On the connector are two LEDs. The left LED (IN USE/CONDUCTOR) lights yellow when the port is in use and will 
blink if the device is also the conductor (the CobraNet timing-master device). The right LED (LINK/ACTIVITY) lights 
green when link is established and blinks when network activity is detected. Both LEDs flash yellow in unison to 
report a fatal error.
