SUS Model Updates: h1susitmx

Jeff, Oli

We made several updates to multiple SUS simulink models as a continuation of our work converting SUSB123 and SUSH34 into SUSB13 and SUSB2H34 (88765). Our changes were based on our updated G2301306-v10_PARTII - for the conversion from SUSB123 into SUSB13 for ITMX, we referenced slides 5, 7, 12, 13, 18, and 19. These changes were svn'd as r34388 and were installed and started last week (88781).

These are the changes we had to make for h1susitmx:

CDS Parameter Block:
- Changed hostname from h1susb123 to h1susb13
- Removed specific_cpu

Input (before, after):
- Removed ADC1 since now all OSEM channels are on one ADC (called ADC1 in diagrams)
- Redid ADC to OSEM configuration
- Changed name of SHMEM channel that comes in for ITMX L3 BIO
    - Previously was H1:SUS-ITMX_BIO_L3_MON_SHMEM, now is H1:SUSITMY_2_ITMX_L3_BIOMON_SHMEM

Output (before, after):
- Changed DACs from several 20 bit DACs to two 28 bit DACs
- Lined up outputs to their corresponding DAC channels
- Lined up ESD bias and ESD sum outputs to their corresponding DAC channels
- Changed name of SHMEM channel that goes out for ITMX L3 BIO
    - Previously was H1:SUS-ITMX_BIO_L3_CTRL_SHMEM, now is H1:SUSITMY_2_ITMX_L3_BIOCTRL_SHMEM
