Needed to connect the 8020 to the computer (or mobile device)

8020 -> RJ45 -> DB9 -> USB -> computer

(8020 -> ethernet cable -> rj45-db9 adapter -> db9-usb adapter -> computer)

Some (tool-less) assembly required. 3 parts

• Ethernet cable
• RJ45 -> DB9 modular adapter
• DB9 -> USB adapter (choose the appropriate option for your computer)

	RJ45 -> DB9. The 8020 has non-standard serial port wiring, so using a modular adapter lets us adjust for that. The image to the left is a working configuration.	https://www.amazon.com/StarTech-com-DB9-RJ45-Modular-Adapter/dp/B00006IRQA

8020 -> RJ45 -> USB -> computer

(8020 -> modified rj45-usb adapter -> computer)

Use a modified RJ45 serial to USB cable to directly connect the 8020 to the computer. Modification requires a crimp tool and a passthrough connector. Reorder the wires so the resulting order is 1-4-2-3-5-6-7-8 (Move 4 to 2's position and shift everything toward the center. 1,5-8 remain unchanged. 1 is CTS). See this diagram
