Hi Rick,
there are lot's of sites on the net with data you need, just use some
of search engines and you will find it (I did!).
There are couple of different cables and software so you must be sure
to match them.
If it is of any help this is standard connector description :
Pin Direction Description
=============================================================
1 Input RS-232 Shut Down Input (min. 4.5 s high)
2 Output RS-232 Line Fail Output
3 Output Normally Open Line Fail Signal
4 "Output" Common GND
5 Output Normally Open Low Battery Signal
6 Output Normally Closed Line Fail Signal

8
9 "Output" Chassis GND
