Differences between 2009 and 2010 Digital Sidecar???

Phil -

It isn't a difference between 2009 and 2010, it is that your 2009DSC has a very specific failure. The inhibit signal is likely shorted to "enabled".

You may be able to repair it by removing swarf. I'll check back with you in a bit, via PM.

Because the RSL and the relay outputs are on the same SPI chain, we continue shifting out all of that data and rely on the output enable signal of the shift register to disable the relays. As Eric suggested, your output enable signal seems to be damaged or shorted in that sidecar.

In retrospect, I should have been more paranoid and not only used the output enable signal but also zeroed out the relay data. Oh well... something to fix next year I guess.
