ICI Insert Card Reader Option (PCM2 OPT7A)
The bar code reader provides a convenient means of entering a user ID number.
This card reader is an "insert" reader in that it requires the user to insert a card
with a bar code on it into the card guide. The bar code reader will read bar codes
over the speed range of 3-30 inches per second (ips) at the recommended density
of the encoded bar. A non-read is indicated by illuminating both the red and
green LEDs. A good read is indicated by illuminating the green LED only. The
reader is mounted in the lower cutout in the console panel's display panel beneath
the CRT.
The reader is capable of reading either visible bar codes or bar codes hidden
behind a special black filter. The reader is optimized to read bar codes whose
narrow bar is greater than 0.013 inches. However, bar codes with a narrow bar
width of 0.010 inches can be read with some slight deterioration of the high speed
scanning rate. The recommended distance from the edge of the card to the center
of the bar code strip is 3/8" (0.375"). The recommended width of the bar code
strip is 1/2" (0.50").
The ICI Bar Code Reader is a low cost unit capable of reading only the following
codes:
Code Type Recommended Density Number of Digits
Code 3 of 9 5 Characters/Inch (cpi) 6 Numeric
Code 3 of 9 5 Characters/Inch (cpi) 1 to 12 Alphanumeric
Interleaved 2 of 5 9 Characters/Inch (cpi) 2 to 16 Numeric
Note that Interleaved 2 of 5 must have an even number of digits.
