If Switch 1 = On, Switch 2 = Off, Switch 3 = On, and Switch 4 = Off then the DC4 will respond to
commands sent to addresses B5 through B8. The AquaController must be configured to use the
same addresses as selected on the DC4. Refer to the AquaController Owner’s manual for more
information on how to set up the AquaController.
X-10 Input (X-10 In)
The left RJ-11 connector (telephone plug) is the input connector for the X10 signal. A telephone style
cable (supplied with the DC4HD is used to connect this DC4HD X-10 port to the AquaController.
The length of this cable should be less than 10 feet.
X-10 Output (X-10 Out)
The right RJ-11 connector (telephone plug) is the output connector for the X10 signal. A telephone
style cable (4 internal wires) should be used to connect this X-10 output port to another DC4HD X-
10 input port. Always connect X-10 inputs to X-10 outputs when daisy chaining multiple DC4s
together. The last DC4HD in the chain should either have its X-10 output unconnected or connected
to an X10 power-line interface. The total length of all X-10 cables should be less than 20 feet.
Internal Fuse
Inside the DC4HD there is a fast-blow 15-amp fuse. In the event of an overload or short circuit this
internal fuse will blow.
Only replace with a 15-amp or smaller fuse
. Replacement fuses may be
purchased directly from Neptune Systems.
Always disconnect all power before opening the
DC4HD case, and never apply power when the DC4 case is open.
