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 …

1999年8月11日 · 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.

P1/J1 and P2/J2 Connectors The VME64x specification describes three connectors for VMEbus modules. These are called the P0/J0, P1/J1 and P2/J2. The 'P' and 'J' nomenclature refers to the PLUG (male) and JACK (female) connectors, which reside on the bus module (daughtercard) and backpanel respectively.

The measuring board can be fully programmed by interface bus (VME or ISA) or P2 interface. Lower integration. Cost standard hardware interface, supporting up to 7.7 MHz P2 data rate, suitable for up to 16 axes. Easy to expand and accommodate more axes at the same rate.

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. Asynchronous with 4 edge handshaking. VMEbus is big endian.

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.

1999年9月19日 · The P2 64 User Defined I/O lines have provided VMEbus with the flexibility to meet a wide variety of application needs. They can be used for special signals, board input/output, or secondary bus implementation. When setting up a VMEbus system, the system developer needs to map out P2 use to make sure that application requirements are met.

1998年3月1日 · VME64 P2 Connector - 160 pin DIN (41612, Type C Expanded) 5 rows x 32 pins [Pitch 2.54mm (.100")] @ ANSI/VITA 1-1994. VMEbus is a computer architecture. The term ‘VME’ stands for VERSAmodule Eurocard and was first coined …

2016年6月17日 · 本申请涉及VME P2五排接口适配器组件、系统及方法。 具体地，Versa Module Europa (VME)适配器组件 (100)被配置成可操作地将子系统联接至五排VME64x底架。 所述VME适配器组件 (100)包括：适配器电路板 (102)，该适配器电路板 (102)具有靠近底架配合边缘 (104)的配合接触区 (140)，和被配置成联接至所述子系统的、靠近系统连接边缘 (106)的至少一个区域。 配合插头外壳 (126)联接至所述配合接触区 (140)，并且可以包括底架接口插入部 (130)，该底架 …

This document describes the pin assignments and signal descriptions for the VMEbus connectors. It provides the pin layout for the P1/J1, P2/J2, and P0/J0 connectors, identifying the signals assigned to each pin, such as address lines, data lines, control signals, and power pins.
