Error,

So if you hold the card upside down so that pin one ins on the right. The switch settings look like this.

No, you have an error on address 2 - it should be 4-3-2-1 as on on off on

I think all the others are right.

Does it matter where the cards are on the back plane or just the address?

Here are the results from testing the I/O cards I have in this machine.

No, all backplane slots are the same. Only the address switch is needed to select the board address.

The bus test looks OK.

OK, to test the DIO cards with the diotest function, it will only test the DIO board at address 6. It will allow another DIO board to be at address 7, and set that one to slave to the one at addr 6. But, if you have more than 2 DIO boards, it doesn't know to select those ALSO to slave mode. So, I think the diag will only work with one or 2 DIO boards in the system, not 4. So, you will have to pull the extra boards out at least far enough so they are not plugged into the backplane. It may be simpler to just test one at a time.
Whatever DIO board is at address 6 will have to have the E-stop loop made to be a closed circuit, so the green LED is lit on that board. And, the DAC board in the system has to have the watchdog jumper set to off for the test to work.
