4 0.396 milliseconds. When analog input and analog outputs are used, the total delay is 2.354 milliseconds. The delay does not change regardless of the dsp configuration, unless the configuration intentionally adds more delay. The basis 922uz also supports the new optional low- latency cobranet feat...

5 introduction - networking the basis 922uz the basis 922uz has two rj-45 network connection ports on the rear panel. One port is labeled "qscontrol" and supports standard 10base-t ethernet. The other port is labeled "cobranet" and supports 100base-tx, also known as "fast ethernet". In the following...

6 third, the basis 922uz 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 addition, the sophistication and scalability of netwo...

7 example #2 - cobranet x-over mode: this is the simplest connection you can make between two basis boxes. Use a cat-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 cobra- net....

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...

9 example #4 - two-wire interface (shared network hardware): this example illustrates the two-wire interface with a managed ethernet switch. The switch is configured with multiple virtual local area networks (vlans). Ethernet deliveries can only reach destination ports belonging to the same vlan fro...
Page 10
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 ...

11 unpacking there are no special unpacking precautions. However, it is recommended you keep the original packing material for reuse in the rare event that service be required. If service is required and the original packing material is not available, ensure that the unit is adequately protected for...

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 compat...

13 general information & configuration memories amplifier setup the qsc dataport-equipped amplifiers connected to the basis 922uz must have their power switches in the “on” position. For initial testing, use the lowest useful gain setting until the system is operating as expected. After the system 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 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 ...

16 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 andlink. One group is for the qscontrol network port and the other for the cobranet network port. Their functions are described below....

20 operation qscontrol port the qscontrol port operates on a 10baset ethernet network. This port 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-negotiating) network interface card using a crossove...

22 utility/diagnostic functions (continued) rs-232 communications procedure: 1) connect the rs-232 port of the basis 922uz to an unused serial port (com port) of a pc using a normal (straight-through) serial cable. 2) open the hyperterminal program. This program is usually started by clicking the wi...
