13.2 Functional Description

The Main Board has four serial channels - 0, 1, 2 and 3. Channel 0 has a non-isolated
interface to a FIP display (stepper only) and an RS232 interface. This channel is
reserved for communications with a Touchscreen interface or a Serial Keno Panel
interface. Channels 1, 2 and 3 are fully isolated and can be configured using the
Communications Configuration Board.
On Board 410165, COM 0 is reserved for RS-232 communications with a
touchscreen. COM 1, COM 2, and COM 3 are fully isolated and are configurable via
the Communications Configuration Board (CCB). The CCB is supplied from the
main board with isolated +12V at 100 mA for the communications channels and 5 V
DC (VCC) (converted from the 24 V DC supply by the I/O Driver Board) to power
the logic.

The CCB plugs into the Main Board via a standard 72-pin SIMM socket and converts
the opto-coupled UART serial and I/O signals into the desired signal levels. There
are several different CCBs used to configure the communications channels for
different signals to suit different markets. The table below shows the CCB part
numbers and the associated configuration.
