I have SL7000 meter and GSM Modem iRZ. When i send by using RS-485 cable - everything work. But when i'm trying to use GSM modem i'm getting issues. When i send SNRM like this: 7E A0 0A 00 22 00 51 03 93 6A 34 7E I get normal UA. But when i try to send SNRM like this: 7E A0 21 00 22 00 51 03 93 6B 21 81 80 12 05 01 80 07 04 00 00 00 02 08 04 00 00 00 01 3D 93 7E (It's from DXDLMSDirector) I get nothing. Absolutely! Maybe there is some trick to use hdlc with gsm modem? Maybe special delays or something?

If both of these frames work via the RS-485, and not via the GSM, then there are a couple of possible answers: 1) the addressing you are using is not permitted if this is a seperate port 2) if it is the same port on the meter, then the GSM Modem is not directing traffic to the same RS485 address
