Particularly from a GMC-800? Preferentially the Logic-Pulse should have 3.3V, active Hi, Pulse Width 100...150 µs.

I am prepared to solder a connection onto the board!

Thx! The only LED I see is a 2-color LED with 4 pins, which makes it difficult to find the middle one ;-)

But on testing the 2 outer pins seem to carry the same signal. This is an active Low of 2.0V and a width of 720#181;s.

Are you sure this is the signal for counting? Because its lenght limits any counter to 1 / 720 #181;s or below CPS=1389, CPM=83333?

middle pin of LED but it is active low and is an open collector when not active.
