@Networknoobie: judging from the picture, it seems the expander problem is either because the extension cable was not plugged in correctly, or the cable was mis-wired. Here is my evidence: all 8 wires on the extension cable should be parallel, in your picture, the orange wire on the OSPi side is on the bottom row, but on the expander side is on the top row. This can’t be right. The cable connectors are polarized so there should only be one way to plug it in. Please re-check the cable. It’s certainly possible that the cable may be mis-wired, but it’s quite rare. If you put the two connectors back to back, with the ‘notch’ facing up, all 8 wires should be parallel with no crossing.
