• Trouble connecting Netgear XS748T to Ubiquiti UniFi US-48-750W via Port SFP +.

  We bought a new switch Netgear XS748T and try connecting to our existing network which consists of several switches of Ubiquiti UniFi US-48-750W, and we try to connect using the SFP + 10 GB ports on the two switches. We have a Direct Link SFP + SFP + DAC, passive, 1 m, cable AWG30, we bought at Amazon / 10Gtek and when we try to use this cable between the Ubiquiti switch and the Netgear we get no link activity.

  However if we use the same cable between two of Ubiquiti switches it lights immediately and works very well, the same is true if we use the same SFP + cable between the switch Netgear XS748T and a XS728T that we must also. Its almost as if the switches detect the same manufacturer at the other end and right link up but when its manufacturer another pass on the other end, it does nothing.

  It is very aggravating, and Im going to be obliged to return the new Netgear switches. Can someone make a suggestion or confirm if they should or may not work? Everything simply connecting switches together using a cable of copper works very well but since our current switches don't support 1 GB via copper it provides not enough bandwidth for our use so we really need the port SFP + 10 GB to give us the uplink.

  Here is a link to the modules SFP + cable, we bought:

  https://www.Amazon.com/DP/B01LSGGUOY/ref=twister_B01M0ER4M0?_encoding=UTF8&PSC=1

  It seems that I solved the problem myself. I bought a set of:
  10Gtek for Cisco SFP - 10 G - LR, 10 Gb/s Transceiver SFP + module 1310nm 10km

  And the LR version worked instantly. I honestly don't know what's the difference between a SFP + SR module and a module LR SFP +, but for some reason any LR module has allowed these two switches to connect.

  Here are links to the modules and the cable used in case anyone needs a solution to this:

• PowerConnect 2824 Ports SFP does not

  We bought a new switch 2824 with a corresponding to SFP module replace old 2724 PowerConnect and SFP module.

  After the configuration of the switch and installing it, we were able to get a connection on our uplinked to fiber.
  SFP light illuminates and flashes from time to time, and the switch detects correctly module SFP is inserted and that the fiber is connected.  We can see the insertion of the SFP is detected and the switch for change of fiber mode by looking at the output of the console, and the web administration port status page lists the port as "ComboF" when the SFP is inserted and the fiber is connected.

  However, the switch always indicates that the port State is down.  (The port is not administratively disabled.)

  The old switch works very well with the old SFP module.  The new switch does not work with the old or the new module SFP.  We tried two combo SFP ports.  We also checked that the fiber itself is fine. We cannot get the new switch to display the drop-down list port status that up when you use the SFP. We tried to completely reset the new switch by removing the configuration file via the boot over the serial connection menu and re-run the initial configuration wizard, but the port still won't go up.

  Any ideas?

  After a few tests yesterday, we determined that part of auto-negotiation must be disabled for switch work with our copper and fiber Media converters.

  The 2724 works very well with our media converters, with auto-negotiation enabled.

  The 2824 works very well with auto-negotiation enabled when it is connected to an another SFP transceiver in building switch.

  But when we introduce the Media Converter in the path, the 2824 will bring only the link up if you disable auto-negotiation.

  So far, everything looks good.

• Cisco ASR1002 - 5 G/K9 - 8-port SFP MGBSX1

  Hi guys,.

  I am trying to improve the telephone network switched on a customer site. My goal is to install a router in order to split the telephone dial in 7 broadcast domains.

  So far, they have used a very old Catalyst 4000 switch as main switch to interconnect the 7 offices and many 3500 series access switches.

  I found the ASR1002 Router - 5 G/K9 which seems to me a good deal. At a first sight, it seems just need to buy a plug-in that supports additional SFP 4 and nothing more. The connector SFP, I need is MGBSX1.

  Could be he you guys please let me know if I can be wrong and if you know better solutions? The budget is limited to 10 M $ to $12 K.

  Thank you very much

  Hi Darren,
  Thanks for your answer. I don't need any NAT or routing protocol because all I have to connect is in terms of routers are just that device and the Telco Router. Do you already know the code of the module I have to add on the 3750X?
  Dario
  

  You don't need to add * any * modules to 3750 X - model I quoted has 12 ports SFP - you just plug the appropriate FPS.

  If your links are copper (I.E. not long range), then you can even cheaper do - buy a WS-C3750X-24 t - S - 24 copper gigabit ports - much to segment your network based on.

  If you need uplinks of fiber, then the first switch on WS - C3750X - 12 s-S - will give you 12 ports SFP based - but without knowing what kind (and distance) of fibre you need / have, I won't recommend fiber SFP.

  See you soon.

• Error in the capture of several channels using pre-trigger

  I have problems of acquiring data with pre-trigger samples during the capture of several channels, using hardware NOR-PXI-6071E and Analog Input VIs in Labview (inheritance OR-DAQ).

  My goal is to trigger a signal, while capturing another. Unfortunately, I can't use the PFI0 for external triggering, as our cables/material have already been built, so I have to use an analog input as the trigger channel. I understand that to do this I must capture the two strings and the string I want to trigger outside must be the first string in the list.

  If I trigger and capture on the same channel (I tried 1-4) then it works very well, regardless of the number of samples before relaxation together. If I capture more than one channel (the channel of the relaxation to a first), with no pre-trigger samples, then trigger and capture both work very well. However, if I do the same thing with pre-trigger > 0 sample I get the following error:

  Error-10621 to AI control. Possible reasons:
  NOR-DAQ LV: The specified trigger signal cannot be assigned to the resource for the trigger.

  I don't have to such limitation explained in the user manual, and the forum search, I found a few other people who have had the same problem but they had no solutions. Any ideas?

  Hi Jackson,

  Unfortunately, this is a hardware limitation when you reference analog trigger via one of the lines to HAVE.

  Please see this knowledge base. Particularly the second paragraph says

  The error-10621 appears immediately when the VI running if you try to assign scans of relaxation before while scanning multiple channels and using one of the entries as your trigger channel.

  Details are explained in the third paragraph:

  Because all the entries are multiplexed before being sent for analog triggering circuit, it is possible that the trigger on the trigger channel conditions might miss while the device is multiplexing by another channel. In this case, the trigger will not be detected.

  It is explained in the E-Series user manual page 10-3.  Specifically the second paragraph of the section entitled "Analog Input Channel".

• Numberic channel using Dict.Add text conversion

  I have several channels that have a text value for them and I used a Dict.add function to change the values of a number so it can be traced linearly.  However, I had to create a separate for each channel in the set data function.  I want to generalize it more so it will come out and watch an all channels and compare the values of the dictionary already created.  I have attached a sample form of how I currently do not change and I played with a new form called TxtToNum.vbs which is more widespread.  I have 6 dictionary that I use in total as well so who plays in the task.   I do a lot of work of script and could really use it little assistance.

• Interference between channels using a block of cFP-TC-120, CB-3 connection

  Using a CB-3 with a cFP-TC-120 module connection block for read sensors millivolt. The sensors are pressure with an excitation of 10V sensor. Millivolt signal varies 8mv to-70mv. All have 8 differential channels wired in two of these modules sitting in slots 3 and 4, a slot 4 back on the plain. There is also the 24V in the electrical box used by two modules to relay PSC - 421 driving valves that open, leads at room temperature or in separate the empty rooms they are in slots 1 and 2. Do to the cFP-TC-120 the same and each is affected in the same way, more interference is not only between the same module 120 channels, but also between the modules! If a sensor is vacuum where the millivolt is around 7 mV reading is stable through the following conditional changes. "If a sensor is emptied at room temperature, say channel 6 and channel one is already at room temperature its reading can change by 0.25mv be affected by the evacuation of other channels. This worsens proportional number of channels is ejected by up to 0.5 mV for all other channels that are evacuated. This module is differential and each channel and the module are isolated we don't understand where or how this interference takes place. Help!

  Ben,

  We have done some trouble shooting and isolated in millivolts sensor signal of the NOR. We found that voltage was real and electronics is not the field point. The system runs on 24V except for sensors that have an excitation of 12v. We found that the Commons between these continuous tensions were just that, each have been shared. We have separated the Commons and vola! Perfection.

• Need help to set up an acquisition of two channels using NI5154

  Hello experts NOR:

  I'm setting up a scanner high speed data acquisition NI5154. I have two data channels need to be measured. In fact only the waveforms in the channel 1 must be recorded and channel 0 is used for counting digital pulses.

  My goal is like this: once started, the digitizer should count the digital pulses in channel 0 for some time until a start trigger happened in the channel PFI_0. After receipt of the beginning in the channel PFI_0 relaxation the digitizer should switch to channel 1 and start captured signals and save them to the disc.  After a well-defined time, stop digitier the acquisition in channel 1 and then switch to channel 0 and repeat as cycles.

  my questions are: what the best way to count the Digital pulse channel 0 ? The only way I know is the source of reference on channel 0 command and then get the number of "Done Records" from the property node.  After the acquisition of the digitizer will be waiting for the trigger to start in the channel PFI_0, no pulse in the channel 0 will be counted. If I let the impulses in channel 0 not counted in the first cycle, at the end of each cycle how can I switch from channel 1 channel 0 and saitch return after receiving the trigger from the beginning? It seems that I have to configure the trigger repeatly system.

  
  

• How to read voltage on several channels using the 6255\SCB-68

• How to replace the units of a channel using scripts % 3F

  Hello

  I have a few questions about the manipulation of the channel property 'unit' by scripts.

  Case 1: If the unit in the chain is not specified in the properties, what command should be used to add the inside unit?

  Case 2: When I create using the string ' Call.Root.ChannelGroups (1). Channels.Add ("name", DataTypeFloat64, 1)', empty space of unity being, what other command can be used which was available to the units to the breast?

  Case 3: Consider that I have channel (channel A) with the already defined unit (x), how can I replace the unit with another (y)? (Units of x and there belong to different physical quantities, so the ChnUnitConvert)

  Pls let me know if you nee details on the same.

  Kind regards

  Fazil Shah.

  Hi Fazil,

  The key word for SCRIPT DIAdem units is "unit_string". If you open the SCRIPT and open the channel property list you can select the property unit and drag & drop it in the SCRIPT Editor. This creates the code of script for the property.

  Case 1
  You have the options of towing: a quallified assignment complete or a channel object variable (if you have more settings for the channel of the second alternative is better)

  Data.Root.ChannelGroups (1). Channels ("mychannel"). Properties ("unit_string"). Value = "MyUnit.

  or

  Dim oChn
  Set oChn = Data.Root.ChannelGroups (x). Channels ("mychannel")
  oChn.Properties ("unit_string"). Value = "MyUnit.

  case 2
  You must add the unit after the creation of the channel

  Set oChn = Data.Root.ChannelGroups (x). Channels.Add ("MyChannel", DataTypeChnFloat64)
  oChn.Properties ("unit_string"). Value = "MyUnit.

  case 3
  It's the same as case 1 or if you do not want to use an already existing channel device, it can look like this

  oChnA.Properties ("unit_string"). Value = oChnB.Properties ("unit_string"). Value

  I hope that answers your questions

• Imaging multi channels using the acquisition card OR

  We have a 1408 IMAQ being controlled by LabVIEW 8.0.

  We want to install multi-channel of imagery. All the channels work individually. However, when I was trying to show two channels simultaneously, single channel works and I got the following error message:

  Error 1074397150 has occurred to IMAQ enter Setup.vi

  Possible reasons:

  NOR-IMAQ: A timeout error occurred while you wait for the specified event. If you expect a picture, make sure all the video data is acquired during the period. If you wait for a signal, check that the assertion of signal occurs within the period.

  Sometimes I get a different error message asking me to assign different buffers to both channels. I understand that IMAQ 1408 has only analog digital (ADC) converter to digitize the incoming video. It may acquire up to four different cameras, but only of a camera at a time.

  I don't mind do frame rate in half. I think to show only one channel at a time and do the two channels alternantly. But I need to know how config routes to get there.

  I've attached an example that should work.  I could not test it because I don't have the equipment, so it might need some settings.  I would test it with one channel by setting the channel # 1.  Once it works, define channels # 2.  I set the display to use snapshot mode so the same image can be used for all screens.

  The only reason that I can think of that would make multi-channel acquisition fail when single channel works is the lack of synchronization between signals.  The start of frame signal must be the same for all channels.

• Windows Media Center will not scan digital channels using a dual tuner (analog/digital)

  I have an AverMedia Volar Max tuner which is analog and digital double Windows 7 Professional
  Media Library 'sees' the tuner as an analog tuner and properly identifies all the analog channels, that I see on TV.
  However, none of the digital channels are detected. I have not found a way to "force" a search using QAM256 or any other research of digital formats.   Using the tuner, cable and connections the same BUT with a linux sotware (mythtv) all digital channels have been identified.
  Is the problem because its analog and digital modes? How can I force Media Center to see the digital capacity of the tuner?

  Might have been a better place to look for information on the AverMedia Max Volar tuner AverMedia USA site.

  If you had looked here to find the latest drivers or to read support information, you would have found:
