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 Boards:
Ensure that the jumpers are configured as in
Figure 2-2
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:
Open a second instance of HyperTerminal program
window attached to the PC’s Serial Port (such as
COM 2) to connect to the MCP2120/22 Developer’s
Board #2.
Ensure that the window indicates that the HyperTerminal
program is connected and properly configured.
On the PC:
In one of the HyperTerminal program windows (COM 1),
type some characters.
On the PC:
In the other HyperTerminal program windows (COM 2),
type some characters.
On the PC:
In either HyperTerminal program windows, select the
Transfer pull-down menu and then the Send Text File ...
option. Navigate to the folder that contains the
Transmit File.Txt file and select it. Then click
Open.
On the PC:
Make this file transfer transmitting from the other
HyperTerminal program window.
Continue steps 7, 8, 9, or 10 for as long as desired.
