™ DriveRack Network Functions NETWORK FUNCTIONS ®
SECTION 7 ™ Network Functions DriveRack The Network Function section of this manual will provide you with detailed information for establishing and maintaining a communication network between the 480, 481 , 482 and 480R DriveRacks™, and a PC, via the GUI interface by utilizing an RS-485 network standard protocol through a back bone system. Use this section to optimize communication performance between networked DriveRacks™.
™ DriveRack SECTION 7 Network Functions 7.1 Network Connections (Specs) Recommended Cable Specifications: Essentially, any product in the DriveRack™ system offers several different options of communicating in a network system. From the factory, all DriveRack™ products ship with a single 1foot DB-9 network cable. The following applications utilize the the following cable recommendations: PC GUI Interface - DB-9 female-to-female nul modem cable. 480R and 480P - DB-9 male-to-male cable.
SECTION 7 ™ Network Functions DriveRack 7.2 Network Connections (Applications) Backbone Connections The network system of the DriveRack™ has been configured to allow the units within a multiple unit network configuration communicate through a Back bone type connection. This allows the units to transmit and receive information immediately through the line instead of the conventional daisy chain system. The illustration below shows an example of the Back Bone network system.
™ DriveRack SECTION 7 Network Functions Connection to the 480R When the 480R Remote Controller is used in a network system, networking connection to the 480R Remote Controller must be accessed through the 480P power supply unit which included with the 480R. The following illustration shows the proper connections for 480R utilization. Note that when you are making network connections using the 480R, that you must first connect the 480R to the included 480P.
SECTION 7 ™ Network Functions DriveRack Connection to the GUI Interface: If you elect to utilize the included GUI PC interface, either the 480, 481 or 482 can act as the master unit that interfaces with the PC. Once the master unit has been established, access to all other units within the network system can be controlled via the PC. The following illustration shows how to establish connection from the PC to the Master controller to the slaves.
™ DriveRack SECTION 7 Network Functions Termination: In order to run your DriveRack™ system in the most effective and efficient manner, it is recommended that you utilize the included network terminator connectors. These terminator connectors essentially limit the networking information from the beginning to the ending of the Back bone network.
SECTION 7 ™ Network Functions DriveRack 7.3 Master/Slave Assignments The key element to establishing a DriveRack™ network system, is distinguishing a Master controller unit from the slaves units. Every unit in the DriveRack™ system has the ability to be assigned as a master or slave unit, but only one master must be assigned. A unit is designated as a master by setting the ID to 0 for the 481 or 482, or select Mst on a 480.
™ DriveRack SECTION 7 Network Functions 7.3 Master/Slave Assignments cont’d 480R DriveRack™ • Using the previous procedure for the master unit, you now need to enter the ID number for the master (0) on the keypad of the 480R and then hit enter. • At this point, you will need to access the Utility menu of the master controller.
SECTION 7 ™ Network Functions DriveRack • Use the PARAMETER 2 knob to set the Target ID. This simply means that you are asking the 480 DriveRack™ to call up the device ID of any one of the other DriveRack™ units that are in the network system. • Once you have called up the desired device, press the PARAMETER 3 knob to activate the device link. • Once the PARAMETER 3 knob is pressed, the unit will return to program mode.
™ DriveRack SECTION 7 Network Functions 7.4 Redundancy The Redundancy function of the 480, 481, and 482 DriveRack™ units is the very definition of the old saying that you can never be too safe. This unique function of the DriveRack™ units ensure that programming information in the 480, 481 and 482 DriveRack™ units is safe guarded in the event of any unfortunate malfunction.
SECTION 7 ™ Network Functions DriveRack 7.5 Network Trouble Shooting Since a DriveRack™ network system can be so very detailed with a tremendous amount of information being transmitted across the network backbone, the following information is provided to aid you in the unfortunate event that you have network communication problems in your DriveRack™ system.
™ DriveRack SECTION 7 Network Functions 7.6 PC GUI Installation To make operation of the DriveRack™ units even more convenient, dbx professional products includes the DriveRack™ PC GUI software with every unit shipped. The GUI interface will allow you to control all aspects of the DriveRack™ units. The GUI interface will also allow you to run your entire DriveRack™ network system from a PC. The GUI interface also makes it convenient for setting up systems prior to arriving at the venue.
SECTION 7 ™ Network Functions DriveRack Basic VENUE View • At this point, the DriveRack™ icons represent each unit that is currently setup to operate in the Network. To edit any unit in the network, select the desired unit with the mouse and double click. • To adjust the utility menu features of any unit in the network and Right-Click-hold to pull down the utility menu.
™ DriveRack Network Functions SECTION 7 • To customize the mode of operation to best suit your needs, it is recommended that at this point, you set your desired preferences in the preference folder, which can be accessed in the file menu and will appear as follows: Note: The Baud rate must be set to 38400.
SECTION 7 ™ Network Functions DriveRack Edit View • Notice that you can have as many windows open as required by your application. The intuitive interface of the DriveRack™ GUI allows you to make selections to any parameter of any unit all in real time. • When there are many windows open for several units in the DriveRack™ network, note that each window header indicates which network unit the module is used in. This will help spare any confusion as to which unit is being edited.

™ DriveRack Appendix A A.2 Factory Reset In the unfortunate event that a reset is required, the DriveRack™ units offer you the option of performing a “Soft” or “Hard” reset. The Soft Reset resets everything except user programs. The Hard Reset Procedure will reset all programmable information back to the factory defaults.
™ DriveRack Appendix A 482 Toggle RS-232/MIDI. Press and hold and at power-up until "232" appears in the 7-Seg Display. Watch as the fourth digit in the display toggles from "1" to "0" or from "0" to "1". If the final result is "1" the system is set up to communicate with RS-232. If the final result is "0" the system is set up to communicate with MIDI. Let go of the buttons and normal resetting will continue. A.

™ DriveRack Appendix A A.8 Gain Level Jumpers CAUTION: These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. Refer all servicing to qualified service personnel. Disconnect mains power before servicing. The 480, 481 and 482 DriveRack™ units offer you the option of changing the input gain level settings.

™ DriveRack Appendix A A.10 “Pinking” A Room To optimize sound performance in a live application, you may wish to “Pink” a room with the Real Time Analyzer available in the 480 and 480R DriveRack™ units. Pink Noise is defined as equal loudness at all frequencies. Pinking a room gives you a good starting point for fine-tuning the room to your desired requirements. The built-in pink noise generator (along with the built-in RTA), will help provide an accurate reading of the outputs of your speakers.
