So D2000A is different from hardware D2000, right?

The only difference is that DS2000A has a 50 ohm input termination option.
But I think the DS2000 non-A version with HW 2.0 has this too, not sure if the PCB is populated with the 50 ohm termination.
Basically DS2000 with HW 2.0 seems to be the same HW as used by DS2000A.

I understand. We can not unlock version A, shows "only" with another, newer firmware?

Nice :-+
Does the DS2000 device options installed via the keygen still work after the FW upgrade?
Does the FW menu still say DS2202 or does it say DS2202A?
Can you downgrade to an older DS2000 FW again?
CAN Analysis kit does not come pre-installed on DS2000A:

--- Quote --- Decoding Options
RS232,I2C,SPI Decoding Kit SD-DS2000A
CAN Analysis kit(Trigger+Decoding) CAN-DS2000A

It is an optional add-on feature you can purchase for both DS2000 and DS2000A according to Tequipment:

g***!:
The model number is still DS2202 (not A), all keys still install/uninstall OK, but I forgot to try going back to a previous FW...Will do that now and report back!
Update: Tried downgrading FW....not working...OOPs
Panic over lol, now sucessfully downgraded again...Did'nt do it correctly first time. |O
Bugware:
So far I understand, there are at least two differences between DS2000 HW2 and DS2000A:
* 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?
