I have just created a new page containing information on the Icom 0 - 8V band-selection voltage, and instructions for making up cables to interface ACC2 (DIN) to the older ACC (24-pin Molex). http://www.ab4oj.com/icom/band.html As questions on this topic frequently arise, this page should be helpful. Cheers for now, 73, Adam VA7OJ/AB4OJ
