PEM models changed, spare ADC channels acquired by DAQ

Robert, Dave. WP5191

I modified all PEM models to use spare ADC channels for Robert's testing. At the end stations spare channels on the first ADC (ADC0) were fed into the PEM model. Since this is a lower ADC card than the one currently used, I replaced the current ADC0 part with ADC1, then added a new ADC0. The final configuration is ADC0=card0(the PCAL card), ADC1=card3(the PEM card). On the first ADC, PCAL is using channels 0-7 and 28-31. PEM is using channels 8-13

At the corner station things are easilier as PEM has three ADC cards and the last card has 11 spare channels (channels 21-30 were used)

All the new channels are acquired by the DAQ in both science and commissining frames at 2048Hz. The addition to the science frame is temporary pending a decision to permanently add them.

I have named the new channels H1:PEM-{loc}_ADC_{card}_{chan}_OUT_DQ where:

loc=EX,EY,CS 

card= physical card number (starting at zero)

chan = channel number (starting at zero)

h1pemex, h1pemey, h1pemcs and the DAQ were restarted.
