I'm looking for some help, in implementing the DRM function of the flex. based article. I have a flex 1500 I read that knowledge based article and they suggested I use windrm software. It wasn't clear at all how to program the sound card portion of the windrm. Also, the way the cable should be hooked between the two sound cards, and I have been using the VAC 1 port for sound outport on the HF function and can I use the VAC2 port as well? I also have the dream software.
