Model 2071 is steered by serial signal RS232 or RS485. You may select red or green 6-digit display. Serial bus is galvanic isolated from both processor and power supply. In configuration stage you can set address, Baud rate and what display shows without steering when power supply is connected.
RS232 signal allows only one device to serial port, max. distance 20 m. RS485 signal is reliable up to 1000 m. You may connect to one bus 32 addressable meters. Check sum is added to Nokeval SCLcommunication
