AXF RS UNI with AXC F 2152 for a RS232 code bar scanner

Hi,

I am currently using a barcode scanner that uses RS232 communication protocol that's why we bought the AXF RS UNI 1H (2688666).

We installed Node Red on the PLC to program as little as possible on PLCNext engineer.

for this barcode scanner application we installed the library : AXL_ComSerial_9.

We have problems on how to programm it, look below, it’s the only thing we’ve done :

We don't understand why there is nothing Receive on arrRcvData :

Next to that, we looked that the frame is sent from our barcode reader and it's ok :

This is our module that we use : https://www.sparkfun.com/products/18088

It’s a 3.3V module, is it OK for the AXL RS UNI?

Can someone help us on theses issues ?

Thanks

    Can someone help me ?

    Thanks

    Update : I received data because uiRcvDataLength = 14. But i don't understand why i don't have data in arrRcvData.

    xRcvNDR turn from true to false immediately

    Someone knows why i can't see the receive data ?

    Thanks
