Connect to the Serial Port with Microsoft Windows
To establish a physical connectivity between the router and a PC, you need to install a Microsoft Windows
USB.
Use the USB Console cable plugged into the USB serial port to establish this connection.ß
1. Connect the end of the console cable with the RJ-45 connector to the light blue console port on the router.
2. Connect the end of the cable with the DB-9 connector (or USB Type-A) to the terminal or PC. If your
terminal or PC has a console port that does not accommodate a DB-9 connector, you must provide an
appropriate adapter for that port.
3. Start a terminal emulator application to communicate with the router. Configure the software with the
following parameters:
• 9600 baud
• 8 data bits
• no parity
• 1 stop bit
• no flow control
