Electronics Forum | Thu Nov 05 10:02:54 EST 2009 | swag

Not all eX-feeders need a special procedure on the first connection to feeder base. It depends from firmware version. I received my new feeders two weeks ago - and they work from box without any special manuals like "hold the triangle button and jump
