MOXA Ethernet to RS232 For Arduino

Hello

 

I am working on something a little bit specific... I hope you could help !

 

I am using Labview --> Moxa Ethernet to RS232 -->MAX323 (to TTL 5V)--> Arduino UNO

 

What I would like to do first is a simple application : control the led ON/OFF (pin 13) via Labview.

As I use the MOXA, I guess I need to use VISA because the Arduino is not seen as a COM port anymore... But I can't find a way to send something via pin 0/1.

 

Could you help me ? Is that possible to do ?

Thank you !

When I run my VI, I can see the TX light on the MOXA ON, so I think my issue is more on the arduino side...
