Serial Configuration Commands
Serial Command Format
Serial commands are of two types: utility and configuration.
Rules that apply to both utility and configuration commands
• A less than
<
and greater than
>
characters enclose the commands.
• Commands and data are “case sensitive.” That is, characters must be entered as upper
or lower case, as specified.
Serial Utility Commands
These are sent during operations and are not followed by a <A> or <Z> .
Serial Configuration “K” Commands
These begin with a single K character followed by a 3-digit numeric character, data fields,
and an initializing command, as follows:
< K numeric parameter,data,data,...etc.><initializing command>
An initializing command <A> or <Z> may follow the command. A <Z> initializes the
reader’s memory and saves for power-on; an <A> initializes the reader’s memory but does
not save for power-on.
For example, to enable UPC and save the change for power-on, send <K473,1><Z> .
To change Baud Rate and reset without saving changes for power-on, send
<K100,3><A> .
Serial Configuration Command Conventions
• All data fields (except the last) must be followed by a comma (without a space).
• The following characters cannot be used: , < > NULL .
• All fields preceding a modified field must be included.
• If there is no change in preceding fields, then commas alone can be entered in these
fields. For example, if only the last field in the following command is changing,
<K100,4,1,0,0> can be entered as <K100,,,,0> .
• All fields following a modified field can be omitted. For example, to change Baud Rate
only, send <K100,3> .
Concatenating Configuration Commands
Commands can be concatenated (added together) in a single string or data block. For
example,
<K145,1><K220,1><K450,1><A> enables LRC, sets End of Read Cycle mode
to New Trigger, enables Narrow Margins, and resets the data buffers (without saving the
changes for power-on).
