• VDD is on Pin 2. This is a + 5 Volts supply.
• VN is on Pin 3. This is a (– 10 to –5) Volts supply.
• VLED is on Pin 8. This is a +24 Volts 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.
Video Output:
DIGOUT is on pin 1 of the I/O connector. This is the digital video output from the CIS
module. Reflection off the dark target produces a digital signal of “0” level, while the white
reflection off the white target produces a digital level of “one”. The amplitudes of the white
and dark are listed in the table below:

(1) The Tint is specified with a 2.0 MHz clock frequency. In operation the time
constants in the reference generator is set to match the initial exposure time,
hence the time constant will determine the optimum integration time. Note the
integration time is also a function of the clock frequency. Accordingly it is highly
recommended that the parameters be factory adjust for the specific
applications.
