MCP2200 USB TO RS-232 DEMO BOARD USER’S GUIDE Chapter 2. MCP2200 USB to RS-232 Demo Board 2.1 INTRODUCTION The MCP2200 USB to RS-232 Demo Board is designed to demonstrate the device in a VCP environment, as well as provide a method for I/O configuration development. The MCP2200 USB to RS-232 Demo Board has the following features: • • • • • 2.
MCP2200 USB to RS-232 Demo Board User’s Guide 2.3 OPERATION The board will operate as a USB to RS-232 converter. In addition, the accompanying software can be used to control the I/O and set custom configurations. 2.3.1 USB to RS-232 Operation The board can be connected to a USB host and to an RS-232 port that usually connects to a PC. If the host application software sends a “Set Line Coding” command (sets the UART baud rate), the MCP2200 will automatically change to the correct baud rate.
MCP2200 USB to RS-232 Demo Board Note: Care must be taken when changing the VID or PID because the software will not be able to communicate to the board if there is a mismatch. FIGURE 2-3: 2010 Microchip Technology Inc.
