serial communication ZMD310AT

hello,
I'm trying to communicate with a meter ZMD310AT through optical port and gives nothing.
-I have a head with ligei otica connected directly to a COM port and nothing.
-Already ligei attractions is the converssor USB/RS232 and also nothing
I have used a head-otica USB and nothing.
I just got results when I used the communication through the net.

Can you give me the settings for the parameters via serial communication

Sorry my english

here log comunication;

Hi,

Your parameters seems to be right. Try to set waittime bigger.
I believe it's 1 second. Try with 5 second. Handskaking might sometimes take time.

BR,

Mikko

I've tried everything
tested various speeds, times(like you said 5s and another) and nothing like you said.
With the connection type "net" all ok
with serial connection I can not successfully

The log file ;

Hi,

This is strange. Are you using Java or .Net client?

Have you try with GXDLMSDirector?

With some meters handshaking is little problematic because baudrate is changed on the fly, byt L&G meters usually work fine.

BTW: Try to set start protocol to DLMS with GXDLMSDirector.

BR,

Mikko
