I was curious if all the GND
I was curious if all the GND lines are common grounds.
Yes, all GND terminals are
Yes, all GND terminals are the same thing and all connect to the same ground plane. Also see Section 2.3 about GND.
Note that the CB37 Terminal Board keeps pin 30 separate from the other 4 ground pins (pins 1, 8, 10, and 19). At the LabJack they all get connected to the same ground plane, but before that they are kept separate and pin 30 is called AGND.
Vendor, MPN, for mating connectors to the DB-15 and DB-37?
(Sorry - probably a pretty common question to the forum, but I couldn't figure out how to search for it...)
I want to put two through-hole male connectors, DB-15 and DB-37, onto my PCBA that will mate to the connectors on the LabJack U6.
Can some one suggest Vendor and Manufacturer Part Numbers for the connectors?
BR,
Kevin
These are very very common
These are very very common connectors so you will find lots of options, but I understand it can be daunting to just jump into an electronics catalog and try to drill down to the right variation of d-sub connector. One path is the follow the link on this page to the OEM section which has a couple female d-sub connectors listed at the bottom.
https://labjack.com/support/datasheets/u6/hardware-description/oem
These are both from the Norcomp 182 series, so I went to the Digikey information on that series and would up with this that seems to have some options for you.
DB15:
https://www.digikey.com/product-detail/en/norcomp-inc/182-015-113R181/18...
DB15 with boardlocks:
https://www.digikey.com/product-detail/en/norcomp-inc/182-015-113R531/18...
DB37:
https://www.digikey.com/product-detail/en/norcomp-inc/182-037-113R181/18...
DB37 with boardlocks:
https://www.digikey.com/product-detail/en/norcomp-inc/182-037-113R531/18...
The following page lists more female connectors from FCI and Sullins. These guide you to a family of connectors so you can then find male connector options in the same family:

Thank you..
..for the quick response.
