What if my keyboard connector does not fit into the keyboard port
on the VXIpc 800?
You can plug keyboards that have a 6-pin Mini DIN PS/2 type
connector directly into the VXIpc 800. You can use the keyboard
adapter cable that is included with every VXIpc 800 kit to adapt the
larger AT keyboard connector to the 6-pin Mini DIN connector.
How do I connect an external speaker to get audio capability?
A twisted-pair cable connects the front panel audio connector to the
VXIpc 800 Series motherboard. Connect the external speaker to this
front-panel connector. The center pin of the connector provides the
audio signal. The shield of the connector is GROUND.
How do I add RAM to the VXIpc 800? What is the maximum
amount of RAM that I can have on the VXIpc 800?
For information about adding RAM to the VXIpc 800, refer to
Appendix A, Specifications.
Which interrupt levels are free to be used by ISA bus boards?
Which area of upper memory (adapter space) is free for use by ISA
bus boards or expanded memory manager software programs?
See Appendix B, VXIpc 800 Series System Resources, for information
on the available port I/O register space, upper memory area, interrupts,
and DMA channels.
How do I install the VXIpc 800 in a slot other than Slot 0?
The VXIpc 800 automatically detects whether it is in Slot 0 of a VXIbus
mainframe. You do not need to change jumper settings to install the
VXIpc 800 in a slot other than Slot 0 unless you have defeated the first
slot detector (FSD) circuitry by changing the appropriate jumper setting
on the VXIpc 800.
Refer to either Chapter 3, VXIpc 800 Series Configuration and
Installation, for information on enabling and defeating the FSD
circuitry.
