Multiplexors,
ALX-2525 , receive control signals and power from the MUX controller, ALX-2530.
The MUX controller sources power from either the ALR-F800 series reader USB Host port, the
ALR-F800 GPIO +12VDC through the DB15 connector or an external power supply. Power source
is determined by jumper inside of the MUX controller.
