Hi Bert,
Your initial email said that you could talk to the RXAD through UniTool--it
was just the REF and amp you were having issues with.
Either way, if you're having trouble seeing the HPPR, you might check the
cover module. Is the installed preamp connected to the first free
connector on the ribbon cable? Are there any error messages on the
cover module or does it show "ready?" I ran into the issue once that
cf wouldn't complete unless there was a 1H preamp connected--if you have
left one of the BB or 2H preamps instead of 1H then you might be running into
that issue but I suspect if you just left the top one in then it's probably
the 1H module so it's okay. And check the tty port assigned to the HPPR
in cf--I forget which is which, but it needs to be assigned to either tty10
or tty20.
Cheers,Mike

Dear Mike,
thanks for the bit of clarification - in that case it would be a bit odd if
the RXAD can be talked to by Unitool *through* the DRU (it is required to
be connected and I get an error when talking to aqs/SBSB16 while the DRU is
unplugged from ethernet) but the DRU cannot be talked to by Unitool…
Actually the AV3 hardware manual says "The boards within the AQS that are
directly accessible via Unitool are: SGU, REF, RXAD, internal amplifiers.
"So I think we shouldn't get the syntax errors from the REF1 and AMP (but maybe DRU
In the end our main problem is the failure of "cf" during HPPR detection - which
may or may not have to do with these errors…
In the meantime I tried out a couple of more things:- swapped to the second
ethernet card in the (Windows) computer- swapped the PSD3 card- checked all
power supplies in the backside for any defective or almost defective capacitors
(measured ESD of all of them - all look OK)- all power supply LEDs are green-
tried to start the console with super basic setup (unplugged both SGUs,
unplugged IPSO from ethernet and still got the Unitool syntax error from
REF1 but connection OK to RXAD) - just to see whether some board "eats" too
much power- reduced HPPR stack to one single preamp- reinstalled Topspin (3.7.0)
So far to no avail - cf is still stuck at the detection of the last HPPR/2 module
(now the only module = P1)
Cheers
Bert
