Site/System Setup Requirem ents
Before yo u ins t all the contr oller, you sho uld map out w here you pla n t o install each int erface. Whe n planning th e s it es , be aware of dim ensions , power requ irements, and
environm ental requ irements.
Dime nsions
The EMX 34 printed circ uit board is app rox imately 6. 125 × 3.625” (160 × 92 m m ).
Power Requirements
The EMX 34 receives power from an ACX 700/780 to supply the Cardkey reader. The EMX
34 requires an additional 24 VAC (1 amp) which powers the Cardkey reader incandescent
lamps (LE D s ). Th e EMX 34 boa rd converts t he power t o 9 VD C output for th e lam ps.
Environmental Requirements
The EMX 34 operates in the same environment as any Infinet controller.

Wiring the EMX 34
The EMX 34 m us t be connect ed to an ACX 700/780 f am ily control ler, t o an AC power
source, and to a Cardk ey reader.
The schematic to th e right repre se nt s th e data
conversion action of the EMX 34. Data flows
from the Cardkey reader to the ACX 700/780,
and is con v erted into W iegand format. The C ardkey
reader ’s lam ps are switc hed ON or OF F as a f unction
of the sta tu s of the AC X controller’s LEDs.
The same wiring sc hematic app lies to each of the
four channels.
Note: In this schematic, data conversion is
represented from lef t to right, which is not
the same direction as t he physica l board.

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 fi gure of the print ed circuit bo ard.
The EMX 34 printed circ uit board has four inputs (P2, P4, P6, P 8) and four ou tp ut s (P3,
P5, P7, P9 ). Th e inputs from t he Cardkey reader are wi red on the righ t -hand side of t he
physical board, and th e outputs on the lef t -hand side.

Wiring the EMX34 to an ACX Controller
1. Locate the Wiegand out puts, alon g t he left-han d s ide of the EM X 34 printed cir cu it
board (P3 , P 5, P7 P9). Each output inclu des five co nnections .
Note that o n t he R EV A board, t he 1 and Ø terminals are la beled incorrectly.

3. Repeat this procedur e f or t he remaining four wires.
Wiring AC Power to the EMX 34
1. Locate the terminal labeled P1 in the upper left-hand corner of the printed circuit board.
2. Connect t he stripped ends of a 24 VAC (±20% ) external power su pply to the
appropr iate terminals and tighte n th e s c rew s.
Should you need to re place the 1 am p s oc k et picofuse, it is located at F1 on th e printed

Wiring the Cardkey Reader to the EMX 34 Interface Board
Each Cardkey input on th e EMX34 takes 6 wi res. Ther e are four inp uts, locate d along th e
right-hand side of the printed circu it board (P2, P4 , P6, and P8).
1. Locate the existing g ray c able on the ba c k sid e of the Card ke y reader. Str ip t he end
