Handling and ESD Protection
Establishing the Data Connection
When mounting the touch screen and controller, use normal precautions for handling
electrostatic sensitive devices. The EX II controllers have internal protection to ±27 kV
for ESD discharges to the touch screen (not to the controller directly) that may occur
during normal operation of the touch screen. Refer to Appendix A for further
specifications.
The EX II controllers require that an RS-232 serial communication cable be attached to
connector JP1.
You can use a standard 3M Touch Systems RS-232 cable (P/N 7310101) or an equivalent
interconnect. One end of this cable plugs into the RS-232 connector (JP1) on the
controller. The other end, which has a 9-pin D connector, plugs directly into a serial
COM port on your PC. Table 1 describes the interconnections for the 3M Touch Systems
RS-232 cable.
