1 ,2, 4, & 8 GRD Ground; 0V
3 DIGOUT Digital video output
5 & 6 VDD Positive power supply
7 SP Start Pulse for the shift register
9 & 10 Vn Negative power supply
11 & 12 Clock (CP) Clock for the shift register
13 & 14 GLED Return for the LED light source
15 & 16 VLED Power in for the LED light source
5.1 Inputs
here are five inputs:
Clock (CP): This is the input for the main sampling clock.
SP: This is the start pulse input for initiating the scan.
VDD: This is an input for the + 5V positive supply.
VN: This is the input for the -5V negative supply.
VLED: This is the input for the +5V power supply for the LED light source.
ote: Power return for the LED light source is GLED on Pin 13 &14, where as the rest of ground returns are on Pins 1, 2, 4, & 8.
DIGOUT on Pin 3 of the I/O connector is the only output I/O. Pin 3 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
