Subject: CDS and Green locking thoughts 

Kiwamu and I went through and looked at the spare channels available near the PSL table and at the ends.

First, I noticed I need another 4 DB37 ADC adapter box, since there's 3 Pentek ADCs there, which I don't think Jay realized.

PSL Green Locking

Anyways, in the IOO chassis that will put in, for the ADC we have a spare 8 channels which comes in the DB37 format.  So one option, is build a 8 BNC converter, that plugs into that box.

The other option, is build 4-pin Lemo connectors and go in through the Sander box which currently goes to the 110B ADC, which has some spare channels.

For DAC at the PSL, the IOO chassis will have 8 spare channel DAC channels since there's only 1 Pentek DAC.  This would be in a IDC40 cable format, since thats what the blue DAC adapter box takes.  A 8 channel DAC box to 40 pin IDC would need to be built.

 

End Green Locking

The ends have 8 spare DAC channels, again 40 pin IDC cable.   A box similar to the 8 channel DAC box for the PSL would need to be built.

The ends also have spare 4-pin Lemo capacity.  It looked like there were 10 channels or so still unused.  So lemo connections would need to be made.  There doesn't appear to be any spare 37 DB connectors on the adapter box available, so lemo via the Sander box is the only way.

 

Notes

Joe needs to provide Kiwamu with cabling pin outs.

If Kiwamu makes a couple spares of the 8 BNC to 37DB connector boards, there's a spare 37DB ADC input in the SUS machine we could use up, providing 8 more channels for test use.
