As reported before, PD1/2/3/4 on the ITMY baffle correspond to H2:PEM-CS_CHAN_30/29/28/27 and the MEDM screen didn't make any sense because of this.

The real issue should be some cabling somewhere (in-vac or out-of-vac), but instead of a proper fix I changed the medm screen.

PD1/2/3/4 still correspond to CHAN_30/29/28/27, but now MEDM  shows correct number at correct location.
