| Subject: | Vans RPM Transducer IE VTACHGEN 12 |
Bob,
I got their website from Van's, http://www.instrumentsales.com/ Vans
could not give me any additional documentation. The website is rather
limited. The way the Dynon doc reads is simply to set the pulses/revs to
your particular equipment. I talked to Dynon and they admitted that this
combination has been used before (and recommended because they don't
sell an RPM transducer) but they do not document or support it directly.
Yup, looks like a little experimenting is in order. I'll post my
findings to Van's and the list as to make life a bit easier for others
in the future.
Thanks
Glenn

Seems like all the Van's folks use the EIS 4k, I'm using the Dynon 180
which is similar but different.
What you're needing is the SCALE FACTOR for the transducer
in pulses per revolution of the engine crankshaft. No doubt
the setup instructions for the Dynon will tell you what
calibration code or dip-switch setting to use for that
particular transducer scale factor.
Unless someone on the list has installed that combination
of hardware items or incidental access to those two values
you're going to have to do some legwork. Does the
transducer have a brand and part number on it?

| Subject: | db connector hold-down screws |
Greetings...
I remember seeing an article on how to fabricate hold-down screws for db connectors
installed with no shells, but now can't locate it. I know it's not exactly rocket
science,
but would like to re-read the article. I'm pretty sure it was aeroelectric list
related...
Thanks!

*I had a problem with the DB9 on my Lightspeed ignition coming loose. A
Lancair builder put me on to these screws
AN500-AD4-7*
which I ordered from aircraft spruce. They are drilled fillister head
screws and were perfect for the task.

J, Bob posted some alternatives here:

Hopefully that's what you were after.

| Subject: | Pitot pressure switch |
Does anyone know a source for a pressure switch I can put in the pitot/static system.
I'd like to disable the flaps-down function if the airspeed is above some
reasonable value. I can find electronic sensors, but I'd like to eliminate
any electronics for simplicity.
Thanks,
-Tom

Take a look at these.
http://www.omega.com/Pressure/pdf/PSW21_PSW22.pdf
They're available directly from Omega.

There's some on ebay right now . . .
