The MVME162LX has two 96-position DIN connectors: P1 and P2.
P1 rows A, B, C, and P2 row B provide the VMEbus interconnection.
P2 rows A and C are not used.
The MVME162LX has a 20-pin connector J2 mounted behind the
front panel. When the MVME162LX board is enclosed in a chassis
and the front panel is not visible, this connector allows the reset,
abort and LED functions to be extended to the control panel of the
system, where they are visible.
The serial ports on the MVME162LX are connected to four 8-pin RJ-
45 female connectors (J17) on the front panel. The two IPs connect
to the MVME162LX by two pairs of 50-pin connectors. Two 50-pin
connectors behind the front panel are for external connections to IP
signals. The memory mezzanine board is plugged into two 100-pin
connectors. The Ethernet LAN connector (J9) is a 15-pin socket
connector mounted on the front panel. The SCSI connector (J23) is a
68-pin socket connector mounted on the front panel.
