You can hook it up to any 12 power source Ronnie. Use the screw terminals. From memory 1 is +12V and 2 is GND. Check with a multimeter first though, continuity between GND on the 4 pin connector and 2 on the screw terminal should confirm my memory!
You’ll see the PIN2DMD logo.
Hold in one of the 2 buttons while powering up presents the config menu.
Cheers Mike, then I can put it away until spring has sprung!
