1.2.2.1 Host PC with On-Board MCP2200 USB-to-UART Converter
The simplest method to use the RNBD451 Add On Board is to connect it to a PC host that supports USB CDC virtual COM (serial) ports using the on-board MCP2200 USB-to-UART Converter. The user can send simple ASCII commands to the RNBD451 module by using a terminal emulator application. In this situation, the PC acts as the host device. In addition to UART, status and other control GPIOs from the RNBD451PE module are also connected to MCP2200 GPIO pins.
The MCP2200 is configured in Reset condition until the USB supply is plugged in.
