<div class="logentry node-content">
<p>So this afternoon I went and changed the LV connection for INFN layer J0. I did it so the larger (heavier) LV source cables are now going into the top of the terminal (being supported by gravity) and the smaller (not nearly as heavy) LV at detector cables are coming in from the bottom of the terminal. Hopefully this mitigates or lessens the voltage shifts on this layer and ideally leads to less pedestal shifts. We'll have to keep an eye on it to make sure that the current output when all the APVs are configured shows reasonable values.</p>
