  1. The optional I/O cable for the above connector consists of twisted pair wires--pairs of #1 and #35, #2 and #36, #34 and #68.
  2. If no Protective Stop input signals are needed, short-circuit by terminal connection with jumpers between #4 and #38 and between terminals #5 and #39.
  3. For Compatible Mode/Standard Mode/All User I/O mode,
    terminals #11 to #18 are user input, termilals #46 to #53 are user output.

The reserved pins and output pins should be prevented from direct contact with other pins or conductive part. Direct contact could result in a controller failure or damage.
