DLMSDirector

Hi,
I am used ER300p energy meter(L&T). It is a Indian Standard meter. I am used optical cable to read the dlms data using GXDLMSDirector.
I have get some data from the GXDLMSDirector. After some time, its given a error was fail to receive reply from the device in given time. I was not found data of KWh, KVArh and other. I have attached the screen shot below.
Same question ask the other person, you said Try to change the authentication level from None to low or High.How to find authentication password, I do not have any manual ?
Please help me, I am beginner in dlms.

Hi,

I believe that you are right. You need to change the authentication level. You need to ask password from the meter vendor. It can be anything.

Reason why you are receiving failed to receive reply error is that there is an inactivity timeout on the meter.
Change inactivity timeout from the "Advanced" tab on the meter settings.

Hi Manish,

TCP/IP is the default connection type. Change media to serial from device settings.

Hi Manish,

Does this error occur when you make the connection or when you try to read data from the meter?
What you try to read?
