We have two Nova V2F in 8-ID-I.
The left Nova V2F in att. 1 has PDBS , the right one has pind1, pind2, pind3 (IC1), pind4.
The two outputs on the V2F goes:
1) to the Joerger EPICS scaler
2) to the Joerger Display above bronze, model QVSC.
In the middle of the 8-ID-I rack, on the right, there is a board with 2 rows of 8 signals, these are
TTL-NIM converters. The inputs takes the output of the V2Fs and send them on the output to the
Joerger QVSC. So on this board, Input 4 is pind4, and input 5 is pdbs.
Finally Suresh has configured SoftGlue unit B here referred as SG-B input channel 6
to record the transmission detector. In vacuum it would be pind4, but Qingteng
wants to record the second ion chamber instead, so today we wired this.
The SG-B panel is shown in att. 4.
The SR570 PDBS unit (#5) is not responding. Using instead spare unit from Sec 26. Everything works,
except that the spare unit is not connected serially so at the moment only pind3 can be controlled in EPICS.
We set the same gain at 10 nA/V. The signal on IC2 is about 80% of IC1. I think I don't need to check the
impact of the T (kind of difficult to remove too).
