Chapter 11. Data Communication
11.1. Outline
In wired communication between the BHT and host computer, the following interfaces are available:
(1) IrDA interface
(2) Connector interface
(3) USB client interface
(4) USB host interface
11.2. Programming for Data Communication
(1) IrDA interface
The IrDA interface is assigned to port 4.
Communications
parameter
Effective setting Default
Transmission speed (bps) 115200, 57600, 38400, 19200, 9600 115200
Parameters other than the transmission speed are fixed (Parity = None, Character length = 8 bits, Stop
bit length = 1 bit), since the physical layer of the IrDA interface complies with the IrDA-SIR 1.2.
(2) Connector interface
The Connector interface is assigned to port 1.
RTS and CTS signal lines are not supported.

Transmission speed (bps)
115200,57600,38400,19200,9600,
4800,2400,1200,600,300
115200
Parity None, even, or odd None
Character length 7 or 8 bits 8
Stop bit length 1 or 2 bits 1
(3) USB client interface
The USB clinet interface is used for ActiveSync connection.
(4) USB host interface
The USB host interface is used for connection with network via CU-714 and Ethernet cable. When
BHT-700 is set on CU-714, new connection named “AX-887721” is created in Control Panel.
11.3. Assigning Port Number
From COM1 to COM8 are used by system program. Assign 9 or 0 to COM port number of
communication made newly.
