Factory Default Parameters
Factory defaults parameters are contained in the firmware that cannot be changed.
Software Factory Defaults
Factory default parameters can be recalled (loaded into current settings) with <Ard>
command or recalled and saved for power-on with the <Zrd> command.
Hardware Factory 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.
1. Apply power to the reader.
2. If using an IB-150, locate pins 7 and 11 on the host connector (see Table A-6 on
page A-5).
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.
Default/Reset Definitions
Defaults are original or saved settings that can be recalled, either by software or
hardware reset.
Defaulting occurs when default settings (customer or factory) are recalled. Default-
ing might be necessary if you have make temporary changes, communications
between the reader and another device are lost or interrupted, or you are using
incompatible equipment (for example, a terminal that is set at 38.4K baud communi-
cating with a reader that is set at 115.2K baud).
Resets (“A” commands) affect only the current settings (active memory) and are not
saved for power on or recall.
Active Memory is where the reader’s active settings are stored during use. These are
not available on power-on unless saved by a “Z” command.
