Quadrus EZ Reader User’s Manual
Defaulting/Saving/Resetting
Customer Default Parameters
Customer default parameters (saved by <Zc> ) are the same set of parameters as power-
on parameters but are saved in a different, isolated section of NOVRAM. This allows a
user to essentially create a backup set of parameters that can be recalled in the event that
the current parameters or power-on parameters have been accidentally changed or no
longer desired.
It is important to note that a hardware default does not affect customer default parameters.
For example, a user that has inadvertently changed communication settings and saved
them with a
<Z> command, may not know the correct settings or doesn't have the capability
to communicate at those settings. By first doing an EZ button or hardware default to
restore the known Microscan defaults, the user can then recall the previously customer
saved settings with an
<Arc> or <Zrc> command.
Microscan Default Parameters
Microscan default parameters are contained in the firmware and cannot be changed.
Software Defaults
Microscan default parameters can be recalled (loaded into current settings) with <Ard>
command or recalled and saved for power-on with the <Zrd> command.
Hardware Default
If a software default reset is not possible, it may be necessary to reset the reader by shorting
(connecting) specific pins. This procedure has the same effect as the
<Zrd> software
command.
Important : For this reset to occur, this command must be executed within 60 seconds
after a power-on or a reset.
1. Apply power to the reader.
2. If using an IB-150, locate pins 7 and 11 on the host connector.
Caution: Be certain that the correct pins are located. Connecting the wrong pins could
cause serious damage to the unit.
3. Momentarily connect these wires (or pins) and listen for a series of short beeps.
4. Within 3 seconds, connect them again. A longer beep should be heard. If not, repeat
the process.
Default on Power-On
You can also use the EZ button to default the reader by holding down the EZ button while
applying power to the reader, provided that this feature is enabled.
