• What is the difference between the external SCSI cables and cables data acquisition

  Hi all, I would like to make a simple extension using an external SCSI cable and a NOR 184749/SH 6868. In other words, it would be: female HD68 bolt of the cable ends OR coupled to an external SCSI HD 68 male with a VHDCI 68 male cable. What are the differences between the external SCSI cables and cables as the (M) 6868EP of the CHS data acquisition. Other than the sex of the end of HD68 is usually on one. How is the posting hit buy using an external SCSI cable for an extension to tell a BNC-2090?

  Yes, I realize that NEITHER wants us to buy their cable, but in these economic times difficult, to do use all available resources, so I have to try,.

  Thank you

  Hello

  As long as you have compatible connectors, SCSI cables will work DAQ of basic functions.  They have the advantage of NO cables is that we can meet our DAQ hardware.  So, we can create pairs twisted differential pairs to HAVE, using the ground for shielding terminals and generally specialize the cable to minimize noise and crosstalk.  Because the SCSI cables are not specialized, you are likely to see the most noise and, if you go the sampling rates more Rapids, crosstalk.  If you are in a laboratory or factory with a good amount of noise EMF that your readings are not quite as clean, or if you have fluorescent lights you might see 60 Hz noise you might not see otherwise.

  If you want more details on the specifications of the SH68-68-EPM cable, I recommend these two articles.  The first example of the twisted pair and the principles of the SH cable shielding and the second gives the most precise specifications that you can compare with when looking for a SCSI cable.

  Yes. You should not lose any data, but always have a backup. In this case, you have your internal drive as a backup.

• Can I change the location of the library of Lightroom and default data files?

  

  Marc Mandelbaum , 15 November 2014 06:02

  Hello

  I am running Lightroom 5 on a macbook pro 17 "equipped for one SSD 240 GB and a hard drive internal 1 TB extra.  I have lots of software installed, including a large part of the following relevant Adobe and when all is said and done, I don't have much room for manoeuvre.

  I just imported less than 20% of my photos, about 90 GB, in Lightroom, and the "Lightroom 5 catalog Previews.lrdata" file is about 1/10th of that to 9 GB.  That doesn't seem like much in the overall scheme of things, I know, but which leaves my hard disk space available to a mere 14 GB, which is not good at all.

  My question is this: I looked hard and can't seem to find a way of change my Lightroom catalog files default location?  I would like to change this over the other internal disk where I have a lot of space.  I understand that I am able to move the library once it is compiled, but simply, I don't have enough space to import my library on the main (240 GB SSD) drive to then move it.

  Thank you for your help.

  Marc

  Lightroom will create these files the first time, it opens. And he put them in the default location. Let Lightroom it's thing. Then, before doing all the work at all in Lightroom, close Lightroom and move the folder that contains all the files whenever you want. Double-click the catalog (.lrcat) to start Lightroom. The default preference for the catalog is to open one last used. So now, the catalog in this new location will be one that will open.

• How to remove the author's name and/or date of blogsite summary

  Hello

  Can someone help me please find where and how to withdraw the name of the author of the summary blogsite?

  I don't want any author's name listed, just the title linked blog and the date of publication.

  Or, is it possible to have the related title, with 50 words of the displayed article, but no name of author or creation date?

  I thank very you much in advance!

  I figured out how to remove the CSS author (.blogsitesumary duration-date {display: none}, but any attempt to change via CSS does not work.)

  For example, I can't create more space between the title and the date, or list items.

  Also, I would still add the first words of the post.

• can I use instead of conditioning of analogue output signals data acquisition to provide voltage outputs analog?

  Hello guys,.

  I have a general question regarding the units of packaging such as the USB-9263 analog output signal. If I can use it instead of data acquisition to provide an analog voltage output?

  Thank you

  ELA

  Yes, the 9263 can provide 4 output channels analog voltage (+/-10 v range) with up to 1mA of current drive. Looks like: it refers to the short circuit of conditioning of signals and some protection against overvoltage. Link below is the User Guide:

• Where are the guidelines on how to interface custom for LabVIEW data acquisition equipment?

  I have a need to do some very specialized data acquisition that may require special hardware for the building. I would still use LabVIEW as the front end and maybe even wear parts of the interface of the final product. However, I can't find the documentation. Where is that is kept? I've seen references to a number of generic protocols, no links back to the details, which may be appropriate. The data are a band high bandwidth, but bursty with sampling frequency up to 40 MHz and events that lasts about 100 milliseconds. Can anyone recommend various methods would be most suitable for this application?

• The palette of colors and LabVIEW RT on cRIO

  Hello

  I have problem with the help of the color scheme for Sound and Vibration toolkit in the VI real cRIO running on the system at the time. When I try to drag and drop control of the color palette in the front that I get the icon: http://screenshooter.net/2243673/ervvuqk . Is it possible to use this control on the RT system, or should I do the analysis of the order in a different way? I use LV 2011 (with all updates), maybe that's the problem? I can put the paddle in normal VI under Windows without problem.

  Hello.

  Version of LV, you use, is not reason why you can not use this control on your VI. Main reason why you can not use this control you can see if you click the arrow broken on your VI.

  If you do this, you can see explanation: "'Colormap' XControl: XControl Colormap not supported for the current target".

  Therefore, the RT target that you use does not support this function. It's resonable because usually we need for the presentation of data on the host Party, and not on the RT of the code part.

  I hope this answer will help you.

• Fragmentation of the distribution of system and database data

  Hi all
  
  I'm working on a scenario (University), with the fragmentation of a central database. A company has regional offices, i.e. (England, Wales, Scotland) and each regional office has different combinations of areas of activities. They currently have a central database in their seat and my task is to "design a data distribution system. Regime that means something like the horizontal fragmentation / portrait? Also can someone point me to a specific example of the Oracle of creating a fragmented table? I tried to search online and found the keyword ' partition by ", but not much with the exception of database that links - but I think that it is more concerned with the mark than to actually create the fragments.
  
  Thank you very much for your time

  >
  I would like to create a Db (or data access system) for each region that contains the data for this region - only, for example in Wales has that one sector of activity must therefore only the entered information and used for staff in this area. Instead of completely replicating the entire DB in each regional office, I want to create the smallest region specific "fragments" of the central office DB.

  Regions should combine once a month for pay, etc., but the idea is to distribute the data locally. My task is to find the best solution for the scenario, put in balance the advantages and disadvantages
  >
  The simplest solution is what I suggested in my first answer.

  Use the central DB. Partition of the table as your sample; by region. RLS (row-level security) allows you to restrict the regions to their own data.

  Only a single "Central" table has ALL data regions; It is only in the partitions.

  The only real issue is that the regions will have access as a remote central DB. This isn't really a problem in this day and age. The largest companies have data centers and local regions or offices do not have their own DB.

  In my humble OPINION the replication should be AVOIDED unless it is absolutely necessary.

• Help the query to list all the days between MIN and MAX date in a table

  Sorry, this may have already responded earlier, but I really struggled to find a previous response with the new provision of the RTO.

  In a DB 11 g, I date MIN and MAX in a table:

  {code}

  SELECT MIN (process_date) start_date, MAX (process_date) end_date FROM my_table;

  {code}

  I would get every day between these 2 dates. I mean even is there is no record in the table for a date.

  Is this possible?
