# Using rtklib:

use str2str to send caster data to zed-f9p :
```bash 
sudo ./str2str -in ntrip://caster.centipede.fr:2101/LXLY -out serial://ttyACM0:115200:8:n:1:off
```
In another terminal retrieve the signal outputted by the reciever:

```bash
sudo ./str2str -in serial://ttyACM0:115200:8:n:1:off
```
the terminal output should look a bit like this:

```bash
