Connecting MP3200 through IrDA

The MP3200(BT) is equipped with a standard IrDA interface.

IrDA is an industry standard defined by the IrDA consortium

(Infrared Data Association). It specifies a way to transfer data

wirelessly via infrared radiation. The IrDA specifications include

standards for both the physical devices and the protocols they

use to communicate with each other.

Especially, the most popular IrOBEX and IrCOMM protocols are

supported by the MP3200(BT). This allows MP3200(BT) to be

compatible with most IrDA-enabled computing platforms, such

as PC, laptop, PDA, PDT and mobile phone, etc.

IrOBEX stands for Infrared OBject EXchange and is an industry

standard of the IrDA, which defines how “Objects” can be shared

between different IrDA devices. The IrOBEX protocol has been

built into the Microsoft Windows system and is supported by

many various devices.

IrCOMM stands for Infrared COMMunications, which supports

the legacy applications by emulating the RS232 serial port over

the IrLMP/IrLAP protocol stack. Please note that the Microsoft

Windows system does not support IrCOMM software driver, you

have to obtain the IrCOMM driver from the third-party.

Before establishing an Infrared connection between MP3200(BT)

and the host system, please decide the IrDA protocol and IrDA

port in advance.

The MP3200(BT) supports both IrOBEX and IrCOMM protocols.

IrOBEX is enabled as the default setting. If you would like to use

IrCOMM, you can use the printer command to change the

default setting.

There are two IrDA ports available for communication. Port1 is

on the upper side of the body, port2 is on the back side of the

body. Both ports are enabled as the default setting. But

sometimes the data might not be received correctly when

transmission is in interruptive condition. If you wish to get a more

reliable transmission, you are recommended to choose only the

convenient one for your applications. You can use the printer

command to change the default setting.

Port 1

Please refer to the Programming Reference for changing

the IrDA protocol and IrDA port.
