Does the 1998 Isuzu need another cable besides the OBD2 J1962 connector cable?

What is your question?

I have a Isuzu diagnostic interface pin out chart for the Isuzu's OBD2 port. It has a pin in the #2,4,5,9 and 16 slots. Going by the chart it shows that this is a J1850-VPW interface. The chart also describes the #9 slot function as ECM/TCM (GM8192 Protocol). Isn't that a ALDL Protocol and does that mean I need to use something more than just the OBD-II port male connector, or is that something a OBD-II scanner can pick up by itself? I am kind of new to OBD Scanners so I'm not sure what is what, or what will work.
