Yeah, I think the NOP issue is poised to drive me
crazy. I checked the grounds and serial connections todayand all checked
ok, hooked it all back up and low and behold NO Flashing. Taxi'ed the
plane for the first time for a few minutes (really fun). Taxi'ed back to
the hangar and started to run the Auto Program with what seemed to be some
succes and got about a third the way through when I started to worry about
the engine getting too hot (I wish the H2O temp was displayed in the program
mode), so I shut down Auto Program and the H2O was reading 233, so I am glad I
shut down.
Let it cool a bit and started to restart and NOW
the dang thing was flashing between NOP and the tach reading again.
GEEEESH.

BTW, did I mention I TAXI'ED for the first time
today <g>

w/RPM and a couple of other questions
Hi all, finally back from CO where we finally got the cabin plumbing
OKed by the inspector (and got the thing basically finished).
Tom is correct, NOP means Non Operational or Inoperative. In this
case it means the EC2 is not commuicating with the EM2. Either the two
serial wires between them are not connected properly or an ungrounded
condition or wiring error has blown one of the serial
connections. The Auto Program mode will not work in this
condition.

Tracy will have the final say, as he wrote the code, but most

NOP = No Operation. or Non Operational. Uh for the
life of me I can not recall when I started using that notation, but if you
flag part of a schematic, or assembly code, with NOP it is pretty
universal comment among geeks (EE's).
At least it isn't flashing "Fubar". :) Once I "inherited"
some assembly code on a project which had never been commented
(debug/maintenance nightmare). Thankfully the previous engineer had a hard
copy with his hand written Chinese notation along side the code.
Excited as I started to recognize a pattern of hand written characters by
the sections of code I couldn't figure out. Thankfully another
engineer explained what "fubar" looked like in Chinese.
