Need help to read NMEA 0183 via FTDI

[jaapdub]

Need help from an electronics specialist to read NMEA 0183 via a FTDI (FT232RL USB To TTL Serial Converter).
I want to see the NMEA 0183 data that is send from my Actisense DST-2 module using a terminal program (TeraTerm) on my PC.
The problem is that I cannot get readable text although baud rate and other comm. settings should be correct. I see every second data coming in (from TX to RX on the FTDI) but it’s only displaying strange characters.
Connections between NMEA module (sender) and the FTDI is single-ended. So I connected:
- The TX (NMEA +/A) of the module with the RX of the FTDI
- GND of the module with the GND of the FTDI
On the web I see many examples (mostly GPS related) people doing comparable things.
What am I doing wrong? Thanks for all help!

Problem is fixed! Serial signal was inverted. I managed to read it by using an Arduino and the 'true' option in SoftwareSerial mySerial(10, 11, true); // RX, TX
