Suntech device, not recognized

I have configured tk03 devices to use port 103 and suntech to use 5002
My device sends message to the 5002 port

However the server isn't even decoding the message.

Your device doesn't send any delimiters.

I believe the delimiter is sent, check the last character in the decoded message, but it's a character that isn't copied by my OS.

It's not there in your HEX data. Something doesn't add up here.

Oh the hex decoder was just decoding an extra newline character I suppose. What are the suntech devices supposed to send as delimiters? Because I don;t see the delimiter \r in the suntech document

I guess it's not specified in their documentation, but that's what all their devices use as a delimiter.
