If the touchscreen driver is showing "MAC ADDRESS NOT LOCATED"
Make sure the touchscreen is in the AVLinkPro is present under Applications
If not check that the panel is addressable at the IP address it was last addressed at. If not it may need to be re-assigned
to the AVLinkPro.

For the SIPAHOY driver it can lot see the associated touchscreen.
Take the driver out of the room associated with that touchscreen.... then put it back.
Please wait... it will take a second!
