DLMSDirector

Hi Mikko,

I am trying to connect to L&T ER300P meter through DLMSDirector. But my meter doesn't respond. I am certain it's due to some of my configuration. I tried Authorization mode None and Low with lnt1 password. But still no luck.

Could you please point me the mistake I am doing?

Thanks,

Hi,

Are you using an optical probe or RS-232/RS/485?

I am using RS485 port. I have RS485 to USB serial converter using that I have connected to meter.

Thanks,

Hi,

Check your cables. The reason is usually in cables or then the baud rate is wrong. Tryo to change the baud rate.
