Trigger wiring needs to have a good connection.

With a full 3TS1:
3TS1 jumper from 2 to 7 and 5 to 6.
Red wire labeled VCC goes to 3TS1-17
Black wire labeled exposure to 3TS1-4

With a short 3TS1:
3TS1 jumper from 2 to 5 to 18
Red wire labeled VCC goes to 3TS1-17
Black wire labeled exposure to 3TS1-4

Some systems are missing a wire from 3TS1-18 and the interface board J4-9


The generator needs to have bucky 1 enabled.
ATP SW2 bit 3 is calibration mode

FYI First 20 or so detectors my be set for photo diode (not line triggering). This is in the configuration menu for Vieworks.

power supply connectors (Cut end off foreign cord)
220AC SW - 26
0VAC - 10
