No Signal from appletv.

I've already I. Restored AppleTV via iMac 2. rebooted using the remote but still no signal. Cabling and TV working fine.

chosen the correct hdmi port as active input source of the tv?
this is required on most tv's hdmi does not support automaticly changing ports
if you did then I would test with another tv to be sure the tv is not the issue
and if that also didn't work then I would require the appletv as defect

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.

Disabling the MBP's ability to receive signals from remote control?

I own an AppleTV, my roomate uses a Macbook and I have the Macbook Pro, and they all use the same remote control and signal. Anytime we use the remote for the AppleTV it sends our notebooks into Front Row. Is there anyway to disable the mac's ability to receive the signal from the remotes?
Thanks.

Hi,
What you need to do is pair each Apple Remote so that it's only recognised by the Mac it's paired with. The following Apple KB Documents will guide you on how to achieve this:

Downloads/purchases from AppleTV versus iTunes

When I purchase a movie on iTunes (on my computer or iPhone) it immediately begins downloading and is added immediately to my "purchased" list on AppleTV. However, when I purchase a movie from AppleTV, most of the time it does not download and is only available on my AppleTV. I can usually go to my iTunes account and report the issue, but that means I have to remember to check....Anything I can do to make this happen automatically?

Downloading past purchases from the App Store, iBookstore, and iTunes Store

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.

How to read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine

How do you read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine?
I tried using a DAQ Assistant but the CAN port is not included as one of the supported physical channels even though all its drivers are upto date.
Please help..
Thanks.
Solved!

How to read and display a signal from my PIC Microcontroller onto Labview?

Hi,
I am doing a project on a Pulse Oximeter and i am trying to read and display the signal from my PIC Microcontroller on Labview? How do i go about doing it? I am using the PIC16F877 and also making use of the USART?
How do i implement and initialise the USART in PIC16? What are the steps to be taken, please guide me through the process? The link provides information regarding the USART connection, initialisting and stuff? Is it correct to use these codes in my program?Link: http://ww1.microchip.com/downloads/en/AppNotes/00774a.pdf
Also, i am using the RS232 serial interface to connect to the PC? The connector i am using is the DB9 Connector. Which template and VI can i use? Am i supposed to use the NI-DAQmx and VISA? Also, for my USART connection, i am using the MAX232 Driver which is applicable for my application as i am working with +5V. So far, i have been reading and trying out on Labview and the steps i have taken are:

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.

Error message when trying to access my iTunes from AppleTV

I have a frustrating recurring problem. Whenever I try to switch to my iTunes as the source on AppleTv I get a continously spinning cursor. When I look on my computer screen I have a message that says: "The movie file "Extract775D6949-A583#5251D.id" cannot be found. Without this file, the movie cannot play properly".
If I cancel this message then I can connect from AppleTv to my iTunes library.
Why do I keep getting this message. More importantly, what can I do to fix this?
Thanks.

Why do I keep getting this message. More importantly, what can I do to fix this?This message usually indicates one or more of your iTunes library files is a "reference" file for which one or more track "resources" has been moved or deleted (i.e. the path is broken). If you have QT Pro, examine your file "resources" in the "Show Movie Properties" window. Resources should point to filename you have opened. If they do not, then the file is not a "self-contained" file and is subject to such "resource" file path problems/restrictions.

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.
