- Page 4 DSP-30. The BASIS 922uz brings all that technology together in one compact, powerful, easy to use system. We are confident that your new BASIS 922uz will provide years of dependable service and we hope it will help you, the sys- tem designer and implementer, to express your creative audio system ideas.
- Page 5 The BASIS 922uz supports two distinct kinds of network activity; the first is audio transport via CobraNet, and the second is control and monitoring via QSControl.net. The user can choose to install one network for CobraNet traffic and a second separate network for QSControl.net traffic.
- Page 6 It should be noted here that while the CobraNet port on a BASIS 922uz is restricted to repeater LAN or switch LAN deployments, QSControl.net is a TCP/IP standards-compliant network system and therefore supports operation on network repeaters, switches and routers.
- Page 7 BASIS products all of the time without having to physically switch between them. You still get the great performance of TCP/IP over Ethernet. (And we believe QSC's advanced 4th generation networking software provides the best performance of any networked audio control system available today including Ethernet based systems from competitors.)
- Page 8 Example #3 - Single Wire Interface: Here all QSControl.net and CobraNet traffic shares the same single CAT-5 cable between the BASIS 922uz and an unmanaged Ethernet switch. The QSControl.net system manages traffic flow efficiently and reliably so that all audio and control data is delivered to its appropriate destination anywhere on the network.
- Page 9 BASIS 922uz control and monitoring (including the system controller) and a second dedicated network for CobraNet audio. As with the previous example, as many BASIS 922uz units may be connected as there are switch ports available. All BASIS units will be able to communicate with the computer. All will have CobraNet audio.
- Page 10 Example #5 - Two-Wire Interface (separate network hardware): Example #5 is conceptually similar to example #4. The difference here is that separate networks are created by providing each local area network (LAN) with its own network switch. Therefore, traffic segmentation is physical rather than logical. Example #5 also pro- vides an additional level of fault tolerance, although at the expense of additional network hardware.

Page 11: Rack Mounting
5-pin terminal block connector Mounting The BASIS 922uz can be used in or out of an equipment rack. Rack mounting is optional. Adhesive rubber feet are included for non-rack mount installations. Use them to prevent the unit from scratching or marring support surfaces. - Page 12 Computer Requirements & Software Installation Installing QSControl.net is easy. All you need to do is choose the folder where the program is to be stored (the default setting is accept- able for most applications). We recommend your system meet the following minimum requirements: 1- IBM PC compatible computer with a Pentium 4 processor.

Configuration Memories The BASIS 922uz has non-volatile storage locations that contain settings for the device as well as DSP signal flow. The storage loca- tions make it possible to set up the BASIS for different situations and quickly recall the setup with or without QSControl.net software... - Page 14 Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the BASIS 922uz. Plug the AC line connector into the AC outlet. The power supply will accept from 100 to 240 Volts AC, 47 to 440 Hertz, without any changes. If a differ- ent type of IEC power cord is required than supplied with your 922uz, contact QSC’s...

Page 16: Lcd Display And Controls
LCD Display and Controls The BASIS 922uz 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. - Page 17 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 infor- mation when first setting up a network system. Once user moves to a different screen, the last screen accessed becomes the new power up default.

2- Connect a CAT-5 crossover cable from the computer’s network interface card (NIC) to the BASIS QSControl jack (example 1, page 6). 3- Reconnect the power cord to the BASIS 922uz (turn it on). Using the BASIS LCD display and controls, navigate the menu to the IP Address and make a note of it. - Page 19 AC power is properly applied to the BASIS. 19- Click on the “+” sign of the BASIS 922uz in the inventory root, then the “+” sign of the Flashed Configs. Click on the config with the loudspeaker icon. A view of applicable device tabs will open. Click the DSP block and the current DSP configuration of the BASIS will be displayed.

If the BASIS 922uz operates in an unexpected way or is not responding to any communications after a new firmware file is uploaded to it, it is likely the file was corrupted during transfer. If this occurs, there is a “backup” program in the BASIS 922uz that will enable you to communicate with it. - Page 22 6) The Hyper Terminal main window will appear next, but blank. Type the letter “h” (for help) and then the “Enter” key. This will prompt the BASIS 922uz to post its menu text. The “h” key is the Help prompt for the BASIS 922uz. A text menu will appear. This is sent by the BASIS 922uz and will detail your options and instructions for changing the address information.
