* A 10 Pin Ribbon Cable is the most
convenient way to wire the BD4. You
can build your own ribbon cables or you
can use the Digitrax Signal Driver Cable
Kit (Part # SDCK). Alternately, you can
wire directly to the pins on either or both
of the headers. The header pin arrangement is:

Note: All detection sections from each
BD4 must be powered by the same
booster. (They must all be in the same
power district.)
Pin 10 must bemust be connected to system
ground such as the AX1 terminal of
the DS64, Ground on the
booster terminal, etc.

BD4 Wiring Diagram
See www.digitrax.com for additional information a out BD4, DS64 and SE8 series decoders. The BD4’s sensitivity can e decreased y connecting a 1/4 watt resistor in the range of 47ohms to1 Kohm from the DS (detection section) screw terminal to the Rail A screw terminal on the screw connector on the BD4. Each DS 1-4 can e adjusted separately.
