Product Overview

Inova’s CPUs have been prepared for rear I/O operation. Currently RIO-D is supported with VGA,
single-channel Fast Ethernet, second EIDE channel, USB 1.1, mouse, keyboard, reset and loud-
speaker (beeper) and a software selectable choice between LPT1, COM1& COM2 or floppy drive.
Other rear I/O options may also be available (including customer specific) but are not referred to
in this user’s handbook. For OEM quantities and compatibility with existing 2.11 backplanes etc.
RIO-C1 could be considered - this is identical to rear I/o (D) except that the VGA, COM and PS-2
mouse options are not available. In order to take full advantage of the rear I/O features, the
CompactPCI backplane needs to support them. Inova provides two standard versions; the first has
the rear rP2 connector on the Master CPU slot only while the other has all slots fitted with rP2
connectors.
Be aware that boards using the PXI bus will experience signal conflict if used with any (includes
non Inova boards) CPU offering rear I/O - Therefore, in such cases always select a CPU board
configuration without rear I/O. Also, for compatibility with older backplane revisions (2.11), rear
I/O (C) should be selected if indeed rear I/O is required. CPUs configured with rear I/O (D) will not
work!
