I contacted the vendor and they advised me to order a replacement card and send the defective one back for review. They also informed me that all boards were tested before shipping and most defects are user error. Now, I only connected what is shown in the pictures for a quick test and the card was not working from the start.

Can someone confirm if I made any errors connecting it? (Not to prove anything to the vendor but to save me from scrapping another card)

Looks OK, can you verify that you have +24V
on both VFIELDB pins?

I have 24V on the 5 pins to the left of the orange screw terminal.

There is information in the 7I97T manual (page 13)
for making a cable for any Sserial device (like the 7I84)

The 7I97T has a single RS-422 interface so can only connect
to a single 7I84 unless you add and additional expansion daughter
card (or simple 1 chip RS-422 interface) to the 7I97Ts P1 expansion
connector.


Do you have the drive and encoder pinouts?
