General Description
The MVME162 is a double-high VMEmodule equipped with an MC68LC040
or optional MC68040 microprocessor. (The MC68040 microprocessor has a
floating-point coprocessor; the MC68LC040 does not.)
The MVME162 has 1MB, 4MB, or 8MB of parity-protected DRAM; 512KB
SRAM (with battery backup); a TOD clock (with battery backup); an optional
LAN Ethernet transceiver interface with DMA, two serial ports (EIA-232-D
and EIA-232-D/EIA-530); six tick timers with watchdog timer(s); optional
SCSI bus interface with DMA; VMEbus interface (local bus to
VMEbus/VMEbus to local bus, with A16/A24/A32, D8/D16/D32 bus widths
and a VMEbus system controller).
Input/Output
Input/Output (I/O) signals are routed through 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 (MVME712-12,
MVME712-13, MVME712A, MVME712AM, or MVME712M). The transition
module routes the signals to the appropriate configuration headers and
industry-standard connectors. Refer to the MVME712-12, MVME712-13,
MVME712A, MVME712AM, and MVME712B Transition Modules and LCP2
Adapter Board User’s Manual or the MVME712M Transition Module and P2
Adapter Board User’s Manual for more information.
N
otes
When used with the MVME162, only serial ports 2 and 4 on
the MVME712 are available for use. Serial ports 1 and 3 and
the printer port are not connected to any MVME162 circuits
and should not be used.
An I/O device may be connected to serial port 1 (or 2) on the
MVME162 or to serial port 2 (or 4) on the MVME712, but not
both. (That is, if an I/O device is connected to MVME162
port 1, no other I/O device should be connected to
MVME712 port 2; they are functionally the same port.)
