4Xx Roomba Intermittent Control

Hey everyone. I am working on a couple small bots for the rainy days of the summer. I am trying to create a couple of those minions from Despicable Me movie. Very basic I am using roombas for the base..

I just hooked up to my old grey one making sure (with ocd) that I had the pin out correct, to the EZ-b board. It communicates with it intermittently. I try and move forward or left, right etc it does sometimes and then I try something else and it won't follow the command. Well except for off it likes the off command.

Has anyone run into this?

Thanks Jason

How far away is the Roomba w/EZ-B from the PC ?

Hey Doc. Its sitting right next to it on the bench. I am using the old protocol, and port 0. That reminds me I have to order a cable from you sometime.

That old grey one is probably a Disco model so you've got the right setting. I wonder if there is a poor connection on one of the two leads of the plug ? Also, how are you powering the Roomba and EZ-B ? Both power sources need to share the same ground.
