EMX 34 Installation Guide 6
Wiring the EMX 34
The EMX 34 must be connected to an ACX 700/780 family controller, to an AC power
source, and to a Cardkey reader.
Warning
Be sure that all equipment is not receiving electrical power while you are wiring the controller, or
you could receive an electrical shock that is life-threatening.
Warning
Be sure that wiring and installations comply with local, state, and national electrical codes.
Refer to the figure of the printed circuit board.
The EMX 34 printed circuit board has four inputs (P2, P4, P6, P8) and four outputs (P3,
P5, P7, P9). The inputs from the Cardkey reader are wired on the right-hand side of the
physical board, and the outputs on the left-hand side.

Channel 3
(same as above)
The schematic to the right represents the data
conversion action of the EMX 34. Data flows
from the Cardkey reader to the ACX 700/780,
and is converted into Wiegand format. The Cardkey
reader’s lamps are switched ON or OFF as a function
of the status of the ACX controller’s LEDs.
The same wiring schematic applies to each of the
four channels.
Note: In this schematic, data conversion is
represented from left to right, which is not
the same direction as the physical board.
