  • Configuring DT8x Data Loggers to Interface with Maple Displays via Modbus
    and DT85 models support Modbus communication via either the serial sensor port on the front of the logger (1Serial) which allows RS-232, RS-485 or RS-422 communications or the host serial port on the side of the logger (2Serial) which is RS-232 only. When using the front serial port, a custom cable
