Using the (DB-9) RS-232 connector for mouse control or data
The dual-function (DB-9) RS-232 connector supports most standard serial mouse control devices
and RS-232 communication protocols for PC data transmission.
The following table lists the (DB-9) RS-232 connector pinouts and FIG. 15 shows the (DB-9)
RS-232 connector and power supply wiring diagram.
Use connector pins 2, 3, and 5 for data and ground. For some applications, you may need to strap
pins 7 (request to send) and 8 (clear to send) together, depending on the PC.
