PROGRAMMING
Before connecting the intercom to the system, it is important to set the intercom address by the 8 way dip-switch on the back of the
unit. All other programming must be made with the intercom connected, powered and in stand-by.
INTERCOM ADDRESS SETUP SW1 PHONE ID
Each device must be addressed in binary (PHONE ID) using the 8 way dipswitches located on the rear of the unit. Each switch cor-
respond to one bit which can have a value 0 (OFF) or 1 (ON). Each bit corresponds to a decimal weight depending on the position:
Switch 1 = decimal 1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64, 8=128. I.E. to set the address 37, put switches 1, 3 and 6 on (1+4+32=37).
