Trying to connect xem7320 to szg-dac-ad9116.
I think the voltage of vio1 should be 1.8V, but xem7320 is providing 1.2V.
Verified that the value of SYZYGY0_PORT_STATUS is 120 in FrontPanel - Configure device settings - Device settings.
Should I change this value to 330?
So how can I change it?
thanks 
Hello and welcome to the forums!
The valid VIO range for the SZG-DAC is 1.8v to 3.3v.
First, add the XEM7320_SMARTVIO_MODE setting to the Device Settings page and set its value to 0. This sets the Smart VIO mode so that all present SmartVIO peripherals must result in a collective validation for any of the outputs to be enabled.
Then power cycle the XEM7320 and check to see if the issue is resolved (the VIO the SZG-DAC is on should be 1.8v assuming nothing else is connected). If it didn’t, please screenshot your Device Settings and post them here so we can get a better idea of what is going on. And confirm the SZG-DAC is connected to Port A or B on the XEM7320, both Standard Syzygy ports, of course.
