[. . . ] BASIS 922az 8x8 CobraNet Enabled Control and Monitoring Signal Processor Hardware Manual EN EN *TD-000133-00* TD-000133-00 rev. B 1 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. This unit has been engineered and manufactured to assure your personal safety. Improper use can result in potential electrical shock or fire hazards. [. . . ] Communications should be 9600 baud, no parity, 8 data bits, 1 stop bit, and flow control Xon/Xoff. When using the BASIS 922az with QSC DataPort-equipped amplifiers or QSC DSP products (DSP-3, DSP-4) connect to the BASIS 922az using QSC DataPort cables. The 922az 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 922az 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 922az is plugged into a properly functioning AC source. 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 922az 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. 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 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 922az receives data from the corresponding network. TX (transmit)- This indicator illuminates whenever the BASIS 922az transmits data onto the corresponding network. EN LINK STATUS- The corresponding indicator illuminates when the BASIS 922az is connected to an operating network. These indicators are either off, red, green, or yellow, depending on what is connected to the port. The indications are:off- nothing attached red- QSC DSP accessory attached green- QSC DataPort amplifier attached yellow- QSC DSP and Amplifier combination attached LCD Display and Controls The BASIS 922az has a 2 line X 16 character LCD display. The display and the multi-function push-button switches on either side provide data access and editing capability. The push-button switches on either side of the display are used to navigate through the menus. The rotary select/accept knob is active for many displayed items allowing you to scroll through choices by rotating the control, and accepting choices (entering) by pushing in on the control.
