I received the ítem in the forecasted delivery time. A bit later, due to the Christmas Periode and several bankholidays included on it. Satisfactory anyway. I had the problem of programing the tariff periodes, so I asked and receive a fast answer how to proceed. Answer was very concise but proceeding in a logical way I succeed to program the times without damaging anything. It's true that I would have preferred instrucions as: 1)Adjust SDM220-MT at the values shown in EEM_MeterSet.exe 2)Connect RS232 Pin 2 to SDM220-MT output 9 (A+); Pin 3 to output 8 (B-) and Pin 5 to output 7 (GND). Add T1, T2, etc values on the table and confirm them. After seing a phone handset symbol you will have programmed the times inside. I'm at this point. Now I have to connect the SDM220-MT to my dashboard and see what happens. Probably all wil function as expected.
