The OP8110 is pre-configured with an IP address (an identifying label will be attached to the unit), but it may conflict with your network infrastructure; you may need to change the IP address for your 4QPA. The best way to do this is to directly connect your OP8110 to your host computer (laptop, etc.). (Be sure to contact your IT department to obtain a valid IP address from them).

Before you begin, make sure your computer has a serial terminal program installed; you will need it to access the "OP8110 Recover" application. If there is no serial terminal installed, you must install one (such as MobaXterm) to access the OP8110 configuration application. The Mini USB Cable enables users to connect the OP8110 to a PC to access the IP address modification interface. It also allows users to perform various troubleshooting or reflashing activities.
