I am sure that the above works fine, and is probably better in the long run than the following. If you don't want to ruin a PWM cable or perform any sort of "hack" on the thing, plug stuff in as follows:

You will need:
•4 PWM cables. 3 pin each, male-female.
•1 TTL-RS-232 adapter (comes with CMUcam)
•Free TTL Port
•2-4 other free PWM ports on EduRC

What to do:
•Connect a PWM cable from the TTL port on the EduRC to the closest 3 of the 4 sockets on the TTL adapter towards the RS-232 out pins. (just follow Black to Black)
•Connect the black socket of one PWM cable to the middle pin (+5v) of a free digital in/out PWM on the 2004 eduRC. Yes, you have to plug it in sideways. I suggest taking up 2-3 ports so that the cable doesn't fall out.
•Connect the respective pin of that cable to the free socket on your TTL adapter (towards the edge, NOT the B. Again, you WILL have loose pins floating out in space.)
•Connect a PWM from the RS-232 out on the TTL Adapter to the RS-232 PWM in on the CmuCam2 board. Plug Black into B as always.
•For power, connect the last PWM cable from another free PWM socket on the EduRC to the cmucam. (to the port near the power switch).


Works for me. (and I didn't even have to risk loosing a PWM cable!)
