Can a 12V relay be driven by the LS DOUT of an MD4 supplied with 24V without protection or diagnostic issues?

Trying to actuate a 24Vdc coil for a skinner valve with the MD4. I know the MD4 only has LS digital outputs so I am wondering if we would need to use incorporate a voltage divider? I plan on using a relay for that coil as well. 

We have installed a brand new display in a battery powered rig this week. Its serial number starting with 2305 and production date of 230202.

It has been OK for a week but after the battery in the rig went flat, this line appeared:

Only thing I can think of was the battery was depleted and resulted in the display flashing when the battery got to a level where it was unable to power the module. It performed OK after the battery was recharged but after a few hours the line appeared. 

Anyone had this problem or similar before?

When powering on the MD4 the system message "IQAN-Master Wrong Id Tag!" appears on the screen.  This does not happen every time the machine is powered on but is getting more frequent.  Restarting or shutting off the power to the MD4 does not resolve the problem consistently.  The screen remains black when this issue happens.  Any help is greatly appreciated.  

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.
