Presentation : Installation & Setup : NBSPortDriver failed
Jens Bölte	Hello, I tried to install the Presentation version 11.04.05.07 on a Windows 2000 System. The following error message appeared during the installation procedure: Installation of NBSPortDriver failed Call to devcon install returned rval = 2 ... remaining text deleted What does this mean and how do I install this driver? Jens Bölte
Mark Hechim 2007-04-13 15:03 UTC	I am able to replicate this problem and hope to have a solution for you soon. Thank you for reporting this. Incidentally, we reccomend Windows XP over Windows 2000.
Margit Hoefler	Hello, Im afraid I have a similar problem: I tried to install a test version of presentation (we are going to find an alternative for our present tool) on our Subject PC (no internet connection) and the following error message appeared: Installation of NBSPortDriver failed. You might not be able to use the parallel port features in Presentation. Call to devcon install returned: rval=2 Device node created. Install is complete when drivers are installed.. Updating drivers for NBSPortsNBSPortDriver from D:Program FilesNeurobehavioral SystemsPresentationVersion110040507NBSPortDriver.inf. devcon. Installation was completed, nevertheless, but I wasnt able to start presentation until now (of course, I rebooted the computer). What can I do? Thank you for any advices! Margit
Peter Pebler 2007-04-23 11:50 UTC	Are you using Windows 2000?
Margit Hoefler	yes, we use Windows 2000 Margit
Peter Pebler 2007-04-24 12:58 UTC	We are going to release a fix for this tomorrow. If you don't need the latest version, you can download an older version from the Presentation download page.
Margit Hoefler	thank you! Margit
Anonymous 2007-05-10 04:50 UTC	Hello Peter Pebler, I also had problems with that driver. The solution is: Upgrade to the current version. But I downloaded the most recent Presentation version. I suspect that you mean the latest version of something else? Where can I find that? I'm posting anonymous because my username is somewhat awkward because I had to made up one very fast!

Anonymous	Hi, I just checked, but I think you actually mean that I have to dowload the latest version of presentation. But it still doesn't work here.. Maybe is just best to download an older version? Which one? Thank you in advance! Bernard Stienen
Anonymous 2007-05-10 05:24 UTC	Sorry about the message bomb, but when I try to install a later version I get this warning after setup and rebooting the system: 'The file 'NBSPortDriver.sys' on Presentation Installer Directory is needed. Type the path where the file is located and then click OK.' I am confused.. Bernard
Mark Hechim	Are you running as an administrator on your machine? Are you installing to the default 'C:Program FilesNeurobehavioral SystemsPresentationVersion110042507' directory? What happens if when that dialog box comes up you point it to that directory? If you use windows explorer to browse to that folder, is NBSPortDriver.sys in there?
Mark Hechim 2007-05-10 10:42 UTC	Also, are you using Windows 2000?
Anonymous	I just tried to install the latest version again, but things remain the same. It warns me that installation of the driver failed. I made a mistake in the post the last time (May 10, 2007 5:24 am) that the programm asked me to press ok, that was when I tried to install an older version. When I try to install the latest version, it says that the installation of the driver failed. Sorry I was confusing on that point. To answer your questions: Yes, I use windows 2000. I have sufficient rights (I think), I used the default directory and there is no NBSPortDriver.sys file (so it just ignores me when I press ok). I hope you can find a solution! Thank you in advance! Best regards, Bernard Stienen.
Margit Hoefler 2007-05-15 04:47 UTC	As I had written below, I had also had an installation problem. I finally found a new solution to solve it: I installed DirectX 9 instead of DirectX 8 and now presentation runs perfectly. (I didn't do anything else. I don't even know what exactly the problem was) Margit
Mark Hechim	Bernard, I am uncertain as to how NBSPortDriver.sys is not being put in your installation folder. Can you please download the latest version of Presentation from our website again (to ensure that you have the whole thing), and try installing it again? Afterward, please browse to C:Program FilesNeurobehavioral SystemsPresentationVersion110042507 where it should have installed Presentation and reply to this post with a list of all the files in that folder with names starting with 'NBS'. You should see: NbsBrowse.ocx NBSInstaller.exe NBSPortDriver.cat NBSPortDriver.inf NBSPortDriver.sys Also, you should see devcon.exe. Please tell us if any of those files are missing from your install folder.
Dr. Bernhard Müller 2007-05-15 12:24 UTC	Dear Mark, none of those files is missing following a new download and installation of Presentation 11.04.25.07 (and they have been there before). The device manager has an entry 'NBS Port Interfaces' and there is an 'unknown device'. When I open it the device status tells me that the drivers have not been installed (code 28).
Mark Hechim	Ok, let's try a few things to troubleshoot this. 1) Disable Driver Signing requirements 2) Delete the old driver 3) Reinstall Here's how: 1) Open Control Panel. Run System. Go to the Hardware tab. Click the 'Driver Signing..' button. Select 'Ignore'. Click OK twice. 2) Browse to C:WINNTsystem32drivers. Delete NBSPortDriver.sys. Open Control Panel. Run System. Go to the Hardware tab. Click the 'Device Manager..' button. Expand the 'NBS Port Interfaces' item. Right click any item beneath that and click 'Uninstall..'. Click OK. If you are asked 'Do you want to restart your computer now?' click 'No'. Do this for each device under 'NBS Port Devices' until all are gone. Click the 'View' menu item. Click 'Show hidden devices' sub-menu item. You should now see 'Non-Plug and Play Drivers' in the list of driver types. Expand it. Uinstall any of the following you may find there. 'NBS Win2k-XP PP Driver', 'NBS Win2k-XP PP Driver V2', 'nbsport', 'NBSPortDriver'. Reboot. 3) Browse to the C:Program FilesNeurobehavioral SystemsPresentationVersion110042507 folder. Run NBSInstaller.exe. Let me know how this goes and if you see any unusual/error messages.
Mark Hechim 2007-05-15 13:45 UTC	Sorry, we had a fix for Windows 2000 for this driver, but it accidentally got reverted back to old code and then released. We will post a new version of Presentation shortly with the fix added back in. If you want to get up and running now, you can open NBSPortDriver.inf and delete the following two lines.. CatalogFile=NBSPortDriver.cat Security = 'D:P(A;;GRGWGX;;;WD)(A;;GA;;;SY)(A;;GA;;;PU)(A;;GASDFAKACR;;;BA)(A;;GASDFAKACR;;;SO)' Save it. Then run NBSInstaller.exe. You should do this after uninstalling the old drivers as outlined in my previous message. Sorry for the inconvenience.
Anonymous	Hi Mark, I did exactly what you told me to do, and I don't get the warning anymore. The problem now is that when I connect the LPT port (I only got one) to a device to check whether signal is sent to the port I find nothing. This could be a problem with the custom build checker, but it could also be a driver problem (or a totall defect of my card of course). We keep on testing, but just to be sure: when I send '1' to the lpt port with the use of the port_code command in a scenario file, the signal is expected on pin 2, right? Thank you for your time and help! Bernard.
Mark Hechim 2007-05-16 10:33 UTC	Try sending 0, call wait_interval(20), then send 255, then wait_interval(20), then send 0 again.
Kristin Geraci	Please try using the Port output test feature rather than creating a scenario file to test the port output. The test feature is in the 'Output Ports' area of the 'Port' panel of the 'Settings' tab. You could try using the code 255 to see if any of pins 2-9 is being raised (though you are correct that a code of 1 should raise pin 2).
Jens Bölte 2007-06-12 09:14 UTC	Hi, when will the 'updated' WinXP-version be available? I downloaded the current version today (June, 12th) and failed to install it on a WinXP-computer. The error message was 'Process timed out in call to: devcon.exe devcon.exe dp_enum'. I followed the instruction given by Mark Hechim on May 15, 2007 1:10 pm. However, I get the same error message. Jens Bölte
Peter Pebler	The problems discussed in this thread were specific to Windows 2000. There was never a known problem with the driver installation on Windows XP. We will need to investigate this new problem further.
Mark Hechim 2007-06-12 15:55 UTC	That error, unless accompanied by other errors, should have no affect on whether the driver was installed. If you are able to use port functions without getting errors, then the driver is installed. We should now concentrate on making sure your port is working properly. Can you run the port tests that Krsiti mentioned in her last post?

The NBS Reference Monitor LoudSpeaker Systems are an original design by Walter Fields, the designer of NBS Audio Cables.
Our currently available LoudSpeaker Systems are:

PYRAMID SIREN AND THE ONE SIREN AND THE SARCOPHAGUS
WHITE PAPER: THE NBS PYRAMID LOUDSPEAKER SYSTEM
BACKGROUND
NBS Cables has been in the serious high-end audio business for over 16 years. In that time Walter Fields, its owner and principal designer has led the way in high-performance cables even before the general recognition that they were an essential part of any really high performance system. Early on NBS produced a novel loudspeaker system based on the premise of indirect radiation of the sound into the room. That has remained the hallmark of all NBS speaker systems.
NBS has also presented a very high-end power amplifier (at CES2000) which was widely praised but could not be moved into production because of supply problems from the Russian manufacturer who was the sole source for the output tubes. NBS also currently produces a series of high performance AC power conditioners for audio and instrumentation systems.
The loudspeakers to be discussed are an evolution of design concepts originally explored in the NBS Siren and NBS Sarcophagus systems.
PURPOSE
We make loudspeakers to enjoy music. The technical means to accomplish this are beside the point if they fail to connect the listener to the essential heart of the music. All the NBS loudspeakers are somewhat unorthodox in configuration because the simple truth is that 'blow-it-out-the front' rectangular box speakers generally don't deliver the goods. To serve the PURPOSE of connecting to the MUSIC, the NBS loudspeakers are necessarily different from the average speaker.
DESIGN APPROACH
The design begins by identifying the critical aspects of loudspeaker performance.
These are:

Wide frequency response

Low distortion

High 'speed' (transient response)

Big dynamic range

Convincing spatial presentation (imaging)

In addition, the system should look good, be very reliable and be built to last.

Wide frequency response and low distortion are fairly straightforward to achieve in a 3-way speaker system. The issues of apparent 'speed', dynamic range and imaging are equally serious and much more difficult to conquer.
The attribute of a speaker commonly called 'speed' is revealed when reproducing percussion, piano and other 'quick' sounds. It can only be accomplished by driver systems capable of high acceleration of the diaphragm(s). This, in turn, requires that the speakers' motors are capable of very high force in comparison to the mass they are required to move. Remember from high-school physics that acceleration = force/mass.
The accurate reproduction of dynamic range, i.e. the contrast between loud and soft, is absolutely crucial to the impression of realism. Unlike errors in frequency response or small amounts of distortion, which can occur naturally, compression of dynamic contrasts is purely a technical artifact and has no counterpart in nature. Hence, dynamic compression seriously compromises the sense of reality. Dynamic compression is very difficult to overcome, ordinarily requiring heroic driver design and/or the application of acoustic techniques such as horn-loading.
Spatial presentation, or imaging, is the ability of the stereo loudspeakers to convince us that the apparent origin of the sounds we are hearing is not in the speakers. Rather, we should perceive a 'space' within which the music occurs in both width and depth which is not tied to the visual location of the speakers.

Having identified and described these critical items, we must conceptualize a design which will address them.

Frequency range, distortion, 'speed' and freedom from compression are addressed mainly by the overall system arrangement and by the choice of the individual drivers. All NBS loudspeakers are 3-way designs. This insures that each driver is operated only in an appropriate frequency range. By doing this the full rating of the individual drivers can be exploited. The individual drivers are not designed by NBS but are procured in the OEM market. The selection of these drivers is critical to the success of the design and will be discussed later.
Spatial presentation is affected by the drivers, but it is their arrangement which determines the properties of the completed design. Indirect radiation has always been a hallmark of NBS loudspeakers and of many great designs over the decades. Other designers who have advocated this approach are G.A. Briggs (Wharfedale in its golden years), Stuart Hegeman (Eico and Harman Kardon in the 50s and 60s), Victor Brociner (Brociner Labs), Col. Ranger (JBL Ranger Paragon, Metregon and Minigon) and of course, Amar Bose.

SOLUTION
The configuration of the Pyramid is unusual in that when viewed from the front, no openings or speakers are apparent. The woofer faces the floor, the midrange apertures are on the sides and the tweeter is in back. All the sound reaches the listener by indirect paths. Because of this, the room reflections are properly excited by the speakers and are, in fact, required to produce the proper imaging.
The important aspect of this philosophy is that no reasonable room needs to be tampered with in order to achieve good results. Many speakers have such colored off-axis response that it is necessary to 'kill' the room reflections through acoustic treatment. This treats the symptom, not the disease. The problem is with the speaker, not the room. If the room has been 'killed' it will be necessary to 'un-kill' it for an indirect radiating speaker such as the Pyramid. When this is done, the result will be superior imaging over a very wide area. So now you can live in the room and have music too.
TECHNICAL MEANS
As mentioned above, the driver selection is critical. In all the NBS loudspeaker models, all the drivers are manufactured by the Professional Products Division of JBL. In the Pyramid, the three transducers are possibly the best of their respective kinds in the world. It follows that they are not inexpensive. The driver cost alone in the Pyramids exceeds the entire cost of goods for many $20,000+ speaker systems.
The woofer is a JBL 2235H, 15' unit in a sealed enclosure. Sealed systems invariably have better bass articulation than vented, or bass-reflex systems. By placing the driver close to the floor, the reflection dip which impairs the mid-bass performance of many systems is completely avoided. In our experience this is the most musically satisfying woofer we have ever heard. Because it is used near the reflecting plane of the floor, it has a practical sensitivity of 96 dB/Watt, which sets the sensitivity for the whole system.
The midrange is a JBL 2490H compression driver loaded in a 25' horn structure with conic expansion in a ratio of 2:1. This stupendous driver applied in this way has a raw sensitivity of over 105 dB SPL/Watt.
The tweeter is a JBL 2402H ring radiator. This is the modern version of one of the most classic horn tweeter designs. The horn is circular and there is no explicit diaphragm. The throat of the horn is driven by the edge of the voice coil. The response is very extended and the sensitivity is 110 dB SPL/W.
All these drivers have extraordinarily powerful motors. In the midrange and tweeter, exotic materials and designs give the lowest possible moving mass, hence very high acceleration (as discussed earlier).
The crossover uses the simplest topology that will do the job. The components are of the highest quality and comprise litz-wound air-core inductors and film-dielectric capacitors.
The cabinet shape of the pyramid ensures that diffractions around the cabinet are smoothly distributed in frequency. In all models the construction is of 1' thick material throughout and extensively braced (these are powerful systems).
