Getting Started

2.4 System Configurations

There are five configurations that one would use for initial evaluation of these

two Developer’s Boards. These configurations are:

The Host controller for each board can be either a Personal Computer (PC) or

another system connected to the Host header. The PC operating system (OS)

may be any desired OS that has a terminal emulation program which can

connect to the serial port and can treat the IR port as a virtual serial port. For

our tutorial, we will use the Windows 9x OS.

Developer’s Board #1

Developer’s Board #2

1. MCP2120 Dev Board (ASCII)

↔ MCP2120 Dev Board (ASCII)

2. MCP2120 Dev Board (IR

Driver)

→ MCP2120 Dev Board (IR Driver)

3. MCP2150 Dev Board (ASCII)

↔ MCP2120 Dev Board (IR Driver)

4. MCP2120 Dev Board (IR

Driver)

→ IrDA standard port (Palm™ Pilot,

cell phone, ...)

5. MCP2150 Dev Board (ASCII)

→ IrDA standard port (Palm Pilot,

cell phone, ...)

Note 1: Windows NT® 4.x (and lower) does not support the IrDA standard

functionality. Third Party programs exist, but are not supported or

recommended by Microsoft, so are also not recommended by

Microchip.

2: Windows® 2000 does support the IrDA standard, but does not treat

the IR port as a virtual serial port. This means that you cannot

access the IR port as a serial port. This causes issues with some

terminal emulation programs, such as Hyperterminal. Windows

2000 considers the IrDA port to be a network device. Applications

that can access a network service through a network protocol (i.e.

TCP/IP) can use the MCP2120 Developer’s Board using the appro-

priate Windows 2000 driver.
