• Digital I/Os: 5 inputs and 4 outputs (open collector).
- 4 independent sink-driver auxiliary output signals, used to connect TTL or
non-TTL devices (up to 24 V). Two of the four auxiliary output signals can be
used as strobe signals.
- 4 independent opto-isolated auxiliary input signals (implemented using
high-speed opto-isolators).
- 1 opto-isolated trigger input signal (implemented using a high-speed
opto-isolator).
- Input signals have interrupt generation capabilities.
- The opto-isolated auxiliary input signals are debounced (that is, configured to
reject signals of less than a certain width).
- The debouncing time can be configured using MIL.
• Controlled-current output. 1 controlled-current output (CCS) designed to
provide variable current to a LED lighting device.
• Timers:
- 2 exposure timers. One is used to generate the exposure signal and the other is
used to enable or disable the strobe signals (available on auxiliary output signals
4 and 5) and the controlled-current output (CCS).
- 1 hi-drive timer. Used to control the time during which the controlled-current
output transmits the maximum current (500 mA) to the connected LED
lighting device. This allows the LEDs to reach a steady state quickly.
