Hi,
I have a CEWE Prometer 100 meter which I am trying to read data from using GXDLMSDirector. I can access the meter successfully using level 1 access (LLS). However, I am unable to access the meter at level 2 (HLS).
I know the level 2 password is correct as it works on the M-Cubed software.
The level 2 password for the meter is 22222222, so I am putting 30303030303030303030323232323232 as the password when using GXDLMSDirector.
I was told by the manufacturer that the random number sent by the meter should be encrypted with the AES-128 algorithm. Do I need to configure GXDLMSDirector to do this?
This is the comms stream with level 2 access:
GXDLMSDirector 0.0.0.0

Hi Andrew,
You can give the password as it is. Try to set the password (22222222) as plain text.
Now you are using password 0000000000222222.
I believe that this is the problem.

Hi Mikko,
I have literally been looking at this for an hour and the problem all along was the padded password only had 6 '2's instead of 8 :).
Thanks for your prompt response which highlighted the problem perfectly. It doesn't work with 22222222 but it does with 0000000022222222.
Thanks,
Andrew
