Serial Channels; Communication Configuration Board - Aristocrat USA MAV500/MKVI Service Manual

Main Board
SPI Channels Functional Description
The board has seven SPI channels selected via three bits in an output register.
Channel 0 is defined as the reset or null state. Data written to channel 0 will be read
back in its bitwise inverted state as a diagnostic test.
The seven channels are allocated as follows:
Channel 1
Channel 2
Channel 3
Channel 4
Channel 5
Channel 6
Channel 7

Serial Channels

The board has four serial channels, referred to as channels 0,1, 2, and 3, any of which
may be used to communicate with peripheral equipment and external network
interfaces. The serial channels are implemented via two PC compatible DUART's.
The serial debug channel is implemented on the SH-4.
Channel 0 has a non-isolated interface to a Fluorescent Interface Panel (FIP) and an
RS232 interface. Channels 2 and 3 are fully isolated and are configurable via the
Communications Configuration Board (CCB). Channel 1 is not isolated.
Channel 1 is allocated to the Bank Note Acceptor and is implemented on the Main
Board (applies to Bank Note Acceptor V2.2).
The serial ports are implemented using an industry standard 16C554 UART. Each of
the three generic serial channels (channels 1 to 3) has 1-receive-data, 1-transmit-data,
3 input and 3 output handshake lines.
The maximum baud rate supported is 9600 baud, except on channel 2 which uses fast
optocouplers.

Communication Configuration Board

Serial channels 2 and 3 are configured through the Communications Configuration
Board (CCB) which is plugged into the 72-pin SIMM socket on the Main Board. The
CCB converts the opto-coupled UART I/O to any of the following signal levels:
RS232
•
Current loop (Open collector)
•
Bank Note Acceptor interface
•
Serial printer
•
TTL compatible level
•
Other
•
Refer to the chapter Communications Configuration Board (CCB) for additional
information.
