The individual fields are defined as follows:
•
S.Value (Calculated Coin value)
A calculated coin value is the value transferred to the coin selector. The
calculated coin value represents the inventory value.
•
Value (Actual coin value)
This “value” is not stored in the coin selector. In certain situations it may
be necessary to give a coin an S.value other than its face value. For
example, a rebate value may be assigned to a particularly valuable coin.
In this case, the “value” is displayed for clarity when working with
w
heasy
2.
•
Curr. (Currency)
The currency description is not stored in the coin selector. However, it is
still important to have this description when working with
w
heasy 2
because a coin selector may be programmed to accept multiple
currencies.
•
Rem. (Remark)
The remarks are not stored in the coin selector. They serve to provide a
better overview when working with
w
heasy 2. Supplementary information
such as “broad” or “narrow”, “old” or “new”, or “before 74” or “64-76” etc.
may be entered here.
•
TM (Teach mode)
This choice enables the coin selector mounted DIP switch teach mode
function for a channel. This mode is activated when the appropriate box
shows a “
√√
“.
From the series v4 onwards a star (*) may be shown to the left of the “TM”
checkbox. The star indicates that this master channel also has a slave channel
associated with it (See section 2.6).
There are some special fields at the bottom of the window, below the heading of
“Scaling.” These adjustable parameters have the following meaning:
•
Scaling Factor
This value is used in vending machines that communicate with the coin
selector over the serial MdB protocol. The vending machine may read
these values during a status request. This is not significant for the EMP
500 v4.
•
Decimals
A decimal point location is likewise transferred to the vending machine
during a status request as part of the MDB protocol. This value tells the
vending machine how many digits to use after the decimal point as part of
the coin value. This is not significant for the EMP 500 v4.
•
Set Value
A set value represents one impulse when inventory pulses are generated.
For those coin selectors that calculate prices and the price is set up via the
binary price switches, the set value is also used as the multiplication
factor.
•
Test button
This button is used to let
w
heasy 2 test whether it is possible to create 8
bit coin values for the MdB status request with the given scaling factor and
decimal location. This is not significant for the EMP 500 v4.
