[iw9gtd]

hello
I can not connect to ham radio deluxe ic 706 com2 I installed it on the radio remote-rig a level converter home made, I configured serial com2 as c-iv, speed equal to that set on the menu of IC706.
later on the remote-rig controller  I configured the serial com 2 as civ, I connected to com2 serial cable pin to pin, but ham radio delux does not recognize the radio
thanks bye the iw9gtd
