Hi, I made a cable for the GPSDO 2017 with CTS and original neo7m ,RS232's pin2 and pin3 to the ftdi RX/TX and no ground connected will receive the sats info, but u-center won't show the actual configuration, everything is unmarked like if the gps wasn't connected, cannot read or sens config. If I add the GND, (Pin5) in the GPSDO to GND in the FTDI, it stops even of receiving,just like dead, does anyone knows exactly what I need to do or someone with same 3 cables have it working (I think it should)
