10. Connect the appropriate cable(s) to the panel connectors for the serial
and parallel ports, SCSI port, and LAN Ethernet port.
Note
Some cables are not provided with the MVME712 series
module; they must be made or purchased by the user.
(Motorola recommends shielded cable for all peripheral
connections to minimize radiation.)
11. Connect the peripheral(s) to the cable(s).
12. Install any other required VMEmodules in the system.
13. Replace the chassis cover.
14. Connect the power cable to the AC power source and turn the
equipment power ON.
System Considerations
The MVME167P draws power from VMEbus backplane connectors P1
and P2. P2 is also used for the upper 16 bits of data in 32-bit transfers, and
for the upper 8 address lines in extended addressing mode. The
MVME167P may not operate properly without its main board connected
to VMEbus backplane connectors P1 and P2.
Whether the MVME167P operates as a VMEbus master or VMEbus slave,
it is configured for 32 bits of address and 32 bits of data (A32/D32).
However, it handles A16 or A24 devices in the address ranges indicated in
the VMEchip2 chapter of the Programmer’s Reference Guide. D8 and/or
D16 devices in the system must be handled by the MC68040 software. For
specifics, refer to the memory maps in the Programmer’s Reference Guide.
The MVME167P contains shared onboard DRAM whose base address is
software-selectable. Both the onboard processor and offboard VMEbus
devices see this local DRAM at base physical address $0000 0000, as
programmed by the MVME167Bug firmware. This may be changed via
software to any other base address. Refer to the MVME1X7P Single Board
Computers Programmer’s Reference Guide for more information.
If the MVME167P tries to access offboard resources in a nonexistent
location and is not system controller, and if the system does not have a
