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.

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 914lz 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 914lz is plugged into a properly functioning AC source. 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)

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. net 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 914lz receives data from the corresponding network. TX (transmit)- This indicator illuminates whenever the BASIS 914lz transmits data onto the corresponding network. LINK STATUS- The corresponding indicator illuminates when the BASIS 914lz 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 accessory and Amplifier combination attached
LCD Display and Controls
The BASIS 914lz 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.

Telnet Access
The RS-232 features can also be accessed via Telnet. Basic procedure for opening a Telnet session: 1- To open the Telnet session- Click START, select RUN, type "Telnet" followed by a space, then the IP address of the BASIS 914lz you want to communicate with in the text box and click OK. 2- If the address entered was correct and network communications with the BASIS 914lz are successful, the Telnet session should open. 3- Now you have the same options that are available in the Serial Port I/O (RS-232) interface section.
