Sb 16 pci full duplex HELP!

ok im running windows 98 with a soundblaster 6 pci and i cannot get full duplex why?i used to be running windows xp and i got full duplex fine could play 2 devices at once but with windows 98 i cant and i was wondering why i cant i play counterstrike and use ventrilo to chat at same time well when i start up the game it cuts ventrilo out so i cant talk and when im in the game i cant talk as well it cuts the sound off to ventrilo so that tthe game lets me hear but i cant hear the chat program so i get no full duplex on windows 98 please help how do i fix this

On those cards you had a choice of either full duplex (used by default in XP) or another setting reached by right click properties of the card in Device Manager. I forget exactly but I think it's the Direct Sound support?that needs to be turned off within that properties panel to enable full duplex. It's an either or situation on these cards. If direct sound is on, the full duplex mode is deactivated. I think Direct Sound games would still work, just without the hardware buffer support. I guess you could just toggle that back on when gaming and off when conferencing. You probably need to restart the computer for the changes to take effect.

Is PCI-6025E full duplexing ?

Do E series DAQ boards work in full-duplex mode ? Especially PCI-6025E .

I believe I may have sent you an e-mail about this. However, I would be glad to post about it here as well.
Full-duplexing is not a term we commonly associate with our DAQ boards. It is usually used in reference to serial-type communication that can go both ways at the same time (such as a modem). The best answer I can give on this is that the 6025E you asked about has 3 additional DIO ports (PA, PB, PC) which can operate in Bi-Directional Mode. This allows them to function as both inputs and outputs. The 6025E User's Manual is the best place to find more information about this.

Ettus USRP B200 full duplex at 16 or 32 MSPS?

I am testing the B200 with two different PCs, both running Ubuntu 14.04 LTS.
One is a 4 year old Core i7 PC with an Intel MB and a NEC Corporation uPD720200 USB 3.0 controller.
The other is a 1 year old Asus G750 laptop with an Intel 8 Series/C220 USB 3.0 controller.
Both machines can handle sustained (a few hours) 350+ MB/second transfers from a Point Grey USB 3.0 camera over a 3 meter cable with zero USB 3.0 errors reported by Point Grey's software. Note this is one direction of data flow over USB 3.0, not full duplex. The PC reached 356 MB/second. The laptop reached 369 MB/second. Both error free over periods of about 1 hour.
The B200 can reliably TX and RX (full duplex) at a common data rate of 4 MSPS on both machines.
8 MSPS full duplex is intermittently OK (occasional buffer overruns on both machines). Note: (8 MSPS) * (2 bytes/sample) * 2 (RX + TX) * 2 (I + Q) = 64 MB/second... fairly low for what USB 3.0 is capable of.
16 and 32 MSPS full duplex is never reliable (all runs result in buffer overruns and missing RX or TX data).
Command I'm using (set for 8 MSPS):
nice -20 ./txrx_loopback_to_file --file samples.dat --type float
--nsamps 50000000 --tx-rate 8000000 --rx-rate 8000000 --tx-freq
915000000.000000 --rx-freq 916000000.000000 --tx-gain 0.000000
--rx-gain 0.000000 --wave-type RAMP --wave-freq 10000.000000
Note this is 1 channel TX + 1 channel RX full duplex. Wire format is "sc16" (16 bits per sample over the bus I believe). Data format is "fc32" (32 bit float). I've tried both the stable and unstable UHD drivers.
I also observed that a moderate bend of the USB 3.0 cable will noticeably reduce reliability. Nothing too severe as to permanently deform or damage the cable.
I suspect RFI is affecting the USB 3.0 signals.
*** Questions ***
Any suggestions on how to achieve reliable 16 or 32 MSPS full duplex transfers? Hopefully reliable as in sustained full-duplex TX and RX or an average of 15 minutes between data transfer errors.
Has anyone placed their USRP B200 or B210 in a metal enclosure? Was reliabliity affected?
Has anyone tested their B200 / B210 with different USB host controllers and found a controller that is ideal for full-duplex TX+RX at the 16 or 32 MSPS rates?
Do full duplex TX+RX configurations create a significantly greater I/O challenge over USB versus TX-only or RX-only?
Or is the USRP B200 / B210 simply not the best hardware for doing sustained 16 or 32 MSPS full duplex TX and RX? Better to use a PCI Express interface SDR?

John,
Thank you for your time and help.
Yes I have posted to the USRP-users mailing list along with more detailed test results. I've also corresponded with Matt Ettus.
Thank you for the link to benchmarks. I later found that. I have stopped using the B200 with the computer with the NEC controller although it did give similar results versus the laptop with the 8 Series/C220. I am now just testing with the Asus Laptop with the 8 Series/C220 controller.
I do appreciate that the PCIe or 10-gigabit based SDRs are more reliable. Matt told me this too. I would expect this based on the prices. I am more concerned that full duplex with the B200 appears almost useless. Maybe my 8 Series/C220 controller has electrical or RFI problems? Maybe my B200 is defective?
I am concerned with the $5000 cost for a PCIe or 10-gigabit Ethernet solution when a PCIe x4 capable FPGA now only cost $100 or $200 more than the FPGA and Cypress FX3 that the B200 uses.
I'm tempted to instead spend $5K to roll my own PCIe MIMO SDR for $750 to $1000 per board versus spending $5000 for one X300, RF daugtherboard and external PCIe kit. And I can customize it to my needs better. Per Vices did exactly this and offered a $750 (later revised to $2500) PCIe SDR board with 100 MHz simultaneous TX and RX bandwidth.

See the other post. You need to turn off Direct Sound in the Device Manager properties panel for the card for full duplex.

HP Color LaserJet CM2320fxi MFP - Full Duplex Problem

Hello!
I've got LaserJet CM232 and Win7 (x64). My problem is that when I'm printing for example 4 pages of a document it's printing only in full duplex, so 2 pages printed on both sides. I can't find where can I fix this duplex problem, I'd like to choose manually if it will be printing in full duplex or not. Help me find a solution, please.
Second problem refers to the time of printing. When I print something I have to wait several minutes to print it. Is that a RAM problem? More RAM memory will resolve this problem?
Thanks a lot for your replies! I'd really appreciate any help!
Best regards,

Mac Pro 10.6.5 100baseTX Full Duplex Not Working

Hi Guys,
I am having some trouble with the Mac Pros that I support in my office (Early 2009 Model). Our network uses 100baseTX Full Duplex on all of our connections in a mixed PC/Mac environment. This was working perfectly fine until we updated our Mac Pros to 10.6.5 (Went straight from 10.5.6 to 10.6.5).
Every Mac Pro now has itself set to automatically detect the speed, and they keep setting themselves to 100/Half. If I go in and manually adjust it, setting it to 100/Full, I lose all connectivity to the ethernet (it doesn't even recognize that a cable is plugged in). This is causing a lot of troubles for our Mac users trying to access files on our shared drives. It is taking them about 5 minutes to download a 30MB file, rather than the 3 seconds it should.
I tried booting to our portable 10.5.6 drive and 100/Full works just fine. Our PowerMacs on 10.4.11 also work fine on 100/full. I tried using Cocktail and Sudo to force the change, but again the ethernet drops out. The problem persists through all user accounts on all the effected Macs. I have tried a fresh install of 10.6 and the problem persists. If I downgrade back to 10.5 the problem is gone. I know it is not an issue with the network because 2000 other machines are working just fine, and the affected ones work fine when downgraded.
I just spent a good hour on the phone with AppleCare, but after insisting it was a problem with our network for the first 45 minutes, they came to the conclusion that they simply could not help me. According to them, if I want networking help, I need to convince my company to spend $2,800 on their enterprise support, and even then they don't know if they will be able to help me. So, it looks like I am on my own here.
Anyone have any thoughts on what is going on or how to fix it?

The only possibility that I can see is that it is a software problem on these Macs.
There is always a certain level of slack engineering into all these devices. When you start updating one part of a network, you risk exceeding the slack. It is always possible that the problem is with the router hardware or cabling. Certainly, the problem would be with 10.6.5 too. But if you jump to one conclusion or the other without troubleshooting you risk waiting forever for a fix that will never come.
So, what you have to do is connect these Macs to some other router/hub running 100BT/Full (with settings as close to default as possible) with cables that you know are rated at that speed. If that fails, submit a bug report to Apple. If it works, take your router/hub and put it in the network cabinet and connect it to the Mac Pro with the existing cable. If that fails, sue whomever installed the cable and redo it (network people sometimes try to save money with cable). If that works, look at the existing router/hub and see if it has any bugs or firmware updates available. At this point, you could submit a bug to Apple with precise details about your router/hub and also submit one to the manufacturer of the router/hub. Apple will either fix the problem or contact the router/hub manufacturer and get a fix. Once you know precisely what connection is causing the problem, there may be other ways to address it either on the router/hub side or on the Mac side.

B200M3 and Vsphere 5.1 - Unable to set NIC speed to 10gb full duplex

Hi,
My first post here!
I got 4 B200M3 blades with VIC 1240 and 1280. I have installed vSphere 5.1 on them. The blades are configed with a number of NIC's.
The NIC's get a speed of 20gb full duplex(set on auto negotiation) and i would like to set them to 10gb full duplex. When i try to change it in vSphere i get an error message
"Call "HostNetworkSystem.UpdatePhysicalNicLinkSpeed" for object "networkSystem-1264" on vCenter Server "xxxxxxxxxxxxxx" failed.
Operation failed, diagnostics report: Forcing 1000Mbps or faster may not be supported on this network device, please use auto-negotiation instead"
After some searching it looks like you sometimes have to upgrade vSphere with new drivers to get these things to work?
Anyone got any ideas that can help me?

Hi Fredrik,
A few quick questions:
1) What is the driver type and the version on the vnics? here is the HCL for the required driver versions:
http://www.cisco.com/en/US/docs/unified_computing/ucs/interoperability/matrix/r_hcl_B_rel2.04.pdf
2) Did you install 5.1 direct or did you upgrade from 5.0? For this blade you need to use the CISCO OEM Custom ESXi image. We still do not have the 5.1 image published, however the 5.0 and 5.0 U1 are avaiable for use. Here is the download location:

Full Duplex Lost with Wave Files on SB Live! Value (W

Following a clean install upgrade from WinME to WinXP SP2 on a Dell Dimension 400 with an OEM-installed SB Li've! Value (WDM) PCI card onboard, full duplex wave audio (recording one wave file while playing back one or more other wave files) ups and disappears ? ME had it, XP doesn?t. The record side of software mixers I use on the XP OS (Quartz AudioMaster, NCH Swift Sound MixPad/WavePad) fail to acquire or record the wave signal(s) being played back by the mixer side of the application. Stand alone recorders (Roxio Easy Audio Capture, HotKey Sound Recorder) also fail to acquire or record the wave signal(s) being played back by the aforementioned mixers. But if I switch the record input to microphone during the record pass (on those apps that permit such midstream switching), the mic records without incident.
Creative?s Auto Update shows all drivers for the sound card are up to date. Applying Creative?s Knowledge Base Solution ID 645 passes all DXDIAG tests with no problems (text file results available if anyone cares to see them) but the manual test using twin Sound Recorders fails as the second copy (record-designated) Sound Recorder fails to acquire or record a signal from the first copy (playback-designated) Sound Recorder (no error codes display at any time). Clean booting WinXP and running the same record passes doesn?t rectify the problem.
Anyone know what?s going on here? And how to fix it's I?m stumped.
TIA . . .

For benefit of anyone who hits this thread in a search:
FWIW - Following 5-weeks of troubleshooting this problem with Microsoft Tech Support (including a parallel install of the XP SP2 OS), we reached the following conclusion: Since the OEM sound card (Creative Model CT4780) was known to operate in full-duplex mode without incident under my system's prior ME OS but the same card fails to consistently operate in full-duplex mode while running under a virgin parallel install of the XP OS, the source of my full-duplex problem must lie in the files and drivers resident on the XP OS CDROM and dropped to my system by the OS loader/installer. There really isn't any other plausible explanation. Absent its drivers, a sound card's nati've hardware state is either going to be full-duplex or it isn't - it would never be full-duplex sometimes and half-duplex (or simplex) the rest.
The problem was resolved when a retail, nearly identical, sound card (Creative Model SB040) and the drivers and files from its CDROM, were installed on the same system.
Perhaps, somewhere, drivers exist that will permit the CT4780 to operate consistently in full-duplex mode on an XP SP2 OS - but neither Microsoft, nor I, had any success in locating them.

Can I build a full-duplex serial port?

I want to build a full-duplex serial port with PCI-6533, main features are:
software: LabView
hardware: PCI-6533
serial port: full-duplex,synchronized
clock: 13MHz, external feed
control lines: 3
data: about 1k bytes to be transfered
Thanks and best regards,

You can build it, but it won't be easy. Transmitting should be OK. But, for receiving, you are going to have to parse the information out of your incoming bitstream to get the information from the frame.
Also, there is a peculiarity when usng the 2 timing sections together on the 6533. If you use any data width greater than 8 bits, you are only going to get 10MHz on each 'side', since the data has to be split between them by word. However, since you are serial and only using one bit, you don't have to worry.

Can not config full duplex on Gi0/1 of WS-C2960-24TC-L

Hi,
I have a problem when connect two modules GLC-FX-100FE to two switch WS-C2960-24TC-L as below:
When I plug each SFP module like above to each switch WS-C2960-24TC-L to SFP slot (gigabit 0/1: dual purpose port), then the duplex become to Haft.
So, I can not configure them to full duplex as other copper ports.
But when I use two switch WS-C3560G-24TS-S, I can do this.
OS version of WS-C2960-24TC-L I am using is: c2960-lanbasek9-mz.122-55.SE7.bin, I think it is new.
Please help me solve this problem.
I have to explain to our customer in the next morning. You know, I am Vietnamese and in Vietnam, the time is 22:40 pm,
Thank you so much.

Hi,
in interface configuration mode you have to configure
media-type sfp
Afterwards you can configure media-specific parameters like the duplex mode.
Note: Changing the media-type will cause an outage for a couple of seconds.
Hope that helps

10.6 update disables full duplex ethernet

Updated to 10.6 and immediately lost all internet connectivity. Network control panel reported "Cable Unplugged."
Restarted in 10.5.8 -- 100Mb connection worked fine.
Restarted again and back in 10.6, I fiddled with settings and found that by manually switching to "half-duplex" ethernet (under the "advanced" tab) internet connectivity returned. (Connectivity also resumes if I choose the "automatic" configuration, because that too switches over to half-duplex). Either way, the working connection seems a noticeably slower than 10.5.8, which I assume is the difference between half and full duplex.
Any ideas on how to restore the connection to full duplex?

Thanks for the tips
It is looking more and more like a driver issue with the Intel Pro 1000 card that came with the Mac Pro. I've found people with similar loss of full duplex with this card (sometimes unrelated to Snow Leopard).
Intel no longer supports the card or driver apparently, having sold that operation to www.small-tree.com. SmallTree's Web site states that a problem exists with the driver and Snow Leopard and offers a possible work-around at http://www.small-tree.com/gigabit-ethernet-driver-download-a/198.htm.
(The driver must be installed with the current ethernet card removed. Unfortunately, every how-to guide I've seen assumes you're replacing the easy-to-access PCI cards, but the preinstalled Mac Pro card appears to be hidden back behind the main fan and I don't see an easy way to get to it.
Am I missing something obvious?)

Network board 10/100 full duplex

I have an issue with my system (solaris 8 sparc):

I checked the cables etc but could not find anything.
ndd reports correct figures (100Mb and full duplex)
# ndd -get /dev/hme lp_autoneg_cap

Where should I look now?

Thank you for your help
With those parameters set, my bandwith is just worse so I came back to the previous configuration.
I tried hmeconfig (found on the web, a small perl script to display everything) and it showed:

* Enabled modes: 100-full, 100-half, 10-full, 10-half
* Link Partner supports: auto-neg, 100-full, 100-half, 10-full, 10-half
with default values (nothing in /etc/system) and:

set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=0
set hme:hme_adv_10hdx_cap=0
This sounds normal except that the second one is just slower for ftp exchanges.
I cannot understand this.

Sound problems, full-duplex not working?

Hi,
Im having a problem with sound, i use ALSA, and when i play a mp3 in XMMS i cant hear the sounds from other apps (as Gaim) until the song finishes and im presented with all of them at once, this means that i get the usual message recieved sound one after the other, until all the messages sent during the song are "heard". and the next song starts.
I think has something to do with full-duplex, but dont know where to look or fix it.
any help?

It doesn't have to do with full-duplex. Full-duplex is being able to play sound out of your sound card and record sound at the same time.
What you want is to be able to play more than one sound at once. Only certain cards and certain drivers support this (one is the emu10k1, the sblive), most don't. If you want to play multiple sounds at once maybe you should install a sound daemon like esd or artsd.

Half to Full Duplex

I am looking at an ASA5510 that is using the management port for several VPN connections. It has connected at 100/HD and I am not sure what will happen if I start trying to force that to full-duplex. Will this take down the port? Will it cause any of the VPN connections to drop? Unfortunately, this is a live box and an outage would not be good.
Any help would be appreciated. Thanks.

Will this take down the port? Will it cause any of the VPN connections to drop?
Changing port transmission settings on any live port either on asa or switch or router will bring down the port for few ms and brought backup quickly..but connections most likely will be dropped and will required to reconnect.
suggestion is to make port changes during non-production hours.

Checksumming/Full Duplex on WUSB-G w/SpeedBoost

Hi. I am using a wireless router for internet, and have recently had problems with the 2.01 patch of World of Warcraft. One of the technical suggestions they recommend is setting Checksum Overload to off, and 100x Full Duplex. I do not have either of those settings on my router.
Furthermore, when I try to login into 192.68.1.1, I am prompted for name and password. I leave name blank and enter "admin" (no quotes) for password, but this is not correct. I have never changed the settings of this router.
I believe it has the latest drivers (not sure of specific #)
If anyone can help me adjust the checksum and full duplex options, I would be grateful.
If it is helpful for resolving the greater WoW problem, I can post the description I left on the WoW tech support forums

Checksum Offloading is a hardware function of some high performance network cards - the card does the calculation and inserts the checksum into the packet. This reduces network overhead (CPU Utilization) on the PC.
The USB device does not have this feature.
You did not say what model router you have, but the manual can be downloaded from the www.linksys.com page under support -> Downloads - you need to select your model.
But the short answer is to press and hold the reset botton for at least 10 seconds. This button is located on the back of the router, next to the Internet connection - it is inside a small hole. You need a small pointed object to press on it (a straitened out paperclip works). Then you will need to reconfigure the router as it will be like it just came out of the box...
