In certain circumstances, the general blocking signal can also be used to block
individual coins (chapter 2.3.4 preceding coin output signal – Option /S).
2.4.2 Individual Coin Blocking via DIP switches
The coin selector has 16 DIP switches for individual coin blocking. Blocking is not
active, that is, the coin will be accepted when the switch is in the “OFF” position. A
coin will be rejected when the switch is “ON”.
The 16 switches can be freely assigned to the 32 coin channels. Each coin
channel can be associated with two switches. This configuration makes it possible
to block individual coins or, if multiple currencies are programmed, it is possible to
block a whole currency with one switch. For example 12 individual coins can be
assigned to the first 12 switches. Then switch 13 to 16 can be used to block whole
currencies. This optimal use of the switches allows the easy selection of one
currency or even multiple currencies at the same time.
The following figure illustrates the assignment of blocking switches and also the
numeric identity of each switch.
The lower switch position is the “Off“
position. The upper switch position
denotes “ON”. In this example all coins
assigned to switch 7, 8 and 15 are
blocked.
Figure 9 Blocking assignment.
The programming of the blocking switches is done with wheasy 3 and is explained
in the wheasy 3 technical manual.
2.4.3 Individual Coin Blocking via the Parallel Output Lines (/O Option)
The /O option makes it possible to block up to 6 coins or coin groups through the 6
parallel (open collector) output lines. This blocking is accomplished when the
machine controller pulls the associated output line LOW.
Note that this blocking option has the same effect as the blocking switches 9
through 14 to the micro processor.
! This option must be specified at the time that the coin selector is
ordered. The coin selector cannot be retrofitted with this option.
2.5 Coin Values
Each coin programmed into the coin selector is also given a coin value. This value
may be used for the inventory impulses and it is also used as part of the MDB
status request. Most importantly programming the coin values display a check on
what is already programmed in coin selector including channel assignments.
16 different coin values can be programmed into the master channels. The slave
channels always have the same coin value as the master channel.
The “Coin Values“ selection is available under the “Edit“ pull down menu. This
window can be used to set and edit the coin values for each channel. Please note
that only part of the information in this window is transferred to the coin selector.
The rest is just stored as part of the data on the PC and is used to better describe
and understand each channel while working with wheasy 3.
