The objective was to realize converter, which provide communication between precision balance firmy Vibra and recorder firmy LUMEL.

To do this:

  • hardware converter RS-232 standard to RS-485 standard;
  • software implementation converter from ASCII format to compatibile with Modbus RTU protocol.

Precision balance sends data in ASCII format (RS-232 standard) to converter, and converter sends them to the recorder compatibile with the MODBUS RTU protocol (RS-485 standard). Transferred data from precision balance to recorder allows read weight with accurate to 2 decimal places.
