Just tried the same on a DS2202 (DS2072) hardware version 2, same result.
No CAN option and the 50 ohm input still greyed out. I wonder if it has something to do with these little jumpers on the pcb.

* Hardware Version of DS2000 is 1.0.2.0.0 and DS2000A is 1.0.2.0.2
* The type of the Serial number has changed from DS2Axxxxxxxxx to DS2Dxxxxxxxxx
May the Firmware recognize that?

There are examples of the DS2000A with each of these hardware versions:
Hardware Version: 1.0.2.0.0

Have you asked for a changelog?

Update: Tried downgrading FW....not working...OOPs

So you got a DS2202 with a new Firmware 00.02.01.00.03, right?
What are the FPGA version (SPU, WPU, CCU, MCU)? Any changes?
