P8253 - Programmable timer

Hello to you all,.

I'm looking for a model of simulation for the Programmable interval timer 8253 (or similar).

I have it in a system for the acquisition of data with which I work.

The point is that I don't need the feature itself. I is not serious if it's the same integrated circuit.

The data acquisition card use this component and I need to simulate its functionality.

If someone has something to help me?

I would appreciate any support.

Thanks in advance.

Patrick,

based on the software I could see what mode operations were used and the good news is that the software uses the same simple mode for all counters.

I ended up taking simple down counters for use with PLL and it seems to work.

Thank you for your help.

  • need help on modbus RTU: do not know the meaning of the other output registers

    Hi all

    I use LV 8.5, a programmer time & 1st novice LV to post msg in discussion, so please let me know if I missed something important.

    In any case, I'm 2 power meter data acquisition (1st is CPM-50 model, 2nd is MWH - 10, the two brand ADTEK). the Protocol of these devices are modbus RTU. I have two targets to:

    1 acquire data using RS - 485 (portable <-->meters of power)

    2. acquire data using ethernet (laptop <-->converter series/ethernet <-->meters of power)

    now I'm in the 1st part, I use the local brand USB-RS485 converter & I think that there is no problem in the port itself (past the loopback test). I create a program using LV samples Mo using w / these port settings: 9600, 8, N-1 as databit baud, parity, stop bit respectively (the same data format of the device: see page 17/42 of the manual). I use the query.vi series of MB that I customized to eliminate the error timeout 6101 (see attached photo).

    Problem: I can read the right data into the output register , but is located in the 5th element of the 1 d array. In the peak of the attached example, I'm currently reading the baudrate of the device (see manual pg 26/42: address 0102 h = 258 d). so I read the 9600 w/c is correct. I also had the correct readings of other addresses of parameter which is also located in the 5th element of the 1 d array. Note: I never tried to read data from power because the meters are not yet installed in the cabinets of power (maybe installed nextweek leave)

    Question:

    1. What is the significance of the first four output records in my table 1 d of output?

    2. why I got 5 output registers eventhough I'm asking only 1 quantity?

    3 read the correct data in the 5th element normal?

    I want to just be deleted in the data I read before jumping in part 2 (connection via ethernet). If I forgot some valuable information, let me know. Thanks in advance!

    Kind regards

    If an error occurs during the start cannot be shown on the screen, the computer may emit a beep code that identifies the problem. The beep code is a combination of sounds: for example, one beep, followed by a second, and a burst of three beeps (code 1-1-3) means that the computer could not read the data in NVRAM memory.

  • Is it possible for my daughter maintain its programme of Photos on its 3 t Time Capsule? It happened to wide to keep on his Mac laptop.

    My daughter is running out of room on his Mac laptop to store his photos. She still uses iPhotos, so I have him asked to look at pictures. However, we also tried dragging his case iPhotos to 3t Time Capsule that we arrived to appear on his desk. It would not copy. So, first of all it allows Photos on his Time Capsule to use with his iPhone to store his photos? I'm guessing not because I don't think the Time Capsule works on Mac OS X required to run the Photos. I do not know because I have never used a Time Capsule.

    Second, if it works, how can I help him, by telephone, to do.

    Thank you

    Tell him to get an external drive, as Mac OS Extended format if it is pre-formatted not in this way, the library put there, launch iPhoto or pictures with the key Option key, and then choose this library. Once this is done, open the Time Machine system preferences pane, click Options, and remove the external drive from the exclusion list.

    The working copy of the library should not be stored in a Time Capsule; only its backups should be there.

    Make sure your TC has no ID configuration inside apple. There is a bug at the moment that Apple introduced recently.

    I highly recommend a clean installation with short names etc.

    Universal factory reset

    Turning off the TC... That is, remove the power supply cord or the power at the wall outlet, wait 10 seconds... Hold the reset button... be nice... Turn on always even now in reset... and keep holding in for another 10 seconds. You may need assistance because it is difficult to hold in reset and power on. It will show the success quickly flashing led front. Release reset... and wait a few minutes for the TC to reset and return with the factory settings. If the front LED flashes quickly you missed and simply try again. The reset is quite fragile in these... Press the key while it is just click away and not more... I've seen people bend lever or even break. I use a toothpick as a tool.

    NB. None of your files on the hard drive of the TC are removed... This simply clears the settings of the router of the TC.

    The installer the TC.

    Then redo the configuration of the computer that you want to use for TM using Airport utility.

    1. the use of very short names... NO APPLE RECOMMENDED names. Without the space and pure alphanumeric characters.

    for example TCgen5 for the base station and the name of the TCwifi wireless.

    If the wireless is still an issue defined wireless names like TC24ghz and assigned the 5 GHz other name... for example. TC5ghz

    2. use all passwords also consistent with 1. but maybe a little longer. IE 8 and 20 characters of mixed cases and numbers... no alphanumeric non-caracteres.

    ** 3. If the TC is router, you can ignore this point. It is only a problem when the TC is bridged.

    If ensure that the TC is always the same IP address... you will need to do this on the main router using a dhcp reservation... or a bit more complex setup by using the static IP address in the TC.

    Ignore this point if you don't understand it... after the return if you drop questions.

    4. be sure that IPv6 is set correctly in the computer. IE link-local only for ethernet or wireless depending on whether you are using. Car is not good enough.

  • AirPort Extreme &amp; Electrical Outlet Timer

    Hello

    I have the newest AirPort Extreme (http://www.apple.com/shop/product/ME918LL/A/airport-extreme?fnode=7f) and I recently moved to my room in my basement to the second guest room floor providing a 2.4 GHz and the private network wifi 5 GHz (two separate networks) to my house.

    I read on the sleep disorders causing wifi signals and how it can cause generally negative effects be exposed continuously to EMF signals.

    What I'm wondering is it would be harmful to my AirPort Extreme to put it on a timer plug (ELS https://www.amazon.com/Enover-Programmable-Digital-3-prong-Appliances/dp/B0191ZG/ref = sr_1_2? ie = UTF8 & qid = 1469557186 & SR...) so that I can program it to turn off the power to the router around 11:30 and turn it on again around 06:00; eliminating privileged exposure to EMF for me and potential customers during the hours of sleep?

    I understand that many of us may be divided or not there is any real effect signals wifi on sleep/general health-it's NOT what I'm asking.

    Everything interests me is whether or not it would be damaging for the router AirPort Extreme to cut the power at night via a programmer power socket and then to restore it again in the morning on a daily basis.  It will shorten the life expectancy of my router?  This will degrade the quality of my wifi over time signal?  Thank you in advance for the answers!

    The debate about so consistently turn a device and off is better or worse that just leaving all the time has happened since household electronic appliances were introduced.

    One school of thought argues that constant power down and the cycle puts more emphasis on the electronics inside that just letting the device at any time and this extra stress can lead to a shorter life for the product.

    Another school says it does not matter as the power on and off the power of everyday, or has left the whole time that the life expectancy of the product is concerned.

    Make your choice... good arguments can be advanced for or against powering a device works every day. Call him a link if you want, or return a coin.

    Personally, I lean toward the school "let him", if not because the internet connection and network is likely to be more reliable in this way. In other words, if you turn off the airport at night and power it back up the next day, the airport will lose its Internet connection and network and be forced to establish a new connection when it is consumed in back to the top, with more chance of something going wrong.

    Although I leave the airport on almost all the time, if I'll be gone for a few days or more, then I usually turn off the airport if I remember to do it before my departure... to save a few pennies on the electricity bill.

    I only have one gripe, and it's commissioning at least 3-4 minutes of time.
    Am sure that this is the amount of the programms (bloat ware) which are loaded at the beginning.
    Any suggestions or direct contact with Toshiba to know what stop to load would be great.

    Hello

    Hmm. I think that you can solve this problem very easily;

    (1) I recommend you begin with cleaning of the operating system. Use a tool called CCleaner.
    It s freeware and you can clean the registry.

    (2) as more option, I recommend turning off some background process.
    You can disable it's msconfig (in run type msconfig). You will find the Startup tab.
    Here, you can deselect some unnecessary applications that should not be started at the beginning.

    I think that should help make the QuickStart.
