Safe Mode
In addition to the Run Mode that is used for normal operation, the Reader/Writer supports a Safe Mode
operation mode. The Safe Mode is used when you do not remember the IP address that is set in the Reader/
Writer.
If the Reader/Writer starts in Safe Mode, the following settings are always used. This allows you to access the
Reader/Writer even if you forget the IP address so that you can set the IP address again.
When the Reader/Writer is running in safe mode, some functions can not be used (Ex. RF tag communication and noise
measurement function, etc). When you use the Reader/Writer normally, start the Reader/Writer in RUN mode.
Starting in Safe Mode
(1) Connect the control signal line (violet) from the Cable to the GND terminal on the DC power supply.
Connect the other two lines (24P (brown) and 24N (blue)) to the DC power supply terminals.
(2) Turn ON the power supply to the Reader/Writer.
(3) The RUN indicator on the Reader/Writer will flash green
After the Reader/Writer starts in Safe Mode, use the Web browser or a Modbus query from the host
device to reset or initialize the IP address.
If an error occurs in the Reader/Writer, the Reader/Writer may automatically start in Safe Mode
