This is how I 'rescued' a FX9500 that was not connecting over the network cable. For some unknown reason the FX9500 had lost all IP data and would not even respond to the default IP address of 169.254.1.1
Software. You need a serial terminal program such as Putty.
Hardware. You need a USB cable and / or a RS232 Serial cable to connect from the PC to the USB port of the FX9500. If you use the old style serial conection then you may also need a USB to serial converter.
From the FX9500 manual
Connecting the Serial PortThe FX9500 RFID Reader is equipped with one DB9 type RS-232 serial port for communication up to 115200
Baud. If using the serial port for RFID Reader communication, connect a serial cable from the COM port on the PC
to the serial port on the RFID Reader. The maximum serial cable length is 12 feet at 115200 Baud.
Connecting the USB PortsThe FX9500 RFID Reader is equipped with two USB 2.0 ports. The USB Type B port provides connectivity to the
FX9500 console. This connection is used to send commands and receive responses and is typically connected to
your server. The USB Type A port is used for external devices such as printers, external hard drives, or other
peripherals. For standard communications, connect a USB Type B cable to the RFID Reader and then to your PC or server.
The maximum cable length is 5 meters to the nearest hub, router, or computer.
Connect the reader to the PC using your choice of serial connection.
On the computer launch Putty ( or other terminal program)
For Putty:
1. Select the Serial button
2. In the Serial field add the COM port for the serial cable you are using.
3. In speed enter 115200
4. Click Open
The FX9500 console application opens in the terminal with a prompt
>>>Login with the command
reader.login( login=factory, pwd=HERCf95*..)Enter the command
com.network.1.ip_addressThis should show the current IP address of the reader.
ok 169.254.1.1>>>
If an IP address is given then you can connect via the web console using that address e.g.
http://169.254.1.1 BUT if the reader has a problem then this may be blank or none.
ok none
>>>
To reset the IP address enter the following command.
com.network.1.set(method=static, ip_address=169.254.1.1,subnet_mask=255.255.255.0,default_gateway=169.254.1.1)The IP address will now be fixed and you can use the web console to connect and set or reset the configuration as you need.
Remember that your PC must be on the same subnet as the reader so you may need to give the PC a fixed IP address of 169.254.1.10 to make the initial connection.
Paradoxically I hope this helps but you never have to use it!!
