Connection to a computer using the USB Interface
Features
The weighing data can be transmitted to a personal computer when connecting the balance and
personal computer by the USB interface. The operation system must be Windows 98 or a later version.
The USB interface uses standard device driver software and does not require installation of
special driver software. When simply using the USB interface and cable, weighing data can be
transmitted.
The data can be transmitted to most application software (ex.: EXCEL, WORD, note pad).
Cautions
The balance can transmit the weighing data without the header and unit.
The USB Interface of the balance can not receive the command that controls the balance.
When using the command, connect to the RS-232C interface of the balance. When
connecting the USB Interface of a personal computer to the RS-232C interface of the
balance, use the USB converter (AX-USB-9P).
Do not use the screensaver or suspend mode of a personal computer.
Using the USB Interface
1 Start the Windows of the personal computer.
Connect the AC adaptor to the balance and turn on the display with the
ON:OFF
key.
2 Connect the personal computer to the balance using the USB cable.
Note: Do not use stream mode of data output mode (
dout, prt 3
).
3 At the first connection only, the USB driver software is automatically installed.
4 Open the application (ex.: EXCEL) that is to receive the weighing data.
Move the cursor onto the position to input the weighing data.
5 Press
the
key to input the weighing data at the position of the cursor.
6 When finishing the operation, remove the USB cable.
