I followed the Niles ICS3 software step by step and still no results. The wiring diagram for the rs-232g I believe is incorrect, at least to work with the rs232 cable from RTI. The real problem is there is no way to get feedback from the Niles GXR2. It doesn't respond for some reason. If i send you the rs-232 strings i created we can compare and see if they are correct?
