Sense, Credit & Tilt
Output Information
Electrical Characteristics
These signals are all open
collector transistors with pull-up or pull-down resistors as specified
in the table below. The specific signals available depend on your
selection of Personality Plug, which adapts
available these signals to the requirements of the electrical
connector specifications for different machines.

Output Signal Logic
The table below specifies the
expected output signals under different conditions. Firmware versions
prior to those listed in the table do not produce the signals marked
by the asterisk (*). See also next paragraph which describes
additional conditions that trigger a Tilt output.

Tilt Timer, Tilt Output, & Self
Inhibit
The Tilt Timer and Self Inhibit
functions are activated by any of the following: 1.) slow or struck
coin, 2.) reverse direction coin, 3.)
BadCoinCount Defense, or 4.)
other system function problem. The purpose of this defense is to
reject anything a perpetrator does for a short period of time once he
has triggered the timer. In this way, if he once fails for an instant
at doing his stunt perfectly, the unit trip into Self Inhibit until
the Tilt Time has expired. For any activity detected during this
period, the Tilt Timer will be set back up to the full Tilt Time value
so that continued attempts are always rejected. The Tilt Time value is
set using the P command of the Serial Port
Protocol. Typically about 1 to 2 seconds (factory default TiltTime
= 4 = 1.333sec) is recommended for best performance. By the time the
perpetrator leaves, the Self Inhibit TiltTime will have expired and
the Xeptor will be ready to accept coins again from an honest
customer. Electrical specifications for the Tilt Output can be found
on the Personality Plug page.
There are some
special rules/features associated with the Tilt Output that may impact
your choice of setting depending on the needs of the machine receiving
the signal. These rules are as follows.
| Tilt Time = Odd |
Tilt Output will pulse 6 times per second
for duration of Tilt Time. |
| Tilt Time = Even |
Tilt Output will remain on solid for
duration of Tilt Time. |
| No Credit Optics |
Tilt Output will comes on for BadCoinCount Defense |
| Credit Optics Installed |
Tilt Output will not come on for
BadCoinCount Defense |
| Tilt Time > BF |
If the Tilt Output is triggered by a reverse or
slow coin, but not by BadCoinCount Defense the Tilt Output will
latch on until the power to the Xeptor is cycled. This is
available starting with version 3.0r firmware. |
Pulse Timing
Information For OEM's
Pulse Duration Tolerance: The
internal timing of the Xeptor limits resolution to 1.333ms intervals,
thus all output pulses are actually the nearest multiple of 1.333ms.
For example, a 21ms pulse will actually be 21.333ms typical. When
coins are being fast-fed, the internal timing mark for the 1.333ms
interval may be delayed by other important sensor reading activities
for a following coin and there is some small (<1%) probability that
the /Sense or /Credit pulse may be as much as +/- 1ms in error of the
typical value in this circumstance.
Pulse Spacing: The spacing between
/Sense pulses or /Credit pulses will be no less than the width of the
pulse itself. So, even if the coins are flying fast and happen to be
nearly edge to edge, pulses will never run together, but as they are
queued up, will take as long as necessary to serially send them out
per the selected pulse timing (and minimum pulse spacing).
/Sense And /Credit Timing Relationship:
The /Sense pulse starts when the
validity of the coin is known. This happens when the leading edge of
the coin is approximately half way through the Xeptor. The /Credit
pulse starts when the trailing edge of the coin cleared the bottom
built-in credit sensor just below the gate relay. These pulse events
are driven by positional triggers and are not affected by coin speed
or pulse duration. How the /Credit and /Sense pulses relate to one
another in terms of overlap will depend on the actual coin speed and
the pulse durations selected. (Note: As noted in the chart above, even
Xeptors without internal Credit Optics will produce a /Credit pulse,
however its positional trigger is when the trailing edge of the coin
is about in the center of the Xeptor. Obviously, without the installed
Credit Optics, this is the last it sees of the coin, and does not
guarantee that it successfully went past the gate relay rake.)
Multiple Pulse Coins:
When a coin is defined as having a Value of N, then it will
produce N /Sense pulses and N /Credit pulses, each pulse train
starting as described in the paragraph above. If the interest for
using this feature is tokenization or accepting multi-denominational
coins, please also review the information found at the following link:
