C-1 Serial Command Syntax
This section explains the structure and syntax of Omron Microscan’s proprietary serial commands – K
commands. K command are used to configure the V440-F Reader. All K commands are described in
Appendices D through N.
Omron Microscan readers are controlled by two types of serial commands: configuration commands and
utility commands.
 Rules that apply to both configuration and utility commands
•
Less than ‘
<
‘ and greater than ‘
>
’ angle bracket characters enclose the commands.
•
Commands and data are case sensitive. Characters must be entered as upper or lower case,
as specified.
Serial Utility Commands are sent during operations and are not followed by
<A>
or
<Z>
.
Omron Microscan’s serial configuration commands begin with a single “K” character followed by a 3-digit
numeric character, comma-separated command fields, and an initializing command, as follows:
<
K numeric character,data,data,...etc.
><
initializing command
>
An initializing command
<Z>
or
<A>
may follow the command.
• <Z>
initializes the memory and saves for power-on.
• <A>
initializes the memory but does not save for power-on, with the exception of Communications
parameters.
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 command fields (except the last) must be followed by a comma (without a space).
•
NULL cannot be used. The characters
<
,
>
, and
,
can be used, but only if entered as hex
values.
•
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 >
.
Commands can be concatenated (added together) in a single string. For example,
<K145 ,1 ><K220, 1 ><A>
enables
LRC
, sets
End of Read Cycle
mode to
New Trigger
, and resets the
data buffers without saving the changes for power-on.
