FRONT PANEL FEATURES
SELECT BUTTONS
Use to select the functions programmed with the
Function Select Switch on the back of the remote
control. Pressing a button once toggles the pre-
defined function ON (active), and pressing it again
toggles the function OFF (inactive).
SELECT LED INDICATORS
Indicates the state of the corresponding select but-
ton. When the LED is lit, the selected function is ON
(active).
A space is provided next to each indicating LED
for inserting a 1/4" x 7/8" label to identify the
predefined function assigned to each select button.
REAR PANEL FEATURES
PREDEFINED FUNCTION SELECTION SWITCH
This 8-position DIP switch provides 256 unique func-
tions that can be assigned to the DX-SW4 remote.
Refer to the chart on the back page for a list of all
predefined functions currently available.
Each remote control must have the selection switch
set to a unique ID. When the DX8/DX810 is first
turned on, it polls the REMOTE BUS and identifies the
remote controls connected to it by each unique ID.
Many of the predefined functions have two ID ad-
dresses assigned to it to allow two remote controls
to be connected to a DX8 that both control the
same functions.
CONNECTOR (J2)
Connect the wires from the DX8/DX810 REMOTE
BUS directly to this connector. Strip the wire back
about 1/4", insert the wire as far as it will go into
the connector and tighten down the screw with a
small slot-head screwdriver.
Use a high-quality three-conductor shielded cable
to make this connection, such as Belden 8451,
9451, or equivalent.
The connector is wired as follows:

INSTALLING THE DX-RVC
The DX-SW4 can be installed in a single
standard electrical box, or in a double-gang box
along with a second DX-RVC or DX-SW4 remote
control.
CONNECTING MULTIPLE
REMOTE CONTROLS
Up to nine remote controls can
be connected to the DX8/DX810
REMOTE BUS. The maximum
length of the cable depends on the
type of cable used and the number
and type of remote controls used
in the system.
As a general rule, using 22
gauge wire (at 0.014
Ω
/ft. and
34 pF/ft.), one remote can be up
to 3000 feet away, five remotes
can be up to 2500 feet away, and eight remotes
can be up to 500 feet away before transmission
losses become a factor.

USING AN EXTERNAL POWER
SUPPLY
The DX-SW4 is powered by the DX8/DX810
over the data lines. An external power supply
can be used by removing jumpers J3 and J5
from the DX-RVC circuit board, and connecting
a power supply rated at 9 to 16V AC or DC
to the PWR terminal on the connector (J2). A
number of "wall-warts" or bell transformers are
readily available from local electrical supply
houses with output ratings between 9V and
16V. Allow 25mA per remote.
