Does anyone have the pinout to make a Simple Signaling UPS Cable AP9827- USB to RJ45 for an APC ES 500 UPS?

This is the USB to RJ45 that connects the Battery backup to the computer

Note: The connector at the UPS is RJ50, not RJ45

I heard that there is a diode someware in the circuit, I already tried different configurations with no luck. I can't afford to spend $40.00 for a cable.

Do you really want to make one or just need one and had not thought about an adapter?


I googled "usb to rj45" and lots more came up.
