All boards are available with 512KB of SRAM (with battery backup);
time-of-day clock (with battery backup); an optional Ethernet transceiver
interface; two serial ports with EIA-232-D or EIA-530 or EIA-485/-422
interface; six tick timers with watchdog timer(s); an EPROM socket; 2MB
Flash memory (one Flash device); four IndustryPack (IP) interfaces with
DMA; optional SCSI bus interface with DMA; and a VMEbus interface
(local bus to VMEbus/VMEbus to local bus, with A16/A24/A32,
D8/D16/D32 bus widths and a VMEbus system controller).
I/O Implementation
Input/Output (I/O) signals on the MVME172P4 are routed to the VMEbus
P2 connector. The main board is connected through a P2 adapter board and
cables to the transition boards. The MVME172P4 supports the
MVME712M and MVME712B series of transition boards (referred to in
this manual as MVME712x, unless separately specified).
The MVME712x transition boards provide configuration headers, serial
port drivers, and industry-standard connectors for various I/O devices.
Although the MVME712x series transition boards were originally
designed to support MVME167 boards, they lend themselves readily to the
MVME172P4 application as long as you keep a few special considerations
in mind (refer to the section on the Serial Communications Interface, later
in this chapter, for details).
The I/O connection for the serial ports on the MVME172P4 is also
implemented with two DB25 connectors on the front panel. In addition, the
panel has cutouts for routing of flat cables to the optional IndustryPack
modules.
