Slot Reader Module
Data Sheet – 2000/02/10
A. GENERAL The slot
reader module is well designed and constructed with high quality components.
The improved digitizer provides accurate reading capability, built-in different
wavelength light
sources for reading various barcodes, which are printed on different materials
to meet the
application requirement. Integrating this module to most of housings is an
easy-job. The TTL
output allows the slot reader to be universally accepted by most decoders.
*Available in two wavelengths
*Compatible with most exiting magstripe-reader housing.
*Single 5 volts power source.
*Standard signaling for connecting to most decoders
