I have a UT+ It does 5V logic level pulses but I connect the TTL level PPS to a MAX232 chip which converts the levels to +/- 8 volts I think the problem is my long cable. I'm pushing about 80+ feet of cat-5 cable. Looks like I will either have to move the equipment or use RS422 drivers at each end. I'm going to try moving the equipment to where I can use a quality 4 foot cable. > Chris Albertson Redondo Beach, California _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
