Downdraft design questions

Man, he released that just after I got my card wired up!

Ha, so I take it you didn't do the unnecessary connection to VIN then. There are some advantages to not having a schematic one can follow blindly.

VIN should not be used as it can be disconnected with the jumper, use the 8-32V pins on TB1 for powering the board.

Like this? Or does the -24 need to go somewhere else?

Ok, just for the record: There is no -24V here.
I get that you refer to the negative terminal of the 24V DC supply but lets call the positive terminal 24V and the negative terminal 0V or GND.

Now you're missing the power for the FPGA. So go back to the schematics before and just move the 24V from the "VIN" Pin to one of the "8-32V" Pins below that and bob's your uncle.

In other words:
TB1 : Pin8 < GND, Pin4 < 24V
TB3 : Pin23 < GND, Pin22 < 24V

So exactly like Norbert's schematic, except TB1 Pin5 should be Pin4 (or 3,2,1)?

How does this look?

Yes, that looks good to me.
