To connect a ROC 800 to a computer via serial port and set up the IP address using ROCKLINK software:
1. Create a DB9 female to RJ45 connector with specific wire configurations and combine it with a RS232 serial converter.
2. Plug the converter into the computer and connect an Ethernet cable to the ROC 800 port.
3. Open the ROCLINK 800 software, directly connect to the ROC, and set the IP address under the device information tabs.
4. The ROC 800 serial port is now connected and its IP address is configured for internet access.
