SE 1223 Integrated VLD Scanner
Overview
Your SE 1223 Integrated VLD Scanner is a miniature, vis-
ible-laser scanner with an integrated decoder. The SE 1223
scanner contains an inboard microcontroller that scans and
processes bar codes into ASCII data.
The SE 1223 contains a miniature scan engine, on board
voltage monitor, a watchdog timer, two hardware hand-
shaking lines, and an EEPROM for storing decoder parame-
ters. It also provides over-temperature protection that turns
the laser off if the temperature rises above acceptable limits
(50
_
C).
