Filiberto fixed the working 36/45MHz WFS, S/N 1300511. He extracted pins from the 5-coax connector, rotated the connector shell by 180 degrees, and inserted the pins again such that the connector looks like the mirror image of its old self. Since it's the mirror of the mirror, now it's correct.

I rerouted the cables inside the ISCT1 so the connections from outside of the table are still intact.

Connected the diff-single converter out 3 and 4 to the MCL PZT driver.

ISC R1, position 2, channel (3, 4) = H1:ISC-(434, 435) cable = MCL controller (X, Y) channel on ISCT1.

DAC works.
