The table above shows how to set the address of the videophone. Considering that ON = 1 and OFF = 0, multiply each digit for the relevant decimal
weight then sum values obtained to get the address: E.g. as highlighted in the table OFF,ON,OFF,OFF,ON, OFF,ON in binary is equal to 0100101 then
multiplying each digit for the relevant decimal weight you obtain the address that is 37.
Note
The maximum number of units allowed is 64 but the address of each unit can be a value between 1 and 99
