2.1 BHT System Configuration
The BHT barcode data collection system requires the following hardware as well as the BHT Barcode
Handy Terminal (which reads barcodes and accepts keypad entry), depending upon the intended
system configuration.
• Host computer: Allows you to edit, manage and download user programs and
data, as well as downloading system programs.
For host computers having no IrDA interface ports, the optional CU-400 optical communication unit and
RS-232C interface cable (for CU-401) or USB cable (for CU-421) are available.
• CU-400 (option): Exchanges programs and data with the BHT via the IrDA interface
and with the host computer via the RS-232C (CU-401) or USB
(CU-421) interface.
• RS-232C interface cable (option): Connects the CU-401 and the host computer.
• USB interface cable (option): Connects the CU-421 and the host computer.
Connector interface cable/USB cable connection between the BHT and host computer is also possible.
As an application development tool, Microsoft eMbedded Visual C++ (Service Pack 4 or later), Microsoft
Visual Studio .NET or Microsoft Visual Studio .NET 2003 should be used.
