I try many combination on client, logical, physical address and i think the current value is correct because the meter responding and responsive. What could possibly go wrong? Is it regarding the title, block cipher, etc?

Hi,

One of your settings is different from what the meter expects. The returned error code doesn't describe the reason why the connection fails.
