Figure 4.  4009 IDNet System Board 
Software Address/Configuration DIP Switch SW2 
The Software Address/Configuration Switch (SW2) is an 8-position DIP switch.  
T
he Software Configuration/Address Switch is located at the top edge of the 
system board.  When the 4009 IDNet is operating as a addressable IDNet 
peripheral, this switch sets the IDNet address to which the 4009 IDNet responds. 
Each 4009 IDNet has a unique address (1 through 250).  The address of the 4009 
IDNet is set via the eight-position dip switch SW2, DIP switch position 1 is the 
least significant bit (LSB) and position 8 is the most significant bit (MSB).  Set 
the 4009 IDNet address using Figure 5 as reference.  Use a small screwdriver or 
pen to set the switches.
