Troubleshooting
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.
IP address
Subnet mask
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, please start the Reader/Writer in RUN mode.
Starting in Safe Mode
(1) Connect the control signal line from the Cable to 0 V on the DC power supply. Connect the other
two lines (24P and 24N) 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, reset or initialize the IP address from the Web browser or
host device.
If an error occurs in the Reader/Writer, the Reader/Writer may automatically start in Safe Mode
