    238 Ensure the localhost field is set to ''localhost:5002''. (Recall from the set up section to create a tunnel from localhost:5002 to sdr2-lg1.sb1.cosmos-lab.org:9002 since the ''app_read_sdr_samples'' application has a websock server listening on that host:port.)
    239 Ensure the device type field is set to ''type=x300''.

    241 
    242 Click the ''connect'' button once and a "Websocket Connection" statement should be output by the application.
