    We made the following changes in the PVDIS setup:

    1. Removed Gr3 cables that were added in May 08 (see entry 271731).

    2. Restored the 37 ns cables from shower SUM8 to P/S 740 for Gr2, Gr6, and Gr7 (see entry 271004 item number 5 for when they were added).

    3. Added following types of delay cables in Gr1, Gr2, Gr3, Gr5, Gr6, Gr7, and Gr8:

    for shower SUM8 to P/S 740 : 16 ns for preshower SUM8 to P/S 740 : 48 ns for preshower SUM8 to medium threshold discriminator: 60 ns.

    4. For the "SC.and.notGC" veto part, unplugged the veto cable going from GC. Instead, took "notGC" from the GC-output and it was input to the 4th quad of P/S 755 as normal input and switched the switch selctor to "2" position.

    5. Added veto signals to Gr5 to G8. Now all groups have veto signals.
