10.4 Address Selection
The default ccTalk bus address for a ‘Payout’ device is 3. This is the address of the Serial
Compact Hopper if no connections are made to the address select pins (pins 1 to 3) on the
connector.
For applications requiring more than one hopper on the serial bus, one or more of the
address select lines may be connected to +Vs. A total of 8 unique bus address may be
generated in this way, in the range 3 to 10 inclusive.

A number of mating connectors on a multi-drop bus cable may each be wired uniquely to
allow operation of multiple hoppers. Since address selection is done externally, any Serial
Compact Hopper may be plugged into any position on the bus and the host machine will
know which one is paying out a particular coin.
Address determination from the connector is only done at power-up or reset. Changing the
address select lines afterwards has no effect.
Note : Addresses may be changed in software to values other than those in the above
table. Refer to the ‘Address change’ and ‘Address random’ serial commands. These
values are lost at power-down or reset.
