Weighbridge and COM port

Connect the weighing indicator so live weight appears on the Token page.

The indicator sends the weight to the computer through a serial (COM) port or a USB-to-serial adapter. Open Administration → Weighbridge and COM port.

Choose the port, then check Live status.

#Steps

  1. Connect the indicator to the computer. If you use a USB adapter, plug it in.
  2. Open the page and press Rescan. Each port is listed with its description (for example USB Serial Port (COM3)) so you can tell which one is the indicator.
  3. Choose the COM Port. Set Baud rate, Data bits, Parity, Stop bits and Flow control to match the indicator's own settings. The common values are 9600, 8, None, One, None.
  4. Set the Frame delimiter and Parser that match your indicator brand (the manual or Mochan Labs will tell you).
  5. Press Test Connection, then Save. Live status should say Connected.

The Recent raw frames panel shows exactly what the indicator is sending. It is the quickest way to see if the settings are right. If you see garbled text, the baud rate or parity is wrong. If you see nothing, check the cable and the port.

Note

Using simulator (no hardware required) is for training and demos only. Turn it off on a real weighbridge.

Tip

Don't have the indicator for a while? Users with the Approve override permission can enter the weight manually (with a reason). See Weigh a vehicle.
