Connector pinout: Compact PCI PCI=Peripheral Component Interconnect. CompactPCI is a version of PCI adapted for industrial and/or embedded applications. Since CompactPCI is based on PCI you should first refer to the PCI standard. This only explains the extensions CompactPCI specifies. pin name direction description color Z1 GND Ground Z2 GND Ground Z3 GND Ground Z4 GND Ground Z5 GND Ground Z6 GND Ground Z7 GND Ground Z8 GND Ground Z9 GND Ground Z10 GND Ground Z11 GND Ground Z12 KEY Keyed (no pin) Z13 KEY Keyed (no pin) Z14 KEY Keyed (no pin) Z15 GND Ground Z16 GND Ground Z17 GND Ground Z18 GND Ground Z19 GND Ground Z20 GND Ground Z21 GND Ground Z22 GND Ground Z23 GND Ground Z24 GND Ground Z25 GND Ground Z26 GND Ground Z27 GND Ground Z28 GND Ground Z29 GND Ground Z30 GND Ground Z31 GND Ground Z32 GND Ground Z33 GND Ground Z34 GND Ground Z35 GND Ground Z36 GND Ground Z37 GND Ground Z38 GND Ground Z39 GND Ground Z40 GND Ground Z41 GND Ground Z42 GND Ground Z43 GND Ground Z44 GND Ground Z45 GND Ground Z46 GND Ground Z47 GND Ground A1 5V +5 VDC A2 TCK Test Clock A3 INTA# Interrupt A A4 BRSV Bused Reserved (don't use) A5 BRSV Bused Reserved (don't use) A6 REQ# Request PCI transfer A7 AD(30) Address/Data 30 A8 AD(26) Address/Data 26 A9 C/BE(3)# Command: Byte Enable A10 AD(21) Address/Data 21 A11 AD(18) Address/Data 18 A12 KEY Keyed (no pin) A13 KEY Keyed (no pin) A14 KEY Keyed (no pin) A15 3.3V +3.3 VDC A16 DEVSEL# Device Select A17 3.3V +3.3 VDC A18 SERR# System Error A19 3.3V +3.3 VDC A20 AD(12) Address/Data 12 A21 3.3V +3.3 VDC A22 AD(7) Address/Data 7) A23 3.3V +3.3 VDC A24 AD(1) Address/Data 1) A25 5V +5 VDC A26 CLK1 Clock ??
