A Tek 1720/1730 pair are replacing the original Tek 528/1420 setup in the sidecar.</div><div><br></div><div>In connecting the wiring harness... we have a round 9-pin plug that went to the 528... (pictured) and no matching connector on the 1730.</div><div><br></div><div><img height="258" width="244" apple-width="yes" apple-height="yes" src="cid:5A3E6BA5-60EB-454E-AF44-20451CA607EF"></div><div><br></div><div><br></div><div>The VPR-80 manual harness diagram shows that one of the two wires between the QC switcher and the scope connector is a "Sync Ctl" line. </div><div><br></div><div>The other has -15 Volts (from the scope?) and goes from SubD Plug 9/Pin6 on the switcher to pins 2, 6 and 9 of 9-pin plug called P370 on the scope.</div><div><br></div><div>It appears to change the scope's sync input when switching from video to Demod or AST Error modes.</div><div><br></div><div>So, my question is... what pins do we use on the 1730 to accomplish the desired functionality?</div><div><br></div><div>Please e-mail a reply that includes off-list to <a href="mailto:ted@flashscan8.us">ted@flashscan8.us</a>. </div><div><br></div><div>I'll get it on my iPhone more quickly. Am putting the package together now for delivery tomorrow. </div><div><br></div><div>Thanks much in advance.</div><div><br></div><div>Will post pix with the results.</div><div><br></div><div>Ted</div><div><br></div><div><div apple-content-edited="true"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; font-size: 14px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 12px; ">Ted Langdell</span></font></div><div><span class="Apple-style-span" style="font-size: 12px; ">Secretary</span></div><div><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 12px; ">Skype: <span class="Apple-tab-span" style="white-space: pre; "> </span>TedLangdell</span></font></div><div><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 12px; ">e-mail:<span class="Apple-tab-span" style="white-space: pre; "> </span><a href="mailto:ted@quadvideotapegroup.com">ted@quadvideotapegroup.com</a></span></font></div></span></div></span></div></span></div> </div><br></div></body></html>
