WHAM2 & 3 GS13 Switching now seamless and successful

WPs 7770, 7749, FRS 11049.  DaveB, RichardM, JimW, HughR

Conclusion--Yes the model and the hardware were at cross purposes as Interface Chassis 1 had GS13s corners 1 & 3 while the BIO switching via the model thought it was corners 1 & 2.

Details:

Rewired the interface chassis for HAMs 2 & 3 to have corners 1 & 2 GS13s  to chassis #1 and corner 3 to go to chassis #2 (switched cables 2 & 3.)  Rewired the top level models for HAM2 & 3 to reflect this field wiring change.  Dave also swapped out the deprecated digital IO cds RCG part with the current latest version.  Removed the GS13INF_OUT channels from the DAQ list in the common model and the one occurrence of "DACKILL", an annotation element.  There should be no more user model DACKILL parts.

After Dave rebuilt, checked etc, and the model was restarted, ran the ISIs in DAMPED mode and toggled each digital filter on the GS13s.  No problematic wildness occurred.  Then ISOLATED the platform and used the commands scripts to toggle the filters--all good.  Finally, changed the Guardians to include the GS13 switching--the GS13s switch to high gain whitening off after isolating and switches back when deisolating or tripped.  Exercised the platforms via the guardian and no issues; the GS13 change state with out bothering the platform much less tipping them violently.

Finally.
