Encoders from Kit of Parts (Many Years Ago?)
 

I was running through inventory of our electronics and sensors, and stumbled across two sensors I cannot identify. The only markings on them are TTL-232 Rev NC and on the back is two different numbers on each encoder, CT0INV0273 and CTD00126491. Other than these numbers, they are completely identical.
I have tried googling these markings, but so far I have yet to find anything similar. I am pretty sure that they are not TTL-232 converters, because the only pins going out are 3 pins, and the two outer pins are labeled 1 and 3. The pin labeled 1 on the other side has BLK, which would have to go to that pin, as there is nothing else.
There is one capacitor, and 3 chips, one labeled U1, another CP1, and the other labeled B.

I don't have a cable to download the picture from my phone (my phone doesn't have internet on it) but as soon as I get it, I am going to add the picture to this post. Hopefully that will clear up any confusion on my description.

Anyone have any ideas of what these are? The only lead I have is our head mentor thinks they might be from 2003-2006 Kit of Parts, but I cant find any lists of what came in them. Thanks for any ideas.

I'm pretty sure it's a TTL level converter, since it's labeled as a TTL to RS-232 converter. :)
One came with the KOP in 2005, 2006 & 2007 , search for "TTL" (see photo IF114.jpg at the end of the 2007 list).
You may have been fooled by three additional pins that are recessed in a female connector at a right-angle to the male pins.
Does it look like this?

They were used in this fashion: http://www.chiefdelphi.com/forums/at...3&d=1108318123 & http://www.chiefdelphi.com/forums/at...2&d=1108318117
To connect a communication line to this CMUCAM: http://www.chiefdelphi.com/forums/at...0&d=1107365914

The 3-pin female connector attached directly to an IFI robot controller (TTL) while the 3-pin male connectors connected via PWM cable to the CMUCAM (RS-232).

Yes, that is what it was. Thanks Mark. As someone who only dealt with Crios, IFI control systems are foreign to me. But we still have 3 "projects" that all use them, even though we don't code them anymore. Now I know they aren't sensor though (I found them in a bag with gyroscopes, accelerometers, and 2 rotary magnetic encoders. I do no understand the organization of our last electronics guy....)
