[wxsig] Need t238 help

I need some advice.

I run an older T238 with the standard temp/wind/rain. Except for recently
losing a microprocessor (replaced with a T238A) to lightning, it has been
running just fine since shortly after it came out. Except for the PITA of
recalibrating, it has worked fine since replacing the microprocessor chip a
couple of months ago.

I decided to run the X1W2(R2) humidity sensor so bought and assembled the
kit. I did all the prelim checks including testing for availability of 5VDC,
packaged the unit, and put it on the roof. Now here is what happened...
1. I turned the system back on and it immediately came up with temp, wind,
and rain readings.
2. I went to the sensor menu and turned on the humidity sensor, and said
'no' to making the temp sensor the main one.
    o Now it goes through the 'setting up tnc', comes up with the '...wait a
moment' prompt and comes to a dead stop
3. In the process of checking, I went to the sensor setup menu and looked at
the temperature sensor - it is seeing both sensors and lets me chose which
one I want. continuing on, the end result is the same - hangs at '...wait a

As far as I can tell there is no way to shut off the humidity sensor. Also,
it appears I cannot get anything from either the computer rs232 port or from
the 'debug' rs232 port.

Any good ideas would be appreciated!
