Virtual COM mode
Virtual COM mode is a function where a balance connected to a personal computer with the included
USB cable, creates a COM port on the personal computer and performs bidirectional communication.
The supported OS is Windows 7 or later. When using the mode for the first time on a personal computer
running anything other than Windows 10, it is necessary to install the dedicated driver on the personal
computer.
For details on installation of the USB interface "Virtual COM mode" driver for the GX-A/GF-A series,
refer to our website (http://www.aandd.jp).
Communication equivalent to RS-232C is possible by selecting the COM port with WinCT (Windows
Communication Tools Software).
In Virtual COM mode, it is not necessary to set the baud rate, data bit, parity, or stop bit of the data
communication software.
Caution
When installing the driver for Virtual COM mode for the first time, it may take some time to install.
Setting procedure
To use the Virtual COM mode, set [Virtual Com mode] in the function table of the balance.
