Connector Designations

The offi cial PC/104 bus specifi cation identifi es the standard interboard bus connections as paired J1/P1 and J2/P2 on one side and J3/P3 on the other side. However, J1/P1/J2/P2 is physically all one big 4-row connector with J1/J2 bus receptacle sockets (female) on the top side and P1/P2 pins (male) on the bottom. This arrangement provides interboard pass-through connections between PC/104 boards. DATEL refers to this single connector as “J1.”

DATEL’s auxiliary connectors (the IPH and the 5V Auxilliary Power Connector) are internally designated P1 and P2 respectively and this nomenclature may appear on the board silkscreening. This is purely an artifact of automated sequential part numbering in our CAD system and has no relation to the standard PC/104 interboard bus connectors. Don’t get the connectors confused since they are all very different types and locations!
