C1.2 ITM-RIO Rear-Panels (4HP or 8HP)
As with front-panel I/O, the physical interfaces from the ITM-RIO-D-x rear I/O module are brought
out to a face plate (rear panel). Figure C1.2 illustrates the three standard formats available (at time
of press.)

The rear I/O options described here do not detract from the latest PICMG 2.0 R3.0 specification.
The VGA option in table C1.10 can be from either the chipset or the AGP piggyback option. Using
the chipset graphics for both front and rear I/O simultaneously is not advisable as the loading may
be too great. If both front and rear I/O VGA are required then the twin-engined, Radeon-based
AGP piggyback graphic option should be used.
The single channel Fast Ethernet option in table C1.10 is either ETH1 or ETH 2 on the front-panel
depending on the computer platform. If the rear I/O option is used then the front-panel connec-
tion must not be used. Doing so will disrupt the communication leading to spurious results.
If the mouse, keyboard and COM ports are used in rear I/O applications then they should not be
used from the front-panel. Communicating from both mouse and keyboard sources is physically
possible but is not recommended!
