Hi all, We tested 8 RODS and found that in every case the Si1 line (which may connect thermistors from modules 1,3,and 5) is open. This was done by measuring the resistance across pins 3 and 16 on the 25 pin male connector on the ROD which also carries the HV bias lines. Furthermore, we tested the continuity from pin 16 to p1 on the ICC4\3 cards, and pin 3 to p3 on the ICC4\3 cards, and saw that they are connected properly. In the ICC3 card of Module 1 none of the p1-p4 pads are jumpered. Which means this Module's thermistor is not readout. However, in the ICC4 card for Modules 3 and 5, p1 is jumpered to p4 which shorts the thermistor on Module 3, also p3 is jumpered to p2 which shorts the thermistor on Module 5. This configuration still leaves the Si1 line open. If the Si1 line was meant to be left open then why short the thermistors on Mod 3 and Mod 5 while leaving the thermistor on Mod 1 unconnected? Is it even safe to have the Si1 line open in any case? If the jumpers on the ICC4 card were ment to connect the thermistors on Mod 3 and Mod 5 to the Si1 line, shouldn't they be connected in the following manner; p1->p2 and p3->p4 ? In our estimation the current jumper configuration ALSO leaves the Si2 line open, which is read by the DCU on the CCU. Regards, Ryan and Ricardo
