For redundancy and convenience, I want use both an EIS 4000 and a Dynon to display engine data. Can I use the same sensor for both? How would I wire it to prevent any crosstalk between the EIS and Dynon? 

Thanks, 

Brad

   Which sensor? Most engine management systems will have

   several. Further, the panel mounted instrument is tailored

   to both the scale factor and power requirements for

   any particular sensor. The probability is that the

   two different systems are not identically configured

   for a particular parameter. There are no "standards"

   for the selection of sensors.

Does the Dynon have a serial port that can be configured to get EIS data?



I have an EIS4000 and a GRT Sport.  The Sport can configure one of its serial input as EIS input which drives the Sport's graphical engine page.  The sensors are connected only to the EIS4000.  The Sport displays the exact same information that the EIS does (only prettier   Of course GRT makes both products, so this kind of integration is expected.  Since the Dynon is a similar product, hopefully they have a similar capability!

Worth a try, but not likely that the data streams are compatible.



It is possible to parallel sensors - depending on the type and what the 

two devices do to energize the sensor.  That said, it is not likely to 

work with two systems that are specifically designed to work with 

particular sensors.



For instance, the EIS-4000 has some straight voltage inputs and has some 

inputs where it supplies current to the sensor.  The VDO pressure 

sensors are supplied current through a 470 ohm resistor in the 

EIS-4000.  If the line to the sensor were connected to a voltage input 

on the Dynon, they would both function happily together.  You would have 

to figure out how to calibrate the Dynon in that case, but that could be 

done by applying known pressures to the gauges.  Same thing goes for 

most of the temperature inputs (except the EGT and CHT) thermocouples.  

In the case of temperature sensor, you would have to apply known 

temperatures - boiling water, ice water, room temperature as compared 

with a good thermometer.



The problem you will run into is when both the EIS-4000 and the Dynon 

are supplying current to the same sensor - and looking at the specs it 

seems like that is the norm.  In that case, the only way to parallel 

them would be to somehow disable the current drive in one of them.  Of 

course, if you do that and that instrument fails then you get no output 

from that gauge.



I am actually doing the very thing you are trying to do.  However, I 

have an EIS-4000 and a BMA/EFIS One (I know, good news / bad news) that 

has inputs that can be configured to provide sensor power or just accept 

a voltage input.
