Getting Started

2.4.4.

Configuration 4

This configuration is used to evaluate the MCP2120 for an IrDA system,

where the Host Controller is responsible for the IrDA protocol stack.

The MCP2120 Developer’s Board interfaces to a PC running a terminal

emulation program, such as Hyperterminal, that connects the IR port to a

virtual serial port.

2.4.5.

Configuration 5

This configuration is used to evaluate the MCP2150 for adding the IrDA

feature to a system. The Host controller only needs to send and receive the

required ASCII data, while the MCP2150 handles the IrDA standard protocol

stack.

The MCP2150 Developer’s Board can have the host interface be from either

the DB-9 (PC or other UART) or the Header.
