Can the PCI-6602 card be configured for 3.3 volts?

[jisaacs]

I would like to be able to configure my pci-6602 card to output 3.3 volt signals either in software or with MAX. Can this be done?

Hi,

Unfortunately, this is not possible. You need to create an external circuit that will step down the voltage for you.

The 6602 uses only 5V logic for it's driven outputs, but there is a Tri-State Enable feature which drives the output to high impedance instead of hi. This allows you to pull up the outputs to the required logic voltage.

The Tri-State Enable is found using the wired OR map in the DIO Port Config.vi

The 660x devices do not have Tri-state capabilities. Only the 653x devices are capable of this.
