--->DTB 154 (one of the red cold box setup):
- flat cable (with HV):
>adctest
clk low = -231.0 mV high= 212.0 mV amplitude = 443.0 mVpp (differential)
ctr low = -246.0 mV high= 235.0 mV amplitude = 481.0 mVpp (differential)
sda low = -250.0 mV high= 223.0 mV amplitude = 473.0 mVpp (differential)

sdata2 low = -173.0 mV high= 149.0 mV amplitude = 322.0 mVpp (differential)
- twisted pairs cable:
several ERRORS during VthrCompCalDel and PixelAlive: ERROR: <datapipe.cc/CheckEventID:L486> Channel 2 Event ID mismatch: local ID (119) != TBM ID (120)
>adctest
clk low = -196.0 mV high= 177.0 mV amplitude = 373.0 mVpp (differential)
