3.2.1 Card Reader Specifications
The 4300 Swipe Card Reader, and the 4330, 4340, and 4350 Proximity Readers require
shielded cable. The chart below shows the specifications.
3.2.2 Mounting
Mount the 4300 series readers on any flat vertical surface.
Use two #10 bolts to mount the reader. Once the reader is mounted, cover the reader front by
applying the pressure-sensitive dress panel or label.
When mounting the proximity readers, use flat-head screws. Drill a one-quarter inch (0.6 cm)
or larger hole for the cable. Refer to the mounting template included with the reader for loca-
tion of screw holes.
