Place the two MCP2120/22 Developer’s Boards on a flat
surface about 25 cm (10 inches) apart, and with the IR
ports facing each other.
On the MCP2120/22 Developer’s Board #1:
Ensure that the jumpers are configured as in
Figure 2-2
On the MCP2120/22 Developer’s Board #2:
Ensure that the jumpers are configured as in
Figure 2-4
and can be left open.
On the MCP2120/22 Developer’s Boards:
Apply power to each unit via the USB connector.
Connect PC’s Serial Ports to the DB-9 connector of each
MCP2120/22 Developer’s Board.
On the PC:
Open an instance of HyperTerminal program window
attached to the PC’s Serial Port (such as COM 1) to
connect to the MCP2120/22 Developer’s Board #1.
Ensure that the window indicates that the HyperTerminal
program is connected and properly configured.
On the PC:
In the HyperTerminal program window (COM 1), type
some alpha characters, such as “kLwtGh”.
Continue typing any alpha characters (upper or lower
case)
Note:

On the MCP2120/22 Developer’s Boards:
The green power LED (D1) will turn on.

On the PC:
The HyperTerminal window will indicate
“connected” and the selected Baud rate settings.
On the PC:
The HyperTerminal program window will display
each character and its switched case version. So
“kLwtGh” will show “kKLlwWtTGghH”
The alpha character typed and its opposite case will
be displayed (such as “aA”, “Aa”, “Bb”,...)
