Program Management Commands
•
Software Reset, [<A>] . Initializes all serial configuration
commands in RAM and resets all counters and operating
parameters.
Note: Software Reset will cause the numeric counters in use to
lose their count; record all data that you wish to save prior to
sending this command.
•
Software Reset/Restore Default, [<Ad>] . Restores the ROM
default values to RAM then initializes them. Does not effect
Scanner Type, Scans per Second, or Gain Adjustment.
•
Software Reset/Read NOVRAM, [<An>] . Reads the NOVRAM
settings then initializes them to RAM.
•
Enter Configuration Mode, [<D>] . Enters the Menu
Configuration Program.
•
Software Reset/Save Parameters for Power-on, [<Z>] . Allows
you to save all but Scanner Type, Scans per Second, and Gain
Adjustment to NOVRAM. The values of numeric counters are
not saved by this command.
Note: The Software Reset/Save Parameters for Power-on
command can be executed at least 10,000 times. In normal usage
this will exceed the life of the reader. If frequent changes to the
operating parameters are required, it is recommended that the
<Z> command be used only when the current configuration has
been changed and the changes are to be permanent.
•
Restore/Save Default Configuration for Power-on, [<Zd>] .
Allows you to restore and save default settings for all but Scanner
Type, Scans per Second, and Gain Adjustment to NOVRAM.
Note: Power must be available to the reader during the default
procedure.
Defaulting might be necessary after temporary changes or if
communications between the reader and another device are lost or
interrupted, or if you are using incompatible equipment. For
example, a terminal is set to communicate at 9600 baud, but the
reader is configured at 38.4K baud.
•
Save Scanner Type, SPS, and Gain for Power-on, [<Zp>] .
Allows you to save the current settings for Scanner Type, Scans
per Second, and Gain Adjustment to NOVRAM. Once you send
this command, default values can only be recalled if you reenter
them individually and then save them again with this command.
Note: This command will replace the optimized factory setting
for Gain Adjustment with your new setting; record and save this
setting for future reference prior to sending this command.
