Concatenating Serial Commands
Commands can be concatenated (added together) to a maximum of 64 characters in a
single string or data block. Additional data blocks of 64 or less characters can be sent
provided there is at least a 10 ms pause between blocks.
For example,
<Kc1><Kh1><Ko1><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).
Serial Command Status Request
The status of serial commands can be requested by entering the command followed by a
question mark. For example, send
<Ke?> to request the status of Postamble. Com-
mands KT?, KV?, KW?, KX?, and KU? are used to request the status of groups of serial
commands (see table 3-1 on page 3-2).
Loss of Communications
Making changes to communications parameters such as Baud Rate, Parity, Stop Bits,
LRC, etc. without corresponding changes in linked device(s) can result in the loss of
menu access. If this should occur, default the scanner with the
<Zd> Restore/Save
Default Configuration for Power-on command as described on page 4-12.
CAUTION : Defaulting the scanner will reset all standard configuration parameters except
Scanner Type, Scans per Second, and Gain Adjustment to their original default values.
Note : Power must be available to the scanner during the default procedure.
Initializing serial configuration commands
To ensure that a serial configuration command will take effect, you need to follow it with one
of the operational commands below:
<A>
To reset but not save changes for power-on.
<Z>
To reset and save changes for power-on.
For example, to change Baud Rate and reset without saving changes for power-up, send
<Ka3><A>
.
To change Baud Rate and reset, saving the changes to NOVRAM, send
<Ka3><Z>
.
To ensure that a command was received and accepted, you can send the Show Scanner
Status command,
<?>
.
