If you have an inverted TTL serial signal then you can connect it straight to n RS-232 port and there is a very good change it will "just work". They call it "TTL level RS-232". BUt if you want to reliable drive a long cable it is best to level convert to true RS-232. But today most "re-232" is actually using zero and five volts. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
