The I/O (Input/Output Status) connector provides information about trigger function,
DAC, and TTL signals. Inputs must be at least 3.15 V for a high and less than 0.9 V
for a low.
The numbers on the I/O connector diagram correspond to the numbers given to the
definition of each of the pins. The I/O connector is a female, DB26, high-density
connector. The I/O cable (6050-0546) to access Trigger Input (Pin 1), Trigger Invert
Input (Pin 2), Frame Readout (Pin 7), Camera Exposing Output (Pin 8), and Shutter
Output (Pin 23) is provided with the PhotonMAX camera.
