NF BC Configuring the Reader
5
The bar code labels change the reader’s current configuration, but the changes
are not saved to a configuration file.
Note: Quotation marks are required if parameter options conflict with the reader
configuration commands. For example, to set a preamble to BV, use $+AD"BV". If you
leave out the quotation marks ($+ADBV), the reader will mistake the command as
setting the preamble (AD) to no characters and changing the beep volume (BV). Type
two sets of quotation marks ("") to include one quotation mark in the command.
Configuring the Reader With IRL Z Commands
You can automatically configure the reader each time you run an IRL program
by including Z commands in the program. These Z commands change the
reader’s current configuration, but the changes are not saved to a configuration
file.
You should use this configuration method when you want to run an IRL
program that requires the reader to have a specific configuration. Include Z
commands at the beginning of the IRL program to modify the configuration,
and then include more Z commands at the end of the program to restore the
configuration to its previous settings.
For example, to change the display mode from buffered to transparent, insert
this Z command in your IRL program:
Z"$+DM1"
When the IRL program reaches this command statement, it configures the
reader and then executes the next command line in the program.
For help using Z commands, see your IRL Programming Reference Manual.
Configuring the Reader With PSK Functions
You can automatically configure the reader each time you run a PSK
application by including IM_COMMAND functions in the application. These
IM_COMMAND functions change the reader’s current configuration, but the
changes are not saved to a configuration file. For help using IM_COMMAND
functions, see your JANUS PSK reference manual.
