Quick Question:

I\'m looking through the pin-outs for the RS-232 connector on the HDC2450, and I see pins 2 and 3 are for TxData and RxData, respectively. If anyone knows, what are these pins for and what are they typically connected to (if anything)?

These are RS232 communication pin. You would connect these to your PC COM port if one is available. Otherwise you can use a USB to serial adapter.

You do not need to use them if you connect the controller to the PC directly through the USB connector.
