A description of the demos, including step-by-step instructions are shown in this
section.
2.3.1
In Demo #1, the MCP2150 Developer’s Board will communicate directly to the PC
(or IrDA to serial interface Dongle) data received on the DB-9 port.
This demo shows the MCP2150 converting data between the IR port and the Host
UART port. The Primary Device’s IR packet is decoded and any data is extracted and
Transmitted on the Host UART interface. Data received on the Host UART interface is
formatted into the IR data packet and transmitted to the Primary device.
Figure 2-1 shows the system setup, while Figure 2-2 shows the jumper configuration
for the MCP2150 board. Lastly, Table 2-2 shows the steps for Demo #1 operation.

Demo #1 Operation - Direct IR / UART (DB-9) Mode
Figure 2-3 shows an alternate jumper configuration where the
MCP2150DM is powered via the V
JP2 shunt be removed). Table 2.3.2 does not document this configuration,
but due to its similarities should be easy for the user to implement.
