  • Page 2 You may need also need to refer to instructions that relate to the specific DATA lead that you use to connect the interface to your radio. For example, your radio may need certain parameters setting when using a radios 6 pin mini din socket. When using other cables, your radio may need other settings to be made.
  • Page 3 DigiMaster DataLink Interface. Simple 3 step setup procedure [1] Configure DM780 to use the new soundcard. [2] Configure DM780 to allow the soundcard to activate the radios PTT. [3] Configure Windows volume controls for optimum performance. [1] Configure DM780 to use the USB audio CODEC (soundcard in the DataLink interface).
  • Page 4 [2] Configure DM780 to allow the soundcard to activate the radios PTT. Open DM780’s program option window (F8). In the PTT “None” section, select;- Select “via soundcard PTT. The interface will automatically generate the PTT signal. DO NOT ACTIVATE YOUR RADIOS VOX.

    In case of problems: LED switches from GREEN to RED when operating software to TX. Some radios may go into TX but send no DATA. Some radios will not go into TX. Some radios such as Icom 706 require baud rate to be set at 1200. This selects the appropriate pin on the 6 pin DATA socket for PTT (1200 rather than 9600).
