Hello,
I want to read an energy meter using its RS232 port with GXDLMS Director.
The meter I am using is L&T EM101+ DLMS Cat C3 IS15959.
I do not have a RS232-to-USB cable with a DB9 connector right now. I have a MAX3232 RS232-to-TTL converter and an FT232RL USB-to-TTL module.
My idea is:
Meter (RS232) → MAX3232 → TTL → FT232RL → USB → GXDLMS Director
Will this work?
Can I convert RS232 to TTL using the MAX3232, then convert TTL to USB using the FT232RL, and read the meter normally with GXDLMS Director?
This is the FT232RL USB-TTL module I have:

And this is the MAX3232 module:

I know that a simple RS232-to-USB converter cable would work and it is cheap, but I don’t have one at the moment. I also want to try this setup out of curiosity.
Please let me know if this setup is OK and if there are any special settings I should use.
Thank you.

Hi,
Please, buy the ready cable. Cables are causing so many problems. It will save so much of your time.
