SCXI with USB-6341

From a hardware standpoint, can a USB-6341 be used to capture data from an SCXI chassis (ignoring the connector/wiring situation)? I would like to use this scenario and program in C++ but the device access is controlled through MAX and MAX doesn't allow the USB device to be selected as a chassis communicator. It is my understanding that M-series USB mass terminated devices could be connected to SCXI so I'm wondering if it is just a list of compatible devices MAX uses and the USB version of the 6341 isn't on the list for whatever reason (which I would be curious to know).
In this note mass termination is called out specifically (for the M-series USB). What is the difference between mass termination and the wiring pin to pin?
I realize I can communicate with the SCXI in other ways but going through MAX would be much simpler for me (especially for calibration/troubleshooting) and I could use the NI provided DAQmx C examples.
Thank you

Unfortunately this is for work I do at home so I'm in the usual predicament of having to spend more time doing things myself where I can't afford to do it otherwise. I thought the device did have the APFI capability when I purchased it. Accuracy isn't a concern for me because I just need to see the signals (for example: high channel count temperatures where most devices are +/- 1°C on the spec sheets and I just need to know if heat transfer is working properly). I am trying to move away from a DAQcard that I was using for the SCXI to something USB that I can use with any computer in the future.
By the way, I'm only using bare wires inside the X-series enclosure. The cable is an EPM cable and I wired everything per the pinout diagram provided by NI for that cable. The BNC breakout I have wired to the SCXI chassis was working properly so I assumed it was good to go but couldn't get the device to show in MAX. Now I realize it is just the feedthrough on the 1349 that is working and communcation with the chassis won't work.
Thank you

Usb 6341 counter number of buffer

Hi
I will use usb 6341 to measure digital pulse.
What is maximum buffer when i use 25Mhz sample clock with buffered mode?
(It shown error when i set 25Mhz clock, N sample mode, 1M sample)
Is there any fast edge measerement with usb 6341?
(I want ns time scale with long time)
Thx

25 MHz is a very large sample rate for a counter... can you elaborate on your application? There really shouldn't be any reason to sample the counter this quickly. If you're trying to timestamp your external pulses with the highest possible precision, I would instead use the external pulse as a sample clock and count the internal timebase (assuming the external pulse isn't also 25 MHz...). Doing this would actually get you 10 ns resolution (instead of 40 ns that you are hoping for with a 25 MHz sample clock) and the required throughput would be based on the rate of your external signal (which is presumably less than 25 MHz, which is the highest frequency that you can connect through the PFI lines anyway...)
To answer your question though...
The on-board FIFO is 127 samples per counter. If your task is measuring more samples than this, you would need to be able to read data off of the device at least as fast as it is coming in. On USB that is going to be highly system dependant (one benchmark here reported 8 MHz). If you really need the higher throughput you are asking for you will probably want to switch to the PCIe version of the 6341 (20 MHz on a single channel mentioned here, I'm not sure if higher rates were tested but I wouldn't be surprised if 25 MHz is sustainable as well).

Software differences between USB-6229 and USB-6341 A/D boards?

I am writing code for a treadmill for wheelchair users. We are doing research with users of manual wheelchairs, and this second unit is very important for the clinic where we work. My OS is Windows 7. The Visual Studio is version 2008 (MS Visual C++ 2008).
The code is fairly well developed and has been running for 2 or 3 years on the USB-6229 DAQ board. We have built a second unit, and the people who built it tried to save a little money by purchasing a USB-6341 board (money is very tight in our research clinic, and it saved them about $1000). We were assured by NI customer service that the software would run with no changes on this slightly different board. The Analog outs and digital outs work great with this new board. However, I cannot read the analog inputs correctly. I do block reads where I read back 10 samples from 8 channels with a simple DAQmxReadAnalogF64 read. The data I get back is interesting. 2 of the channels are returning 0 or 1. 2 channels seem to have a relationship to what is going on, but is not at the right amplitiude. and the other 4 channels just have a slowly decaying signal. I have checked all 8 Analog inputs using NI Max test panels, and the A/D card is returning the correct data to NI's test panel software.
Any suggestions would be greatly appreciated!
Thanks!

Hi,
The programming for the 6229 and 6341 should be very similar, as both cards use the same DAQmx functions. You mentioned that you tried using MAX Test Panels, did you get the completely correct data when you were using the Test Panels? Also, does this codes still work with the USB-6229? Are you using differential, RSE, or NRSE connections?

USB-6341 and Temperature Measurement

Has anyone been able to measure temperature using thermocouples connected to the USB 6341? I have been told the unit does not have CJC, which is surprising to me. From what i see, there exists significant thermal variation when measuring temp with ta 6341. Has anyone come up with a method of using a thermocouple or RTD with a 6341 to measure temp?
Thanks,
Erik

I use the USB 6251 and 6351 to measure thermocouples all the time. There is the issue of the dissimilar metals at the device terminals adding to the measurement so you have to keep the box iso-thermal but that's not a big problem if you're careful. I usually just set the CJC to CONSTANT (25C) but you can dedicate an extra TC to compensation and stick it in a cup of ice water to get better accuracy. You still may not get the accuracy of dedicated TC interfaces but it's good to a degreeC or so and does very well indicating the relative difference between two channels. Wire up a couple TCs and test it out in your own lab before you trust anything though. Environmental noise can be problematic, especially with long wire runs.

USB 6341 versus 6215

I was using a USB 6215 OK. It worked great. However I needed to controll my valves by hardware I/O. I just installed the new USB 6341. I am trying to control 1 line at a time. I am currently sending a binary or hex value to control the valve. It does not act the same way as the USB 6215 DAQ. Does anyone have a simple approch to control one bit at a time. I am not familur as yet with the DAQ USB 6341.

Put the write function before the start function. The write function simply writes data to the DAQ card buffers. The data does not get generated until the start function is called. So in your code, you were telling the DAQ to write an empty buffer before you filled it with data. Try reversing the order and see if it works.
Sorry, putting the Start Task first is normal. Just look at one of the simple examples such as Write Dig Chan.
Normal, maybe, but not always so. Look at the example called Write Dig Chan-Ext Clk. It has the write before the start. I guess it works both ways. I have always put the write before the start because I have sometimes used external triggers. That lead me to believe that you have to write to the buffer before you start the task. I do the same with Analog Outputs also.

IPod nano works with USB 1.1 but not USB 2.0

Anyone using an iPod nano that works with USB 1.1 but not with USB 2.0? I am using Windows XP and when installing the iPod software from CD it recognizes the iPod and am able to transfer songs using iTunes but when installing SP1 or SP2 to enable USB 2.0 transfers, Windows XP only recognizes the iPod nano as a USB Mass Storage Device. This is the same with iPod Updater.

I have a similar problem with the following configuration:
- Dell Dimension 4100 Desktop with 2 integrated USB 1.1 ports, Windows 2000 SP 4
- PCI 6-Ports USB 2.0 Card ("Mentor" resp. www.bona.com.tw), Model USB20-PCI/6P
What works well?
- All my USB add-ons (1.1 and 2.0) on the internal 1.1 ports as well as on the USB2.0 PCI card
- iPod Nano 4GB on internal 1.1 ports (external drive in windows 2000 as well as iPod in iTunes)
- iPod Nano works as well as on the USB 2.0 card ONLY WHEN my old 4-port USB1.1 hub is connected between Nano and USB card
What doesn't works?
My iPod Nano directly connected to the USB 2.0 card. Symptoms when connecting:
- Windows is very slow, process "scvhost.exe" or "system.exe" using 99% of CPU for some minutes
- iPod is recognised as external drive, but when I click on it, it is empty and copying files to it results in "I/O error"
- iTunes doesn't recognise the iPod (of course, if even windows itself cannot read from it...)
I removed all USB drivers, reinstalled iTunes, iPod (by the way, I still don't understand what "iPod update" is good for, except for updating the iPod's firmware), deactivate the internal USB1.1 ports, no result.

HP ENVY 6t has many issues with USB headphone, Bluetooth and more serious issue

HP ENVY 6t doesn't work with USB headphone, unfortunately. could u let me know how to fix it?
Bluetooth mouse has been working for a day, it suddenly stopped working. Having checked the PC bluetooth connection, which said "Working properly". Could you let me know how to re-connect, or re-work?
"Not complete shut-down" blue screen issue right after receiving the HP PC when I closed display to be in sleep mode.
I see the "Safe mode" "...." or "Normal mode" screen always.
The HP PC is not stable UNFORTUNATELY.
Even if just brand new HP PC, there seems to be many issues.

I would recommend using this document for your mouse: http://goo.gl/XDRRy
And using this document to troubleshoot your headphones issue: http://goo.gl/hV9fu
Most of the time with USB headphones, you have to download the driver from the manufacturer before they will work properly.

How do i let my iphone connect to my computer wifi with usb ?

As the title stated,
How do i let my iphone connect to my computer wifi with USB ?
The reason is because my iPhone 3Gs wifi having some problem. So i have to use a USB cable to connect to my computer and let my iphone to connect to the internet .
If i don't do this i would have to keep on running out & in to my room & my living room.
My iPhone 3Gs allows to connect to the wifi when i am in my living room, but once i enter my room the wifi won't be able any more. So please help me out please people
I'm not sure about why i can't connect to my Ad hoc even it's so near, but i can connect to my router if i am in living rooms.
Regards,

I believe the next time you sync your phone to itune via the cord, you will have to check the box that says sync via wifi and also enable that setting on your iphone.

Connectivity Issues with USB 3 ports on macbook pro

Hi, I have a zoom r24 which is no longer working as an audio interface with my new macbook pro. I have read a lot about issues with USB 2 devices not being compatible with USB 3 ports on the macs. This seems to be midi as well as audio devices. Can anyone recommend or point me to a list of supported devices for both audio and midi which are guaranteed to work with a late 2013 macbook pro retina display. I cant afford a thunderbolt device. Thanks steve

Just a wild thought here, but have you tried inserting a powered USB 2.0 hub between the MacBook and the interface?

4s Hotspot tethering only works with USB and BT but not with wifi

Hi,
XP sp3 - iPhone 4s with ios 5.0.1 - on Three one plan
Tethering with wifi works to a friends Samsung phone, wifi on the pc confirmed working with the apple store wifi, tethering with USB and BT works with good connection speeds on my laptop but when i try to tether with wifi it connects to the laptop at 54mbps and all appears well, even claims to have received a small amount of data packets, but no data comes to any browser. The iPhone reports 1 connection to the hotspot and stays connected with a non-pulsing blue bar after the first minute.
In the PC i have tried this http://windows.microsoft.com/en-US/windows7/Change-the-order-of-network-protocol -bindings
I've deleted my firewall (zone alarm) completely and turned off windows firewall to go naked surfing for a second even though they don't cause a problem with USB tethering, makes no difference
I've deleted the network connection numerous times
"repaired" connection
dissabled and enabled the wifi
turned off the wireless with a hardware switch and on again
disabled bluetooth
rebooted many times
reinstalled itunes (latest)
loads more things i can't remember
This is causing me a nightmare. I've been through everything i can find online, been to the Apple store genius bar (genius appeared to have sub zero knowledge / interest as it involved a MS machine), been to a Three shop (legally not allowed to touch my PC apparently) and been to a Sony shop (laptop make, not their fault if my iphone doesn't work). All very frustrating.
Please help if you can! Any suggestion will be tried unless it involves sledge hammers or lakes, and only then for a few more days at most.

Turned off bluetooth on phone, turned off hotspot and on again, phone asked if i wanted to turn on bluetooth or go with USB and wifi only, said usb/wifi only. Still nothing. Rebooted PC and iphone. Turned on hotspot, pc seemlessly connects to network, still no data comes.
One odd thing is zone alarm asks me to "select a security zone for the wireless network at ip address: *******.0" every time and doesn't seem to remember the setting over sessions. When i get the status of the connection the ip address is *****.2 and default gateway is same ********.1 Not sure if that's anything.
Also getting a javascript error about an undefinded component (trustcheckermozilla) since i updated zonealarm but as i said even completely uninstalling zonealarm made no difference. I'll update firefox as well but tried with IE and still no data.

K7N2 deltas mainboards have a problem with usb devices ??

Ok here is my problem..
I had installed WinXP Pro with SP1..
I got a 20 GB USB2.0 disk.i connected it on the both front or rear usb ports.
When i tried to transfer files to my usb disk or to my PC, in the middle of the copying, i got "Write Delay Failed" error and lost my usb connection..
I had to plug it out and in again..
Now, i have an DSL modem..Last night, i was disconnected from internet and my modem's lights gone..I plug it again, no lights..restarted my PC, also completely shutdown Windows XP..Again no lights..
Then, formatted PC and installed windows 2000 Pr and SP4, until now, my modem worked fine..But USB 2.0 ports are still no use for my usb disk...
In bios , it's enabled as USB 1.1+2.0..
I think this K7N2 deltas have a problem with usb 2.0 devices and Win XP Pro..
Some guys talking about, removing 9th wire earth, but couldn't understand which wire from where ? From mainboard or from usd device's cable ?
Those cables are fabricated, i think it's impossible ?
My processor is Athlon 2500+, ram Twinmos 512 DDR 400
Thanks for reply

I'm also having this problem. It's happening with my USB flash disk. I was almost buying another one when I tried it with Windows Vista on the same machine and it worked ok, then I tried Arch Linux (with kernel 2.6.30.5) on another machine and got the same error. After that I tried Ubuntu and it worked ok. Seems that Arch's kernel doesn't like my USB flash disk.

Hi I'm trying to install an HP C4180 printer as net printer through Alicegate router (Thompson technicolor). Printer works ok when connected with USB to Macbook air, but cannot be seen on the printer installation configuration. Mac OSx 10.7 (Lion)

Hi folks.
From this morning I'm trying to "see" an HP printer C4180 connected on the USB port of the wi-fi router (TIM Alicegate ADSL2 Wifi+N, manufacturer Technicolor).
I installed latest drivers and checked everything is ok and works fine until printer is connected directly with USB to my Macbook Air.
Then I connect the USB to the router and try to find the printer.
On Alice help suggest to find it by ging to system preferences, then printers, add printer with "+", select "windows" sheet. There I can see - not always in reality, but sometimes - the "workgroup" in the left column, select, "alicegate" in second column, select, and here instead of finding the printer list there is a pop up saying that "the server version you are trying to connect to is not supported".
Reading other forums, it may seem that the problem is Lion not yet supporting this kind of connection.
Here a photo of the situation when the message occurs:
Help..

How can I stop iTunes from dropping my iPhone 5 when connected with USB cable? It sees it and start a backup and then it drops and tells me cannot find phone.

My HP notebook 64 bit Windows 8 after the last iTunes update will detect my iPhone 5, sync and when finished with thy sync I start a backup to my computer. It runs fine for a bit and then gives me message I have changed settings on my iPhone 5 and asked me if I want to update. I OK the question and runs a bit more and then drops the connection telling me cant find my iPhone 5. I can restart iTunes and start over and does the same thing.
ITunes update 11.1.1.62 had difficulties with the updates on 64 bit Windows 7 and 8.1 causing an error on boot other trouble. I found solution on research that insturcted to Remove iTunes, Bonjour, Apple Support and Apple Update and reload iTunes old version. I simply reloaded the new version becasue did not have the old version of iTunes. I have been working fine with the old version. I know problem is a simple setting somewhere but it is NOT SIMPLE to me since I dont know where the find the simple setting.
Will someone tell what to do. I appreciate all you smart guys.

My apologies...the version is 11.1.4.62 not as stated aboive in my problem description. I'm trying again and it just finished syncing fine and my iPhone 5 is still connected to iTuns physcially with USB lightening cable and is displaying the iPhone icon top right. I clicked on it and iTunes is now "hung' or locked up. Shows to be an active running application but can't get back to it so willl have to kill with task manager. There is some kind of problem going on with the latest version of iTunes and Wndows 7 and 8.1 or something. My iPhone 5 now has a new feature that it is now asking me if I "Trust" this computer. iTunes just came "unhung" after several minutes while I was typing this. Now I am going to start the backup to this computer HP Winsows 8.1 and iTune 11.1.4.62 and see what happens. Says it is Backing up Jerrys iPhone but the Barber Pole progress bar is not turning an iTunes is hung again and I cant get back to it from this page I am typing on. Maybe it will eventually release as it did a moment ago.

Two Finger Right Click on late G4 iBook with USB Trackpad?

I learned that with OSX Version 10.4.7 it is possible to use the two-finger-click instead of ctrl-click for right-clicking. But this only works on the new Intel Macbooks/Pro. Well, this is nice.
For older Laptops with ADB-Trackpad there is a freeware program called iScroll2 which also provides this feature.
For the late 2005 G4 iBooks with USB-trackpads there is apparently nothing:
The feature doesn't come with 10.4.7 here and iScroll2 is ADB-only.
On the one hand I don't really get the problem here, why these machines are not supported.
Since there is no announcement from apple it seems that they are just not interested in supporting computers which have been sold till not even a year ago.
If Apple is definitely not planning to support this in the future I would at least expect that they publish the source for the USB-driver so that the open source communitiy can take care of the problem.
G4 Ibook, among others Mac OS X (10.4.7)

have you tried installing iScroll? I'm pretty sure it
should work...by USB trackpad are you referring to a
trackpad plugged in to your USB port?!? (".)
Maybe I didn't explain it clearly enough in my OP:
The late G4 iBooks have a "Apple Internal Trackpad" which is a USB-Device, whereas older models sport an ADB-trackpad. In the late iBooks ADB is no longer present.
On the iScroll2 page (http://iscroll2.sourceforge.net/) you will find the following information:
"Models that have two-finger scrolling already built-in are not supported! These use a completely different, USB-based trackpad, the driver or which is not available as open source. iScroll2 is based on Apple's AppleADBMouse-209.0.10 driver for the ADB-based trackpads found on older models, which is available as part of the publicly released Darwin source code.."
So again: The feature mentioned in the topic is not provided by Apple, nor is the USB driver source code publicly available making it quite unlikely the OSS community will come up with a solution.
