Hello Zafar, I'm not using MDI that much but when you need something to type in it is not that inconvenient. At the begining I first plan to mount keyboard just below LCD but then I've changed my mind because I'm using control panel more often. Regarding pendant box I ordered it from RS Components.

Hello Dave, that blue LCD is from the computer. It's showing CPU temperature and some other things. Keyboard is TRUST, here is link http://www.trust.com/products/productpictures.aspx?artnr=16705
