I'm currently dealing with some RK8E Omnibus RK05
controller board sets.
I was unable to assemble even one stable RK8E from the stuff. I assume a
high failure rate. But I also assume that I have board revision
problems. I've been told that several revisions existed. And that there
were compatibility issues and some kind of paper (which I do not have)
telling what fits what.
I don't even know if the revisions are PCB revisions like "M7104 B2"
written in the etch or if there are also FCOs or alike that make boards
with same etch incompatible to other boards.
It is possible that some of your boards are actually for an RK8F instead
of an RK8E. I understand there were some blue-wire differences, and I'd
certainly not expect RK8F stuff to work anywhere but in the DW8E (and
with the rest of an RK8F).
But I have other boards flying around here as well.
Do stamps like "310 D" on the backside of the boards have any meaning
with respect to board revision or FCO level?
Another question is how to get different board revisions associated
with the right schematics.
I strongly appreciate any piece of enlightenment since I'm currently
getting depressed by that stuff. Even if I have bad boards - it won't
make sense to try to repair something if the whole is inconsistent in
itself.
I'd also be interested to see some kind of write-up about how to
distinguish these boards in the field.
