Hello,

Our company is using the MD4 Parker Display for the logic of the exterior lights system on a electrical vehicle. We are currently in the process of certifying the system for the FMVSS 108. In said certification, there is a minimum amount of cycles that the lighting system has to respect. Usually however, the system contains a module that does the logic and in our case that logic is in IQAN. So is there an equivalent for the MD4 module, like the MTBF(minimal time before failure) for example, to prove that the exterior lighting system can support 175,000 cycles. 

Thanks for your help.

Hi 

    The situation happened after flashing software for MD4-7.   I can't link to MD4-7 via CAN or Ethernet now that means i can't flash software again.  The system still appears images but it will enter blue screen state like photo if i sent some commands to MD4 by any CAN channels.  I try to shortly connect address PIN to enter safety mode but seems no influences.   Who has any suggestions for me to solve this issue ?  How to re-flash software MD-7 ?

Hi,

We're using a MD4 display with IQAN Design 6.06 and during one of our session of sending the project over to our MD4 (meaning a blue screen was displayed) the module lost power and shut down. After rebooting it, the MD4 display did not reopen and even if we power it separately with an external power supply the module still does not power on. 

Do you know what we could do ? Or what the problem might be? 

The view angle of the MD4-5 with part number 20085164 is a -70” till 70” view angle.

But in the upper angle about 25”-60”  the display is not clear or readable. We have mounted the display vertically, and because of different heights the option flip is for us not a solution. 

When we sent an application to the display the blue screen is clear, no read problems, how is this possible.

We are really dissappointed about the touch screen changes of the MD4-5 between the 20085164 and the older 200777773

Kind regards,

Laura

Hello,

we got some issue with a MD4 display where the clock reset all the time, we think that it could be some faulty components inside.

have you heard about similar issue

MD4-5 M19 version, having issues with the touch panel. Noticed that the problem is more pronounced when using smaller buttons on screen. By using larger touch buttons the issue seems to be improved but not perfect. The screen responds to the press (it goes orange) but does not actually process the command to exit the screen. Seems very temperamental. Is there a built in delay to prevent button bounce that could be causing this phenomenon? We also tried without the screen protector and had similar issues. I tried without filming and was pressing the screen very firmly and around 6 times before it would register the button press (sometimes it went orange and did nothing, other times it did not even change colour).

IQAN Design 5.06.

Hello all, 

I am trying to do speed control of a BLDC motor with a Parker MD4. I have a quadrature encoder for the motor and would like to know how to calculate the speed for the motor using the IQAN Design software. I can calculate the position of the motor from the sensor, but to estimate the speed in rpm, I need to perform differentiation of the position data. I wanted to know if there is a channel/library/block that will give speed outputs or will do differentiation? Or should I write my own Qcode for differentiation?. 

When using the MD4-5 in portrait mode are the large C1 & C2 connectors at the top or bottom of the module?

has anyone experience this issue before, got an MD4-5, it will not go pass the start up screen with the parker logo on it.

have load a new blank app to try and reset it, but issue remains. any ideas

For future projects I need a touchscreen display with a size of 12 ".

Is something planned in this size?
