To understand the situation of the ADC cabling at the LSC rack I looked around the rack and the cables.
The final goal of this investigation is to have nice and noise less cables for the ADCs (i.e. non-ribbon cable)
Here is just a report about the current cabling.
At the moment there is only one ribbon-twisted cable going from 1Y2 to 1Y3. (We are supposed to have 4 cables).
At the 1Y2 rack the cable is connected to an AA board with a 40 pin female IDC connector.
At the 1Y3 rack the cable is connected to an ADC board with a 37 pin female D-sub connector.
The ribbon cable is 28AWG with 0.05" conductor spacing and has 25 twisted pairs (50 wires).
(things to be done)
- searching for a twisted-shielded cable which can nicely fits to the 40 pin IDC and 37 pin D-sub connectors.
- estimating how long cable we need and getting the quote from a vendor.
- designing a strain relief support
