A&D Balance GH02 User Manual

							GH-02 USB Interface Instruction Manual 
1. Features 
   The GH-02 USB interface connects a GH series analytical balance to a personal computer and is used to 
transmit the balance weight data to the personal computer via USB. Applicable operating system is Windows 
98 or later. 
   As the Windows standard driver is used to transmit the weight data, complicated installation of a dedicated 
driver is not necessary. 
  The personal computer recognizes the GH-02 interface much like a keyboard, and processes the weight 
data in the same way as values input by key operation. Thus, the balance weight data can be transmitted to 
applications such as Excel, Word and memo pad for Windows. 
Note:  Only weight data can be transmitted. Headers and units can not be transmitted. 
 Time and date, ID number, data number and GLP report are not output. 
 Data transmission from the personal computer to the balance is not available. To control the 
balance by a command, install the RS-232C board and connect the balance and the personal 
computer using the RS-232C cable. 
 Turn off the screen saver or suspend mode of the personal computer.  Windows, Word and Excel are the registered trademarks of the Microsoft Corporation

   2. Installation Procedure
