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?
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.
(Example picture above is with RAM mount parts, RAM mount parts not included in delivery)
20077778 fits to IQAN-MD4-7
20077779 fits to IQAN-MD4-5
The kits include black countersunk screws for mounting the bracket to the display.
Hole pattern supports mounting of RAM or Southco tilt swivel mount.
Manufactured in black ED-coated steel.
We use the MD4-7 for all our systems. I have one of my customer with a Fairly new(3 years) but rarely used unit for a test bench. He complains and I witness that is touch screen is often not responding. It is mounted on an aluminum test bench. Sometimes if he moves the unit away from the bench it seems to respond better but not always. We tried to ground the unit but it did not improve. Do you think this is an hardware issue or is there mounting issue we need to look at?
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?
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?
Last monday, we did MD4 temperature test. MD4 waited at -33°C for 4 hours in a closed enviroment. After 4 hours, Power on MD4 7" touch panel and We tested digital in, digital out, canbus channel, touch screen. Resault we are fine. We didnt have a problem. My hand just froze when testing :)
The question is if any of you have used a temperature sensor in the analog input of a MD4-7? Was it PTC or NTC? Because in pdf only talks about connect a PTC sensor with a pull-up resistor. Kind regards. Diego.
