Hello,
In the IVY manual you have options for 2v and 4v COD output. I am wondering how to set this. The datasheet shows two output stages, one 2v and one 4v, but I don't think that is what you are referring to. Is this done by setting the output resistors or is it software (switches)?

Thanks!

Rereading the manual, it looks like you set the jumpers on the IVY and they dictate the voltage out of the COD. Right?

Yes. The COD is a current-output DAC. The voltage is determined by the I/V (current to voltage) resistor values used.

I have the COD and have soldered in the resistors and the caps. I planned to use the onboard I/V stage but have now bought a IVY stage instead.
I have also soldered in the jumpers to bypass the caps in order to use the new IVY stage. Do I have to remove the onboard DALE 392R resistor at the COD I/V as well?

Regards

Yes, it is best to remove them.
