Connecting to a Computer Using the RS-232C Interface
16.2.3.
Features
The balance is of the DCE type (Data Communication Equipment), which can be connected to a
personal computer using the RS-232C interface. Before connection, read the personal computer
manual thoroughly. Use a standard DCE cable for connection (cable type: straight-through).
Using Windows Communication Tools Software (WinCT)
When Windows is used as an operating system in a personal computer, the WinCT software can
be used to transmit the weighing data to the personal computer. The current version of the WinCT
can be downloaded from the A&D website. Confirm the windows version supported by this
software when downloading. Refer to the WinCT instruction manual in the A&D website. The
WinCT software has three communication methods: "RsCom" , "RsKey" and "RsWeight".
RsCom
RsCom can transmit commands to control the balance.
RsCom can make bi-directional communication between the balance and a personal computer
using the RS-232C interface.
RsCom can display or store the data using a text file format. RsCom can also print the data using
a printer connected to the personal computer.
When several ports of a personal computer have balances connected, the personal computer can
communicate with each balance simultaneously.
RsCom can share a personal computer with other application software.
RsCom can receive the balance GLP report.
RsKey
RsKey can transmit the weighing data output from the balance directly to other application
software such as Microsoft Excel.
RsKey can be used with most application software.
RsKey can receive the balance GLP report.
RsWeight
Can retrieve the weight data from the balance and display the data as a graph in real time.
Can calculate and display the maximum, minimum, average, standard deviation and coefficient of
variation.
Using the WinCT software, the balance can do the following:
Analyzing the weighing data and the statistics input by "RsKey"
The weighing data can be input directly into an Excel worksheet. Then, Excel can analyze the data to
obtain total, average, standard deviation, maximum and minimum values, and display them in a graph.
Controlling the balance using commands from a personal computer
By using "RsCom", the personal computer sends commands such as "re-zero" or "send weighing
data" to the balance and controls the balance.
Printing the balance GLP report using your printer
The balance GLP report can be printed using a printer connected to the personal computer.
Receiving weighing data at a certain interval
The weighing data can be received at a certain interval and data characteristic with elapsed time
can be obtained.
Using the balance memory function
The data can be stored in the balance's memory. Of the data stored, the weighing data and
calibration data can be transmitted to a personal computer at one time.
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.)
