Address DIP switch:
Address dialing S1+S2: When the user uses
the centralized controller, the address
dialing is required.
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 does not
need to be set].
• When S2 is 00 (the dialing code is not
connected), the network address value is
the value of S2.
• 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 the value of S2 plus 16.
• When S2 is 10 (corresponding to the
switch of the hardware connected to the
10K resistor), the network address value
is S2 plus 32.
• When S2 is 11 (all dialing codes are on),
the network address value is the value of
S2 plus 48.
