The cable has only two pins/leads.  This means it will not
map cleanly to an rs232/rs422 serial port that your computer
uses, and you will need custom circuitry in between to translate
the voltages.  If you have an oscilloscope, you can figure out
what this mapping is, but it's probably beyond the non-technical
amateur to try.

(I'd do it, but I'm not in hardware anymore, and don't have access
to a 'scope).  So you should probably just pop the bucks.
