other coins. With selective cloning all coin channels with activated coin boxes will
be cloned.
The actual cloning process takes about 15 seconds after the OK button has been
pressed.
2.3 Coin Selector Output Signals
There are 6 open collector parallel outputs (current sink) on the EMP 800 v5 10-pin
connector. They can be freely assigned in any combination to the 16 master
channels. This means that (depending on the model) one coin channel can show
up on multiple output lines or that one output line can be activated by multiple
channels. The 16 slave channels always have the same output combination as the
associated master channel.
In addition the number of output impulses for every coin can be programmed (multi
pulse operation).
The coin selector signals an active LOW pulse after accepting a programmed coin
or token to a particular output line or to a combination of output lines. Pulse width
(in case of multi pulse operation also pulse pauses) can be programmed between
1ms and 65 ms.
For some applications it is necessary to invert the output signals, i.e. switching
from LOW to HIGH instead of from HIGH to LOW. This can easily be programmed
using wheasy 3.
This multiple configuration possibilities guaranties highest flexibility of the
selectors. The wheasy 3 manual details the assignment of output lines to specific
coin channels, as well as the pulse width assignment.
2.3.1 EMP 8x0.00 v5 Interface
Only one output line per channel is assigned on the EMP 8x0.00 v5.
Correspondingly, only 6 different coin type signals can be identified with this
version. If more than 6 coin values are required the multi pulse operation can be
used. For example 2 pulses can be generated for 20 Cent on 10 Cent output line.
2.3.2 EMP 8x0.04 v5 Interface
Multiple output lines can be assigned with the EMP 8x0.04 v5 version and each
coin channel can have a binary coded output. Multi pulse can also be generated
with binary coded output signals.
! The coin selector will not give any output pulse if a coin channel is
assigned the value of 0. The coin, will however, be accepted.
2.3.3 EMP 8x0.13 v5 Interface
The EMP 8x0.13 v5 supports the serial multi drop bus protocol (mdb) and the
cctalk protocol. Chapter 3 has more information about this interface.
2.3.4 Preceding coin output signal (Option /S)
The selector can be programmed at the factory to give an assigned preceding coin
output signal. This output pulse is given as soon as the coin has been identified.
