I have a UT+ I bought a TTL-RS232 converter on eBay the converter is built into a DB-9 socket. It uses male header pins for conniption, the same kind of pins as on the UT+ Look at item # 330838910970 on eBay. It is almost exactly what I have, lots of people sell them. It is just the max232 chip but the packaging looks clean and easy to use.
But as I remember I had to use at least one inverter gate. I forgot why maybe to drive the PPS or the LED I wanted to add. I don't have a VE2ZAZ board. I was using the UT+ for NTP server. My next project is to build a GPSDRO (GPS Disciplined Rubidium Oscillator) I could likely count the 10MHz output for 10,000 seconds.
