Serial Interface

Introduction
This chapter describes how to set up the decoder with a serial host. The serial interface is
used to connect the decoder to point-of sale devices, host computers, or other devices with an
available serial port (e.g. com port).
Note: The decoder uses TTL signal levels, which interface with most system architectures.
System architectures that use RS-232C signal levels require a conversion circuitry.
The serial host type requires proper configuration of the sysconfig lines, and typically require
scanning bar code menus as part of initial configuration.
Most computer monitors allow scanning the bar codes directly on the screen. When scanning
from the screen is sure to set the document magnification to a level where the bar code can be
seen clearly, and bars and/or spaces are not merging.
Serial Parameter Defaults
The table below lists the defaults for serial host parameters. To change any option, scan the
appropriate bar code(s) provided in the Serial Host Parameters section.
Note:
See Appendix A, Standard Default Parameters for all user preferences, hosts, symbologies,
and miscellaneous default parameters.
