The touchscreen comprises a
laminated glass sensor, which encompasses the sensing medium, and
the control card that connects to the communications port of the
computer.
Detection Method:
Dynamic capacitance using horizontal and vertical 10 micron diameter
wires.
Power Requirements:
Typically 5mA at 6 to 12 volts which is provided by RS232 port, USB
or external source.
Lead and Connector:
Female D9 serial connector on a 3 metre long, 3 wire, lead. Maximum
length of lead – 10 metres. Power supply components in connections
– 2 diodes, 1 resistor and 1 capacitor.
Operating Temperature:
-35°C to +65°C
