RS232 Serial port to TTL digital converter module: Does this device work?


im using this device in order to communicate with a RS232 sensor (im using an Arduino MEGA):

As I understand from the specs it should convert RS232 signals to TTL and TTL to RS232, so communication from both sides should be possible, right?
Does anyone have experience with this particular device and arduino?

Thank you!

I have used this RS232 to TTL converter with an Arduino mega OK

which serial port are you using?
if you are using Serial1 check you have pins 18 and 19 connected to the correct signals
pin 18 is the serial transmit from the arduino, i.e. Serial1.print()
pin 19 is the serial receive, i.e.

do you know the baud rate of the RS232 sensor?
