JPI Edm 830

[gsengle]

I've gotten the upgrade bug and I think a JPM EDI830 engine monitor would be a nice upgrade from my older 700.

Any reviews? I mostly like the idea of not having to wait for the screen to cycle through parameters to see what I want... And setting cht alarms etc

And it's pretty.

Greg - I've owned an 830 unit and upgraded to a 900 this past summer. I really liked the 830 but elected to upgrade to a 900 since the 900 came down in price and more importantly, it is considered a primary replacement for factory gauges.

The 830 displays everything the 900 displays except the fuel level in the tanks and an ammeter. Both are very readable in daylight and dim for night flight. You can set the 830 to cycle through just fuel readings, temps or both on the scrolling line. This is done by a switch on the panel.

The 900 can do the same thing but you do it through a button on the unit itself.

Here is a picture of the 830:

Here is the 900 in action:

Don't try to keep up with Marauder...

i installed it with the optional flush mount.

I would add the ease of downloading data via USB memory stick is a big plus.

To take advantage of the 830, I would consider the optional probes (oil temp, pres, oat, ff, etc) if you don't already have these.

When I set up my current panel, I had the 830 flush mounted, and the unit is great. Having said that, I would have chosen the 900 with the potential of eliminating some duplicate instruments. But, I had MP,Tach, etc installed at the immediate right side of the panel, and this yields redundancy and a cross check. I'm actually glad I did it this way. Still the 900 is primary, and the 830 is not.

Note: since these photos were taken, the 430 was replaced with a GTN 650, and the AERA 696 was replaced with a 796. Both in the same positions.

Since the 900 is a primary does it require new probes?

Like several others I started with an 830 and then upgraded to the 900 last summer when the price dropped.  It allowed me to remove the old gauges and not have to worry about keeping them working.  After selling the 830 and original factory gauges the upgrade cost me around $100.  This may be an attractive option if your plane has the Mortiz? gauges.  From what I have read replacements are expensive and parts not always available.

Some are re-used some are not. When I sold my 830 to another MooneySpace member I think he got new CHT/EGT probes and a few other new probes (OAT, FP? FF?).

I'm still waiting for you to adopt me Bennett... 

With the 900, I was able to remove the top row of gauges.

Definitely a sweet panel.

The only bad thing about Bennett's panel is to make room he is using the remote control feature of the 750 for the transponder and audio control, so if the 750 goes TU it takes those with it. Probably not a huge deal, but would a 650 instead of 430 fix that potential problem?

He indicated that the 430 was replaced with a 650. The 650 can support the remote transponder and I suppose he has it wired that way. The remote audio is not supported on the 650.

So if the 750 goes down, and its COM1, how do you switch over to the 650 and make COM2 the active radio?

It is configured to default to the second com. It doesn't have to be another GTN.

All good comments re: Com 1 / Com 2. I worried about this, and the aircraft was wired so that in the event the GTN 750 remote failed, the GTN. 650 would be primary. There was a time or two when the remote audio panel did not come up. A flip of the avionics master on and off "fixed" that.

I believe that the remote transponder can be controlled by the GTN 650, but I don't know that for sure. Never thought about it. I'll find out.

The 650 can run the transponder. My GTX-327 although not a remote transponder can be controlled through my 650.

Thank you. I will try that on my next flight.

I pulled up a photo of my GTN 650, and the transponder field shows ADS-B alt. I have a GDL 88. My Pilots Guide doesn't address changing from Transponder to ADS-B. I'll try tapping that area and see if it flip flops between them.

I think the 750 & 650 can control 2 transponders. I suspect you should be able to control the 88 or the transponder through either unit. Let us know what you find out.

I would suggest going out to your practice area and pulling the 750 circuit breaker for both nav and com and seeing what happens.

You'd get about 10hp back

Please show us more pictures of your crazy expensive glass panels. What was this thread about ... A JPI EDM-830? I can't remember ...

The day a thread on this forum stays on topic, is the same day I win the Powerball and one day before I call Pilatus to place my order.

Yep, we've had topic creep here, but questions were posted, and I will try and answer them. The way my GTNs are wired, each has a separate circuit breaker for the Com and a separate circuit breaker for the Nav components, and one for the remote audio panel, and another for the remote Transponder. I went down to my hangar and activating the electrical bus, I pulled each of the breakers, one at a time, to see what happens. If the audio panel CB is pulled, I cannot monitor two frequencies (com), but I can use Com 2 (GTN 650) as a normal flip flop radio. The volume control works just fine, and at most, the loss of the remote audio panel would be an inconvenience. I still had full control of the remote Transponder on the GTN 750.

I had mentioned that the Transponder window on the GTN 650 showed: ADS-B. alt, and I tried to see if it would toggle to Transponder. It does not Touching that box just brings up my N number and if GPS signals are not acquired, a failure message.

So far as I can tell, the GDL 88 is wired to the bus, as I cannot find a dedicated CB for it. I will contact the installer, as the only way I can turn ADS-B out is to pull the Transponder CB. I can turn off ADS-B in via GTN settings.

[ArtVandelay]

If they wired it the bus I'd have a problem with that.

My installer label it as ADSB and it's a 3 amp CB.

[Bennett]

As I said, I don't know if he piggybacked another CB, and I will talk to the installer about it.

Was the transponder test done with the 750 off? I think these units cross communicate with each other. If so, if the 750 goes offline, I think you should be able to control the GDL-88 transponder code.

I pulled both the GTN 750 Com and Nav CBs, and the Remote Audio CBs, and the 750 stayed on with Xs for the frequency boxes, and Xs where the audio panel allows frequency selection. The Transponder box stayed lit, and allowed me to change codes. If I pulled the Transponder CB I got Xs in that box. I don't know how to kill the GTN 750 itself with switches or CBs. Perhaps it is wired strangely, but the installation was made by a first class shop specializing in jets and turboprops. I can kill the GTN 750 by pulling it out of the tray, but I really don't want to do that until I am with an avionics tech. Too easy to bend a pin in the fittings.
