October, 1989
JKl AND JK2 CONNECTORS
The XVME-400 and XVME-401 have JKl and JK2 connectors, which are
50-pin
connectors consisting of three rows of 32 pins each. Table A-5 identifies the RS-232C
signals carried by the JKl and JK2 connectors on the XVME-400. Table A-6 shows
the
RS-485/422A signals carried by the JKl and JK2 connectors on the XVME-401.

NOTE
All XVME-400 signal names are in the form XXXN where “N” is the
serial channel number and “XXX” is the name of the signal.
All JKl and JK2 pin numbers not referenced are not connected.
The pinouts of JKI and JK2 allow a 50-conductor flat cable to be connected, split into
two 25-conductor sections, and have 25-pin D-type connectors installed on the two 25-
conductor sections. The position of the signals relevant to the 25-pin D-type connectors
will be in accordance with the RS-232C definition (no line Transitions are required):
TXD Pin 2 DCD Pin 8
RXD Pin 3 RXC Pin 17
