• maximum VGA resolution on mac mini

  Hello.

  We bought a mac mini to run experiments with an old SONY trinitron CRT. Before, we used an old mac pro with an adapter DVI to VGA and could go up to 1280 x 960 at 100 Hz. Now, with the new mac mini (model 2.6 GHz) and mini-Display to VGA, we can go back only 90 Hz at 1280 x 960 (and it was not yet in the Panel by default). If we go up to 1280 x 768 or 1024 x 768, we can increase the refresh rate of 100 Hz but the resolution is too low for us.

  So why can't use us the same resolution and frequency of refresh as before? The monitor and the VGA cable can manage the resolution. The limitation comes from the graphics card of the mac mini? If this is the case, it's pretty terrible. It comes from the mini-Display port? So, why use a port that have less than the antiquated technology VGA resolution? Is this a limitation of the display mini converter VGA? If so, what are workaround?

  Thank you very much.

  Kind regards

  Not sure to be honest. I have the model of 2014 with the 2.6 GHz CPU. I'm running a screen adjustment 2 x 1920 x 1080 double digitally, and it works beautifully. Maximum supported is 2 x 2560 x 1600 for our Mini according to the manual.

  My guess would be that your Sony CRT and the chip Intel Graphics Iris do not like each other much.

• Effect on correction of the CJC to use copper instead of type thermocouple extension cables

  Hello people. It is is a kind of "phenomenological" question, lumping together a bunch of real problems. Type of hope that someone had experience try this and can give me an advice.

  I'm looking to make measurements of temperature relatively high speed with very fine wire of type K or N thermocouples.

  I will be very many TC - about 75 in quantity and therefore will be, if it works well enough, wire the asymmetrical (I trading accuracy for amount in light of the SCB-two 68).

  My complete data acquisition system is:

  Computer PXI

  PXI-6225

  (Qty 2) SCB-68

  QUESTION 1: Any recommendations in the configuration of these two NRSE or GRSE? The device, I am close to (but not electrically in contact with) is completely without merit (experience of combustion). TC fine wire is indeed very thin, and their not armoured lengths will be about 12 ". There is no significant EMF/EMI around my experience. I will experiment but just wanted to know if anyone can rule something here...

  QUESTION 2:

  Important points:

  • I want to use type N for additional above K to my temperature range and also because that N-type are available in smaller caliber (0.003 ") and stability welded end to end.
  • Unfortunately, I n ' t has a bunch of N type connectors - if I have to use/buy the N type connectors this is a significant cost (see the stop).
  • My Setup has the TC in the physical location of 'groups' of 7. Given the asymmetric configuration, I have 7 anodes and 1 single "reason" for each "group" - for a set of 8 wires out of each "group".
  • I need to connect on the order of 80-wire in both SCB-68. I try to minimize the number of threads that I have to deal with.
  • Omega does not sell single conductor wire anode and cathode for the N-type as they do for K-type. They sell only duplex son.
  • Omega is also not sell armored bundles of type N, as they do in K-type
  • If I use type N TC and I use the real N type extension wire, it will have to be duplex (because of two previous points) - it's something like 80 PAIRS of wiring, with one of the sons of the cathode on most of the wires not used (because of the asymmetrical configuration).

  It seems that I must consider the following compromise:

  Use the TC type desired N and treat approximately 80 pairs of duplex wire extension of type N OR less desired TC type K and purchase grouped, shielded wiring to minimize the mess of wiring GOLD copper use extension (WHAT?)...

  Yes! Why can't I use the copper wire extension to the fine N TC of the cable type and connect to the TC with a kind of nonmetallic connector (like screws nylon) or solder? The attraction here is that I could use the signal wire 8 drivers together, to each of my TC 'groups '. This would reduce and clean my wiring and not need to buy all type N connectors (TC would be wired, no connector involved).

  It seems to me that I could simply set up the cold welding (CSF) on board the SCB-68 fixed to work on N-type. Copper wire would result of the SCB-68 the TC type N. No metal connectors would participate. Thusly, being only one junctions P/OMEGA-copper and copper/OMEGA-N to deal with the CCM. This sounds like it would be exactly the same as a N-type wiring directly into the SCB-68, except that there may be error between the temperature reading to the CJCS and the junction of alloy copper/OMEGA real. This won't be a significant error because the two locations will be very close in temperature.

  If this "mistake" of temperature becomes a concern I can mount a TC that is unique to the copper/TC junction and make my own corrections (I think...)

  Here is a little schematic text (without taking into account all shunt connections in the CSR circuits...):

  Any circuit anode/channel: SCB-68 Terminal-> extension copper-> (direct connection via the non-metallic connector) OMEGA-P of the N type TC

  Common ground circuit/channel: SCB-68 Terminal-> extension copper-> (direct connection via the non-metallic connector) OMEGA-N to the N type TC

  This idea implies that the circuit board within the SCB-68 has copper conductors, such as the addition of copper extension wire would not create an additional junction.

  Anyone tried this? Can someone offer me some ideas?

  THANK YOU in advance!

  Henrik-

  Thanks for the very useful reply. Yes, I forgot to mention that the lengths of wire extension will be the order of 1 m, then resistance extension must be low, even if common ground is used as part of an arrangement of asymmetrical circuit.

  ...

  Here's my last logic!

  • If my experience shows that the single-ended NRSE GRSE arrangement response or "match" the differential response conservative, I will choose asymmetric for more sampling points.
  • Since I know the extension wire / TC to the ASE will be nearly isothermal with the CBS itself, I would like to use the extensions of copper and accept (and possibly correct?) the error based on the temperature. I would like to use threads, as this I need 7 + and 1 ground by grouping of 7 TC to my DUT (Recalling)-> http://www.newark.com/jsp/content/printCatalog.jsp?cat=c127&page=1199&display=zoom
  • If during the examination of the previous point, I find that copper extensions are NOT practical and I need to use tank extensions of TC-metal all the way, then I choose a TC type K on an N-type. The reason is that there are many more options for tanks, bundled extension cable type K (N-type is apparently a sort of new and not very popular). However if copper extensions are possible, then I'll use the TC type N, motivated by their superior high temperature oxidizing atmosphere stability and the fact that I can get them in a configuration welded end to end to 0.003 "caliber!

  If none of this logic seems faulty or unrealistic, I would appreciate it really more input! I don't know that it will be a lot of work!

  Thank you once again,

  -Dan

  Dan,

  I've marked the important phrase what you're actually doing is moving the CCM of the CBS for the TC/copper connection. Any difference in temperature will directly add to the error.

  However, don't try to save the copper with your approach to 7 + 1, ask IT for another 12 m Ethernetcable guys more and go with 7 * 2 + 1 pair of reserve and make the summary at or near the CBS. IF you need a differntial measument system later, you need to rebuild all connections. (And not just add a new cable for all conical fittings, it is the twisted pair that makes the magic Yes, same vor 1 m!) Remember that you are dealing with µV! And since you want to quick reads without filter a lot of way, do not try to save $10 to about 12 m of cable. Somehow I have the feeling that you try you anyway

• Installation of the USB 2.0 extension cable failure, and I am on Windows 7.

  I recently bought a foot 6 ' Male/female' USB extension cable, and it's USB 2.0.
  I bought it because my headphones would not properly work because of a problem in my computer and I thought that an extension can help to stop this problem.
  So, I try to install, but it never does.
  Does anyone know why there are installation problems?
  Also, Yes, the helmet works if I plug it directly on the computer, but with some errors.

  Hi guy,

  I understand that the USB 2.0 extension cable does not work on your computer.

  1. What is Gets the error message when you connect the headphones to the computer?
  2 have you tried plugging the USB cable into another computer?
  3. have you tried it with different USB ports?
  4. What is the brand and model of the computer and a USB headset?
  5. did you of recent changes to the computer?

  Extension cable does not need a driver, this is just a thread. USB cables come in varying degrees of quality. The length of the cable can also be important, because the voltage of the equipment can be reduced by the resistance of the cable. Some devices specify 6 feet or less while others may work correctly with 12 people or more.

  I would suggest trying the following steps and check if it helps.

  Method 1:

  I suggest to run the hardware and devices Troubleshooter and check if it helps.

  Open the hardware and devices Troubleshooter

  
  http://Windows.Microsoft.com/en-in/Windows7/open-the-hardware-and-devices-Troubleshooter

  Method 2:

  I suggest to open a session on the helmet manufacturer's Web site and install the latest drivers for the headset, if the problem persists.

  You can also check the USB device drivers updated using windows update. See below the help link

  http://Windows.Microsoft.com/en-us/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

  If the edge of the question persists I'll ask allows you to check the chipset driver updates you find on the manufacturer's website. The chipset drivers normally integrate USB controller drivers as well.

• Satellite C70 - A - 16 L - screen resolution problem

  Hello

  I recently had a screen resolution problem with my laptop (C70 - A - 16 L).
  The max screen resolution which is imparted to me is 1366 x 768, whereas before I think he used 1600 x 900.

  I tried the latest drivers, Bios, etc. and have also restored the operating system to a previous backup, as well as a new installation.
  I also tried to roll back to Windows 7 (with proper drivers). They all offer the same problem.

  This new maximum resolution display correctly - as if the LCD does not deal with the timings of 1366 x 768.
  I believe that the Panel is OK and the problem he reports the EDID information properly - to force windows to use the new resolution.

  Is there a download monitor.inf file that can be used to bypass the EDID reported by the Panel?

  Kind regards

  Antwist.

  If the right to display drver is usually installed everything should be OK.

• Microphone C20 length Max extension cable

  Nice day

  I would like to know if it will be possible to extend the standard microphone C20 cable last 15 m...

  Thank you!

  Hey Martin

  We can use the extension for the microphones to C20. Even its listed in the parts and components Guide:

  CTS-QSC20-MIC =

  20 and 7.5 m of performance Mic cable attached

  CAB-MIC20-EXT =

  Extension cable 10 m for CTS-QSC20-MIC, 3.5 mm F 3.5 mm M

  So we can say that you can use the microphone with 2 extension = 37.5 meters, a little more of 90 feet.

  Thank you
