Hi there,
OK, so the crate#1_slot#6_channel#8 is back!!!
I will move the SHV cable (#23 -> RCC1_B_2 -- Adam's HVGui convention,
RCC1_B_5 -- Adrian's and mine) to crate#1_slot#6_channel#5 tonight!
(i.e. the third bottom tube for the right middle size box -- second one)
Adam and Adrian please refer to this change from now on!
