JPI 700 data cable

[willerjim273]

I bought my 231 with 160 hrs SMOH. Unfortunately, the engine was corroded due to not being flown. I have her back now with a fuel leak issue yet tbd. Because it was missing on takeoff during the last flight along with the presence of fuel in lower cowl after sitting for 29 hrs, I figure looking at the data would be nice. So I need a cable. . Spruce has this one: https://www.aircraftspruce.com/catalog/inpages/edmpcinterfacecable.php

 

The data plug ( I believe- see pics) is way different from what is available to buy. Anyone seen a JPI data receptacle like this one??

And what about a converter?

My oldest laptop has a 15+ pin connector. 

 

Best way to do this? O refer me to archives?

 

Thanks

Go to the JPI website to find the parts...

Unless you want to do it yourself and build the parts...

The bits include a RS232 plug on one end of the wire that plugs into that socket...

Then you need a RS232 to USB converter...

use a modern laptop, download the software from JPI... plug in the USB...

Good to go...

Best regards,

Yes, I have one just like it. You also have to have the converter. JPI will (at least when I set mine up) tell you it has to be a "Keyspan" converter. In my experience, they are right. I bought one that should have worked, but didn't. I got a Keyspan and still using it.

That spruce part looks like the right cable. Don is right; don't bother with any other serial-to-usb adapter as the Keyspan seems to be the only one to work.

 

I got tired of using the ancient old laptop to download and had  my EDM700 converted to internal USB port when the display died. Works great.

 

Hope that you can sort your engine issues/

Here's the Keyspan USB-serial converter, if you want to use a laptop newer than 15 years old.

You will need that in addition to the serial-EDM plug cable above.  That cable is indeed correct, shielded-barrel end plugs into the EDM socket above your EDM mode switch.  Works like a charm.

Note that some people have opted for the USB box from JPI.  It's easier, you can just plug a USB memory drive into it instead of needing a laptop and cables, but at $200 versus $60, it's pricier.

I just use one of those cheapo ASUS tablet/computers to download data.  They're only about 1 lbs or a little more instead of a traditional laptop, and they work fine.

The coaxial panel connector is standard for JPI. I got tired of dragging my laptop out to the hangar and bought the USB download box which works great.

I download and log all the data from all my flights. So for me, ease of downloading was one of the many drivers to upgrade to the EDM-900. 

But not even the most modern of the JPI or EI engine monitors can't compare to Insight engine monitors when it comes to ease of logging and downloading data. The Insight monitors, the G2, G3, G4, etc, have an SD Card slot in the face of the instrument with an SD card installed. The factory SD card has enough space to log well over 2000 hours of flight time or more than enough for all flights from new to TBO. Of course to upload the flight, just eject the card, plug it into any laptop and download the data. It's positively 21st century tech

Willer,

I have the same setup as you.  From experience do exactly as carusoam describes and save the aggravation.  Downloading to the USB converter is the way to go.  Plug the USB in at home to your computer.  Also recommended joining SAVVY.  They have software that will allow you to view your data. Plus if you message them a service request from the data analysis page they will analyze the data with your flight debrief if you have an issue.  All good info to share with your mechanic.  Hopefully you have a mechanic who’s thought process is to go to the engine data as one of his first couple troubleshooting steps.

I got one of these gadgets too and it changed my life. While not cheap, it's money well spent and I no longer have to take blood pressure medication now that downloading the data is a frustration free experience.

Couldn't a simple jack to USB cable plugged directly into a laptop work? e.g. something like this

No, that's just a power cable.

It is appropriate this thread re-arose today.

The last time I tried to download my flight data, the JPI only downloaded stuff from 2 years ago. I fiddled with it enough to know I couldn't do any good. I called JPI and after some back and forth, they told me to do a "factory reset" and if that did not fix it, I would have to send it in to them. Their instructions for the reset were far from optimal. As fiddled some more trying to do the reset, I think I inadvertently messed up the K factor. Does anyone by any chance know about what that K factor should be on a K model with the JPI 700.

Here’s his post:

I was able to push out an initial copy of an app for Android that allows you to download from your older serial-based JPI EDMs (700, 711, 800) using your phone. If you supply a "3rd party" token from Savvy in the settings, it'll auto-upload once done as well, saving steps later. And best of all, no clunky laptop at the hangar.  

(Apple is much more restrictive on external hardware, so it's a bit harder there - but could be an option if there was enough interest.)

https://play.google.com/store/apps/deta ... jpi.upload

Required equipment:
* 9-pin serial to barrel connector cable to interface with the JPI
* USB OTG (on-the-go) cable, something like:
> USB-C: https://amzn.to/2HBjhon
> USB-Micro: https://amzn.to/2QkYusa
* USB Serial Adapter - the library should work with these. I have the first, which I leave in the plane:
> FDTI: https://amzn.to/2HBk4FR
> Prolific PL-2303: https://amzn.to/2W35P5M
> NOTE: JPI-recommended Keyspan devices will NOT work with Android

The data rate is configurable under settings as well - this must match what's set in the sub-program menu on your JPI. (PROGRAM > DUMP?, hold both buttons again for a submenu, then page to the FAST? y/n setting). Some adapters may see data loss at using the FAST rate - if having issues, try setting your JPI to "FAST? N" and set the app to match. If you download often, the slower speed really isn't an issue.

Hopefully it helps a few people out there...
