[. . . ] BASIS 904zz 16 Output CobraNet Enabled Control and Monitoring Signal Processor Hardware Manual *TD-000152-00* TD-000152-00 rev. A IMPORTANT SAFETY PRECAUTIONS & EXPLANATION OF SYMBOLS The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous" voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in this manual. SAFEGAURDS Electrical energy can perform many useful functions. This unit has been engineered and manufactured to assure your personal safety. [. . . ] The 904zz supports up to sixteen channels of DataPort audio and amplifier status monitoring. This can be eight 2-channel amplifiers or two 8-channel amplifier or other suitable combinations. If connecting a multi-DataPort amplifier, ensure all the DataPorts of the amplifier are connected and that they are all connected to the same BASIS. To connect the cable, orient the connector properly, then push into the receptacle until it is firmly seated; tighten the retaining screws "finger tight". LED Indicators When the BASIS 904zz is plugged into a properly functioning AC outlet, it will power up and briefly display a welcome screen on the LCD display. POWER Indicator- This blue indicator illuminates when the BASIS 904zz is plugged into a properly functioning AC source. There is no power switch on the BASIS 904zz. This helps to prevent accidental system shutdowns. DIAGNOSTIC Indicator- This red indicator illuminates during the power-on self test, then should extinguish. If it remains illuminated, this indicates that the self-test has detected an unexpected event, such as corrupted firmware or a memory boot failure. If the DIAGNOSTIC LED remains illuminated, try resetting the BASIS 904zz by cycling power off and on once. Should the indication persist, contact QSC's Technical Services for guidance. During operation, any system fault will fully illuminate the indicator. During a "flash" update, the indicator will blink on and off; this is normal. Any error detected will be displayed on the LCD. For purpose of unit identification, the LED can be remotely turned on using QSControl. net software. (continued, next page) 15 LED Indicators (continued) QSControl and CobraNet Network Status (Port) Indicators- There is a group of three LEDs on the front and rear panels labeled RX, TX and LINK. One group is for the QSControl network port and the other for the CobraNet network port. Note: Port indicators on rear panel are color coded to match the corresponding color-ring around the QSControl and CobraNet RJ45s. RX (receive)- This indicator illuminates any time the BASIS 904zz receives data from the corresponding network. TX (transmit)- This indicator illuminates whenever the BASIS 904zz transmits data onto the corresponding network. LINK STATUS- The corresponding indicator illuminates when the BASIS 904zz is connected to an operating network. PORTS indicators- These indicators are labeled A through H. These indicators are either off, red, green, or yellow, depending on what is connected to the port.
