XVME 400/401/490/491 Manual
October, 1989
All XVME-401 signal names are in the form "XXNZ", where "N" is
the channel number, "Z" is A or B based on the polarity of the
differential signal (as defined by RS-485),
the signal. Also see Section 2.4.4.
All JKl and JK2 pin numbers not referenced are not connected.
2.5.2 Pl and P2 Connectors
The Pl and P2 connectors are the same physical type and have the same number of pins.
Both are 96-pin connectors consisting of three rows of 32 pins each. Like Pl, P2 is
mounted at the rear edge of the module. The pins for Pl contain the standard address,
data, and control signals necessary for the operation of VMEbus-defined
(The signal definitions and pin-outs for connector Pl are found in Appendix A of this
manual.) The PI connector is designed to mechanically interface with a VMEbus defined
P 1 backplane.
The P2 connector (XVME-490/491 only) is a standard VMEbus P2 backplane connector.
It is designed to interface with a VMEbus defined P2 backplane.
2.5.2.1 P2 Connector Pinouts on the XVME-490 (RS-232C)
Table 2-10 shows the XVME-490 pinouts for connector P2. These signals meet the RS-232C
and VMEbus specifications.
