Programming

Overview

The LS 1220 can be programmed by either a series of bar code menus, or by the host via
the RS-232 port. Select decode options and RS-232C parameters that are compatible with
your host system requirements.
Table 8-1 lists the available parameters and the descriptions location. Consult Parameter
Descriptions on page 8-3 for parameter types explanations.
The LS 1220 can be set to its factory default values by scanning the SET DEFAULTS bar
code. The defaults can also be set using the RS-232 port, refer to Programming Examples
on page 8-24.

Scanning Sequence Examples

Parameters other than default values can be set by scanning sequences of bar codes.
Table 8-1.Parameter Description Location contains the bar codes necessary to program the
scanner for each parameter selection.
In most cases only one bar code scan is required to set a specific parameter. For example,
to set the baud rate to 9600, simply scan the 9600 bar code listed under Baud Rate. If the
LS 1220 is equipped with an optional beeper, it issues a warble tone, signifying a successful
parameter entry.
To add or change prefixes and suffixes or customize the data transmission format, several
bar codes scans are required. This procedure is described in Parameter Descriptions.
