Hi,
Hi,
The meter doesn't reply because of:
1. Wiring is wrong.
2. Your baud rate is wrong.
Check those. You can ask for the correct baud rate from the meter vendor or meter manual.

This is the meter RJ11 pin
This is the meter RJ11 pin definition received from the manufacturer and now done the handshaking on the DB9 connector, still after connections to the meter, setting parameters (Baud rate - 9600 , Parity - None, stop bit -1, Data bits – 8 , authentication password – ABCD0001) and when I have open the utility still "refresh" button is inactive.

Do I have to add OBIS codes
Do I have to add OBIS codes in the Tools section for secure meters Ltd.
Hi,
Hi,
All objects are read after the connection is established for the meter. You don't need to add anything.

Hi,
You need to press Connect to establish the connection to the meter. Refresh-button is activated after the connection is established.

Hi Mikko,
Hi Mikko,
I am not able to establish the connection on the meter. I have the Secure Premier 300 3phase energy meter. I am taking CRO snapshot of Tx and Rx pin on the meter RJ11 port after I press Connect and it transmits some packets, and after that it shows "Disconnect Mode" OR "Invalid Header Checksum". Both screenshot attached
I am taking the Client Address(0x14 or 20), Logical(0) and Server Address(1), Authentication- LOW (ABCD0001).
So why Disconnect mode is showing. Can you please explain.
Please suggest.
Regards,
Kartikey

Hi,
Hi,
The meter sends invalid data. One byte is missing. I know that our clients are reading SECURE Premier 300 meters. You need to ask if there is a firmware update available for your meter.
You can try this: Select "Frame" tab and change payload size from 128 to 512. Then try to connect again

Hello, A question. Can I use…
Hello,
A question. Can I use RS485 to read from the meter using the RS485 extension for Secure Premier 300?
What is the default address of the meter?
Can you share the Modbus address mapping?
