Using The (Db9) Rs-232 Connector For Mouse Control Or Data - AMX 10.4 TOUCH PANELS (G3 FIRMWARE) Instruction Manual

Never connect both power wires from the power supply and Central Controller to the
PWR terminal on the touch panel AXlink connector. Only the power supply's PWR
wire should be connected to the touch panel AXlink connector. If both sources are
used to provide power to the touch panel, an electrical hazard is created and the
threat of both equipment damage and injury is likely.
4. Place the PWR wire from the power supply into the open clamp position for PWR on the touch
panel AXlink connector.

Using the (DB9) RS-232 connector for mouse control or data

The dual-function (DB9) RS-232 connector supports most standard serial mouse control devices
and RS-232 communication protocols for PC data transmission.
The following table lists (DB9) RS-232 connector pinouts and FIG. 9 shows the (DB9) RS-232
connector and power supply wiring diagram.
