DIP Switch S1 and S2
Address dialing S1+S2:
Address dialing is required when using the centralized controller.
Network address:
• The address silkscreen is NET address, which is composed of a 16-
bit address rotary code S2 plus a two-digit DIP switch S1 (Set during
engineering installation, no network function needs to be set)
• When S2 is 00 (the dialing code is not connected), the network
address value is S2
• When S2 is 10 (corresponding to the switch of the hardware con-
nected to the 10K resistor), the network address value is S2 plus 32
• Determined by dial code S2 1-10K 2-5.1K. When S2 is 01
(corresponding to the dial code of the 5.1K resistor connected to the
hardware is turned on), the network address value is S2 plus 16
• When S2 is 11 (all dialing codes are on), the network address value
is S2 plus 48.
NOTE: The SW4 DIP switch is for certied service technician use only.
