Encoders from Kit of Parts (Many Years Ago?)

[Mark McLeod]

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).
