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 …

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.

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.

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.

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.

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.

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 ...

Sep 19, 1999 · 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.

Mar 1, 1998 · 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 …

The MVME172P2 allows VME embedded controller users to achieve the price-performance value of RISC architectures while maintaining MC68000 object code compatibility.
