2.11 Further Options
2.11.1 Power Supply Connections Reversed (Option /A)
The polarity of the power supply inputs are reversed with this option, i.e. pin 1 of
the EMP connector is UB (instead of GND) and pin 2 is GND (instead of UB). As
there is no output channel being used for the reject signal, 7 output channels are
now available. This version is especially designed for gaming machines on the
Spanish market.
2.11.2 Large Coin Funnel (Option /F)
An alternative funnel can be supplied if a bigger insertion is required. Dimensions
are shown in the drawings below.
3 Serial Interface
The EMP 800 v5 serial interface communicates over one of three different
protocols with the vending machine. The first serial protocol is the SCI (serial
communication interface), in which the coin selector sends out a 5-byte data frame
to the machine controller after each event. The other serial protocol is the multi
drop bus protocol, which also serves as the programming interface. The third serial
protocol is cctalk, which has its own connector.
All three interfaces operate at 9600-baud rate.
3.1 Interface Connector
An AMP (Quick 828548-5) single in line 5-pin connector is used as serial connector
for the SCI and multi drop bus protocol.
PIN No. Description
1 GND (ground)
2 UB (positive power supply, 8 to 18 volts DC)
3 CLK (clock)
4 TDO (transmit data out)
5 RDI (receive data in)
