6. On the chassis backplane, remove the
(IACK) and
BUS GRANT
slot occupied by the controller.
7. Connect the appropriate cable(s) to the controller's panel
connectors for the EIA-232-D serial ports, SCSI port, and LAN
Ethernet port.
– Note that some cables are not provided with the MVME162LX
module and must be made or purchased by the user (Motorola
recommends shielded cable for all peripheral connections to
minimize radiation).
8. Connect the peripheral(s) to the cable(s).
9. Install any other required VMEmodules in the system.
10. Replace the chassis cover.
11. Connect the power cable to the AC power source and turn the
equipment power ON.
The MVME162LX Embedded Controller draws power from both the P1 and
the P2 connectors on the VMEbus backplane. 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 controller may not operate properly without
its main board connected to VMEbus backplane connectors P1 & P2.
Whether the controller operates as a VMEbus master or as a 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
Chapter 3. D8 and/or D16 devices in the system must be handled by the
MC68040/ MC68LC040 software. Refer to the memory maps in the
MVME162LX Embedded Controller Programmer's Reference Guide.
The controller 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 $00000000, as
programmed by the MVME162Bug firmware. This may be changed via
software to any other base address. Refer to the MVME162LX Embedded
Controller Programmer's Reference Guide for additional information.
