MD4 temperature

AxelC 4 years ago in Master modules / MD4 • updated by Gustav Widén (System support) 12 months ago 3
We are in Thailand where average temperature is 35 degree Celsius.

We have 2 MD4 on 2 project, they are hot when running, internal sensor tell 52 degree Celsius minimum most of the time. It is really hot on the finger, our customers are a little worried.

We also have MD3, they are also at more than 50 degree but we don' t feel it on the buttons.

Does all the MD3/4 get hot like this? Is there recomendation to reduce that?

MD4 10" screen

Richard 3 years ago in Master modules / MD4 0

Does anyone know how the 10" version of the MD4 is coming along. The last information I had was the unit was not released for production yet due to screen fogging issues. I hope that is resolved as I may well have an application for the unit.

Is the unit available for sale?

MD4 user inputs

Richard 4 years ago in Master modules / MD4 • updated 2 years ago 2
I want to use multiple MD4 units on a new project but the problem is in our application the user may be wearing gloves so I am not sure a touch screen is useful. My first idea was to put a CAN open tactile button pad by the side of the MD4 unit but have come up with a blank.
I have tried - Grayhill - Graf-Syteco and powerkey so far who do have keypads but they do not have a size or shape currently in production that fits nicely alongside the MD4 (7").
Does anyone have any ideas?

Speaker

Metalfor 4 years ago in Master modules / MD4 0
Hello. I've found in MD4 displays that the only way to handle sound is with one low side digital output for buzzers. The displays have very good screen definitions, excellent images design tools but need internal speaker to give to end users an auditory experience according to the others senses involved when use Parker's displays. I suppose that the only negative point is the IP degree of display will decrease. Bet regards. Diego.

Digital out channel (DOUT) high frequency buzzer noise?

J Kelly 3 weeks ago in Master modules / MD4 • updated by Steve Liljestrand 2 weeks ago 2

I have connected a buzzer to my MD4-7 inch display using the DOUT channel. 

The signal receives high frequency noise when it is not triggered. Could this be related to the diagnostics tests for internal faults?  - If so how can it be switched off via IQAN design.

MD4 +RTC RESISTOR

Chris Litwin 3 weeks ago in Master modules / MD4 • updated by Gustav Widén (System support) 2 weeks ago 4

The MD4 documentation states to use 1.5K ohm resistor on the +RTC circuit. Is the 1.5K ohm the only type that is usable, or is there a range that will work?

Faulty/broken MD4

L.P.C 6 months ago in Master modules / MD4 • updated by Jean-Marc Zanni 4 weeks ago 5

We have had multiple MD4 units (7 and 10 inches) no longer powering up.

Do you have any idea what could cause that?  We're using fuses to protect the units, but sometimes they still seem to fail on normal operation.
