In figure 23 of page 26 of the User's Guide, you show all the DIOs connected together through 10K pull-up resistors to one diode. Is there really only one diode, or are there actually 8 - one for each channel? I will be using external resistors pulled-up to 36V and I don't want the off (pulled-up) voltage at one channel to change when other channels turn on.

The diagram in the manual does indeed match the board’s circuitry. In the case you describe, the voltage at your off channel, when your other channel is turned on (taken to ground), would indeed drop a bit (the amount of drop would be proportional to your Load resistance in series with 2 of the 10K resistors).
