GE DS200VPBLG1A VME Backplane Board

GE DS200VPBLG1A VME Backplane Board

Functional Description

The DS200VPBLG1A VME Backplane Board (VPBL) is the VME backplane for the J2 and J3 sections of the

equipment's card cage.

Section J2

Section J2 supports a number of boards:

· Digital Signal Processor Control Board (DS200DSPC) with daughterboards in slot J1.

· I/O extender with daughterboards in slot J3, to the right of the DSPC.

· Up to three Gate Distribution and Status Boards (DS200 FCGD) in slots J5, J7, and J9.

· One exciter board in slot J11.

· Two spare slots, J12 and J13.

All slots, except Slot 1, have the slot identifictation number (ID) permanently hardwired at the P2 connector.

Only control signals on the digital bus, such as the 16 MHz clock signal, terminate at the end of slots. The

pins in the B row of the J2 connectors are only connected to the P5 and DCOM pins.

Section J3

The J3 area is used for external connections that are not on board fronts because of space or other

restrictions. These include connections to the current transformers (CT) and their associated burden resisters,

and Voltage Scaling Feedback Board (DS200 NATO) connections for the FCGD.

The J3 area also establishes the power connections to the backplane. Stab connectors are available in the J3

area for establishing various grounding schemes.
