Chapter 10 - Triad 1/2 System Configuration
Common Control Cards
The common control cards are the plug-in PCB's that are necessary for basic system
operation or require direct interface to the system bus. These cards can only be installed in
the basic cabinet.
Master Processor Board (MPB)
The MPB card controls all system activity. The MPB contains the main microprocessor a 16-bit
(68302), the real time clock, and all support circuitry. The MPB is responsible for all control
functions, execution of all logic operations, and control of system modules. The MPB also
provides software and hardware support to ensure the following:
Watch dog timer and recovery.
State/event software design.
Battery backup of customer database RAM memory.
There is one RS-232 (DB9 connector) input/output port on the MPB. The MPB can support a
total of three RS232 ports. The other serial ports are accessed by installing an optional SIU
module on the MISU board. There is also a provision for an optional 2400 baud modem. There
is a push button reset (halt) switch located on the front of the PCB.
System software is provided in EPROM memory and is installed on the MPB. The MPB can
contain up to 1 MB of EPROM memory storage and up to 512K of RAM. Refer to
“Optional
Units”
for additional information.
