This way there is no need to modify the commercial (CAEN) boards, and the signal integrity of the fanout board has been tested with a full crate, using the front panel clock/trigger connection. (Hall B - Sergey B.) The TI can be used in a '64x crate and it makes sense to use a '64x crate in this instance, because the VXS crate features would not be used by the CAEN TDC. If you wanted to use other JLAB VXS payload modules in lets say half the crate, you could still use the CAEN TDCs with the front panel clock/trigger fanout from the TI. <br><br>I have copied William Gu on this message since he was the designer of this fanout module and will have the latest documentation. <br><br>Keep me posted, <br>-Chris</blockquote></span></blockquote></div><div><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; 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; font-size: medium; "><blockquote type="cite"><br></blockquote></span></div><div><br></div><div><br></div><div><br></div><div><br></div><br><div apple-content-edited="true">
