irregularities during the usage of the device.
● The “Power” indicator does not light up after the power supply has been
switched on
○ Check if the power supply from the power adapter is working normally,
check also if the AC power voltage falls between 100V and 240V
● USB port can not be connected
○ check if the virtual serial port driver is installed
○ check if a virtual serial port chosen is correct.
○ check if reader serial port baud rate is 115200bps.
● Unable to connect through Ethernet port
○ The default IP address of the reader under factory setting is: 192.168.0.210.
If the host PC’s IP address is in the same network segment which the
reader’s IP address is in, for example “192.168.0.XXX”, the connection
will be successful. If the user forgot about the reader’s IP address, user can
recongure the IP address of the reader that is connected to the host PC
through USB serial port.
● Unable to read tag
○ Check if the serial cable or the network cable is properly connected. Any
disconnection or insecure connection will cause the command from the PC
not being transferred to the reader.
○ Please check if both ends of the RF connector has been tightened. Check
also if the tag is damaged. If problem persists, you may need to call the
Invengo service line for help.
