SoftwareVersionMismatch

So after switching a recalled brand new DP8K to an older model, I was successful in getting the console conected to the DP8K. Despite the show seeming to being running with no problems, I am getting a message on the display of the DP8K that reads "SoftwareVersionMismatch". This is displayed where it would normally say Output Active. The show is running, but what does the message mean?
