.1 Inputs
IGOUT is on Pin 1 of the I/O connector. This is the digital video output from the CI S module. Reflection off the dark target produces a
gital signal of “0” level, while the white reflection off the white target produ ces a digital level of “one”. T he amplitudes of the white and
ark are listed in the table below:

There are five inputs:
• Clock is on Pin 6 of the I/O connector. This is main clock input into the CIS module.
SP is on Pin 4. This is the start clock input to the CIS module. •
• VDD is on Pin 2. This is a +5V supply.
• VN is on Pin 3. This is a -5V supply.
• VLED is on Pin 8. This is a +5V supply for the LED light source.
Note: Power return for the LED light source is GLED on Pin 7 and the ground return for the CIS modules is Pin 5.
