In order to allow both bus widths, VME uses two different Eurocard connectors, P1 and P2. P1 contains three rows of 32 pins each, implementing the first 24 address bits, 16 data bits and all of the control signals. P2 contains one more row, which includes the …

In 6U and 9U systems there can be transition modules installed on the rear side of the backplane. Transition modules do not connect to VMEbus but just to the VMEbus module on the opposite side of the backplane via the user defined pins of the J0, J2 and J3 connectors.

Aug 11, 1999 · Voltage pre-charge [VPC] pins forma a 'make first / break last' contact. They are intended to be used as pre-charge power sources for live insertion logic. These pins were added to the 160 pin P1/J1 and P2/J2 connectors in the VME64x specification. The VPC pins are connected to the +5 VDC power supply on VME64x backplanes.

Apr 26, 2024 · VPX总线是VITA(VME International Trade Association, VME国际贸易协会)组织于2007年在其VME总线基础上提出的 新一代高速串行总线标准 。VPX总线的基本规范、机械结构和总线信号等具体内容均在ANSI/VITA46系列技术规范中定义。

The P1 & P2 connectors include four (4) first-make / last-break (fmlb) contact positions for hot- swap boards, and are used to pre-charge bus interface circuitry. These connectors are available from Harting and AMP Inc.

Mar 1, 1998 · These pins were added to the 160 pin P1/J1 and P2/J2 connectors in the VME64x specification. The VPC pins are connected to the +5 VDC power supply on VME64x backplanes. These pins may also be used as additional +5 VDC power pins in …

Jun 6, 2022 · In order to allow both widths of buses to be used, VME uses two different Eurocard connectors, the P1 and P2. P1 contains three rows of 32 pins each, implementing the first 24-bits of the address and 16-bits of the data buses, along with all of the control signals. The P2 contains one more row, which includes the remaining 8 address and 16 data ...
