INTERFACE OVERVIEW

Terminal Application (USB/RS-232C)

Invoke a terminal application such as RealTerm.

For RS-232C and USB, set the COM port, baud rate, stop bit, data bit, and parity accordingly.

To check the COM port number and associated port settings, see the Device Manager in the PC. For WinXP: Control panel → System → Hardware tab

Example: Configuring RealTerm for RS232C communication.
