Wiring the Card Reader Inputs
Be sure you wire all card readers with shielded wiring.
The maximum length of wire you may use depends on the card reader
brand name and the type of wiring/cable you use. Refer to the earlier
sections in this manual.
In the case of Proximity card readers, you may connect the required
12 VDC power supply at the ACX 780/781 or at the card reader.
