The large field display series 1000 for serial communication is designed for applications where a readability of 20 to 100 metres is required. Configuration is easy with keys and a 4 digit minidisplay inside the case. The displays use the simple Nokeval SCL protocol where only the address, value and check sum are sent. The displays come standard with both the serial inputs RS-232 and RS- 485. The serial bus is galvanically isolated from the processor and the power supply. In the configuration mode you can set the address, baud rate and the type of number value that you want to appear on the display after power connection.
