I have issue regarding CAN bus critical error on the MD4,

can any one suggest me to reification above issue.

I am waiting for your valuable reply. 

Hello,

We are using a MD4-10 (IQAN-6) as main controller for our vehicle. Recently, a bluescreen appeared while we were disconnected from the vehicle via the controller's ethernet port connexion; we were measuring. When it disconnected, I also felt a small static shot from my laptop (I don't know if this is related to the error but it is something I have noticed when it happened). The error code is os_error(0x1000002) with run fault pid 90131. I have looked on IQANForum and I have seen this error before but not from the same source.

We are fixing the wire ethernet connector on the vehicle but is this something that has a precedent ?

Have you seen this type of error before?

Thanks for the support.

Best,

I am using a MD4-7 on my test bench for one month approximately.  It seems to be corrupted.  I can no longer send projects via ethernet or PCAN from IQANdesign 5 or 6.  I have also tried a coworkers laptop and failed.  When I send a project, the display momentarily blue-screens then restarts the existing application.  IQANdesign eventually reports "No Reply."

The only way I have been able to send a new application is in safe-mode by removing the ID tag resistor.

Are there any other recovery steps I can attempt before sending this display back to Parker?

We powered up 5 new systems, all identical programming and 2 of the displays show this error. 

We aren'y connected to the VREF A. We're trying to get some factory support but haven't been able to get any response on this. 

Hello,

Our company's electric vehicle is using a MD4-10 display/controller with the IQAN software. Yesterday, the MD4-10 suddenly started to show lines of color on it and turned white. After a reboot, the screen seems to open but only showing a white screen and we are not able to communicate with it through an IQAN ethernet connexion.

We are trying to figure out what exactly happen so we do not repeat this mistake on the spare display that we have. 
I believe something similar happen in 2015 on another post and it had to do with the supply being too low. But it was mentioned that that issue was fixed. Furthermore, we supply 12V to the Display with a 2 A fuse as well as the RTC protection circuit that is suggested in the manual. 

- Our negative connexion is connected to the negative of the 12V battery through the vehicle's chassis. However, we also supply everything including another MD4-10 the same way. Could this cause this type of issue ? Does it need to be directly connected to the negative of the 12V battery?

- Can a short circuit between the power supply and the RTC input cause a fault of the screen, or just prevent the screen from being turned off?

Thank you for your support.

Best.

I have a project where I am trying to stream a video of my cell phone to the MD4 display.   As I want to be able to view google maps on the display for an in cab display.   

I noticed in this post that it looks like the MD4s support HTTP streaming,  

https://forum.iqan.se/communities/5/topics/295-md4-updated-list-of-tested-functional-ip-cameras

And I found this app that will do HTTP streaming via MJPEG

https://github.com/dkrivoruchko/ScreenStream

And then I get an access point connected from my Phone, PC, and MD4 display. 

The phone has an ip address of 192.168.128.10:8080, and I can view the stream on the PC, but I cannot view it on the display.  

I tried to type in "HTTP//192.168.128.10:8080" in the URL and that didn't work, and then I tried just the port of ":8080" in the URL.    

Can you confirm that the MD4s support HTTP streaming and if so what port are you using, as I can change that in the app settings if its not 8080.  And how would I configure this in IQAN

Hi,

Are you aware of any solutions to use a mobile or any 3rd party display to present the information that's visible on the MD4. No input are supposed to take place, its more about presenting data visible to people around the machine. In this case a saw mill where the MD4 are located inside a control room limitied to the operator.

Ideal would be to have a wireless solution.

MD4-7 is stuck into this mode even when power cycling display. Anyone had si

milar issue? Any suggestion would help.
