Short answer: you need a special cable.

Long diatribe: Despite the fact that they provide the software for
using their hardware with Unix, they didn't provide the cable that's
required (940-0023A).  Further, they refused to give me the pinouts
for the cable when I asked for them.  I figured out why when I got a
price quote for that cable: $80.  It's pretty disgusting behavior, if
you ask me, and has cost them a customer.

If you want to build your own cable, you can get the pinouts from a 
Google search.  But don't expect any help from APC.
