2.
Connect a wire from a clean chassis ground point to
the last (GND) terminal on the power connector.
Tighten the setscrew to secure the wire in place.
NOTE: Keep the length of the Ground wire (GND) as
short as possible.
3.
Insert a wire into the middle (REM) terminal on
the power connector and tighten the setscrew to
secure the wire in place.
Used as an input: Connect the other end of the
REM wire to a switched 12 volt positive source.The
switched voltage is usually taken from the source
unit's remote amp on lead.
Used as an output: This feature only functions if
the Line Driver is connected to the source unit
using the HIGH LEVEL inputs. Connect the other
end of the REM wire to the Remote ON input of
an external device, such as an amplifier.We
recommend using this feature only if the vehicle
source unit does not have a remote output to turn
on external devices.
IMPORTANT:
When used, the remote out is current
limited.We recommend using a relay if
you need to remotely turn on more
than two (2) other devices.
