MCP2120 Dev Board (ASCII)
This is the typical mode that will be used for the two MCP2120 Developer鈥檚
Board. In this configuration, the MCP2120 board receives data as a single
ASCII byte. This byte is then translated to the IR data format, and transmitted
out of the selected optical transceiver logic.
The host interface can be from either the DB-9 (PC or other UART) or the
Header.
A PC running a terminal emulation program, such as Hyperterminal,
connected to the serial port will create this ASCII data stream. The PC can
then be connected to the Developer鈥檚 Board DB-9 connector.

Configuration 2
Developer鈥檚 Board #1
Developer鈥檚 Board #2
MCP2120 Dev Board (IR Driver)

MCP2120 Dev Board (IR Driver)
This is used to view the effects of the IrDA standard stack protocol on the data
stream. This can be used to better understand the construction of the IrDA
standard data packet, or as a diagnostic tool.
The host interface can be from either the DB-9 (PC or other UART) or the
Header.
A PC running a terminal emulation program, such as Hyperterminal,
connected to the IR port as a virtual serial port will create this ASCII data
stream. The PC can then be connected to the MCP2120 Developer鈥檚 Board
DB-9 connector.

Configuration 3
Developer鈥檚 Board #1
Developer鈥檚 Board #2
MCP2150 Dev Board (ASCII)
鈫?/div>
MCP2120 Dev Board (IR Driver)
This is the configuration when using one MCP2120 Developer鈥檚 Board and
one MCP2150 Developer鈥檚 Board.
The MCP2150 Developer鈥檚 Board can have the host interface be from either
the DB-9 (PC or other UART) or the Header.
The MCP2120 Developer鈥檚 Board would interface to a PC running a terminal
emulation program, such as Hyperterminal, that connects the IR port to a
virtual serial port.
