The good operation of the ALIEM unit as a Modbus Slave, can be checked by connecting directly
to the Com2 serial port of the data logger using a PC on which a Modbus RTU Master application
is installed. The MDMMB1110.1 model has an RS-485 serial output, therefore, if the PC does not
have a serial port of the same type, you must have an RS-232 / RS-485 converter.
