Safety Boards look at the trends and difference between the Galvo amp position signal output and the X-Y signals from the ILDA input. If the "Scan Fail" board sees the scanners stop moving or in some cases slow down too much, the laser will be blanked..
So In-X typically goes to the ILDA X+ lead and In=Y goes to the ILDA Y+ lead in most cases. Remember to join the grounds as well. Usually the card has to be adjusted to match the operating conditions of the galvo amps and signal input levels. That data would have to come from Kvant.
