Cannot Communicate with Hexing Electric Meter

Thank you for the quick reply.

The converter is powered from an external 5V power supply. Serial port setting are 9600 8N1. The manual for the meter specified 8-bytes as password so I am using 00 00 00 00 00 00 00 00. All other settings are as specified in the initial config page for HEXING. Is it possible n incorrect client ID could cause this?

Hi

Thank you.
I will inquire from the vendor.

Hello,

Following the search for the right client address, I got the following from Hexing.

Sub station No: Generally it is “01”, it is the logical address of meter. "For protocol DLMS(Mode E) the length of sub station No. is 1 byte, but for DLMS(Direct HDLC for RS 485) it is 4 bytes which is the last 2 bytes of the meter serial number in the nameplate add „0001‟.

Now the client address in DLMS Director can only accept one byte. Is it possible to use another Gurux project instead of DLMS Director (perhaps the Arduino Gurux Server or Client ) and which would accept the 4 bytes?

Thank you

I have the serial number in question but the the

I have been able to resolve this. The IR from the meter was not 38Khz modulated and I was using a 38KHz receiver. I made an IR transceiver with IR LED as sender and IR Transistor as receiver with some amplifier circuitry and it works perfectly with GXDLMSDirector.

Thank you for the support

Yes,
For the optical to work the IR sensors i noticed the following
1. The sensors need to be no more than 0-5mm apart even out of sunlight. I made two to confirm effectiveness.
2. The presence of infra red from other sources like sunlight or other red light could corrupt data.
