    How to troubleshoot WindowsDirect communication not operating on Shimadzu ATX224?
    • J
      Jordan MendozaAug 13, 2025
      If WindowsDirect communication for your Shimadzu Scales isn't working, first check the communication cable (whether it's a Shimadzu authorized part or a general market alternative) and its connection. If you're using a USB serial converter, ensure it's set to a COM port number between COM1 and COM4, as higher numbers might not be compatible. Also, the driver for the USB serial converter may need to be reinstalled. Some notebooks have a setting to disable RS-232C ports to save power; make sure this setting is enabled. Finally, LAN communications might interfere with serial key device settings, so try using WindowsDirect communication without the LAN.

      When inputting data into Excel from Shimadzu Scales, and the cursor doesn't move to another cell, first turn off any function for conversion to 2-byte characters in Windows. Next, in Excel, go to [Options], then the [Edit] tab, and ensure that [Move selection after Enter] is checked. If cells move correctly with keyboard input, there's no issue. You can also check the input data in another application like Notepad.

    Why is the operation sometimes abnormal on Shimadzu ATX224?

      If your Shimadzu Scales are sometimes operating abnormally, it could be due to the PC's processing capability. Try setting the communication speed to 300 bps. Malfunctions can also occur if the data transmission interval is too short, so ensure each data batch is displayed before the next one is sent. Avoid using the continuous output function if there's limited processing capability. Also, refrain from using the PC's keyboard or mouse while data is being sent from the balance.

      Melanie BakerAug 25, 2025
      If data is input to your PC as garbled characters from Shimadzu Scales, it's possible that either the balance or the PC isn't correctly set for the WindowsDirect connection function. Please refer to "Setting the Function" on page 105 to reconfigure these settings.

      If WindowsDirect communication is not working, verify the communication cable (use a Shimadzu authorized part or another part available on the general market) and check the connection. If using a USB serial converter, ensure it's set to COM1 to COM4. Reinstall the USB serial converter driver if necessary. Also, ensure RS-232C ports are enabled in your PC's power settings. Finally, try disabling LAN communications to avoid interference with serial key device settings.

      If the operation is sometimes abnormal, try setting the communication speed to 300 bps. Ensure that one batch of data is displayed before the next is sent, and avoid using the continuous output function if there are processing limitations. Also, refrain from using the PC's keyboard or mouse while data is being sent from the balance.
