4 0.396 milliseconds. From digital input to analog output, the total delay is 2.167 milliseconds. The delay does not change regardless of the DSP configur ation, unless the configura- tion intentionally adds more delay . The BASIS 922dz also supports the new optional low- latency CobraNet feature that provides transport at only 2.66 milliseconds de[...]

5 Introduction - Networ king the BASIS 922dz The BASIS 922dz has two RJ-45 network connection ports on the r ear panel. One port is labeled "QSControl" and supports standard 10BASE-T Ethernet. The other port is labeled "CobraNet" and supports 100BASE-TX, also k nown as "Fas t Ethernet". In the followi ng sections we de[...]

6 Third, the BASIS 922dz and QSControl.net system are targeted at network switch deployments. The consumer costs of Ethernet switches have continued to fall over the last several years and are now comparable with repeaters on a per port basis. In addit ion, the sophistication and scalability of network switches make them i deal for new installation[...]

7 Example #2 - CobraN et X-over mode: This is the simplest connection you can make between two BASI S boxes. Use a CA T -5 crossover cable connected between the Cobra- Net ports of each unit. No network switch is required. This connection allows audio to pass between the two BASIS boxes over Co bra- Net. Combining example 1 and 2 lets you setup and[...]

8 Example #3 - Singl e Wire Interface: Here all QSControl.net and CobraNet traffic shares the sa me single CA T -5 cable between the BASIS 922dz and an unmanaged Etherne t 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 netw[...]

9 Example #4 - T wo-Wire Interf ace (shared network hardware): This example illustrates the T wo-Wire Interface with a managed Et hernet switch. The switch is configured with multiple virtual local area networks (VLANs). Ethernet deliveries can only reach des tination ports belonging to the same VLAN from which it was sourced. The figure shows a se[...]

10 Example #5 - T wo-Wire Interf ace (separate netwo rk hardware): Example #5 is conceptually similar to example #4. The differenc e here is that separate networks are created by providing each l ocal area network (LAN) with its own network switch. Therefore, tra ffic segmentation is physical rather than logical. Ex ample #5 also pro- vides an addi[...]

11 Unpacking There are no special unpacking precautions. However , it is recomm ended you keep the original pa cking material for reuse in the rare event that service be required. If service is required and the or iginal packing material is not available, ensure that the unit is adequately protected for shipment (strong box of appropriate size, suf[...]

12 Computer Requirements & Software Installation Installing QSControl.net is easy . All you need to do is choose th e folder where the program is to be stored (the default settin g is accept- able for most applications). We recommend your syste m meet the following minimum requirements: 1- IBM PC compatible computer with a Pentium 4 processor .[...]

13 General Information & Configuration Memories Amplifier Setup The QSC DataPort-equipped amplifiers connected to the BASIS 922dz must have their power switches in the “on” position. For init ial testing, use the lowest useful gain setting until the system is operating as expected. After the system setup has been verified and tested, gain s[...]

14 Connections AC Power Cord Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the BASIS 922dz. Plug the AC line connector into the AC outlet. The power supply will accept from 100 to 240 V olts AC, 47 to 440 Hertz, without any changes. If a different type of IEC power cord is required than supplied with your [...]

15 Monitor Chain connectio n. See explanation, at le ft. In Out Monitor Chain The MONITOR CHAIN connector is a 5-pin terminal block connector . Input and output connec- tions are balanced. The center pin is the shield connection for both the input and output of the monitor chain. Connection is shown at right. The left-most + and - terminals are for[...]

16 LED Indicators (continued) QSControl and Cobra Net Network St atus (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 po rt and the other for the CobraNet network port. Their functions are described below . Note: Port indicators on rear panel are colo[...]

17 LCD Navigation Map Left side button s have screen depe ndent functio ns. This read- only screen is the “out of the box” default display after power up. This is the most desired infor- mation when first sett ing up a network system. Once user moves to a different scre en, the last screen accessed become s the new power up default. Boot Screen[...]

18 Getting Started This section outlines one of the simpler methods of getting familiar with your BASIS and the QSControl.net software. The goal o f this procedure is to get your computer and the BASIS connected and co mmunicating and the QSControl.net software installed and runnin g. After the software is installed and running, refer to the softwa[...]

Select the Device T ype and select BASIS 922dz. At the Password prompt, enter “qsc” (lower case, no quot ation marks). This is the device password, separate fro[...]

20 Operation QSControl Port The QSControl port operates on a 10BaseT Ethernet network. This por t is one of the primary means for connecting QSControl.net to the BASIS. The port may connect directly to a PC's 10BaseT or 10/100 (auto-sensing or auto-neg otiating) network interface card usin g a crossover cable. Data from the QSControl port may [...]

21 Utility/Diagnostic Functions Safe Mode Switch Location of Safe Mode switch: The front panel has a small access hole on the left side, just left of the Power indicator . It is not labeled to help prevent accidental use. The Safe Mode switch c an be operated by using a paper -clip (or similar item) inserted i nto the access hole and pushing. Safe [...]

22 Utility/Diagnostic Fu nctions (continued) RS-232 Communications Procedure: 1) Connect the RS-232 port of the BASIS 922dz to an unused serial po rt (COM port) of a PC using a normal (straight-through) serial cable. 2) Open the HyperT erminal program. This p rogram is usually star ted by clicking the Windows ST ART icon, highlighting PROGRAMS, the[...]

23 Utility/Diagnostic Fu nctions (continued) T elnet Access The RS-232 features can also be accessed via T elnet. The Micros oft T elnet application is a Windows program. Consult Windows documentation for T e lnet information. Basic procedure for opening a T elnet session: 1 - T o open the T elnet session- Click ST ART , select RUN, type “T elnet[...]
