System Considerations

Other MPUs on the VMEbus can interrupt, disable, communicate with,
and determine the operational status of the processor(s). One register of
the GCSR (global control/status register) set includes four bits that
function as location monitors to allow one MVME1603/1604 processor to
broadcast a signal to any other MVME1603/1604 processors. All eight
registers are accessible from any local processor as well as from the
VMEbus.
The MVME1600-001 and MVME1600-011 base boards draw +5Vdc,
+12Vdc, and –12Vdc power from the VMEbus backplane through
connectors P1 and P2. The 3.3Vdc power (used by the ISA Super I/O
device on the base board, and by the PM603 or PM604 processor/memory
mezzanine) is derived on-board from the +5Vdc.
MVME1600-001 Base Board
The MVME1600-001 base board fur12Vdc, –12Vdc, and +5Vdc
power to the MVME760 transition module through polyswitches
(resettable fuses) F4, F2, and F3. The MVME760 uses these voltage
sources to power the serial port drivers and any LAN transceivers
connected to the transition module. The
FUS
LED (DS5) on the
MVME1600-001 front panel illuminates when all three voltages are
available.
The fused +5Vdc power is also supplied to the base board’s keyboard and
mouse connectors and to the 14-pin combined LED-mezzanine/remote-
reset connector, J1.
In addition, the MVME1600-001 base board pr5Vdc to the SCSI
bus
TERMPWR
signal through fuse F1, located near the front panel SCSI
connector. The
FUS
LED (DS5) on the front panel monitors the SCSI bus
TERMPWR
signal along with the other operating voltages; when the
MVME1600-001 is connected to an SCSI bus, either directly or via the
MVME760 module, SCSI terminator power helps illuminate the
FUS
LED.
