After you change these parameters, all packets, including
any future configuration packets, must use the new
control characters. We recommend using the tilde and
ASCII character code sequence when sending this packet
multiple times. Also, set the packet delimiters to
characters within the 21 hex to 7E hex range.
Example {I,E,"~123~044~034~124~125~126~094"¦}
This does not change the control characters, but it enables the immediate
commands by defining the caret symbol (~094) as the command identifier.
Sending Verifier Upload Commands
Immediate commands consist of a three- or four-character sequence you can
send in a packet or embed in your application. Each command must be sent
separately.
Syntax control character_immediate command
The printer can accept only one immediate command at a time. Sending a
command before the previous one is completed can result in an error.
Command Description
^VLE Enables verifier data logging.
^VLD Disables verifier data logging (default when the printer is reset).
^VLU Uploads the log file to the last port that received host data (serial, parallel,
USB, or Ethernet). Repeat this command until data is successfully uploaded.
Data can be cleared after it has been uploaded.
^VLC Only clears the data that has been uploaded, not all the logged data. Data is
cleared with this command after a successful upload. We recommend clearing
the log file after uploading.
Example ^VLE
Enables logging of scanned data from the verifier.
To prevent a loss of scanned data, we recommend uploading the data daily.
The maximum number of scans depends on the bar code data length and
memory. Generally, the printer can hold up to 7,000 scans. However, the
scanned data is saved in RAM, so it is cleared when you turn off the printer
or experience a power loss.
Note: After the maximum number of scans is reached, no error is
generated and subsequent scanned data is not logged.
