1、How about the wiring of coin acceptor and output
Multi-pulse single line outout, Parallel lines output for different
coins, MDB type output, RS232 type outout . In wafer products
series, EU1,EU2 and SK coin acceptor,that is single line output,
and HI-09 has single line output and also the parallel lines
2、What is the output single of coin acceptor What voltage of the
output single of coin acceptor
Normally,coin acceptor output is the Open-C NPN type output,So
there is no voltage output from the output line and that need to be
drived to high voltage through resistance .
MDB Type coin acceptor,that is normally used in the vending machine
system. from example from COINCO and MEI coin validators.
MDB Connector defined as following pictures：
3、What is the NO/NC selection of coin acceptor （Already have drived
to high through the resistance）
When select to NC,that means normally that output line is at low
voltage and when have the coin signal output,then will output the
high level pulse.When select to NO,that means normally that output
line is at high voltage and when have the coin signal output,then
will output the low level pulse.
4、How to connect the coin acceptor ,bill acceptor or coin validator
to PC ( computer act as the master board of vending machine ) ?
For pulse type output of Coin acceptor,if want to connect to the
PC,then would need to use a pulse-RS232 adapter to convert the
pulse signal to RS-232 data.For wafer WF-700 and WF-700B that is
used for this application. and WF-400 is used to covert pulse type
data to USB data
For MDB type coin acceptor,that need to use the MDB-RS232 adapter
board to convert the MDB data to PC. For wafer MDB-RS232 board,that
is for this application.
5、How to select the coin acceptor ?
Coin acceptor include: Single coin coin acceptor, comparable type coin acceptor, multi-coin coin acceptor and coin validator with coin dispensor . Single coin coin acceptor ,normally that is specially designed
to acceptor the specified coin ,so that would has the best
precision and performance. Comparable type coin acceptor,that is
used to accept the coins that is simillar with the coins put aside
the coin acceptor. so that is easy to use and easy to change to
accept different coins or even tokens. For multi-coin coin
acceptor,that can acceptor different coins with one machine,and
output different signal .
6、How to define the precison on prevention the fake coins? If have
the coin acceptor 100%” prevent the fake coins>
Fake coins are always in the market,and that would be important to
select a factory that can improve their quality and continue to
improve their technology to reject the new fake coins.no any coin
acceptor can reject all fake coins ,and some fake coin even the
same as the true coins,so if reject the " fake" coins,that means
that would also reject the similar ture coins.
7、What is the most important points of one coin acceptor ?
Performance to reject the fake coins and stability .
8、Comparable type coin acceptor:
Comparable type coin acceptor,that means there is a comparable
sample coin,that was cliped along the coin acceptor,and use that
parameters of the sample coin to comparable with the coins pass
through the coin acceptor,if that parameters is the similar,then
would accept the coin and output the pulse signal ,and if that is
different,then would reject the coin..
Pull up the coil sensor and put the coin sample inside the coil
sensor ,and then loose the col sensor,then would clip the coins
Note：When you test the coin acceptor, you should make the coins can
pass through the coin acceptor. don't put the coin acceptor on the
table and inset the coins and then wait the pulse single.that is
wrong test method. if the coin stay in the coin acceptor ,that coin
acceptor will not give out the pulse.
11、If Wafer Kiosk control box can work together with any other coin
Normally,that would be better for our customers to select our EU1
or HI-09 coin acceptor, Because our kiosk system already tested
fully with our coin acceptor with all parameters including Pulse
width,working voltage,inhibit voltage level. Of couser if our
customers want to use a better or more economical coin
acceptor,that would be bet
