Century Series Options
Asymtek offers a wide range of special options for fine-tuning your dispensing applications.
This section introduces the options currently available for Century Series systems. For
optional accessories available for this and other Asymtek platforms, see the sections on
cross-platform options (9-15).
Expanded Opto-I/O
The Expanded Opto-I/O option for your Century Series system provides access to 24 I/Os.
Century Series systems use 8-bit I/Os for normal operation of all system components.
Expanded Opto-I/O lets you add accessories such as external devices or sensors.
Connectors for Expanded I/O ports A, B and C are located on the I/O Board, which is under
the top cover of the dispenser at the corner of the Electronics Pan nearest the Light Beacon.
Cables from the three 26-pin female D-Sub connectors can be routed over the I/O Board to
exit through a slot at the middle rear of the machine, shown in Figure 16-1. The same three
connectors can be reached from underneath the I/O Board by removing the two side panels.
