acq. path.
See pin 7 for more information.
Opto-isolated auxiliary input for acq. path 3 (positive).
Supported signals: trigger input 0 (main purpose) or user input 4.
TTL auxiliary output for acq. path 2.
Supported signals: exposure output 0 (main purpose) or user output 6.
RS-232 serial input to acq. path 2 of frame grabber (UART).
Ground
