Buysing external antenna is required for AIR-AP1230A & B?

I just went through the check tool configuration for a Cisco Aironet AP1230A-A-K9 and then for an AP1230B-A-K9. Two checked the config like OK, but had a warning on the antennas of wireless products. I hope that this means that an antenna is optional, but if I buy a dish, the only supported are those listed here:

http://www.Cisco.com/warp/customer/779/smbiz/wireless/approvals.html

Is that correct or is buying an external antenna for both mandatory for them to be operational?

Thank you!

Take a look at this link: http://www.cisco.com/warp/public/cc/pd/witc/ao1200ap/prodlit/2356_pp.htm

  • AIR-Antenna compatibility with ap AIR-CAP1602E ANT5160V-R

    HI, I need 2 external antenna 5 GHz for AIR-CAP1602E.

    In the Cisco documentation, I have not found that "this antenna is designed to be used with Cisco Aironet access points and bridges but can be used with any device radio of Cisco Aironet 5 GHz using a reverse polarity (RP - TNC) connector."

    And in stores I found 'designed for Aironet 1100, 1130AG, 1250 modular Unified Access Point Platform, 1252AG, 1252AG Point of independent access, Unified Access Point 1252AG, 1252, 1252G Unified Access Point, 1310 Outdoor Bridge/Access Point'

  • Where is it save to save a photo library? Requirements for the external hard drive

    Apple support documents have been somewhat vague about the requirements for a player welcome photo library.

    It is not yet clear if Photos can run a file system, is not HFS +: this restriction is mentioned only for the system of libraries of Photos, which syncs with iCloud (https://help.apple.com/photos/mac/1.0/?lang=en#/pht211de786)

    By default, your system library is stored in the folder of images on your Mac, but you can move it to another location on your Mac, or store it on an external storage device. However, to use iCloud services, the external storage device must be formatted using the format Mac OS extended (journaled), also known as HFS +.

    But it is experiences during the migration of libraries, that Photos cannot migrate libraries iPhoto or Aperture libraries to a photo library, if is not filesystem HFS +.  It will try to create the library migrated on the system drive instead (probably because he can't create links hard disk) and generally not running out of storage.

    Apple less did today, confirmed that he is not sure store of the photo library in a synchronized cloud storage, see: update to iPhoto to Photos for OS X - Apple support

    If you store your photo library in a place that is part of a Cloud Computing service (for example, Dropbox, box or Google Drive), your library might be damaged by the synchronization process. So, you might lose photos.

    To see your photos on all your devices, you can use iCloud photo library. To back up your library, you can use Time Machine.

    I still have not found supporting documentation, that clearly indicates if a library of Photos can be stored on a NAS. If it cannot be used as a library of Photos of system.  For the opening of libraries or libraries of iPhoto, the recommendation of Apple was clear: use locally mounted volumes extended, Mac OS X for your Aperture library

    Does anyone found a similar document for the Photos?

    Is it possible to store original files referenced on iCloud by car or in a box?

  • Where can I find external antennas for the extreme UFO from the airport

    Where can I find an external antenna for my extreme model of the A1034 (UFO) airport?

    You can check with the support of Quickertek , since they used to provide an option for the A1034 AirPort Extreme antenna upgrade. Maybe they might have even a few shares left, even if the product is not on their current site.

    http://www.QuickerTek.com/

    If you have a Radio Shack or Fry near your House, take the AirPort Extreme to see if you can find an antenna with a connector that will come into contact with the connector on the AirPort Extreme. Any small, simple antenna will do, the trick is to find one with a connector that fits the AirPort Extreme.

  • Need for an external antenna for desktop - what to buy

    My mom just got a new HP desktop.  She lives next door to my sister who has/wireless router.  In the configuration of his computer, the photo shows an external antenna cable that plugs in the back of the tower.  However, in the store, they have a variety of USB things that sound like they do the same work.  His house is about 500 feet of my sisters.  What is the best, most economical solution.  Be precise because clearly I'm not tech savvy.

    I think you're at the limit of the standard Wi - Fi if you want to connect to a PC that is inside a House to a wireless router that is in another House of 500 feet away.

    If there is a line-of-view between the two houses, then you can consider adding a pair of outdoor access points.  I have a set of an older version of these products, and they work very well for me:

  • The Pavilion Elite HPE475 need an external antenna to a wireless connection?

    I just bought this machine and have had problems with a poor quality since the wireless signal. HP technical team came up with all sorts of different explanations, and I even had to send for the "repair" because one of them think that the wireless card was defective. The last time it's because he needs an antenna.

    Can someone confirm if this machine wireless card requires an antenna to be connected to the two screws Golden at the back of the computer? What is the answer, or just another diversion?

    I was not sent an antenna with the computer, it may be a mistake the part of HP. I can connect to the internet, but usually get that two bars on the signal, while my old computer has always had five bars, as do other computers on the network. The connection keeps dropping out and is extremely slow to load at times.

    Any help would be appreciated.

    Hello

    I suggest that you take a look at what came in the box.

    The low-profile wireless network card should have with an antenna and two cables with connectors from red and blue to differentiate the connection to the wireless card.

    The service center may be assuming that you already know that... All the wireless cards that come with desktop computers have a connected external antenna with cable to the wireless card.

    This image is an example. Some cards equipped with antennas that screw directly on the gold screws. Most 802.11 b/g/n card look like this.

    Please report anything that is on the label with bar code on the back of your PC, except the serial number. The HPE475 is not a complete description of a PC.

  • Card required for control special measures

    Hello!

    We have some NOR-DAQ cards (PCI-6221, 6251 and 6036E) but none of them seem to be capable of the following measure.

    There is a digital pulse train that must be received (practically with a meter). To measure the VOLTAGE to a channel of AI when a pulse is received. The frequency of the pulses can be 1 KHz, therefore generating events at each pulse for the PC is not viable. He must also know where the pulse OCCURRED (something as the card should have its own clock and should be able to put next to the measured voltage value).

    In addition, the map should give a sign of output (pulse change or line) of 1. the number of pulses reached a given amount or 2. the voltage is lower or exceeds a value given to a channel to HAVE. If an automatic output is not available at least we have an event to the PC.

    Will there be any card to fix this? In fact the card must have at least two meters since we have two trains of digital pulses, but only is active to a degree. Thank you very much for your suggestions!

    Could you clarify it please ", we have two trains of digital pulses, but alone is.
    Active to a degree.  You check in for a number of pulses on several lines?  You have more than one channel of Analog Input?

    Without taking into account the requirement for the 2nd train of digital pulses for the moment, to my understanding of the application the 6251 could do you need:

    1. the signal of AI must be connected to the 6251, since it is the only one of the three that supports analog trigger.

    You need to configure an analog reference trigger to allow comparison shipped.  You can use the line to HAVE it if you are sampling just one channel (or an APFI line if you're sampling from multiple channels).  Export event of analog comparison will tell you when the signal is outside a certain threshold (the graph presents 'Entering the window' but you can select "Exit" instead):

    2. connect the Digital pulse train to one of the PFI lines on the 6251.  It will be the sample for your task clock to HAVE.

    4. use the same PFI line as a source for a meter (pulse) output task.  Set the initial delay so that when the desired number of pulses have been counted you will produce a pulse on the output of the counter.

    5. you now have a line telling you what N pulses have been reached (from step 4) and a line telling you where I is outside a window (in step 1).

    6. If you want to timestamp pulses using the edge of the Office counter, you must use the counter 2nd as a county of edge stamped with the external pulse as your sample clock signal.  This will give you a very precise timestamp of your external impulses (compared to the beginning of the task).

    If you need for impulses of timestamp on multiple lines, you can look in the task configuration of change detection of DI on the 6251 and using change detection event as the sample for the task of counter clock.  You must implement logic in SW to determine which line has generated the actual event.

    You have also 4 other counters to play with on your other DAQ hardware two, so depending on what you want to do, you should have a little flexibility.
