#188156 - tethered unit??
Responding to: David Brown's previous message
There will be an electrical room ~50 feet from the display. That is where the RS485 is going, and where the power for the display is coming from.
it sounds like you are making a tethered unit, so the operator is going to drag ~50 feet of cable around with him ?

that gives a new definition of 'user friendly'

I would use a (rechageable) beattery and bluetooth/Zigbee/flash store and USB/....
