Hi Ken,
Yes, this card is the HSCE, and not the latter. I cannot fully answer your question about the size of the G-file, as I am uncertain where to look. I am only parroting what I see in the processor error tab under fault conditions.
In setting up the card, I followed the manual to the best of my ability bit-setting the required parameters for configuration and set-up, but fear I may be missing something there.
My suspicion is that I have somehow missed a required setting and the system check-sum is kicking out this fault code. ???
