Could you recomend a signal level converter? I prefer a USB one.
Kind regards.
I have used these in the past in similar circumstances, search for USB-RS232-WE-1800-BT_0.0 for instance here.
This is the 1.8m version but there is a 5m one. The 0.0 at the end specifies a 0V power requirement which is right as you don't need to provide power, just the data connections. The datasheet is available on that webpage.
You'd need to use a ground and the 12V wires on your GPS to power it of course but for data connection, the Yellow on your device (RxD) goes to the Orange in the convertor (Txd), The Green in your device (Txd) goes to the Yellow in the convertor (Rxd). A ground is also required so black to black.
It is possible to buy a version of this cable which doesn't have the transmit/receive LEDs in the clear plastic USB housing but I like to see that stuff is happening.
There are of course cheaper options and equivalents but I have found that genuine FTDI chips are excellent and reliable.
