In a vertical card arrangement for a VME type backplane, the female connectors are on the backplane and the upper connector is called J1, the next lower J2, and so forth. In a vertical card arrangement for a CompactPCI type backplane, the female connectors are on the plug-in cards and the lower connector is called P1, the next higher P2, and so on.


What do P1, P2, and P3 refer to?

 P stands for "plug" and in general (although not always) refers to the male connector. In a vertical card arrangement for a CompactPCI type backplane, the male connectors on the backplane and the lower connector is called P1, the next higher P2, and so on. In a vertical card arrangement for a VME type backplane, the male connectors are on the plug-in cards and the upper connector is called J1, the next lower J2, and so forth.


What is ABG?

 ABG stands for Automatic Bus Grant, which is a 96-pin DIN connector with the additional provision of automatic mechanical busing of VME daisy chain signals through empty card slots. This is provided by mechanical switches internal to the 96-pin DIN connector. This mechanical ABG is not available on the 160-pin (5 row) DIN connector for VME64x; rather, an electrical version, Electronic Bus Grant (EBG) can be used on VME64x backplanes.

What is EBG?

EBG stands for Electronic Bus Grant. EBG is implemented on 160-pin (5 row) DIN VME64x backplanes to provide automatic gating of VME daisy chain signals through empty card slots, provided by logic chips that are part of the backplane assembly.
