Trying to erase XC9536, iMPact can not see cable?

After getting a ton of errors using ISE for the simple task of erasing a chip in-circuit, I downloaded iMpact 14.2. The bottom message is "no cable connection". I have a DLC9LP that I can see just fine in my device manager (Jungo, Win 7 x64). The status light is consistently red. When I try to connect a cable (using either auto connect or manual setup), it will blink and give the message "ERROR:Cse - A reference voltage has not been detected on the ribbon cable interface to the target system ( pin 2 ).  Check that power is applied to the target system and that the ribbon cable is properly seated at both ends.  The status LED on Platform Cable USB will be GREEN if target voltage is in the proper range and applied to the correct pin." and there is no change to the message at the bottom of the screen.

 

This happens whether I am connected to the board or not. I should be able to see the cable no matter if the board is connected or not right? Could there be a problem with my Cable?

This can occur if there is also a Parallel programming cable attached. iMPACT will interrogate the Parallel (LPT) ports first. If it detects a cable on one of those, this error might appear for that cable.

No other cables attached, I will look through that documentation. Thank you.

Woohoo! Finally got the light to turn green and recognize the cable, had to patch in variable power supply, inserted cap between VREF and GND on the ribbon, now getting "Erase failed"
