ASC1 TX and RX swapped ? (EHS6T USB) | Thales IoT Developer Community

Hi, im experiencing something odd with the EHS6T (USB).
When connecting the arduino uno TX (pin 1 on the arduino) to the EHS6T RXD1 (pin 4) there is no communication from the arduino to the EHS6T. But if I connect the arduino TX pin to TXD1 (pin 3) then communication works flawlessly.
Other connections performed are:
Arduino GND ---- EHS6T GND (pin 2)
EHS6T VCCref (pin 1) ---- EHS6T +5Vout (pin 7)
Is this a normal behaviour ? Im using RS232Demo.jar ("comm:COM1;blocking=on;baudrate=115200") as a base for the program (reading with inStream.read();).
