Hello, how do need to connect and how I need to wire the board to the DB9 Port, if there some pictures available would be helpful, it should be AH 4 compatible.

Hi. How do I get the antenna tuning to work in thetis-hl2? 
I have io-board installed in hermes lite2 and hardrock50 with atu. In quisk it works very well. 
in thetis the io-board is checked but no reaction in atu when i press the tune button. i need some advice on what to do to get thetis to work with my atu in hardrck50? 
i have the newest stable thetis-hl2 version installed.
