Just wondering if anyone knows the font style the dlts used
The font used in DLT is not a standard font. It was selected uniquely for the DLT to suit the screen resolution and provide good readability from a distance and at angles.
If JJE was asking so that you could create "images" of DLTs, then there is a cool little tool http://www2.clipsal.com/cis/technical/downloads/commissioning_tools#Dltsimulator
