8.4 Communications Device
8.4.1 Hardware Required for Data Communications
The following hardware is required for communications between the BHT and the host com-
puter:
• Optical communications unit (CU) and its interface cable
or
• Direct-connect interface cable
For the communications specifications, refer to the BHT User's Manual.
Using Ir-Transfer Utility E allows the BHT to directly communicate with the IR port-integrated
host computer or an external IR transceiver. For details about IR port-integrated computers
and external IR transceivers available, refer to the "Ir-Transfer Utility E Guide."
8.4.2 Programming for Data Communications
Setting the Communications Parameters
Use the
OPEN
"COM:"
statement to set the communications parameters.
■
For IrDA interface
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 1.0.
■
For direct-connect interface
* The parity, character length, and stop bit length are fixed to none, 8 bits, and 1 bit, respec-
tively, if the BHT-Ir protocol is selected.
