Round 3 ....
So the meter we have comes with a software package and that happens to log "frames" that it sends and recieves from the meter.
These are DLSM/COSEM - ASN 1 frames but i had a look through and noticed a few patterns...
Im attaching the frames and the analysis text files so everyone else can have a look and maybe pitch in.
Note: please use notepad++ for the analysis file as it contains non-standard ascii characters (SOH STX ETX etc...)
