Default/Reset/Save
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
essentially to 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 are 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 have the capability to
communicate within those settings. By first doing a hardware default to restore the known
Microscan defaults, the user can then recall the previous 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 and 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 <Zrdall>
software command.
Important: For this reset to occur, this command must be executed within 60 seconds of a
power-on or a reset.
1. Apply power to the reader.
2. Locate Pin 3 (Default) and Pin 7 (Ground) on the connector. (Access depends on wiring
configuration. May require an accessory cable).
Caution: Be certain that the correct pins are located. Connecting the wrong pins could
cause serious damage to the unit.
3. Momentarily connect the wires (or pins).
4. Within 3 seconds, disconnect and then reconnect the two wires again.
