DC supply cables
Two DC supply cables are packed with each AT-RPS 740. If making your own
cable, use a cable that conforms to UL2464, and has at least twenty-three
24AWG cores. The cables will need a DB25 male connector on both ends and
should be wired in a straight-through configuration. Pin outs for the
connectors are listed in Table 24 on page 56.
