Figure 19 shows the most common connection circuit of card
collector. OD can be controlled either by ACS controller or by the card
collector directly, that is why connections 1* and 2* are drawn by dotted
lines. This scheme features two readers. The second reader shall be
installed outside the card collector, which is not always aesthetically and
practically acceptable. If installed close to each other, proximity readers
can create mutual interference.
