• What type of modem do I need connect my AirPort Extreme to BT infinity

  What type of modem do I need connect my AirPort Extreme to BT infinity

  The question is not really what kind of modem you need... it is rather one of 'approved' modems which provides the BT will be compatible with the AirPort Extreme.

  Unfortunately, the AirPort Extreme and other Apple routers are designed to work with standard DSL and cable type connections.  The fiber is a new ball game, and Apple has not yet learned all the rules for the new game.

  Your best bet would be to publish a list of 'approved' BT here modems and then ask other users who might have the same product and an AirPort Extreme about their experience.

  You can also just ask BT what product they would recommend to work with the AirPort Extreme.  They tell you that they will not support you if you are using the Apple product, so maybe it's something to consider as well.

• A motor with encoder closed loop. Can I connect an other encoder without using an engine and double regulation?

  A motor with encoder closed loop.  Can I connect an other encoder without using an engine?

  Thanks to LabVIEW with a PCI-7332 and an UMI7774 interface to control a stepper motor with encoder feedback.  System is configured in closed loop for the control mode.  You will need to add a different encoder to the system without attaching a motor.  I'm validation of encoders to each other.  Is this possible?  Should what kind of latency I expect?  I have attached a simple vi.  Need to buy one before the answer.

  Thank you

  You can just plug the second encoder to the second slot without an engine it. Then you can use reading encoder Position.flx to read its position or do whatever you want with it. What about latency times, how are you trying to go under?

• Erratic counting quadrature encoder

  Hello

  I try to use LabVIEW 9.0 and an acquisition of data USB-6212 for measuring angular displacement of rotating quadrature encoder (digital model we E2) attached to a linear actuator based on the stepper motors.

  With the help of the VI linked to below and the default PFI pin on the acquisition of data, I can get the Angle of the VI to change, but with two issues indicator.

  http://forums.NI.com/attachments/NI/170/144774/1/QuadratureEncoderM-series.VI

  1. the only way I can assure you that the Angle indicator remains at a constant value with the VI running and the stepper motor moves do not is to turn off the power to the encoder.  In other words, when the 5V power is provided to the encoder, the Angle indicator sometimes remains constant at a certain value and sometimes increases, even if the motor step does not move.  I added a waveform table that displays the Angle to see more easy output.

  2. with the engine not to not pass any if she moves hourly or counterclockwise, the angle indicator only increases (counting).  Changing the direction of engine displacement does not decrease the angle.

  I checked the DAQ pins I use: PFI 3, Z = A = B = 11 PFI with ctr and PFI 4 1.  I tried both ctr0 and ctr1 with the same results.  I used a multimeter to check the outputs a, B and Z on the encoder to output with the motor step-by-step to displacements of various populations, and I'm getting ~ + 5V sometimes and ~ 0V sometimes telling me that the encoder, which is new, seems to move from high to low.

  This sounds like the kind of behavior that may be caused by noise in signals?  If so, who should not have something to do with the Angle only, correct?  To get the Angle to reduce, should I change something in VI?

  I thank you very much for any assistance, you can give.

  Hi Mike,.

  From what you describe, I feel the symptom of the meter backwards never is a side effect of the issue where the meter continuously counts up while in not moving.  This really looks like a noise problem, and there are a few small but noticeable spikes in your graphics HAVE you provided.  Basically, as long the (Source) Signal led B Signal (to THE), then the meter progressive count.  This is for X 1 coding, which I assume that you are using.  Look here Figure 5, in virtue of the X 1 section for how this encoding reads your signals of encoding:

  

  Your connections you describe are correct, so it'll be a matter of getting rid of the problem where the meter is incremented on its own which I believe will solve your other problems.  Take a look at these links to see if adding filters on the internal counter inputs to the card allows the measurement: Activate the digital M series filtering  allowing digital filters for TIO Debounce NOR-DAQmx devices

  Your MacBook Pro has built in WiFi.

  Wi - Fi

  802.11ac wireless Wi - Fi network; IEEE 802.11a/b/g/n compatible

  It is the best way to connect. You will need a router if you don't already have one.

  If you want to use ethernet wire you can use this cable. ter http://www.apple.com/shop/product/MD463LL/A/thunderbolt-to-gigabit-ethernet-adap? fnode = 8 b See the following link for more useful information if you are new to Mac.

• What is the fastest connection that I can use for a new external SSD for my MBP late 2008?

  That IS the question. I want a new external SSD for my MBP late 2008.

  What is the fastest connection type that works?

  'External' and 'SSD' could be a problem.  SSDS are different animals of disks spinny.  Some will say that you need not trim on SSD (TRIM is a management tool to move only the ' opportunity' bytes in a block when the block of data is moved), but definitely TRIM does not work on USB or Firewire.  Not sure if the TRIM works on Thunderbolt connected readers as it does on disks SATA-path, however.

  Speed included between slower and faster, however: USB 2.0, Firewire 400, Firewire 800, USB 3.0, love at first sight.

  Thank you.

  Hi Michael

  It seems that you are really a beginner. Am I wrong?
  Laptop you seems to be a new-generation aircraft and in my opinion it should be already delivered with the internal wireless card.
  If you are not sure if you unit has inside wireless network card you can check this in the device under network adapters Manager.

  The wireless network card must be activated with the switch on the side of the laptop and with the FN + F8 key combination.
  In addition, the access point or router WLan is necessary to use wireless networks.

  Wireless technology is a long story. I recommend google a bit for more details.
  If you have trouble with the connection that you could post again.

  What do I need install the second hard drive HP PAVILION: p6633w?

  Hello

  You need two cables, one is a sata cable:

  http://www.play.com/PC/PCs/4-/30305659/706331346/STARTech-com-6in-SATA-to-right-angle-SATA-serial-ATA-cable-female-SATA-female-SATA-6-inch-red/ListingDetails.html?_%24JA=TSID:13315% 7Ccat: 30305659% 7Cprd: 30305659 & kw = {keyword}

  This cable is only for data and connect the hard drive to the SATA connector on the motherboard.

  The other cable is energy:

  http://www.itpartsdirect.com/STARTech-15-24cm-4-pin-Molex-to-SATA-power-cable-adaptor.html

  It connects the hard drive to the PSU.

  You can also buy a combo like this cable:

  http://www.Amazon.co.UK/DP/B00064GBT4/?tag=hydra0b-21&hvadid=9550951989&ref=asc_df_B00064GBT4

  All you have to do is to connect the hard drive and that's it. Make sure that the main drive with the operating system is connected to the primary SATA connector (I think there are the numbers 1, 2, 3...)

• 2nd hard drive for HP Pavilion dv7t-4000 CTO Notebook - what do I need?

  Hi, I have the HP Pavilion dv7t-4000 CTO Select Edition Entertainment Notebook (product # WV703AV). It can accommodate two hard disks but only came with one. What would need to be able to install the second hard drive? I need just a connecting cable or I also need to caddy or kit?

  Also, would I get a solid state? My laptop that would support or should I just use regular?

  Currently, I am on Windows 7 64-bit. I have a 500 GB hd (which came to be partitioned with hp tools/restoration).

  Help with what I would need to a conventional hard drive or ssd would be greatly appreciated. I tried to look through messages of others first, but could not find anything specific to my model. Thanks for your time!

  Hello:

  The only place I know where you can get a 2nd hard drive kit is that provider.

  http://www.newmodeus.com/shop/index.php?Main_Page=product_info&products_id=345

  Your laptop should be able to work with an SSD, but I can't guarantee it.

  I don't really see any point in adding an SSD unless you make the main hard drive, and to do this, you must get an SSD of the same size as the original 500 GB hard drive to use the recovery discs to reinstall the operating system.

  Most people get smaller SSD and they use the W7 product key to activate a simple installation of W7.

  If you can read all 25 characters of your product key for windows 7, you can do your own installation media and allows to install Windows on a smaller than 500 GB SSD.

  If you can read the Microsoft windows 7 25-character product key, you can download simple Windows 7 ISO files to burn on a DVD for the version of windows that is installed on your PC, and which is listed on the Microsoft COA sticker on your PC case.

  Burn the ISO with the option to burn the ISO on your DVD burning program and burn it at the slowest possible speed that will allow your program. This will create a bootable DVD.

  Or use the installation of Windows 7 USB/DVD tool to compile the ISO file that you download from Digital River. The link below. You need a 4 GB flash drive to use the USB compilation method.

  http://download.CNET.com/Windows-7-USB-DVD-download-tool/3000-18513_4-10972600.html

  Use 25 characters on the PC product key to activate the installation.

  The key will activate a 32 or 64 bit installation.

  Then go to the support of the PC and driver page to install the drivers you need.

  Link to downloads ISO of W7 is below.

• 9401 counting by quadrature encoder error

  I use a 9401 module in a chassis 9188 to measure the position of a tree in 1E6 County/rev. The signal is an AQuadB emulated from an AKD Kollmorgen servo drive. My problem is that when the player is turned on, the noise it makes picked up as very positive figures by the 9401. The player has outputs RS485 but my cable length is short and well armored, so I thought it would work very well. It is wired like this:

  9401 CTR1 channel

  A +: 9401 pin 20

  B +: 9401 pin 23

  GND: 9401 commune

  The cable shield: 9401 commune

  Is this product because the encoder signal is differential, or is my bet to the ground/shield OK? If I disable the encoder entirely the 9401 picks up a zero solid. Should I use a kind of RS485 converter to TTL?

  In addition to the advice of John to help protect against digital noise, I also recommend that it would be a good idea to convert the differential asymmetric TTL formally.  I had opportunities in the past where I had an ambivalent connection channel differential encoder of 5V to a DAQ card and often, it would work properly.  But there have also been moments where differential signals (-) were trying to drift over the other while being tied to the digital earth common DAQ, causing sporadic but strange counting behaviors.  At least that's the diagnosis I'm come up with at the time.

  These questions disappeared immediately and permanently after putting in a differential to the TTL converter.  Here is a link to the productI used (and then successfully reused on the following projects).  Just check the specifications of your particular differential signals compared to what this product is to spec'ed to manage.

• VI quadrature encoder does not work after programming of FPGA

  I'm rather new on the MyRIO, and I work on the motor of the MyRIO and read control in a quadrature encoder at the same time. Programmed individually, the two pieces of work at Marvel, but once I have combine them and try programming, control of motors not to not work signals, but the reader encoder does not work. I use the Express VI for the LabVIEW quadrature encoder reader, and I produce four stepper motors signals using FPGA.

  It seems as if the encoder is disabled when I program the FPGA with my code, because if I have two parallel loops, one for the reader encoder and the control of step motors, if I stop the loop of step motors, the encoder works immediately.

  Is there something simple that I'm missing?  Any suggestions would be greatly appreciated!

  Thank you

  Enan

  I realize now that my last answer could have been confused and not useful to someone else who may come across the same problems later.

  Here is how I solved the problem I've had:

  I had to derive Boolean expressions for an encoder quadrature (essentially to create my own) and then used the outputs (UP, DOWN) to increment/decrement a counter using the conditional statements. Then, I stored the value of direction in a flip flop implemented using two conditional statements of T/F in series and connected to a shift on the edge of the loop register.

  It was all able to be implemented in a single cycle timed Loop, and then I managed to place in the same loop that I used to control stepper motor.

  In this way, I could have a VI collected in a Bitfile and could be programmed to the FPGA.

  Hope this is clearer!

• quadrature encoder synchronize the sample

  Using a USB-6251 housing measure a quadrature encoder, I will determine the angle that external discrete changes state.  I tried to connect the unobtrusive to a DIO of entry and using code CVI PC read the angle of the encoder, when the state change occurs.  The problem is the lag time of the PC code that adds up to 4 degrees (with a variability) to the measured angle.  An ideal solution would be to trigger a measure in a buffer in the USB-6251 housing when the State of the discrete changes, then read the value in the PC at a later date.  Is this possible with the USB-6251 housing?

  Thanks Adam,.

  I solved my problem by using this idea with the addition of the use of sampling buffered and discreet as a trigger.  Engaging the material task also seems to be a good idea, but may not be required.

  The installation code looks like this:

  Start a way to encode on the counter 1 to control the angle of the label sensor PNP edges
  status = DAQmxCreateTask ("PNP Rising edges", & pnpTaskHandle);

  strcpy (chanString, devName);
  strcat (chanString, "/ ctr1 ');

  status = DAQmxCreateCIAngEncoderChan (pnpTaskHandle, chanString, "", DAQmx_Val_X4, 1, 0, DAQmx_Val_AHighBHigh)

  DAQmx_Val_Degrees, 4096, 0,0, "");
  sprintf (chanString, "/");
  strcat (chanString, devName);
  strcat (chanString, "/ PFI1");
  status = DAQmxCfgSampClkTiming (pnpTaskHandle, chanString, 1000000, DAQmx_Val_Rising, DAQmx_Val_ContSamps, 10)

  (0000);
  If (status<>
  DAQmxGetErrorString (status, errString, 1000);
  DAQmxTaskControl (pnpTaskHandle, DAQmx_Val_Task_Commit);
   
  Start the task
  status = DAQmxStartTask (pnpTaskHandle);
  angleTaskStarted = 1;

  Read the value of looks like this:

  status = DAQmxReadCounterF64 (npnTaskHandle, DAQmx_Val_Auto, 0, npnEdgeArray, 1000, & npnSampsRead, 0);

• How to read a quadrature encoder, using a PCMCIA card from 6036E?

  Hello

  I 6036E PCMCIA card and I want to read a quadrature encoder.

  I must not use the z index.

  My version of Labview is 8.5.

  When I try to use the DAQ assistant and choose the option 'angular position' I get the answer that no supported device were found.

  What should I do?

  Thank you in advance,

  Fotios

  Hello

  Card PCMCIA-6036E has a STC chip that does not support the encoding position because there is no support of Z. It must be resolved in the software and using the edge counting.
