User manual QSC AUDIO BASIS 922UZ

[. . . ] BASIS 922uz 8x8 CobraNet Enabled Control and Monitoring Signal Processor Hardware Manual *TD-000197-00* TD-000197-00 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 922uz supports up to eight channels of DataPort audio and amplifier status monitoring. This can be four 2-channel amplifiers or one 8-channel amplifier or other suitable combinations. 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 922uz 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 922uz is plugged into a properly functioning AC source. There is no power switch on the BASIS 922uz. This helps to prevent accidental system shutdowns. DIAGNOSTIC Indicator- This red diagnostic LED reports several possible operational conditions. During boot-up, it is used to continually blink a "dot-dash" pattern if the power-on memory self-test fails. During normal operation, if any non-recoverable system fault occurs, the diagnostic indicator will remain on, requiring a power restart. If this condition persists, contact QSC's Technical Services for assistance. The diagnostic LED is also used to indicate an update is in progress during a remote firmware update cycle. First, the LED will blink slowly, indicating the memory erase cycle, then it will blink rapidly, indicating the memory write cycle. During a firmware update, it is critical the unit remain powered on for the entire process in order to complete successfully. The diagnostic LED may also be controlled by using the QSControl. net software. This feature is particularly helpful for identifying a particular unit. (continued, next page) 15 LED Indicators (continued) QSControl and CobraNet Network Status (Port) Indicators- There are two groups 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 922uz receives data from the corresponding network. TX (transmit)- This indicator illuminates whenever the BASIS 922uz transmits data onto the corresponding network. LINK STATUS- The corresponding indicator illuminates when the BASIS 922uz is connected to an operating network. PORTS indicators- These indicators are labeled A through D. These indicators are either off, red, green, or yellow, depending on what is connected to the port.
