C7-621 V1.1 or V1.2? Also: Expansion 15 D-SUB?

[e5frog]

Hello, was about to use STEP7 for the first time with a C7-621 (PLC+display unit).
When choosing unit I'm getting to 6ES7621-1AD02-0AE3 but then the program wants to now if it's V1.1 or V1.2, how do I know which type mine is?

Does it have anything to do with the MECH, GRBG and PER markings on the label on the back? Does it need to be decoded from the second bar code?


Maybe I can also squeeze in another question...
The 15 pin DSUB that goes from the C7-621 to the PLC extension modules, is it a straight 1:1 cable or is there anything special about it? What's the original called? Is anyone selling these?

Thanks, best PLC forum!
