14-3 Using Windows Communication Tools (WinCT)
When Windows is used as an operating system in a personal computer, the WinCT software, that is
downloaded from the A&D website, can be used to transmit the weight data to the personal computer.
The WinCT has two communication methods: “RsCom” and “RsKey”.
RsCom
Can transmit commands to control the balance.
Can make bi-directional communication between the balance and a personal computer using the
RS-232C serial interface.
Can display or store the data using a text file format. Can also print the data using a printer connected
to the personal computer.
When several ports of a personal computer have balances connected, can communicate with each
balance simultaneously.
Can share a personal computer with other application software.
RsKey
Can transmit the weight data output from the balance directly to other application software such as
Microsoft Excel.
Can be used with most application software.
Using the WinCT software, the balance can do the following:
1 Analyzing the weight data and the statistics with “RsKey”
The weight data can be input directly into an Excel worksheet. Then, Excel can analyze the data to
obtain sum, average, standard deviation, maximum and minimum value, and display them in a graph.
2 Controlling the balance using commands from a personal computer
By using “RsCom”, the personal computer sends commands such as “re-zero” or “send weight data”
to the balance and controls the balance.
3 Printing the balance GLP report using your printer
The balance GLP report can be printed using a printer connected to the personal computer.
4 Receiving weight data at a certain interval
The weight data can be received at a certain interval and data characteristic with elapsed time can be
obtained.
5 Using a personal computer as an external indicator
With the “RsKey” test mode function, a personal computer can be used as an external weight
indicator for the balance. (To do this, set the balance data output mode to stream mode.)
