Negative Common Voltage Range
This interface is selected when pin 3 is <2.5V with respect to pin 12. (0V)
Negative Common Outputs:
On: Maximum current = 30mA
O/P saturation voltage (Coin O/P - Opcom) <1.5V
Off: 10 uA maximum
at
27 volts (Coin O/P - OPcom)
Pulse Width: Switched on for between 80 and 120 ms
on acceptance of the appropriate coin.
Binary Coded Output (BCO)
BCO mode is indicated by the A output being permanently active. This indicator can take up
to 100 milliseconds to be established from power up.
In order to ensure reliable operation of the machine the state of this output should be
regularly polled (as the coin validator could be reconfigured without the power being
removed).
As there are often long machine interface leads involved in coin mechanism interfaces, it is
recommended that the coin outputs should be de-bounced in software to reduce the effect
of glitches.
Coin Inhibits
Input voltage to enable channels (logic 0) ) <1.0V
Input voltage to inhibit channels (logic 1)
>4.0V
Input impedance
12 Kohms to +5v.
Output
Common
Output
T(o/p valid) = 15 micro seconds

Outputs
to be Set
o/p off
o/p on
100 ms ± 10%
