OK, there really was no echo of the command.

Good:

Interestingly, there had been a failure just before that, setting up the read for the previous exposure (27115):

And that image looks like the voltages really were not changed from integration to readout.

I'll discuss with Hope.

See INSTRM-1282 – that has some stats and is not confused with a command collision problem. Should probably have kept that one and closed this one.....
