  • Page 90 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.
  • Page 91 Connecting to a Computer Using the USB Interface 16.2.4. Features The weighing data can be transmitted to a personal computer when connecting the balance and personal computer via the USB interface. The applicable operating system is Windows 7 or later, as of December 2018.

    Commands 16.3. Command List 16.3.1. Note Before transmitting a command, add the terminator that is specified in the “Terminator (Crlf)” parameter of “Serial interface (5if)” in the function table. Commands to query weighing data Cancels the S or SIR command. Requests the weighing data immediately.
  • Page 93 Acknowledge Code and Error Codes 16.3.2. When the " AK, Error code (erCd)" parameter of "Serial interface function (5if)" is set to "on", the balance outputs <AK> code or error code to each command as follows: <AK> (06h) Acknowledge in ASCII code. When the balance receives a command to request data and cannot process it, the balance transmits an error code (EC, Exx).
