Hello Edgardo --
The T2-Mini uses a wide-range input circuit based on one that Wenzel published with some modifications. It works with a square wave input (I've done some limited testing) but I can't verify whether the input amplitude range will extend as far on either the low or the high side.
If you want to drive with a true TTL signal, you could bypass the input circuit entirely and feed directly into the PIC, though that would require some soldering.
