Pulse length
Pulse length is the minimum time a debit pulse must last in order to be taken
into account by the Vend Station. If it is shorter, the Vend Station sees the
pulse but disregards it as a non-valid pulse. It is not necessary to match the
pulse length setting with the actual length of the debit pulse coming from the
copier. (i.e. Do not set the pulse length to 0.10 if you see that your debit
pulse last 100ms. The Vend Station may miss some pulses. We suggest to
keep it the lowest possible. A value between 0.01 and 0.04 will fit most copi-
ers). This parameter is not visible when the Smart interface is used.
Pulse blind time
The pulse blind time is the interval between pulses. Usually, this parameter
is set at 0. However, some older copiers may suffer from pulse bouncing. Is
so, the Vend Station sees the bouncing and debits a copy for each of the
bounce. If you wish to eliminate this, set a blind time. The Vend Station will
see the bouncing but will not debit for the duration of the blind time. Be
careful not to set a time too long. If the blind time is too long, the Vend Sta-
tion may miss genuine pulses coming in fast on multiple copies. For exam-
ple, an 80-copy minute copier would send a debit pulse every 750 millisec-
onds. If you set a blind time too high, you will miss genuine debit pulse thus
giving out free copies. This parameter is not visible when the Smart inter-
face is used.
Exit delay
The exit delay is the time laps between the moment the customer pushes on
the coin return and the moment the Vend Station actually starts giving
change back. The 02.00 default value will fit most copiers. However, some
copiers send their debit pulse a little bit late in the process thus forcing you
to set an exit delay a little longer. From the moment the customer activates
the coin/card return and the moment change starts coming out, any debit
pulse coming from the copier will be deducted from the change to give back.
This parameter is not visible when the Smart interface is used.
