Installation Instructions
USB
Digital Audio &
Analog Audio Out
12 Volts DC
The left connector has analog audio on standard 1/8"
(3.5mm) jack. A cable is provided. Also available on this
same jack is optical digital audio; an adaptor is provided to
allow use of standard Toslink cables.
The center connector is the power supply for the tuner.
Center pin is positive.
The right connector is USB.
When the suspend signal is sent from the computer, the tuner
will power off, and draw very little current, this is to prevent
battery drain.
Supplied is a coax dc power plug. Use this in a CarPC environment. Again, center
pin is the positive. Solder on 2 wires and connect center pin to 12VDC constant
(yellow on standard PC power supplies). And the outer is of course ground (black
on standard pc supplies).
