• A non programmable power supply with LabVIEW + additional programming hardware

  My company is interested in the use of LabVIEW to automate a non programmable DC power supply. The instrument in question is the U8001A device, but the idea must be the same, regardless of the manufacturer (the instrument was purchased while I was hired, or I would have opted for one with SCPI commands if that's a thing for power supplies):

  http://www.Tequipment.NET/AgilentU8001A.ASP?source=googleshopping&gclid=CMn-rPzAks0CFZM6gQodMu4McQ

  We have two connectors that would be plugged into the power supply and in the 'brick' that holds some sample we want to warm up. This has worked well for our initial target, but we are now interested in time these events alongside 1-2 other instruments that we are exploited (for example a-ohmmeter for quality control), where we can control all this through LabVIEW. Say, only allowing the power reaching the sample at intervals of 5 seconds, with widths of 1-2 seconds impulse.

  I'm sure I'll need a multifunction data acquisition device, and I already have my eyes fixed on the purchase of the NI USB-6501 (link below). My main question is about any additional material which is necesasry, if only a debate of ideas cenceptual on what I'm trying to accomplish. I can do everything I plan only through the acquisition of data, or are there other necessary materials, such as doors? What type of material is suitable for it? I apologize if this is the wrong sub-forum for this topic, as seems to be the subforum of material more appropriate upon publication. Thanks for your time!

  Not even an analog command on this power supply... Range of tension and how much power do you need?  You may be able to make an operational amplifier circuit, but find out who can handle that many likely power won't be easy.

  Honestly, I say just to bite the bullet and get a programmable power supply.  It will be cheaper as you try to make a personalized tour to adapt to a peg in a hole square circle.

• (Amplifier) signal for system cDAQ conditioner!

  The system I want to build will be used to monitor the excitation of a motor/generator system. I have a couple of signal which are bellows 100 mV, for the example current measured with a shunt resistance to 40 / 60 mV.The problem is that I have what it takes to amplify the signal for more precision. Can someone provide me with a packaging option (low cost) material. I have at my disposal two NI 9201 and a NI 9205 card.

  Thank you have a nice day!

  Hello Padeanu,

  Please post on the Forums of Discussion! The 9205 already has a PGIA (Programmable Gain Instrument Amplifier) that amplifies the signal of your then you lose accuracy. According to the specs, you will get 174 uV of precision using the voltage range 200 mV and a width of 6.57 uV code / LSB. Your current configuration is too vague for you? Excitement for your engine system will be always lower than 100 mV, even when the motor is started?

• How can Hello I set a default printer with JAVASCRIPT? or send directly to a printer, I am programmer

  I'm a programmer and I need to print the 2 files in 2 different printers (with labels Zebra and letter to a strong), I have the sharp or default Zebra printer when I send the file to print, this take the size default to the default printer and it is printed with this size, a letter as a label and a label as a letter How do I set a default printer in JAVASCRIPT or send a file directly to a printer by JAVASCRIPT?

  How your web application user initiates not print function?

  There are two distinct "Print" buttons on the page? One of the labels for Zebra and other print of the 'letter' to the strong?
  
  Or is it a function of sequential type, where the label is supposed to be printed Zebra and the 'letter' to the sharp in one operation of button "print"?

• MacBook Pro will not play on the old stereo amplifier

  I'm playing together stereo music from Spotify or Youtube on an old.  I have my Macbook pro connected to speakers Audio Engine A2 (with integrated DAC) via the USB port.  Then form of the output of the A2s RCA cables go into my old fisherman amplifier CA-876 connected to NHT 2.5I speakers.  Music comes from the A2s but not the NHTs.  The counter on the sinner is not moving, it seems that the amp is not picking up the signal.  Thank you very much for the help!

  If you play other audio such as system sounds or local audio files it works there? If you connect the outputs of A2 to something that works? If you connect something else in the entrance of the Fisher does it work?

• When I plug my A100-003 on an amplifier, I get a strange noise

  When I plug the headphones off-one amplifier, I get a very strange and annoying noise, a noise that resembles a frequency. If I liked - headphone that noise disappears, it only happens with amplifiers!
  I'm a dj and I need plugin amplifiers all the time to play my music. Everyone goy no idea why this phenomenon occurs? Is my headphones off and needs to be replaced? * I bought the computer only 2 days before...

  Hello

  I know your problem because I had the same.
  One solution is to the mass of the laptop with your amplifier. Simply take a shielded wire, connect a tail of the wire to the groundconnector of your amp (usually for your turntable) and the other the tail to a point mass of your laptop. A connectpoint on your laptop can be for example the screws of your serial port or a VGA Port, or maybe with your SVHS-port.

• Digital input to Toshiba 46TL-> no analog audio output to amplifier

  Hi all

  When I connect a video source (e.g. computer laptop via DLNA) to my 46TL, output TV audio analog (red/white taken connected to an amplifier) does not work.

  It does, however, watching television.

  Is it possible to configure the TV to read the audio data from digital input (HDMI/DLNA) to the analog output?

  Thank you for the help

  Not quite what series of TLxxx you have, but for example the TL938 supports a digital (optical) audio output port that provides a digital audio signal.
  Why n t connect the amplifier to the TV using this Jack?

  Connectors for component video / audio to the rear of the TV are the ports of ENTRY and not the OUTPUT ports. So, you can send an audio signal to the TV and not the amplifier output.

• How to connect Apple TV to two different amplifiers?

  How to connect Apple TV to two different amplifiers?

  If you're talking about AppleTV 4 then there a single HDMI output only.

  You need either a HDMI switch or a divisor of direct HDMI to different amps (may not work at the same time due to HDCP) or see if an amp offers HDMI or optical output to the other depending on whether or not you want to distribute audio or video to the 2 amp.

  If you need a splitter/switch, it's an extra box and you might consider only 2 AppleTV, don't forget a rental on one will not be seen on the other.

• Audio problem Satellite Pro A120 when read by amplifier

  I experienced some problems when trying to music playing through an amplifier, with a cable of the headphone jack on my laptop connected to the auxiliary input amplifier: when the laptop is connected, the amplifier produces static and a high-pitched hum. Oddly, this only happens when the laptop is plugged into the mains. I don't think it's a fault with my amp, like the laptop, when it is connected to the network, also causes of interference with the LCD that I use with it. Is there anyway to fix this? Could this be a fault with the laptop itself, or the power cable?

• Toshiba 47L7453DG - CEC does not properly using exernal amplifier

  I bought Toshiba 47L 7453 a few days ago.

  It is connected to the amplifier Onkyo TX-NR535 but CEC does not properly. Volume control works fine but On / Off or stanby does not at all.

  My previous TV Toshiba 42XV635DG was communicated by the CEC with the Onkyo even without any problem.

  The wire connection is HDMI 1.4 certified.
  Maybe the problem is with the firmware of the TV.

  Maybe someone had the same problem.

  Any suggestion?

  Thank you

  Hello

  From my point of few TV and amplifier are connected some CEC (Volume control) functions that work. I think you should check the auto power settings and HDMI CEC standby control system.

  Manual, you will find some important notes:
  http://www.Toshiba-OM.NET/LCD/PDF/English/L7453-424755-English.PDF

  _Page: 11_
  + You can control the basic functions of audio/video devices connected with s TV remote if you connect an HDMI-CEC compatible AV amplifier or playback device. +
  + If several devices are connected, the HDMI CEC control function may not work correctly. +

  _Page: 86 - 87_
  + When the point to activate the HDMI CEC control in the menu of HDMI CEC control configuration is defined on.
  + On, also allocated to individual features will be activated. +
  + When the connected equipment work, HDMI CEC control automatically detects the TV input selection. If the TV is in standby mode, it will be automatically reactivated. +
  + If the TV is off (standby), television will send a message turns off (standby) all devices HDMI CEC control connected to the TV. +

• Re: Cannot run programms that requires OpenGL using the Satellite L

  I have a Toshiba laptop with ATI Radeon 4650, but cannot run programms that requires OpenGL.
  I can't install the new ATI driver on their homepage, because they are not compatible with the Toshibaproducts.

  I also can't update the driver from Toshiba, because their driver ATI latest is since March 2009.
  I already have googeld problem, but can't find it.

  Please guys, someone knows a solution to this annoying problem?

  > I can't install the new ATI driver on their homepage, because they are not compatible with the Toshibaproducts.

  Because ati - driver must be changed to support, protection against overheating.

  > I also can't update the driver from Toshiba, because their driver ATI latest is since March 2009.

  Yes, it may take quite a long time when Toshiba released updated Gpu driver

• Satellite A215-S7444 - name of the low frequency amplifier

  I need to know the name of aplifier of low frequency in a Toshiba Satellite A215-S7444 main laptop Board. I have problem with my speakers because they beep. And the problem is with amplifier speakers.

  Please tell me the name of this integrated circuit.

  Hello

  I think that no one here can answer this question because it s only a user to user forum and I have never seen anyone from Toshiba here. I think that this question can be answered only authorized individuals.

  I recommend you contact an authorized service provider. Technicians could answer this question and help you get a new spare part.

  Good luck!

• Mac mini as a media server connected to the hi-fi amplifier

  Hello

  I am considering a Mac Mini to replace my old Lacie Cinema player as my media center. It will be connected to television and, ideally, analog hi-fi amplifier for sound.

  Here are my questions and special needs:

  -want to browse my music library and control the Mac through my iPad or iPhone. Don't want to use the keyboard or the physical remote. Do something like plex installed on ipad control files that reside on the Mac mini (or external hard drive connected to the Mac Mini)?

  -as my amp is analog (with RCA plugs) I guess I have to convert the RCA plugs to the digital amplifier. A Mini Mac USB RCA DAC exist?

  I think that's it! Thanks for any help.

  The Mac Mini are very small computers.

  (for me, it almost seems like a waste to use as only a media center. I use my media center and an office at the same time)

  Not sure about this one. I am a user of office and control my media from there.

  -as my amp is analog (with RCA plugs) I guess I have to convert the RCA plugs to the digital amplifier.

  Everything you need for an analog RCA connection is a stereo 3.5 mm to RCA cable.
