No signal from ATV 2

Hi
My apple tv 2 has been working fine for some time now, but as of last night when i turned off the ATV i hasn't been able to display a picture.
The ATV shows the Apple logo as ussual when i turn it on, but afterwards the screen writes "no signal".
I hope someone is able to help me with the problem?

Did you try routing the HDMI cable to a different port on your Samsung? That said, I have both an ATV1 and an ATV2 connected to my Samsung and have never had a failure to "see" either ATV.
Also, I don't buy into the "deluxe" HDMI cable theory as I have several $5 HDMI cables running to different TVs in the house and I've never had one not work. That said, the post above yours does say a "deluxe" HDMI cable did make a difference.
Perhaps you just got a bad ATV2. You should consider taking it back for an exchange.

Wireless signal from iMac to TV?

I have a new 20" iMac G5 isight on the way and have a question. Has anyone tried to hook up the iMac (or other mac) wireless to your TV. There is products like this www.amazon.co.uk/exec/obidos/ASIN/B000068TYR
ref=erra_acc_dp1/026-6032989-4654855 that will send a signal from your antenna to your TV wirelessly. I thought mabye in combination with a TV tuner like EZ there would be a way to get the signal from the mac to the TV. That way I dont have to drill a cabel-hole in my livingroom floor down to my office to enjoy FrontRow on my TV. Or is there any other solutions/suggestions?
(And i dont think there will be an Airport Express A/V launched next week... though I wish!)

You should be able to connect your ATV directly to your iMac using Internet sharing, but you can't use the same NIC that the iMac is using for its connection. If your iMac is connected to your router by wi-fi, you can share the Ethernet port with the ATV. If your iMac is connected to your router by Ethernet cable, you can share your iMac's AirPort with the ATV.

No 5.1 audio from ATV

i,ve seen this discussed everywhere but cannot find a solution. Ihave an ATV2 hooked to my yamaha receiver with toslink and an ATV3 hooked to a seperate yamaha receiver in my basement hooked via HDMI. I can't stream any 5.1 audio through the ATV. The receivers indicate the incoming audio signals as 2 channel only. I have tried previews from ATV Movies with the DD symbol but only get 2 channel. I have a copy of Jump Street 21 imported in itunes with 5.1 AAC audio track and still get only 2 channel. I checked that movie with Macmedia and it indicates only 1 audio track and 6 channels. If I use my Macbook pro with thunderbolt to HDMI i am able to get 6 channel audio from the same movie. I have the Dolby digital set to on on my ATV. Please help I am really frustrated by this.

Getting Started with Labview.pdf ‏901 KB

Hi Ashwin,
It is a good idea to first be able to communicate with the microcontroller using some sort of serial communication software such as "HyperTerminal" or "Procomm", etc. Refer to MicroChip's recommendations on this.
Once that works, then you are ready to use LabView.
Here is a link which covers many aspects of serial communication. Link - click here
You probably received a development kit. They usually have a readily available interface. It's been a long time since I played with the PIC, but I seem to remember that you need to program the serial communication driver (as well as at least a bootloader) to get the serial communication going. The driver contains the necessary protocols so that you PC can have a machine conversation with the target (PIC).
It sounds like a fun & interesting project. Please avoid to have replies to your personal email. By having the answers posted to this thread, you will get much more support and advice.
Have fun,

Hi Ashwin,
I am not familiar with the PIC Microcontrollers, but I am assuming you mean that you have the microcontroller sending out serial data that you want to read on another computer with LabVIEW. Please let me know if this is incorrect.
What type of data is coming out of the serial port? Is it ASCII, or binary? The reason I ask this is that the serial communication in LabVIEW is done through a protocol called VISA, which uses ASCII data to send and receive. You can later convert this data into whatever form you need, but this is what it is designed to read and write.
You can check the settings such as baud rate and data bits in a configuration utility called Measurement and Automation Explorer, or MAX. When you open up the MAX interface, you can expand the Devices and Interfaces entry on the left, and then expand the Ports entry to see your serial port. When you highlight this port, select the Port Settings tab at the bottom of the window, and you can see what the current settings are, and change them if you need to. You can also set these parameters in LabVIEW using the VISA Configure Serial Port VI.
You can also test communication in MAX by right clicking on the correct port and choosing Open VISA Session. Then choose the Basic I/O light blue tab, and then go to the Read tab. When you click execute, it should read in what is coming from the serial port. This will allow you to verify that the correct information is coming in before even trying to acquire the data in the LabVIEW environment.
In LabVIEW, the best resource to use the Basic Serial Write and Read example program that ships with LabVIEW. By examining the block diagram of this program, you will be able to see the basic programming flow of serial communication in LabVIEW.
I hope this information was helpful! Please let us know if there's anything else we can help with.

How to compare signals from two different .tdms files?

i'm developing a lie detection system in labview.so inorder for that i need to compare the threshold physiological signals from the .tdms file with the signals i acquire continuelsy from the subject for each question asked.i use respiration monitor and heart beat monitor together with the sensorDAQ to acuire the physiological signals.so which are the function i should make use of?i have the following toolkits
1. advanced signal processing toolkit
2. adaptive filter toolkit
3. digital filter design toolkit
4. biomedical toolkit
please give me advise on this.
thank you.
Solved!
Go to Solution.

Lie detector systems (polygraphs) generally work by looking at the physiological responses to the own subjects baseline, and do this in real-time. You could use a file that represents the stored "baseline" for the subject, but the overall environment, circumstances, general state of the subject, etc. may not be similar enough to easily see subtle changes.
From the stored file, you might determine a set of parameters or thresholds that indicate "normal, relaxed" for each signal. You could read the file into your LabVIEW program, process each channel, and save these parameters. Then when you have the new data, you can read the new data file in and process it in a similar way and then determine whether the parameters are outside the limits that you established for a "lie".

How can I tell if signals from two devices are truly synchronised?

Hi there,
How does one check that signals from two devices (two separate devices in a single X-series chassis) that should be synchronised actually are? I am using a PXIe6361 and PXIe4331 on a PXIe-1073, with Labview 2001 SP1 64-bit. All devices are using the Sample Clock from the 4331 device, and an AI Start Trigger, so they should be synchronised.
I thought that writing the signal data to file and checking the time stamp for each column of data would be the most accurate, but I have been told that timestamps are software created and therefore don't reflect the actual time that the signals were acquired by the hardware. When I do this, the timestamps vary by up to 150ms which is larger than I expected.
If I set the x-axis of the waveform graphs (on the GUI) to "Time" then it appears that the first data sample is taken at different times for the two plots (one plot per device).
If I set the x-axis of the waveform graphs (on the GUI) to "Ignore time stamp" (so that the x-axis just starts from 0 rather than a date-time) then the first data point occurs at "0" for both graphs. However, I'm not sure that this reflects the actual alignment of the signal.
What is the best way to check if signals collected on different devices in the same chassis are actually synchronised?
Thanks,
Claire.

Hi Lynn,
Thanks for your help and for sending the demo.
I understand the concept of how the signals will look if they're not synchronised and your demo shows that nicely. I guess I have been perplexed by someone else telling me that the timestamps in the output file (and following from that I assume timestamps on a waveform graph) do not give an indication of whether signals are synchronised. The reason they gave for this was that the timestamps are manufactured by the software, not the DAQ hardware. They suggested that I put the setting "ignore waveform timestamps" on my waveform graphs, and then check that both signals come in at the same time (i.e. both start at zero), but I'm not convinced about this.
When I use an analog trigger, neither the timestamps in my output file or on the two waveform graphs are synchronised. If I don't use the trigger, then there is far less disparity in the timestamps in the output file. I've attached two output files here, and my VI.
This is my first attempt to synchronise a voltage module and a strain gauge module on an X-series chassis, so I want to make sure that I'm achieving the best synchronisation that I can, and the difference in behaviour with and without the trigger worries me.
Thanks,
Claire.

Extreme Base station can't extend signal from Mini desktop ?TCP/IP settings

I have a Mac Mini connected to DSL via a lynksys 8 port workgroup switch. I had 6 rooms in my house connected to the router by ethernet wiring. Worked great for several years. Now 2 rooms cabling seems to have gone bad (mice or squirrels, maybe). To avoid rewiring the connection outlets or pulling wire again (Ugh!), we bought an extreme base station. It transmits the internet signal fine when connected to the ethernet network (roaming), but I cannot get it to allow clients to access the internet in WDS mode.
The base station is in a central location where there is not an ethernet jack. It picks up the airport signal from the Mini (with extreme card and yes, I have the MAC address of the Mini chosen).
Internet connection is "shared" on the Mini and the laptops have no trouble accessing internet within close range of the Mini. The laptops can't access the internet through the base station. I suspect it's how the TCP/IP is assigned. I have tried every possible combination in the Airport Admin Utility.
In the WDS diagrams, it always shows 2 or more Base stations, never a Desktop and a Base. Are these incompatible?

...but can't figure out how for the Mini....
When you select "Share your Internet connection with AirPort-equipped computers," click AirPort Options to give your network a name and password.
Since they are the "same" network does it matter?
If one has no encryption or is using weaker encryption it will be the weak link for others to access your entire network.
Normally, if you want to seamlessly roam between the 2 wireless networks, ensure that they are using the same network name (SSID), same encryption type, same encryption level, and same encryption password. However any wireless device connecting to the Mac mini's network will be on a separate subnet.
Now I've got to figure out how to get files off the Office Desktop from the laptops, should I set up afp for airport or ethernet?

Powerbook G4 Can't "See" Wireless Signal from Ubee Modem/Router

I was given a G4 Powerbook while out of town and it found the wireless signal in an apartment complex and a major airport just fine. But upon returning home it can't "see" the signal from my (Time Warner, Road Runner Extreme) Ubee modem/router. My Mac Mini's Airport sees the Ubee wireless signal fine, but the older Powerbook G4 can't. (The Airport signal in the menu bar has "bars" but they are grayed out.
Can an older G4 connect with the newer Ubee modem/router? Are there security settings that will allow this?
Tx,
WK

CRMDVM -- Thanks for the helpful info -- you are probably right on both counts:
The apartments where I picked up a signal is in an "old folks" apt. complex, meaning the router I was picking up was probably old -- compatible with the G4 lineage. And the Atlanta airport probably has a wireless system to allow the vast number of old and new computers that people carry to connect.
My Mac Mini connects via WPA2 Personal security code, and I set the G4 to the same security (in the Network preference pane) but still nothing. The Airport wireless icon in the menu bar is still grayed out -- it isn't the "blank" icon as when Airport is turned off. It has the wireless wave lines in the icon, but just grayed out.
Maybe the G4 is just too old to "see" the newer wireless signal from the new modem/router.
Thanks again for your help -- you definitely provided more than I knew. (btw, I'm just above you in Union County in Stallings).

Is it possible to get 2-ch signals from TDS2012 oscilloscope at the same time with LabVIEW "7.0"?

Hi, everyone.
I've been trying to get the signals from 2-ch of Tektronix TDS2012 oscilloscope at the same time using IVI connection with LabVIEW "7.0"
I've already searched this developer zone for the answer.
I've tried the famous example: "IviScope - Acq Dual Wfm Edge Triggered.vi"
and it gave me the error message like:
Error -1074110451 occurred at IviScope Initialize With Options.vi
Possible reason(s):
Driver Status: (Hex 0xBFFA600D) Primary Error: (Hex 0xBFFA600D) The Config Server module is not present on the system.
I think I've installed all~ the required softwares for IVI. For example, ICP 2.2, IVI engine 2.0.46, and tktds1k2k ivi (instrument driver for tds2012, in fact this one is for LabVIEW "7.1"... :-P)
TDS2012 and my computer is connected through HPIB(GPIB) and it is shown on the MAX (a GPIB instrument as well as an IVI hardware asset)
I've tried GPIB connection but it gives me asynchronous signals...
Is it possible to get 2 signals at the same time with LabVIEW 7.0(not 7.1 or higher) by any means?
What in the earth is the "Config Server" in this case?
I don't need to sticking to IVI and any method to achieve my goal will be welcome.
Could anyone give me the hint for this problem, plz?

I think your problem is that the instrument specific driver is version 7.1 and you are using the class driver with 7.0. You can create your own 7.0 driver by downloading the LabWindows driver and using the Import CVI Instrument Driver under the Tools>Instrumentation menu.
Since you don't seem to have a good reason to use IVI, why don't you try the native LabVIEW driver at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9139659CE034080020E748.... I believe you have all of the functions to setup each channel and then when you trigger the scope, both channels will be captured. You would then transfer each waveform separately. The data is always read sequentially but that's not important as long as both channels are triggered at the same time.

Can I use Airport Express to extend signal from my Airport Extreme and then run Ethernet from Express to my TV which requires ethernet to access internet?

As stated in title. I want to access Netflix but my TV requires ethernet connection. I would like to use Express to repeat Exreme sigal and then to TV via Ethernet. I only have one access point in house for cable modem so I'm using Extreme to broadcast though house. Will need to be able to input network key for Extreme secure network. Thank you.
Mike

Are both your AirPort Extreme and AirPort Express 802.11"n" devices?
If yes, you can configure the Express to "extend a wireless network" and it will provide more wireless coverage and the Etherent port will be enabled so that you can connect an Ethernet device.
This assumes that the Express is located where it can receive a strong signal from the AirPort Extreme.

No signal from Apple TV

I just got the new Apple TV and get no signal from it on my HDTV. I have an older Samsung TX-p3064w which has DVI and not HDMI.
I used a DVI to HDMI cable but get no signal at all - just a blue screen which means the tv received no signal. I know that DVI is not supported, but I was hoping to use this before I had to buy another T.V..
The T.V. can do either 1080i or 480p using DVI. I tried using two cables and no signal.
Does the T.V. have to do 720 in order to give a signal? Is there a certain cable I should try?
Any ideas on why no signal?

I was experiencing the same problem and discovered it is actually a 'handshake' issue. The firmware on the TV needs to be compatible with appletv. I solved it by updating the firmware for my Philips LCD 1080p tv. If you are using an older tv, you probably have to go to the manufacturer's support website to download the updated software on a gig stick and then upload it onto your TV. It should work thereafter. Good luck.

No signal from audigy 2zs line out j

Hey there....due to a virus, I recently had to format my dri've and reinstall XP and all my apps including software for my Audigy 2 ZS soundcard. Before the format I had my sound and video card connect to my TV to extend my PC display and audio to my home entertainment system. The external speakers were connected through the line out # jack on the rear of the sound card and I could hear everything playing just fine when my TV was on and the correct video signal line input was selected (video #2 in my case), but now I can't hear anything (video is playing back fine on the TV, just with no sound). I've checked my audio settings and I think they're correct - if there is a mute switch for any of the line out jacks in the creative audigy software or in windows' volume control panel I sure can't find it.
I'm sure its a settings thing because I didn't touch the cable connections, and I double checked to ensure they are all connected tightly/correctly as they were before the reinstall.
If anybody has any pointers, man that would be helpful....thanks!

Yup, my digital speakers are connected through the digital out jack.
Device manager shows the device working correctly - no issues or exclamation marks.
Not one ioda of hardware was moved, not one cable unplugged or any other config changed before or after the re-formatting of the hard dri've. Software o/s and applications only.
The soundblaster card properties in device manager shows no conflicts....everything is working fine, but there is a setting somewhere that is being missed I suspect; I have gone ever every option in all of the soundblaster audigy audio control software installed that came bundled with the card, checked online for latest drivers which I've got installed, and did a clean uninstall/reinstall using creative's 6 step-by-step guide. I also checked all windows xp based audio controls even though I've checked the option that enables the audigy controls to sync with the windows ones as you probably already know.
To my knowledge, there is no way to disable line out signal from this card - its there, you plug in your external and go. And with no config changes at all, no hardware changes, no cables unplugged etc. I don't know what else to do. (except email creative support which I did a few minutes ago).
Thanks Katman.
