Output Timings
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 host machine (i.e. coin mech. might be changed without powering down) the state of this
output should be regularly polled. As long leads are often involved in a coin mechanism
interfaces, it is recommended that the input should be de-bounced in software to avoid
glitches.
