ADTpro with SSC II and straight through cable issues

I can't get my SSC II card to respond with the APPLE SSC prompt after typing IN#1.

I received my straight through cable (DB25M-DB9F) and the USB-to-DB9 adapter for my PC. Per the documentation online, I set the dip switches on the SSC II for terminal (arrow pointing down). I even tried setting the dip switches per the picture which shows a different dip switch configuration. My card is in slot #1. I even tried moving it to slot #2, and used IN#2. Nothing worked. Sometimes I get the "]" prompt, other times a "*" displayed, and sometimes I get nothing.

Any ideas?
