15. Data Communication

The following communication interfaces can be used for communication with the host computer. Of the three listed

below, the IrDA interface and connector interface can be used with the CommSerial class and FileTransfer class in

order to create applications.

• IrDA interface (IrDA-SIR1.2)

• Connector interface

• USB interface

15.1. IrDA Interface

The IrDA interface is assigned to port no. 4.

Communication

Parameter

Setting Default

Transmission

speed (bps)

115200, 57600, 38400, 19200, 9600 9600

The IrDA interface conforms to an IrDA physical layer (IrDA-SIR1.2), and therefore parameters other than

transmission speed are all fixed (vertical parity = none, character length = 8 bits, stop bit length = 1 bit).

15.2. Connector Interface

The connector interface is assigned to port no. 1.

Communication

Parameter

Setting Default

Transmission

speed (bps)

115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200, 600, 300 9600

Vertical parity None, even number, odd number None

Data length 7 bits, 8 bits 8

Stop bit length 1 bit, 2 bits 1

15.3. File Transfer

The FileTransfer class can be used to create a file transfer application using Y-modem communication.

In addition to the file itself, the “filename” and “file update date” are also transferred. If, however, the application at

the computer side is not compatible with the file update date, the transfer time will be set for both uploading and

downloading.

15.4. ActiveSync Auto Connection

The ActiveSync auto connection function can be enabled or disabled from the application.

This can be set for each communication interface.

The default value for all communication interfaces is “Disabled”.

The CU-421 is required for ActiveSync auto connection using IrDA.
