When you select either RS-232C or RS-485 to a communication interface, you will find "UNI-Format" as one of the options. By transmitting commands from a host, not only communicating weight values and/or parameters, but also continuous transmission can be operated. This communication format can be used easily on a terminal software on PC. By transmitting a command to an ID specified by a host (on PC side), the corresponding indicator sends back a response.
