If I try to update the drivers for such COM1 port and select Win7 drivers from Cypress installed folders then it does change the type of the port to USB serial port but still does not work. If you have 4 lines to test, have to guess at RX and unused line. Hooked up the power and ground to the router. I tried this same procedure with Win10 drivers from same Cypress folders and got the same results. Tried an old laptop with XP. ArkMicro Windows 7 Driver. If you try doing it from the computer end of the cable, how are you going to tell which signal is which and what the values are supposed to be?

The driver installation program finishes “correctly” however under Device Manager I can never see the Cypress device when zedboard is poweredup. You can google how to use a multimeter. If there is no signal, then you may be on the RX line.

I tried the USB device viewer but neither it or windows seems to think there is a connection. In my uneducated guess, I believe this means the colors listed above are correct.

And no, there is no SET color coding – manufacturers choose whatever they want. Black is the only wire to give a reading, and when i touch the red wire, and hold it to the positive lead my Win 7 PC actually recognized the cable.

CA Cable Not Recognized. I know its been said you can find the ground by measuring the ohms with a multimeter set to OHM. How else can you tell which wire runs to which pin if you dont crack open the end?

Well i have a hard time cracking open the end piece, is cabld possible to diagnose the wires with a multi-meter and how so?
Between each attempt I restarted windows after uninstalling previous driver and restarted again after installing new driver. Then compare the wire colour to the picture linked to in the wiki.
