How to connect external trigger PCIe1427
Hi,
We are working with PCIe 1427 frame grabber and a IR camera with Cameralink Standard. Our camera has got asynchronous reset at CC3, so we have given external trigger 2 in NI MAX and successfully able to grab the video. But we need to implement the same using Labview application, so tried to use imaq configure trigger3, imaq trigger drive VI's and unsuccessful in resetting the camera and grabbing video.
We are using IMAQ 4.9 driver and Vision development module with Labview development suite 2013 SP1.
Kindly provide any solutions.
with regards,
Sri
Hi all,
Any suggestion in this regard.

How to connect external trigger PCI-1433
Hi all:
I met the same problem as this old post: https://forums.ni.com/t5/Machine-Vision/How-to-connect-external-trigger-PCIe-1433/m-p/1677560/highli...
however the post did not give solution.
I am having an issue getting the external trigger( from PCI 6259) to work with a cameralink camera, a PCIe-1433 card . The PCI 6259 is connected to BNC 2111, the output trigger signal from CTR0 is connected to the SMB connector on the 1433 card and is providing pulse train at TTL voltages (0-5V). Using the MAX SOFTWARE and under the Acquisition tab I have CC1 set to external 0, however the camera is not receiving this external trigger. The camera is Basler 4096-140km.
I measured the ouiput signal from CTL0, the sigal seems good.
I tried RTSI trigger before, failded. I thought SMB should be more straight forward, seems I was wrong.
Looking forward to reply!

External Camera Trigger(SMB).vi 57 KBBobjojo,
You will actually need to affect the properties of both the camera and the frame grabber to take advantage of this triggering mode. I found a document that contains a good run down of the process to acquire in this mode (linked below). As far as the programming for the acquisition is concerned, the frames will be built at the driver level for the specified frame height. This means that the IMAQ driver will composite the line scans for you, and any simple acquisition (the document shows using the Vision Acquisition Express VI) will be able to pull the image into LabVIEW.

How to connect external trigger PCIe-1433?
I am having an issue getting the external trigger to work using a cameralink camera, a PCIe-1433 card and a signal generator. The signal generator is connected to the SMB connector on the 1433 card and is providing a 20 Hz signal with a 20ms pulse width at TTL voltages (0-4V). From memory, we are using the MAX software and under the Acquisition tab I have CC1 set to external, however the camera is not receiving this external trigger.
I've attached a rough diagram of our setup.
What could my issues be? My thoughts are:
1) Are there other settings in MAX I need to ensure? I know the SMB connector can be an input or an output. How can I make sure this is set to input?
2) My input signal is 0-4V which is TTL, but does the signal need to be 0-5V?
Any thoughts would be greatly appreciated. Thank you.

ExternalTrigger.jpg 29 KBHello tuckturn
Thank you very much for getting in touch with us.
1) In Measurement and Automation Explorer, the default is an input. You would need to use LabVIEW to change the SMB connector to be an output. Can you please show me a screenshot of your camera attributes in Measurement and Automation Explorer.
2) Where does this input signal come from? Do you have a 5V TTL compliant output to test this? Can you please provide me the specification for whatever device is outputting the voltage?
Thanks again.

HT3988 how to connect external keyboard to the garage band if its possible
how to connect external keyboard to the garage band if its possible,
is any body tried ? I have roland e66 keyboard and im trying to
connect with grage band but i dont know thats is possible??You can definitely just connect a mouse and keyboard and then an external monitor and it will work. In the power options in the Windows control panel you will have a choice as to what happens when the lid is closed. Set it to "do nothing" and then you can shut the lid of the laptop and use only the external monitor.

How to connect external sensors to labview?
i want to ask How can i connect external sensors to NI labview for my final year project.? here are my lists of sensors:
a. Temperature sensor (LM35)
b. Humidity sensor (HH10D)
c. Light sensor (LDR)
d. Moisture sensorsimply_me wrote:
I've used the NI's bread board (with DAQ assistant initially) when I was in school. We used it for temp, light, and etc... measurements, the whole system is very straight forward. I would say having the option to simulate signals is a big plus in that. From what you described, I don't think the "slower" rate of data acquisition will disturb you at all. But more information is needed on your sensors and general functional spec.
@ NIquist & RTSLVU, please correct me if I'm misleading/wrong :-)
Is that the ELVIS stuff? Very neat but kind of pricey (unless the school is paying! )
Again, the low-cost USB DAQs from NI or MC are the way to go for the OPs project. I am assuming that he has enough electronics background to make simple signal conditioning circuits for his sensor chips.

How to connect external speakers to Satellite A100-451
Hello,
I have a Satellite A100-451 (UK) running Vista. I want to connect external speakers. There is a 'headphones' jack on the front (3.5mm jack I think), can I connect external speakers here? The speakers are 'PC Line' with their own power supply and also have a 3.5mm jack plug).
Thanks
KKYou need the audio Line-out put and the headphone jack provides this output.
In other words you can use this jack to connect the external speakers -
How to connect external display to iMac
which port do I use to connect external display to my iMac ?
Welcome to Apple Support Communities
Depending on the iMac you have, you have different ports: Mini-DVI, Mini DisplayPort or Thunderbolt. Mini DisplayPort is available in 2009 and newer iMacs, and Thunderbolt is available in the Mid 2011 and Late 2012 iMac.
You have to use one of those ports to connect an external display. You will probably have to look for an adapter, depending on the port the external screen has got -

How to connect external 24'' display to a Satellite A210?
I am using an lcd tv as an external display for my satellite a210, connected with a vga cable. But I cannot just use the external monitor, I can only use both at the same time. Also, the maximum analysis I can get by using them at the same time is 1280x800, because that's the laptop's highest analysis I guess. Are there any drivers I need to download or is it something I can't resolve?
Hi
Generally speaking you can switch between the devices using the FN + F5 key combination.
It should be possible to output the video signal on both devices (notebook & external screen) and only on external screen.
I think you should change the external screen resolution to a lower level
As mentioned above, the 24 supports high pixel rate and I would reduce this to the same like supported by notebook screen.
PS: you can also update the graphic card driver if an newer is available. -
How to connect external hard drive and DV camera
I have just bought a macbook pro with only one firewire 400 port. My question is, what is the best way to connect up an external hard drive and a DV camera so I can import video to Final Cut. Should I be plugging the camera directly into the external hard drive's firewire port and conecting the hard drive to mac via USB or connecting DV to mac via Firewire and then mac to hard drive via USB? Or does it make no difference!
Thanks in advanceIf the drive has two firewire ports, connect the camera to one FW port on the back of the drive and connect the drive to the computer using the other port.
If the drive does not have two firewire ports, you'll need an Expresscard 34 firewire card to create a second firewire bus. The card goes in the slot on the side of the computer. Hook up either the camera or the drive to it.
The cards can be found online for a reasonable sum of money.
Do not use USB.
Good luck.

How to connect external storage devices (flash drive) with it
hello dear. I am using this hp webOS-3.0.5 device for last 8 months. It is really a wonderful device to have. But I have some queries regarding it's usage. First can we attach any usb device(external storage devices (flash drive) with it? Second is there any other way to use internet on it without wi-fi connection? Thanks
Post relates to: HP TouchPad (WiFi)I'm afraid the answer is No to both questions.
External storage can be acheived easily using the free 50GB Box.com account included with each touchpad. This does rely on a good wifi source however, which leads to your other question.
The wifi touchpad needs a wifi signal to go online. Modern cellphones can act as "wifi hotspots" and can translate a cellular data connection to wifi. (I do this with my Pre3 and a free program called "FreeTether", a homebrew app).
