Vector offers wide range of VME backplanes from 3 to 21 slots wide in J1 and J2 are 3U backplanes. All VME backplane boards are constructed from FR4 epoxy glass material and are assembled and tested. Press fit connectors are used throughout on all sizes.
Vector J1 VME backplanes handle high signal densities and circuit speeds with integrity and reliability. Six layer construction and controlled impedence design effectively reduce crosstalk and ringing on bus lines. Massive copper clad power and ground planes on opposite board sides; patented shielding technique effectively surrounds each signal trace with a closed conductive loop for blocking both capacitive and inductive coupling.

Daisy Chain Jumpers for J1 backplane
The interrupt acknowledge and bus grant daisy chain signals must be jumpered on this backplane when a slot is not occupied, and if there are boards further down (towards RIGHT) the backplane. Jumper connection locations are identified at each connector on the rear of the backplane, Jumper connections may be made by wire-wrapping or by using 0.100” X 0.100” push-on jumpers or shunt, made for 0.025” square wire-wrap posts.
Terminator Boards for VME backplane
A pair of Terminator boards are included with each J1 and J2 VME backplane and are also available separately. There are two versions : Perpendicular (standard) and parallel. The latter offers a lower profile (Normal profile : 1.0", parallel : 0.5") than the perpendicular, if this is needed.
