This package includes a WDM DirectSound driver. Microsoft DirectX 9 or a later version must also be installed. The card can also be used with applications based on Digigram‘s np SDK Supported operating systems PCX924HR and PCX924HR-Mic cards run under Windows 2000, Windows XP1, and Windows 2003 Server1, are compatible np SDK, and come along with low-latency DirectSound, Wave, and ASIO drivers. HARDWARE INSTALLATION The card has to be installed in the computer prior to installing its driver. Installing the card Gently plug the card in a free PCI slot and press it down to position it firmly. Tighten the screw. Interrupt and memory address Hardware interrupt and addresses are automatically set up at start-up by the PCI PnP BIOS. SOFTWARE INSTALLATION Please visit the Digigram web site at www.digigram.com for the most recent driver. In case you run a specific application developed or installed by a Digigram partner, it might require the use of a specific driver version. In this case, make sure that the updated driver has been approved by your supplier. 3- bit version D Installation under Windows 2000, XP, and Windows Server 2003 If the driver has been downloaded from our web site, it has to be expanded prior to the driver’s installation as follows: double-click on the downloaded file (self-expanding). You can use the default destination location (Windows temporary folder) or select another directory. • Shut down your computer and insert your PCX card. • Restart your computer. • Click on Cancel if the “Found New Hardware” Wizard appears. • Double-click on the setup.exe icon to launch the driver installation. • A welcome message is displayed, click Next to continue. • The “License Agreement” window appears: read it, and click on Yes to approve it. Do the same for the “Read Me First” window. • Choose the destination folder where Setup will install the application files (..\pcxnp by default). Note that the driver files are installed in ..\windows\system32\Drivers\Digigram\PCXHR Next. • In the “Select components” window make sure that the “Driver for the HR boards” has been selected. • Select the program folder where the program icons will be added (default: DIGIGRAM). Next. • Click on Next to start copying the files. • Click on Continue anyway in the “Hardware installation” window (Windows XP). • In the “Digigram drivers” window, select the number and the size of buffers required by your applications. Click on Ok. • Click on the Finish button to complete the driver installation. Removing the driver under Windows 2000, XP, and Windows Server 2003 • • • • 10 Open the Windows Control Panel and double-click on the Add/Remove Software icon. Select "Digigram HR Runtime …", and Change/Remove. Select Remove in the “HR Runtime” window. Follow the instructions to finish the driver removal. PCX924HR & PCX924HR-Mic, PCX22HR User’s Manual How to check the installation Once the driver and the cards are installed according to the procedure described in this manual, you can verify that the card is properly installed and works fine as follows: • Menu, , tab “Audio”, Default device (Playback device, Recording device). The card’s channels can be selected. the card can be used with any DirectSound application (see pages hereafter). • The card is also visible via the np interface: Go to and select . • In the “Digigram drivers” window, select the ‘General Information’ tab. In the “Modules Information” window, you can see the HR Runtime modules that have been installed, and their versions. • In the “Digigram drivers” window, select the ‘Diagnostics’ tab. You should see here the icons of the cards you have installed. If the card you have installed is listed: • Right click on the icon of the card. • Select Diagnostics, and Play Sine. This plays in loop a sine signal on the outputs of the card. You can also select Play file to play in loop a file of your choice (PCM or MPEG). If the playback is correct, the card is correctly installed and works. • To stop the playback, right click on the card icon, and select Stop Activities. The card is also visible via the DHS control panel (cf. dedicated chapter next page). If the card is not displayed: • Make sure that during the HR runtime installation the “Driver for the HR boards” has been selected in the “Select components” window. • make sure that the card is correctly inserted in the PCI slot, and screwed on the PC chassis. • if necessary, uninstall HR runtime package as described in this manual, and re-install it. 11 D The ‘Digigram Hardware Settings’ (‘DHS’) control panel Digigram hardware settings (DHS) is an application allowing to configure the hardware resources of Digigram cards for all audio applications using them. A resource being managed by the DHS application can not be modified by any other applications. To enable an audio application to modify a Digigram card resource, this resource must not be managed by the DHS. Note: As soon as a resource of a card is managed by the DHS, the clock selection of this chart must obligatorily be defined in the DHS. The DHS allows to define: • Selection of the clock the card uses • selection of the input source • Analog and digital gain of an input • Enable Sample Rate Converters of an input: • Select the input monitored on an output • Set the monitoring gains • Set the analog and digital gains of an output • Define the digital output format For help on how to use this control panel, please refer to its on-line help. 12 PCX924HR & PCX924HR-Mic, PCX22HR User’s Manual SPECIFICATIONS Configuration Bus/Format Digital Signal Processor RAM Size Power requirements (+3.3V/+5V / +12V / – 12V) Operating: temp / humidity (non-condensing) Storage: temp / humidity (non-condensing) PCX924HR PCX924HR-Mic PCX22HR PCI 2.2, “Universal PCI 32-bit/66 MHz” master mode, “short-length” PCI format compatible, PCI-X compatible Motorola 56303 at 100 MHz 512 kWords 175 mm x 99 mm x 20 mm 0,35 A / 0,2 A / 0,2 A / 0,08 A 0,4 A / 0,3 A∗ / 0,22 A / 0,1 A 0,30 A / 0,18 A / 0,18 A / 0,08 A 0°C / +50°C • 5% / 90% -5°C / +70°C • 0% / 95% Inputs PCX924HR Analog line inputs (mono) Maximum input level/impedance Digital inputs (stereo) Other inputs Programmable input gain Other inputs AES11 synchronization PCX924HR-Mic PCX22HR ∗∗ 2 balanced +24 dBu / >10 k( 1 AES/EBU∗∗∗ with hardware sample rate coverter (SRC) AES/EBU Sync (up to 200 kHz) analog: from –94 dB to +16 dB ⊗ digital: from –110 dB to +18 dB 2 GPI (dry contact), LTC Yes ∗ enabling phantom power (48 V) may increase this value by 50% using the 10 V AES42 power to feed the microphone may increase this value by 150% ∗∗ can be used with unbalanced signals ∗∗∗ can be used as S/PDIF interface as well ⊗ maximum sensitivity: 0 dBFs for –16 dBu input 13 D Additional functionalities – PCX 924HR-Mic Microphone input Digital input (stereo) 1 professional mono with - high-quality preamplifier - switchable 48 V phantom power - analog expander/compressor/limiter This input is mixed with the two line inputs before A/D conversion.
