PC/104 BUS
NOTES
:
1. Rows C and D are not required on 8-bit modules.
2. B10 and C19 are key locations. WinSystems uses key pins as connections to GND.
3. Signal timing and function are as specified in ISA specification.
4. Signal source/sink current differ from ISA values.
# = Active Low Signal
The PC/104 bus is electrically equivalent to the 16-bit ISA bus. Standard PC/104 I/O cards can be populated on
EPX-C380’s connectors, located at
J12
and
J15
. The interface does not support hot swap capability. The PC/104 bus
connector pin definitions are provided below for reference. Refer to the
PC/104 Bus Specificatio
n
for specific signal
and mechanical specifications.
