(3)  Cautions 
  Check that the Ethernet cable between the controller and external device is 
connected correctly. 
  Use a cross connect cable if connecting the robot controller directly to an 
external device, and use a straight cable if the connection passes through a 
hub. 
  After making any parameter settings, turn the power off and then on again to 
enable the new settings.
