PROGRAMMING
After each programming operation carried out through dip-switches or jumpers it is necessary to temporary disconnect the phone
from the BUS or from the power supply if locally powered for the new settings to take affect.
PROGRAMMING DEVICE ADDRESS - SW1
Switches from 1 to 7 are used for unit address (from 1 to 99 binary coded).
Dip 8 = OFF intercommunication setting
Dip 8 = ON Service buttons setting to activate Art. 2305 devices.
NOTE: During the conversation the buttons 1-4 always activate the relevant service relay Art. 2305.
The table below shows how to set the address of the device. Considering that ON = 1 and OFF = 0, multiply each digit for the rele-
vant decimal weight then sum the 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 100 but the address of each unit can be a value between 1 and 99.
