Order - CF9510 Quick Reference Card Rev G2 - 2006
Interfaces
The CF9510 supports two electrical interfaces corresponding
to the 12volt STD212 and the 24volt STD124 standards.
Both interfaces are available simultaneously in the product
and can be accessed via the connectors shown on the front
page, item 3 and item 4 respectively. Apart from power and
the polarity of the all-inhibit signal, the interfaces are similar,
both providing a parallel interface to the host machine.
STS212
STD212 is a 12V, 10-pin dual inline interface. It features a
subset of the connections available in STD124, including the
coin output signals, ER, and the all-inhibit signal. The
individual coin inhibit signals are not part of this interface.
Besides the 12V input power connection, the other salient
difference between the interfaces is the polarity of the all-
Inhibit signal. In STD212, the polarity of the all-inhibit signal is
active high to block all coins.
The signals’ electrical characteristics are the same as in
STD124, except for the all-inhibit signal which needs to be
driven to a logic 0 to enable all channels and a logic 1 to
inhibit all channels.
STS124
STD124 is a 24V dual inline 16-pin interface. It features 6-
open collector outputs and matching inhibit signals, power and
ground, an all-inhibit input signal, and an escrow return output.
The inhibit input signals (INHx) default to their inactive state
when not driven and will default to enable all coins. The INHx
need to be driven high to inhibit coin acceptance. The all-
inhibit (ALLINHB) signal is an active-low input signal that
inhibits all coins when driven low. It is inactive in its default
state.

Multi Pulse Teach
Switch 8
Multi-pulse teach mode is entered by setting switch 8 to the
ON position and turning the unit on. Again, for this operation,
the LED will blink green a number of times followed by one
red blink. The number of green blinks equates to the number
of pulses to be set and can be changed by pressing the reject
lever. The maximum number of pulses that can be set via the
MMI for each coin is 4.
