LED Indicators (continued)

QSControl and CobraNet Network Status (Port) Indicators- There are 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. Their func- tions are described below. 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 RAVE 522ua receives data from the corresponding network.

TX (transmit)- This indicator illuminates whenever the RAVE 522ua transmits data onto the corresponding network.

LINK STATUS- The corresponding indicator illuminates when the RAVE 522ua is connected to an operating network.

SIGNAL indicators- These indicators will illuminate green for input signals -40dB to -10dB below full scale; yellow for sig- nals between -10dB to -2dB below full scale; red for -2dB to full scale (or clip).

LCD Display and Controls

The RAVE 522ua 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.

The accessible menus and sub menus may appear differently than the example shown. Software updates may occasionally improve the interface. The basic navigation flow for the RAVE 522ua menu system is shown on the following page.

Front Panel Password Lockout

The password lockout provides the ability to restrict access to all of the editable parameters available on the LCD front panel. This feature is enabled or disabled via QSControl.net software only (refer to the “General Tab” area and click on the “Front Panel Password” button). When the lockout feature is enabled, all front panel LCD functions are readable, but editing of parameters is now password protected. While in this mode, any attempt to edit a parameter will require the user to enter the Front Panel Password. The default factory password is “qsc”. The password is stored in the RAVE unit and can be changed using the QSControl.net software.

Once the password has been correctly entered, the RAVE will allow edits to the parameters.

After 5 minutes of inactivity, the RAVE will automatically reset the Front Panel Password lockout. Re-entry of the password will be required to resume editing.

The lockout mode can be deliberately disabled via the “Disable Edits” checkbox in the Front Panel Password menu of the QSControl.net software.
