www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Chapter 2: System Description This chapter describes the different Digital Audio Communication System (DACS) hardware components and typical system configurations.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com The TDM Controller performs all the functions of the Waveform Synthesizer, but instead of analog inputs and outputs, it sends and receives sound in digital form across a TDM ring to one or more Remote Interface Units (RIUs). The RIUs handle all the D/A and A/D conversions, some local mixing, as well as a few digital inputs and outputs primarily for PTT (Press-To-Talk) and PTR (Press-To-Radio) sense/activation.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Figure 1: Typical Digital Audio Communication System Host Computer Instructor Environmental Sounds RIU RIU Host Commands Ethernet Pilot DACS Simulator Cockpit Amplifier Keyboard VGA Monitor DACS hardware and software components are described in more detail in the following sections. DACS Platform Descriptions ASTi offers several available chassis options for the DACS processing nodes.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com DACS Hardware Components The 2U and 4U DACS processing nodes consist of a number of hardware components, and can be configured in many different ways depending on the requirements of the particular application.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Memory installed varies from system to system depending on the requirements. Larger amounts of memory provide more cache area for sound recording and playback as well as additional sound model memory. Each system has a CPU reset button for hard reboot of the model processor. The reset button is located on the front of the chassis.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Waveform Synthesizers Waveform Synthesizers perform sound model digital signal processing and provide analog input and output interface for external equipment such as speakers, headsets, and microphones. Each individual Waveform Synthesizer contains a single DSP and performs all the signal processing associated with a specific, user developed, sound model.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Instead of providing analog interfaces local to the card, however, the TDM Controller forms a base driver for a Time Division Multiplex ring. This ring carries digital audio to and from Remote Interface Units populating the ring. The RIUs in turn provide the analog to digital interface at remote sites along the ring. See the next section for more information on the RIU.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Interconnection: As with the Waveform Synthesizer, a high speed communication port connection is provided. This port provides the capability to link up to three TDM Controller cards together to form large communications networks. Audio Processor Configuration In general, any combination of Waveform Synthesizers and TDM Controllers can be installed in a 2U or 4U DACS.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) All RIUs ship with a basic user guide which provides specifications, configuration information and other general information specific to the version of RIU shipped. Current and legacy RIU manuals may also be downloaded from the ASTi website: http://www.asti-usa.com/ Audio Inputs: Audio input preamp gain can be configured from 0dB to 60dB via jumpers on the RIU circuit card. Factory setting is a gain of 40dB.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com See Appendix A or consult your RIU documentation for additional specifications, configuration and interface information. Status Lights: For proper RIU operation, the RIUs must be synchronized with the TDM Controller. In a standard TDM ring configuration, the TDM controller continuously sends out a sync signal to all RIUs on the link. The RIUs synchronize to this signal at start-up.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) systems and spare cards also need to be properly keyed by ASTi. See the network card Remove and Replace procedures in chapter 5 for more information. Network interface cards are PCI based 10/100MBs ethernet cards supporting 100baseT (Unshielded Twisted Pair) connection. Ethernet operation conforms to IEEE 802.3. UDP level protocol with IP addressing is supported along with some multicast capabilities.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Tactical Data Link Interface Systems with Model Builder version 3.12 and higher have the ability to receive tactical data link information from another network computer for transmission over DIS or HLA networks in the form of Signal PDUs. Tactical data link information received by the DACS from the DIS or HLA network can also be returned to a network computer.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Models consist of different lists of high level sound, mixing, and control objects. Model Object Lists are comparable to an object database. Each object performs a specific function, e.g. generating a sine wave, simulating a radio, generating a noise source, connecting a host input control to an object parameter, or playing a prerecorded sound.

www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) The options file is keyed to the system ethernet card (Host Interface on systems with two cards), so that an options file on one system will not work on any other system. If it becomes necessary to replace the ethernet card, a new options file keyed for that specific ethernet card must also be installed. Ethernet spares shipped from ASTi include a new software key disk.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Software Licensing ASTi’s Model Builder software and optional packages are licensed on a per system basis. It is illegal to transfer this software to another platform or update to a later version of the software without expressed consent by ASTi. Software may be pre-installed on spare systems for support purposes. The software may not be operational, however, unless the spare system has replaced another down unit.

ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Monitor Connection For convenience, some 2U and/or 4U power supplies provide a power connection for the monitor on the rear of the chassis. This connection allows the monitor to be plugged directly into your DACS. Power cords to fit this connection can be purchased for your monitor from your local computer store or distributor. The monitor may also be connected to an independent power strip.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Control Panel and External Serial Device Connection: For those applications which require connection of a Hand Held Terminal, an operator control panel, simulated radio panel, or other serial device, no special hardware configuration is required. Note that serial port connection is only available for legacy RIU versions D and up, and the DACS must be running Model Builder version 4.0 or later.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Initialization: When the DACS powers up or when the Model Builder application software is booted, the RIUs will spend a few seconds synchronizing to the TDM card. The synchronization status is indicated by the green and red LEDs on the RIU. If the red LED is solid, there are no sync pulses on the TDM ring.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Line Level Device Connection: For most standard line level devices such as a tape player or VCR, the audio output of these devices can be connected directly to the Waveform Synthesizer input. Check the specs of the equipment, for the maximum output level of the equipment.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Audio Outputs Waveform Synthesizer audio outputs are low impedance (<100!), single ended (unbalanced) outputs. Maximum analog output levels are approximately 6Vp-p into 600! or larger loads. RIU audio outputs are low impedance (0.1! into an 8! load), differential (balanced) outputs. Each channel is capable of supplying 1W RMS into a bridge-connected 8! load.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Network Interface Connection Each DACS may contain one or two network interface cards. Network interface cards are PCI based 10/100Mbs Ethernet cards. Cable connection is located on the rear of the DACS chassis. Attach your Ethernet network cable(s) to the RJ45 connector(s). Standard off-the-shelf network cabling can be used to make the connection. Be sure to use cabling recommended for 100Mbs (Fast) ethernet applications.

ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Model Generation and Operation Overview The following sections provide a general operational overview of the DACS. Overview Of Hardware and Software Functions The Model Builder software is both a development platform for developing models and what actually runs the model. A model can be run as it is being entered, and changes can be seen (or heard!) immediately. It is not necessary to compile models.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Objects Models are made by entering the Model Builder software. This happens at start-up. Alternatively, from DOS, you can type MB. After a few seconds, the Main Menu will appear. (Menus may vary due to software configuration.) Move the Cursor to Models and press ENTER. The “Models” menu will appear: One model will appear for each DSP.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Moving the cursor to one of the model entries and pressing ENTER will produce the Model Configuration window. Pressing F2 will produce the following menu, which allows you to put objects into your model. A model consists of “objects” which are tied together. Objects are divided into three major types: Controls, Signals, and Feeders.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com The signal object would be tied to a Feeder object, “Buffer”, which would direct the sound to one of the analog outputs. The sound would then be played on the specified analog output (or outputs). Control In_Int Signal Play Sound Feeder Buffer D/A Conversion, audio output To add an object to the model, go to either Signal, Controls, or Feeders from the menu shown above.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Processor Loading There are two types of processors in an ASTi DACS - the model processor, which has a Pentium or other X86 microprocessor, and the DSP processors. There is one DSP processor on each DSP card. Both the Model Processor (or CPU) and the DSP processors can only handle a certain amount of information before they can no longer keep up with the simulation. Different tasks load these processors in varying amounts.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Network Interface Host Simulation Interface In order to manipulate or drive the sound and communications models developed on the DACS, a host simulation computer will normally provide simulation state and sound model control parameters such as engine RPM, radio frequency, radio position, communications panel switch settings, etc.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) During DIS operation, the DACS transmits and receives DIS standard PDUs. Since the DACS is involved strictly with communications simulation it transmits and receives Transmitter, Signal and Receiver PDUs only. In addition, to accommodate entity attach features whereby a radio modeled on the DACS is attached to an entity on the network, Entity State PDUs are also received.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Chapter 5: Test and Maintenance MTBF and MTTR Mean Time Between Failure numbers for all DACS modules are included in Appendix B. When spares support is at the recommended module level, DACS Mean Time To Repair is less than 45 minutes for 2U and 4U chassis. ** WARNING ** Removing the cover of the chassis, as is required for hardware replacement procedures described in this section, will void any warranties on the system.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Spares Recommendations To ensure the absolute minimum down time in the event of a failure, a “hot” spare unit is recommended. This spares the DACS at the system level and eliminates any need for technicians to enter the system to replace individual components. Hot spare units consist of the same components contained in the system(s) they are sparing.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com Preventative Maintenance Very little preventative maintenance is required for the DACS. The following sections provide preventative maintenance information. Filter Cleaning Once each month (or more often if dust build up occurs) inspect the fan filters for excessive dust and dirt. Filters should be kept clean to help prevent heat buildup within the DACS. • To clean the filters: • Power down the DACS. • Remove all fan covers.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Troubleshooting The following sections provide troubleshooting guide lines in the event of a problem with the DACS. Self Test Features Daily Readiness Test (DRED) for Audio I/O: Your Digital Audio System is supplied with three automated Daily Readiness (DRED) test routines, Local, Host and RIU.
ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) www.asti-usa.com During both Local and Host DRED tests, each Waveform Synthesizer output generates a different type of sound. Table 1 describes the type of sound heard on each Waveform Synthesizer output channel. If the Waveform Synthesizer has only two output channels, the first two sounds listed in the table will be generated.
www.asti-usa.com ASTi DACS: Operation & Maintenance Manual (Version 4, Rev. B.1) Before running the Host DRED test you will also need to have amplifiers and headsets or speakers connected to your Waveform Synthesizers in order to hear the test sounds. You will also need to connect your Host Ethernet link to the DACS. Table 3 below lists the packet byte location, data format, and data values that must be sent from the Host for proper test sound generation.
