change the address, it is necessary to delete first the IP
address which is saved in the flash memory.

CONFIGURATION OF THE IP ADDRESS OF THE UNIT
On the back of the unit there are some DIP switches by means of which the IP address can be configured manually.
This address identifies the unit in the network, so each unit must have a unique IP address.
An IP address is represented by means of a 32-bit binary number. The IP addresses are expressed as decimal notation
numbers: the 32 bits of the address are divided into four octets (an octet is a group of 8 bits). Each octet is
represented by A0 to A7 for the first octet, B0 to B7 for the second octet, C0 to C7 for the third octet and D0 to D7 for
the fourth octet.
Each bit can have the value 0 (DIP switch OFF) or 1 (DIP switch ON). In order to obtain the decimal value of the octet,
the decimal values of each bit that is in the ON position must be added up (from the top down: 1, 2, 4, 8, 16, 32, 64
and 128).
