CMU CAM setup

Hi,
These instructions are really hazy to me, can someone explain which cables are connecting to where, there seem to be conflicting instructions, having this clarified would help me out a lot. thanks!:

Connect the RC programming cable to the Serial Communication Port,
(com port), of the computer and the RS232 PORT, (DB9) of the Vision
Sensor Assembly.

The instructions already said to connect the DB9 cable from the vision sensor port to the computer. and here it’s saying to connect the serial cable from the computer com port to the vision sensor again. why is this? Am I missing something in these sections? Where are settings for the computer’s com port changed. In the actual labview application? I’m using hte tutorial located here: http://www.kevin.org/frc/CMUcam2_workbook.pdf .

thanks a bunch,
Stephen
