If the Microchip AR1100 Touch Screen Controller Board is installed into a monitor appli-
cation where the end user will decide to use USB communication or RS-232 commu-
nication, the board must be powered internally. Because the board cannot be supplied
with power from USB and internal 5V, it is recommended that the power (pin 1) contact
be removed from the USB socket to insure that multiple power source connections are
not permitted.
SUPPLYING POWER FROM TWO DIFFERENT POWER SOURCES COULD
PERMANENTLY DAMAGE YOUR CONTROLLER, YOUR COMPUTER, AND/OR
YOUR MONITOR.
