There were the guys who used the PENTEK 40pin connectors into the IDC 40pin connectors.
Those connectors are not compatible at all.
==> We replaced the connectors on the cables from DAC to IDC adapters to the dewhitening board for the vertex SUSs.
In addition, I found one of the Binary OUT IDC50pin connector has no clamp.
==> We put the IDC50pin clamp on it.
PENTEK connectors were inserted. The latches are not working!
the vertical pitch is different between PENTEK and IDC!
Wow! Where is the clamp???

The cause is apparent! The connectors on the cables are wrong!
Currently only 50% of the pin length goes into the connector!

We found one of DAC cables had a poor contact.
That probably caused our too much "tilt" of the beam into MC.
It was because one of the DAC cables(labeled CAB_1Y4_88) had a poor contact.
If I push it really hard, it is ok. But maybe we'd better replace the cable.
What caused a poor connection?:
I don't know.
A month ago, we checked that they are connected, but things change.
