PMA-1115 PXI monitor and keyboard

Does this have a resistive or capacitive touchscreen? How good is the touch control on it?


Has anyone found any similar alternatives?

The PMA-1115 has a TFT LCD touch screen. You can find out more details here:



I'm afraid that I don't have experience with alternative options to be able to give a fair comparison.

Thanks for the response. The manual tells me nothing about the tocuhscreen technology (resistive or capacitive). Can anyone from NI give me the answer?

Don't buy this product.  It's horrible.  Monitor works okay but I've had two keyboards fail for no particular reason.  That's right, keyboards, those ubiquitous devices that almost never fail.  Price qouted by NI to repair when outside of warranty?... $1,550.00

  it's resistive.

Thanks Sacha.


I had my concerns about the quality of the touch interface- and resistive is notorious as being the poor cousin of capacitive in this application. Not too bothered about the keyboard, but that repair bill- just WOW!

  I get what you mean about appearing to be the poor cousin given the press and the way that phone manufacure has gravitated to one of the capacitive formats over time.

It's not a question of one is blatantly better than the other though - more a use case.

Capacitive has a less accurate (implicitely) response than resistive and requires that human touch, whereas resistive can be used with any proddy stick so in industrial environments where sometimes gloves are required and they can't have that conductive point to most of them, then you have to go resisitve anyway.

Also, contaminants left on a surface can have different effects - obviously particular contaminents can lead to capacitive screens struggling to maintain their calibration. With resistive, it's still pressure. (You should periodically clean the screen either way as part of maintenance).

Thanks again, Sacha. Some interesting info there on the relative strengths of the two technologies. In any case I'm going to reserve further judgement until I (hopefully) get my mitts on a demo version courtesy of Mr Bakehouse.
