flashes.
3. CONDUCT LED Indicates the CAB 4n is an active conductor on the CobraNet network.
Only one conductor is allowed per network.
4. LINK LED Indicates a valid control link has been established between the CAB 4n and
the network switch. This function is duplicated in the software control panel.
5. RX LED Indicates the presence of data being received into the CAB 4n from the
CobraNet network.
6. TX LED Indicates the presence of data being transmitted (sent) from the CAB 4n onto
the CobraNet™ ne twork.
7. AUDIO METERS Peak reading LED ladder displays indicating audio input/output levels
in the analog domain. Signal level is displayed after the adjustable gain stage and before
the A/D converters.
8. POWER LED Indicates that the CAB 4n is powered from an AC mains power source.
9. IEC POWER CABLE RECEPTACLE The included removable IEC power cable
