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. [. . . ] TX (transmit)- This indicator illuminates whenever the DSP 322ua transmits data onto the network. LINK STATUS- The corresponding indicator illuminates when the DSP 322ua is connected to an operating network. SIGNAL indicators- These indicators will illuminate green for input signals -40dB to -10dB below full scale; yellow for signals between -10dB to -2dB below full scale; red for -2dB to full scale (or clip).
LCD Display and Controls
The DSP 322ua 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. The basic navigation flow for the DSP 322ua 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 requires the user to enter the Front Panel Password. The password is stored in the DSP unit and can be changed using the QSControl. net software. Once the password has been correctly entered, the DSP will allow edits to the parameters. After 5 minutes of inactivity, the DSP will automatically reset the Front Panel Password lockout. The lockout mode can be deliberately disabled via the "Disable Edits" checkbox in the Front Panel Password menu of the QSControl. net software.

LCD Navigation Map
Left side buttons have screen dependent functions. This read-only screen is the "out of the box" default display after power up. This is the most desired information when first setting up a network system. Once user moves to a different screen, the last screen accessed becomes the new power up default. Rotate to move cursor and push to accept change.
Right side buttons serve as up/down navigation. If additional menus are available, the arrow character will be shown.
*Note: After successful password entry, all screens with editable parameters will have read write capability. Without password entry, these screens will be read-only.

Getting Started
This section outlines one of the simpler methods of getting familiar with your DSP 322ua and the QSControl. net software. The goal of this procedure is to get your computer and the DSP 322ua connected and communicating and the QSControl. net software installed and running. [. . . ] 3- Now you have the same options that are available in the Serial Port I/O (RS-232) interface section. 17
