As Joe K1RQG points out to me, from the Atlas documentation it seems that C29 and C31 have been made intentionally different from most bus lines, for some reason. </div><div><br></div><div>However, this mean that the communications specification that we currently have for comm lines between Ozy/Magister/Metis and Mercury is invalid, as C29 and C31 fall in the middle of the 8-line comm spec that exists for that specification. </div><div><br></div><div>In Metis v1.1 and Ozy 6.3 I avoided use of the C29 and C31 lines and used A6 and A4 instead for those two sets of firmware. </div><div><br></div><div>It occurs to me that the two "missing" data lines (C29 and C31) of the 8-line comm spec could easily be the reason were earlier were plagued with strange audio "popping" phenomena. Lately many of the apps run using only a single NWire communication between the boards so the "missing" lines weren't important, until you try to use one of them for the NWire comm, hihi. </div><div><br></div><div>Sorry to put out a general alert but it sure looked like one was warranted to me at the time. </div><div><br></div><div>73, Joe K5SO</div><div><br><div><br><div>Begin forwarded message:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Helvetica" size="3" color="#000000" style="font: 12.0px Helvetica; color: #000000"><b>From: </b></font><font face="Helvetica" size="3" style="font: 12.0px Helvetica">Joe Martin K5SO <<a href="mailto:k5so@valornet.com">k5so@valornet.com</a>></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Helvetica" size="3" color="#000000" style="font: 12.0px Helvetica; color: #000000"><b>Date: </b></font><font face="Helvetica" size="3" style="font: 12.0px Helvetica">March 20, 2011 3:59:51 PM MDT</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Helvetica" size="3" color="#000000" style="font: 12.0px Helvetica; color: #000000"><b>To: </b></font><font face="Helvetica" size="3" style="font: 12.0px Helvetica"><a href="mailto:hpsdr@lists.openhpsdr.org">hpsdr@lists.openhpsdr.org</a></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Helvetica" size="3" color="#000000" style="font: 12.0px Helvetica; color: #000000"><b>Subject: </b></font><font face="Helvetica" size="3" style="font: 12.0px Helvetica"><b>Atlas bus lines C29 and C31</b></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; min-height: 14px; "><br></div> </div><div><br>Phil and ALL,<br><br>I have been beating my head against a wall trying to figure out why I cannot use the C29 and C31 Atlas bus lines between Metis and Mercury and tracked the problem down to what appears to be a fundamental problem with the Atlas board itself.<br><br>I have three Atlas boards, two assembled and tested and one new unassembled; all three show NO CONNECTIVITY between the connectors for both the C29 and C31 bus lines.<br><br>I believe this could be a design/fabrication fault with the Atlas board generally.
