8 HARDWARE INSTALLATION
This section explains how to install one or more AudioScience adapters in a computer.
Setting Adapter Index – One Adapter in the PC
8.1
1. Make sure your computer is turned off.
2. PCI adapters should be installed in any empty PCI slot and PCIe adapters should be installed in any x1 (or
greater) PCIe slot.
3. Make sure the adapter jumper is set to adapter index #1, the factory default. For a new card no changes need
to be made. For an AudioScience adapter from another installation, check that it is set to adapter index #1.
Depending on the adapter family, there are different ways of setting the adapter index.
For ASI5000 and ASI6000 families, there is
an adapter jumper that must be set. The left
most position represents adapter index #1.
Adapter Jumper set
to Adapter #1
For ASI5300, ASI6300, ASI8700, and
ASI8900 families, there is a rotary switch.
NOTE: Position 0 (zero) represents adapter
#1, position 1 is adapter #2, etc.
Adapter Index switch
set to Adapter #1
4. Turn on the computer and let it boot. Under Windows, a dialog box will pop up informing you that the computer
has detected a new Multimedia Audio card. Cancel out of this dialog box and proceed to the software installation
section of this datasheet.
8.1.1
Setting Adapter Index - Two or More Adapters in the PC
1. Make sure your computer is turned off.
2. PCI adapters should be installed in any empty PCI slots and PCIe adapters should be installed in any x1 (or
greater) PCIe slots. Different adapter types can coexist in the same computer; for example, an ASI6416 and
ASI8921 will work correctly if installed in the same PC. Different adapter types still require unique adapter index
numbers.
3. Each adapter in the PC needs to have its adapter jumper/rotary switch position set to unique numbers. For
example if you are installing two adapters, the first one would be set to adapter index #1 and the second to
adapter index #2.
3.1. For ASI5000 and ASI6000 families, the position to the right of index #1, when jumpered, represents adapter
index #2. The next position represents #3, and the rightmost position, when jumpered, represents #4.
3.2. For ASI5300, ASI6300, ASI8700, and ASI8900 families, rotate the rotary switch to indicate what position is
required.
4.
Turn on the computer and let it boot. Under Windows, a dialog box will pop up informing you that the
computer has detected a new Multimedia Audio card. Cancel out of this dialog box and proceed to the
software installation section of this datasheet.

9 SOFTWARE INSTALLATION
AudioScience makes audio adapters and drivers for various operating systems. Enhancements to an adapter’s
utility come from the integrators software that uses the audio driver to implement sophisticated audio playback
and recording functions.
9.1
Drivers for Windows 8, 7, Server 2008, Server 2012
Typically, drivers are not included with the hardware and will need to be downloaded from the AudioScience
website. They can be found here: http://www.audioscience.com/internet/download/win_drivers.htm
The first step is to determine what type of driver is needed for your operating system. Drivers are available for 32bit and 64-bit Windows systems.
Driver 3.10 and later present the user with three install options during installation:
 Install Standard PCI/PCIe Driver.
 Install Standard + Network Audio Driver.
 Remove all driver components
Traditional installs should select the first of these options. Users of AudioScience CobraNet and AVB products
should select the second option with the “+Network Audio Driver.” in the text.
9.1.1
Combo Driver
The Combo driver installs WDM devices by default and presents an option to “Install legacy 32-bit WAVE driver”
in case your application requires it. Download the file named ASICOMBO_xxxxxx.EXE from
www.audioscience.com and run it (_xxxxxx is the version number). After the EXE has run, reboot your computer
and the audio adapter will be operational. If the cover is off the computer, one can see one or two blinking LEDs
on top of the card indicating its DSP is running and communicating with the driver.
Verify that the adapter is running using ASIControl (see ASIControl section in this document).
9.1.2
ASIO
All AudioScience drivers also install an ASIO driver interface. It is installed by default.
9.1.3
Driver Failure
In the event that an adapter’s driver fails to load, check the OS’s event viewer as follows:
7: The system event log is accessed from \Start\Control Panel\System and Maintenance\Administrative
Tools\Event Viewer. The Windows Logs\System view should be selected.
If two or more adapters are installed in the same system, the first thing to check is that the adapters were
assigned unique adapter numbers. If issues persist, please email support@audioscience.com.
9.2
Drivers for Linux
The latest Linux driver can be downloaded from the AudioScience website – www.audioscience.com
9.3
Applications for Windows
AudioScience provides ASIControl for adapter set-up and configuration.
9.3.1
ASIControl
All Windows drivers install an AudioScience application called ASIControl that can be used to setup and verify
functionality of adapters. ASIControl provides a common interface for users across all driver types.
From the Windows Start menu, navigate to StartProgramsAudioScience and run the ASIControl program.

10 OPERATION USING ASICONTROL
Using ASIControl, the ASI5602 will look like so:
Adapter
List
Window

Controls
Window
Adapter
Topology
Window
11 USER INTERFACE
ASIControl consists of three main windows: the adapter list in the top portion of the window, the adapter topology
view on the left hand side, and the node control list on the right hand side.
11.1.1 Adapter List Window
The top portion of ASIControl shows a list of all the adapters that the application has found. By default, only bus
based (i.e. PCI and/or PCI Express) adapters will be shown. If the network portion of the driver is installed (by
selecting “Install Standard + Networked Audio Driver” after running the driver installer) and “Local PCI(e) +
Networked adapters” is selected from ASIControl’s OptionsConfigure adapter interface, then AudioScience and
other third party CobraNet devices will be shown.
Adapters are listed in order of adapter index. For bus-based adapters, this is determined by the adapter index
jumper on the card. For AudioScience CobraNet devices this is calculated from the unit’s MAC address. Third
party CobraNet devices are listed last as they have no AudioScience index.
11.1.2 Adapter Topology Window
The left hand side of ASIControl contains the topology view of the adapter. It is essentially a block diagram of the
device showing the available physical inputs and outputs on the right hand side of the black, vertical ‘bus’ line. On
the left hand side of the bus line, bus-based adapters show player and recorder streams, while CobraNet
adapters show their network connections.
Each of the inputs and outputs is referred to as a node and each Node contains one or more controls. The
topology shows each control as a small icon. A non-exhaustive list of nodes follows:

Hovering the mouse over a particular node will highlight it. Clicking on a node will bring up the controls resident
on that node in the right hand control list.
There is an adapter node in the top left corner of the topology window. Clicking on this will show adapter-specific
controls and properties on the right hand side. Not all adapters have all nodes.
11.1.3 Node Controls Window
The right hand side of ASIControl shows the controls associated with the selected node in the topology view. The
controls are arranged, from top to bottom, in order of audio signal flow, i.e. the audio signal can be viewed as
entering the node at the top control and leaving at the bottom control. Controls may be used to either manipulate
the audio as it passes through the node, or report back control status information.
For a comprehensive listing of controls and how to operate ASIControl, please see the ASIControl manual
available from www.audioscience.com and also installed by the driver. Not all adapters have all controls.
The section below lists some common and any specific controls, as seen in ASIControl, for this adapter.

ASI5601/5602
14 BALANCED ANALOG I/O
The ASI5602 has stereo-balanced analog inputs and outputs on a mini 50-pin female connector.
14.1 Analog I/O Level
The analog Level (or Trim) is software programmable independently for the input and output. It can be set from 10 to +20dBu in 1dB increments.
User
Analog levels are adjusted using the Trim/Level controls located on the LineIn and LineOut panels in the
ASIControl
Developer
Windows – Analog levels are controlled using mixerSetControlDetails() on a control of type signed and
with the name Level/Trim.
HPI – Analog levels controlled using the HPI_LevelSet() API.
15 AESEBU I/O
The ASI5602 has an AES/EBU digital audio input and output on a mini 26-pin female connector. The AES/EBU
I/O operates at 32, 44.1, 48, 64, 88.2 or 96.
15.1 Channel Status and User Data
The ASI Mixer does not setup the Channel Status and User Data in the AES/EBU output. This must be done by
the application using the following APIs:
Windows – Use Digital I/O controls – see the “AudioScience WavX Specification” (SPCWAVX.PDF)
HPI – Use HPI_AESEBU_Transmitter_SetChannelStatus() and
HPI_AESEBU_Transmitter_SetUserData() APIs
Your application can also read the Channel Status and User Data of the AES/EBU input using the following APIs:
Windows – Use Digital I/O controls – see the “AudioScience WavX Specification” (SPCWAVX.PDF)
HPI – Use HPI_AESEBU_Receiver_GetChannelStatus() and HPI_AESEBU_Receiver_GetUserData()
16 SAMPLE RATE CLOCK
The ASI5602 has two methods of generating the sample clock. The default method is to use the on board sample
rate generator. The other method is to use the clock derived from any of the AES/EBU inputs. Selection between
these two clocking options is automatic. In other words, if a valid AES/EBU data stream is connected to any of the
AES/EBU inputs, that input will effectively become the master clock source for the adapter. <end>
