DSP 322ua 8x8 Signal Processor Hardware Manual *TD-000199-00* TD-000199-00 rev.
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.
Don’t want to read the entire manual? Just want to dig right in? Go to page 14.... Introduction The DSP 322ua provides signal processing needs for an integrated functioning system. In conjunction with QSControl.net software, the DSP 322ua enables the user to design, test and deploy professional audio reinforcement systems ranging in size from one to hundreds of channels. A standard Windows computer is the principle user-interface for controlling the overall DSP/QSControl.net system.
Introduction (continued) regardless of the DSP configuration, unless the configuration intentionally adds more delay. Both software and firmware can be easily updated over the network. In the future, QSC will be adding new capabilities to QSControl.net. Our latest code releases and access to upto-date information on QSControl.net are available at www.qscontrol.net. We invite you to visit us there.
Introduction - Networking the DSP 322ua Notes on Network System Design: As with any communications system, the reliability and performance of a local area network (LAN) is intimately related to the designer's skill and knowledge in implementing a topology that is robust, efficient and standards-compliant. Proper network design is even more critical in distributed multimedia systems.
Example #2 - Connection to an Unmanaged Switch: Switches can be connected to other switches to build larger networks; all of the normal networking principles apply. Here all QSControl.net traffic resides on a single unmanaged Ethernet switch. The DSP 322ua connects directly to the switch. A computer hosting a QSControl.net server application also connects directly to the switch. All configuration and monitoring of the DSP 322ua is performed via the PC.
Example #3 - Connection to a Managed Switch: This example illustrates a connection 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 from which it was sourced. The figure shows a separate VLAN for QSControl.net traffic and a separate VLAN for CobraNet audio traffic. This configuration essentially provides a dedicated network for QSControl.
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 shipment (strong box of appropriate size, sufficient packing material to prevent load-shifting or impact damage) or call QSC’s Technical Services Department for packing material and a carton.
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 acceptable for most applications). We recommend your system meet the following minimum requirements: 1- IBM PC compatible computer with a Pentium 4 processor. 2- Processor speed of 1 GHz (2 GHz or faster recommended for systems with 30 or more BASIS/RAVE/DSP units).
Connections AC Power Cord Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the DSP 322ua. 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 different type of IEC power cord is required than the one supplied with your 522aa, contact QSC’s Technical Services Department. QSControl Connect one end of a category-5 cable terminated with an RJ45 plug into the QSControl receptacle.
Relay Out Two sets of relay contacts are provided, RELAY OUT 1 and RELAY OUT 2. Contacts are floating and rated for 30VDC, 1A. There is one common terminal, one normally-closed contact terminal and one normally-open contact terminal. These are labeled as C, NC and NO on the rear panel. When the relay is not energized, the C terminal is connected to the NC terminal and the NO terminal is not connected; when the relay is energized the C to NC connection is opened and the C to NO connection is closed.
LED Indicators (continued) QSControl Status (Port) Indicators- There are three LEDs on the front and rear panels labeled RX, TX and LINK. These indicate the status for the QSControl.net network. Their functions are described below. RX (receive)- This indicator illuminates any time the DSP 322ua receives data from the network. TX (transmit)- This indicator illuminates whenever the DSP 322ua transmits data onto the network.
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. Use rotary data wheel to edit data. Rotate to move cursor and push to accept change. Boot Screen Right side buttons serve as up/down navigation.
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. After the software is installed and running, refer to the software’s Help file for all software related operation/issues. Note! The default password for the DSP 322ua is “qsc” (no quotes, lower case).
Getting Started (continued) 17- Select Device, Add Device, from the menu. A new window will open prompting you to name the device. Name it logically, such as DSP 1, or similar. Select the Device Type and select DSP 322ua. At the Password prompt, enter “qsc” (lower case, no quotation marks). This is the device password, separate from the software password. The default, in both cases, is “qsc”, but you are free to change either or both. Enter the IP address of the DSP 322ua and click OK.
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 DSP 322ua. The port may connect directly to a PC's 10BaseT or 10/100 (auto-sensing or auto-negotiating) network interface card using a crossover cable. Data from the QSControl port may also pass through network repeaters, network switches and routers.
Utility/Diagnostic Functions (continued) RS-232 Communications Procedure: 1) Connect the RS-232 port of the DSP 322ua 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 Windows Start icon, selecting Programs, then Accessories, Communications, and finally, highlighting the Hyper Terminal folder and clicking on its icon.
