"Indeed, it is NOT true that the KAT500 uses TTL signal levels for the serial port. "
Ah, but I said "Isn't it true that the KAT500 USB cable uses RS-232 protocol but TTL signal levels? " Perhaps I should have been more specific. My recollection is that the USB/Serial cable transmits a TTL signal. I have no way to know the receiver characteristics of that interface dongle. I did study the KAT500 I/O schematic to understand that end of the connection. Anyway, not posting to "keep you on your toes". I was confused by this interface when I first decided to work with it so didn't want people to assume it was RS-232 compliant. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
