Using the PC/104 -Plus expansion bus
PC/104-Plus modules can be used with the ISIS to add extra functionality to the system.
This interface supports 5V and 3.3V signalling, 33MHz 32-bit PCI bus peripherals that
conform to the PC/104-Plus specification.
To use a PC/104-Plus peripheral module with the ISIS, plug it into J3. Before powering up
the system, please consult the user manual supplied with your peripheral module to
ensure correct signalling voltage. To select the correct signalling on the ISIS, use jumper
JP1 to set the correct VIO voltage (see page
48 for details).
The ISIS supplies only the selected VIO voltage to the PC/104-Plus stack, as defined by
the
PC/104-Plus Specification Version 2.0 . +5V is also supplied to the stack directly from
the input power connector J9.
+12V and -12V are only available if you connect the +12V and -12V pins on the power
connector J9 to a supply, otherwise they must be supplied directly to the PC/104-Plus
stack. If you r3.3V, it must be supplied directly to the PC/104-Plus stack.
For more information, see PC/104-Plus bus interface , page 21 , or for connector pin
details see page 36 .
