- 31 -15. Data CommunicationThe following communication interfaces can be used for communication with the host computer. Of the three listedbelow, the IrDA interface and connector interface can be used with the CommSerial class and FileTransfer class inorder to create applications.• IrDA interface (IrDA-SIR1.2)• Connector interface• USB interface15.1. IrDA InterfaceThe IrDA interface is assigned to port no. 4.CommunicationParameter Setting DefaultTransmissionspeed (bps) 115200, 57600, 38400, 19200, 9600 9600The IrDA interface conforms to an IrDA physical layer (IrDA-SIR1.2), and therefore parameters other thantransmission speed are all fixed (vertical parity = none, character length = 8 bits, stop bit length = 1 bit).15.2. Connector InterfaceThe connector interface is assigned to port no. 1.CommunicationParameter Setting DefaultTransmissionspeed (bps) 115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200, 600, 300 9600Vertical parity None, even number, odd number NoneData length 7 bits, 8 bits 8Stop bit length 1 bit, 2 bits 115.3. File TransferThe 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 atthe computer side is not compatible with the file update date, the transfer time will be set for both uploading anddownloading.15.4. ActiveSync Auto ConnectionThe 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.
