Thanks. I reloaded the driver from your site and that was successful, however did not resolve the problem. I was sure I had replaced all the cables from the PC to EMS but decided to do it again. Sure enough, the serial cable was bad! It now resides in the big round can, never to be seen...

Has there been any further information or solution found for this problem?  I have the same issue with my lap top that worked well until one day last week. At first I sucessfully updated my EFIS, but failed on the EMS.  Now it fails on both the EFIS and the EMS..  This is a Vista system...

Used 16 Gage from EMS Rack, 18 from Gnd to sensor base. Measured 1 MV from Rack to sensor base if my meter is any good. It's not a Fluke. LR

RV-7A, Using Sensor sent with Dynon package (single wire), 16 or 18 G wire probably, will have to look. LR

I have had low oil temp indications for some time now on my Dynon D120.  I have read thru many of the posts on the forum and tried multiple things to resolve the problem.  I installed a dedicated ground wire from the D120 rack to battery ground, Installed a dedicated ground wire to the shell of...

I finally had a chance to make another test flight for this issue a couple of days ago.  The Oil temp never got over 165 deg the whole flight and on average was 162 degrees.  OAT was comparable to the previous flight. I went back and reviewed the data log for the previous flight, and indeed the...

Yes I can send the info and log. I was going to fly agin today to see if I could repeat the symptoms but the WX was too bad. I will try again tomorrow. If you want the log anyway let me know, else I'll just try to recreate first. Thanks, Larry

This is a new one on me....  my Oil Temp readings on my D120 have been consistantly between 180 and 200 deg.  Yestarday on a normal flight the Oil Temp was around 185 until about one hour into the flight when it dropped to 160 and the alarm went off.  It stayed at 161 to 162 deg for the rest of...

Just a quick update FYI.  The problem is resolved, we have met the enemy and it is me.   This panel has an E-Bus, and it is fed directly from the battery.  The  AMP meter was floating when I was testing using the E-Bus as the power source - of course - current was not flowing thru the shunt...

Yes, I tried both wires on the same shunt post, no difference. And yes, the shunt is between the battery + and the load. I have not updated to 5.1 yet but saw no mention of a fix in that Version. Larry

Yes, this is correct. From pin 24 (Amp +) of the female harness plug thru the shunt and back to Pin 25 (Amp -) of the female harness plug I measure .5 Ohms. These are the Orange/Green and Orange Purple wires supplied in the Dynon Harness. All the pins on the male plug are visably intact, I...

The AMP Meter on my D120 fluctuates constantly from -10 to plus 15 Amps or so, nothing powered up except the D100, D120 and GPS 296 (Does it without the 296 as well). I have continuity from both of the dSub pins to the shunt, continuity from between the dSub pins thru the shunt and can see no...

I updated to V 4.0 today, battery charge problem resolved! LR

I loaded V 4.0 successfully on both my D100 and D120 today. :) This also corrected my battery charge problem in the D100. Thank you very much for the support along the way. Much faster load as well as promised! LR

Thank you, I shall wait... I was actually begining to think I was losing my mind, a small leap really.  My next attempt before waiting for Rel 4 will be to try my son's laptop, it's 50 miles away tho.  Still I would hate to have a $1000 laptop that can't do what I bought it for! Thank's for...

I tried loading the D120 EMS this morning and it failed with read errors as well. Once the read errors start ( this time at 2/2 4/9 1608/7700) they are persistent, every error is a retry. Since this was now in to an hour with no end in sight, I killed the operation after speaking with Eric...

I will try to backup the D120 tomorrow. No, I realize that an update is not an option at this point, that's why I quit. I'm using the USB-Serial I received with the unit. The Laptop is a new Toshiba, two weeks old, but that's not to say it works perfectly either. Thank's for your quick...

I am trying to backup the software before loading 3.0. After about 5 minutes I get Error messages that read Port# 1 Chip 4/5 Section 3/9 error this went on for about 10 minutes then said disconnected before reset. Failed. The unit was not frozen and I tried a second time with the same...

The EMS installation guide says the GP Contacts are "Info Items" only. I can't figure out what that means. Does it mean it will not provide an alert and/or audio signal? What I would like to do is have my stall warn sw input to a GP Contact, and have the EMS give a self clearing audio warning...

I have a D-100 and a D-120. Do I need an OAT Probe attached to each or will data from the OAT Probe attached to te EMS be fed back to the EFIS for DA and TAS calculations? Thanks, LR
