Introduction
This user's manual provides general information, preparation for use and
installation instructions, operating instructions, and a functional description
for the MVME197DP and MVME197SP versions of the MVME197 series of
single board computers, hereafter referred to as the MVME197, unless
separately specified.
General Description
The MVME197 module is a double-high VMEmodule based on the MC88110
RISC (Reduced Instruction Set Computing) microprocessor.
The MVME197DP/SP module series have 128/256MB of onboard DRAM with
programmable ECC (Error Checking and Correction), 256KB of external cache
memory for each MC88110/MC88410 microprocessor/cache controller
combination (note that the MVME197SP module series have only one
MC88110/ MC88410 device combination), 4MB of flash memory, 8KB of static
RAM (with battery backup), a time of day clock (with battery backup), an
Ethernet transceiver interface, four serial ports with EIA-232-D interface, six
tick timers, a watchdog timer, 256KB of BOOT ROM, a SCSI bus interface with
DMA (Direct Memory Access), a Centronics printer port, an
A16/A24/A32/D8/ D16/D32 VMEbus master/slave interface, and a
VMEbus system controller.
Input/Output (I/O) signals are routed through the MVME197's backplane
connector P2. A P2 Adapter Board or LCP2 Adapter board routes the signals
and grounds from connector P2 to an MVME712 series transition module. The
MVME197 supports the MVME712M, MVME712A, MVME712AM, and
MVME712B transition boards (referred to here as the MVME712X, unless
separately specified). The MVME197 also supports the MVME712-12 and
MVME712-13 (referred to as the MVME712-XX, unless separately specified).
These transition boards provide configuration headers, serial port drivers, and
industry standard connectors for the I/O devices.
The MVME197 modules utilize eight ASIC devices (Application-Specific
Integrated Circuits) described in the following order: BusSwitch, DCAM,
ECDM, PCC2, and VME2.
