option DGNA Rx for chosen Subscribers accounts.
