QSC Audio RAVE 81 Benutzerhandbuch

The eight status indicator LEDs display the operating condition of the RAVE unit and its

Ethernet network. They are color coded such that green LEDs, when lit, signify something

good or normal, while red ones signify a problem. The “Conductor” LED is yellow because

it doesn’t signify good nor bad; it’s simply informational.

This LED lights green when the unit is properly connected to an operating Ethernet network. In normal operation,

this LED remains constantly lit, as long as the circuitry detects the network carrier.  If this LED is not lit, there

is a fault, probably at the hub or in the connection between the RAVE unit and the hub.

This LED lights green when the unit is connected to a 100baseTX Ethernet. If it does not light, the network either

isn’t established or is a 10baseT Ethernet, and the RAVE system will not work.

This green LED lights for 50 milliseconds or longer whenever the unit receives Ethernet data, whether it is

addressed to the unit or not.

This red LED lights for at least 1 second if the unit has trouble receiving a channel for one of the following reasons:

◗

Ethernet data or framing error.

◗

Network timing error; typically caused when transmission is delayed by unregulated traffic on the

network.

◗

An internal fault has occurred. The fault indicator will also light in this case.

This LED lights green for at least 50 milliseconds while the unit is transmitting Ethernet data.

This LED lights red for at least 1 second if unit is having trouble transmitting data for one of the following reasons:

◗

An internal fault has occurred. The fault indicator will also light in this case.

◗

The RAVE unit is not connected to an operating network.

This is the aforementioned yellow LED. It lights whenever the unit is the conductor, i.e., it is providing master

timing and coordination services for the network.
