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
>
character 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>
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
imager’s memory and saves for power-on; an
<A>
initializes the imager’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 ).
• NUL cannot be used. The characters
<
,
>
, and
,
can be used, but only if entered as hex
pairs (see
ASCII Character Entry Modifier
on page 3-32).
• 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>
.
