New firmware version 1.07 adds useful feature to the second TTL CAT port of the radio. All CAT inquiries sent to main USB CAT port now are answered on both ports so second TTL CAT port can control external devices with CAT control feature like linear amplifiers, automatic antenna tuners, smart antenna switches and other. And all this is possible during normal CAT communication between the radio and PC . Special CAT command – AI (Auto information) can be used If there is no connection between PC and RGO ONE. AI command can be adjusted to send viable data (frequency, mode etc.) on frequency/band change or periodically.
Second CAT port (TTL 3.3V) is wired on rear DB15 Cannon connector. Only three lines are in use – GND – pin 4, TX – pin 5, RX – pin 6.
