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 JKl 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):
