equivalent (configured for 9600 baud 8,1,N). Trailers, headers, and badge number processing are
configurable through the programming interface. Refer to the WDG-5912 programming manual for
detailed programming instructions. The WDG-5912 will work with most host computers that support a
USB keyboard interface.

Ground is connected to
Reader and Wedge.
Power (+VDC) is connected
to reader ONLY.
External power should not
be applied to +5 VDC

(+)
(-)
An external power supply may be required for applications where the
combined current requirements of the wedge and reader exceed the
capacity of the USB interface. A power supply will also be required
for readers that specify more than 5 volts supply voltage (i.e. 12VDC)
