Katie, Will it pick up the GPS position from a data stream (external) to eliminate one more antenna?
Yes. It can take an RS-232 GPS input thru one of the serial ports. I would use the Mini's antenna instead of another, though, because the GPS aids the attitude calculation if there is no remote magnetometer. If it's a backup, I'd want the Mini to be self-contained.
I was disappointed enough about the NC formation flying clinic being cancelled and now I find out I could have seen the Mini on some of the teams planes. Hopefully I'll have mine by the May reschdule.
Can a single magnetometer be hooked to both an HX and a Mini-X, or does each need its own magnetometer?

The OAT sensor uses resistance to help measure the temperature. Splitting off to two units would affect the resistance and throw off the temperature reading.
(What Bob said!)
There is a reason this won't work. They are most limely thermistors which are biased thru a resistor. It would be easy to build a little isolation circuit, though. Or just feed it to the mini, forget using the EIS for this.
My opinion, and you get what you pay for here, is hook the OAT to the EIS and it will feed the HXr which will then display, OAT, winds and true airspeed.
I'm not sure but I think if you interlink the Mini and HXr the mini will also display the same information. I'll check that and get back.
I would move the OAT wires to the mini for now. EIS will only lose the ability to display OAT. Mini will gain the ability to display OAT, TAS, and density altitude.
When you get an HXr, switch OAT wire back to EIS. It will then send the data to the HXr, and from there to the mini - everything will have it.
Edit: I cannot believe the OAT probes would not be the same, but check with GRT when they get back from FL.
The OAT probes are the same for EIS, EFIS and Mini.
The magnetometers are different-- less wiring for the Mini.
We did this on Widget's RV8.I am considering removing my first generation D-10 and replacing it with a Mini-X. Has anyone done that or have an idea of what would be involved? I am looking for a short term primary display to be ultimately replaced with a larger unit and move the Mini to backup. The hole in the panel would have to be enlarged. I prefer not to do major surgery at this point but that will be coming when I decide to pull the trigger on the whole new panel/IFR capabilities. I don't want to take it out of service right now for the time frame to do the major do-over right now.
Thanks.

Just received a call from Jon @ GRT - our Mini-X is going out the door this afternoon. Yippeee!
I didn't think to ask about the next production batch and its timeline - sorry.
Hi katieb, im still unsure of the answer, please tell me if I am correct about this: the mini x or ap will not now or ever have ems display flip-flop capability similar to the mgl xtreme.
When did you place your order?
I placed the order early in December - around the 3rd, I think. First production run of Mini's seems to be 10 units for retail customers. Ours is one of those first 10, so it looks like we were pretty early in the order queue.
I'm really itching to get my hands on this thing as it's the last component required to complete our panel upgrade - I've had a gaping hole in the panel, ready to accept the Mini, since late January. It will be very nice indeed to finally have it filled with some gee-whiz hardware! At some point I'd like to trade our 6.5" HS for an HX and to that end have listed the HS display for sale in the classifieds section.

I haven't been able to find this on the GRT website or here on VAF... what are the power requirements of the Mini B? IE, how much current (at 14V) should I budget through my VP-X?
Thanks!
Russ
The Mini draws about a quarter of an amp at full brightness. So, a 1-amp breaker (or equivalent VP-X setting) is recommended.
Working on the Mini manual now, in fact...
Correct-- For engine capability, your best option would be a 6.5" Sport which is a full-featured EFIS with PFD, moving map, internal GPS, and the ability to display engine information from the EIS for $2,600.
Katie,
Does that mean the mini won't ever have engine capability? From your posts last year I understood there was an intention to produce a version of the Mini to supersede the EIS-4000 (etc).

Katie,
Can you explain what "voter for Dual AHRS" in the product description means?
Thanks,
Andy
The voter comes into play if you're using a GRT Horizon system as your primary instrumentation and you have dual AHRS. Through the inter-display serial link, the Mini can serve as the tiebreaker to decide which AHRS to disregard if the two main AHRS units disagree. Normally there are internal calculations done to monitor and throw out bad AHRS data, but the addition of the Mini attitude data provides an even greater degree of certainty.
Didnt the space shuttle use the same kind of system------triple redundancy and best two is what is presented???
Nice!
Thank you Russ.
It's going to be a tight fit in my panel. I have exactly 4.35in. between the face of the ASI and Altimeter and about 0.05in. on each side behind the panel.
The good thing is that I will have the maximum EFIS screen size that will fit without major remodeling of my panel.
