Virtex-5 power up sequence

Hi all,
I need to supply one bank with a VCCO of 2,5 V, and wonder whether it is safe to connect it to the same supply I use for the VCCAUX.
The datasheets and also AR # 34289 say, that 3-stated I/O is only guaranteed for the sequence int->aux->o, however I'm not sure if simultaneous ramp up does fulfill this requirement. AR # 34289 explicitly states for the Virtex-6 that simultaneous ramp-up is OK, but I could not find this information for the Virtex-5.
Any help is highly appreciated!

Bill,
Re-reading through the whole thread, it is clear that in V5 we did not meet our goal of no glitch regardless of sequence.
If I recall, this was due to a design flaw in the level shifter circuitry. It was the goal to keep all the level shifters in a benign state until DONE was asserted.
Thus, the sequence of being powered on and configured, to loss of Vccint, and restoration of Vccint is a violation of the power on sequence for V5. That means that we do not know if it will glitch or not.
Sorry about the confusion. As noted, the flaw was fixed in later technology nodes, but even then, there have been issues with power sequencing. Safest is to follow both the suggested power on, and power off sequences in the data sheet. Anything that will result in bad behavior (glitching), or be a reliability issue, is noted in the data sheet.
I agree that what you have done is the safest way to insure an output will not assert until DONE is asserted.
I would also be concerned that any outputs dring inputs will power ON the Vcco of the bank in question, so even if you remove Vcco, the bank may be powered from forward biased Vcco clamp diodes which are on every IO pin.

SATA to eSATA and power-on sequence question

I have, in the 90's, seen mobo's fried due to the switching on/off of attached SCSI devices whilst the Mac was running. I was almost obsessive about the sequence - power up SCSI device, power up Mac, and in reverse, power down Mac, then switch off SCSI device.
Fast forward to 2008, and I am (finally) the proud owner of an early 2005 dual 2Ghz G5 tower. I have fitted my SIIG SC-SA4M12 4-channel PCI SATA card into my recently acquired G5. All four channels are connected to an eSATA quad-port internal to external adapter PCI bracket to run additional external drives in cases with eSATA connectivity.
My basic question is do I still have to follow the old SCSI power-on
sequence (power on external devices, then power on the G5 & in reverse,
shut down the Mac then shut off external drives), or is the G5's mobo &
SIIG PCI SATA card OK if the external drives are powered on/off whilst
the G5 is running?
Logic tells me they should be, as the SATA cables carry only data and
not power (the external drive cases are powered through their own mains
adapters).
I'm still following the old SCSI sequence, as I have no desire to risk my hardware..

Another way to look at it, might be a good option so that it's off when charging.
Actually doesn't really matter. It will make no difference to your battery life or charge life whether it is on or off when charging.

Power up sequence hardware device

I inherit a test fixture, we need to protect the DAQ card inside the computer.
the fixture is connected to the computer via the DAQ card, and the fixture has its own power.
The computer has Windows XP and it can be turned off by the Shut down method.
The computer can be turn on by pressing the ON/OFF pushbutton switch in the front of the computer.
To protect the DAQ card, the power sequence MUST be as followed:
Turn ON
       1. Press the pushbutton switch to turn ON the computer.
       2. Then, turn ON the test fixture.
Turn OFF:
      1. Turn the test fixture OFF
      2. Then execute Shut Down function to turn the computer OFF
Is there a hardware device on the market that do this sequence or prevent
the user from turn ON the fixture if the computer is not ON?

If a 5V output is available at a terminal of your DAQ card, you could use this to power a suitable relay that closes to provide power to the fixture.
Put a reverse biased blocking diode across the relay coil to trap inductive voltage spikes when the relay gets de-energized.
This topic probably should have been posted to Multifunction DAQ topic.
What model is your DAQ card?

Power up sequence

I had my computer, dsl modem and wireless router (WRT160N) plugged into a power strip. Everything used to work. The last month or two, when I turn on, I have to unplug the router from the back and plug it back in for it to connect. Yesterday I removed the modem from the power strip to a wall outlet. I still have to re-plug the router. Pulling that power plug in out and in will eventually break it plus it is a hassle.
What is the proper order for powering up between the computer, router and modem.

Hi dale331,
I have Verizon FIOS for my ISProvider. I have its Router and my D-link Router plugged into a Surge Protector Power Strip.
If something goes wrong, that you don't have a Computer on Lockdown from a Software Firewall and forget about it, you can have the computer on and simply turn off the Power Strip, then turn on the Power Strip, a minute later.
It works fine. If you have doubts, simply try it.

How can I power up the 8115 controller without using 1078 momentary contact switch.

I am using an 8115 controller installed in a PXIe-1078 chassis. I am rack mounting the system and I have numerous cables originating at the PXIe-1078 chassis that prevent me from using the front panel momentary switch. Is there a method to have the 8115 boot without using the momentary switch on the PXIe-1078 front panel?

Hello EdH,
Unfortunately there is no way to remotely control the power line of the PXIe-1078. Though the PXIe-1078 has a DIP switch on its backplane this only toggles the control of the Power from the Controller to the Backplane. With this you may be able to mimic a power on sequence but that is unsupported.

Multi-Chassis Power Up Time Delay - DIP switch on PS Shuttle?

We run into this problem with multi-chassis setups. The downstream PXI chassis have to be powered up first before the controller one.
How do you solve this in a world-voltage capable way? I know there are power-sequencing power strips for North America, but this is an added expense, and not world-voltage capable.
Would NI consider a time-delay DIP switch on the back of the PXI power supply shuttle? That could reliably provide controlled power up sequences and be world-voltage capable (90-250 VAC 50-60 Hz)

Craig,
Thanks for posting your suggestion. Unfortunately, we do not yet have such functionality on our equipment. However, I would encourage you to post this suggestion on our idea page. www.ni.com/ideas

LabVIEW 7 and Test sequence.

I'm trying to write a program in the LV7 with user controllable test Sequence. The user will define a test Sequence. Some of the subvis in the test sequence are common like power up sequence. The program needs to poll for cetain signal state before running any test.
I'm looking to get an advice on the main frame/structure of the program with modular approach. I just don't know where to start! I'm pretty OK with instrument control and getting the result. Any advise will be useful. Thanks!

There is a good test sequencer from NI named Teststand. Have you made a look at this product?
Creating your own test sequencer would take you normally more time and money than the product costs.
A hand written sequencer will have two parts: a executer and the steps. The executer will load the step and execute it. Depending on the result the executer will go to the next step. A simple mechanism will be to store the sequence in a config file. Use a header to store information how much steps are in the file. Use a section named "Stepx" for each step with x from 1 to N. Each step has a key named "Typ". This is in fact the name of a VI which will be loaded and run by the executer. We use the same connector pane for all steps so we are able to call it w
ith "Call by Reference" node. We use the config file reference and the number of the step to allow the VI to find more parameters which it will use for its work. Do not forget to give back a OK status and the number of the next step to execute.
The executer has to load the configuration file, load the VI of step1 and call it and then load the VI of the next step. 0 or -1 will indicate the end of the sequence.
Use named queues to transfer data between the executer/steps and the user interface.

COMPAQ Pavilion SR1410NX, Win XP continually cycles through start sequence

Hello-
Last week, my desktop shut down unexpectedly; when I rebooted it, it just recycled partially through the power on sequence, then restarted again and again. The fan blows, the HHD indicator light is yellow, and it looks for a disc in both of the two disc drives installed, then restarts again. I tried starting the computer with a Ubuntu startup disc, but it wouldn't recognize it and just kept cycling through the power on sequence. The monitor does not display any startup screen info at all. I recently replaced the power supply with the same model a few months ago, and everything was working fine until now.
I plan to pull the HDD and connect it externally to my laptop to see if it's good/bad. Any ideas what could be the problem?

What exactly do you mean by "the power on sequence"? When exactly does it fail?
You can unplug the disk drive and try to boot the system. If you don't get a complaint that it can't find a bootable drive, then the problem isn't the drive.

Record Results from sequence call inside of SequenceFilePostStepFailure Callback

Test Stand 3.1
When a step fails I use SequenceFilePostStepFailure Callback.
In there I have prompt:
1. Continue
2. Terminate
3. Terminate (thus calling a power down sequence file)
Problem is that when Option 3 is used. There are no results recorded from that sequence call because it was invoked from the Callback.
How do I force record results when that sequence file is called?

RecordResultsProblem1.zip ‏10 KB

Hello Jaws8you,
After looking into this issue further, it appears as if the link I posted has some great information but is not an exact fit for your particular situation.
Because results from sequence callbacks will not populate in the report, we need to make sure and have any results we would like included in the main sequence.
In your case we are just going to put the sequence call in the "Clean Up" tab, which will report the data, and is good programming practice.
So to fix this problem, let's go ahead and try this:
1.) Change the variable "Locals.ButtonPressed" to FileGlobals.ButtonPressed in the locations that you have it so far
2.) "Cut" the "Call Main Power Down" sequence call from the "SequenceFilePostStepFailure" step, and copy it to the "CleanUp Tab" of "Main Sequence"
Basically, that should be it. What this will do now is run the "Call Main Power Down" sequence when button 3 is pressed and skip this step whenever button 1 or 2 is pressed. The result is then published in the report.
This should work out the best for you, thanks for posting and have an awesome day!
With warm regards,
David D.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

Tour got wet - here's what it does - how can I tell if it is "fried"?

My Blackberry Tour (from 2009 - Blackberry device manager says I am running BB OS 4.7.1) got wet in a rainstorm (phone was outside, not submerged, the wetness indicator strip on the battery has not had a line appear on it but a tab inside the phone is all red) approx. 5 days ago - I did some of what I should have done and some of what I probably should not have done as far as patience, lack of patience, letting it dry (in gentle heat (no hair dryer, etc. or rice), giving it a try... Here's what it does - my main questions are - do I have any hope of rescuing my contacts data - unfortunately, never backed-up? If so, how?:
- Without the Battery in: Connected by USB cable to my laptop (plugged-in, USBs powered) (Windows 7; Blackberry Desktop version 5 (installed from the CD that came with the phone)) finds the phone in Windows device manager (Blackberry Smartphone connected via USB), as above, Blackberry device manager shows status as connected, can identify the phone's PIN, Blackberry Desktop Manager can see that the phone is connected (can see it's PIN) but shows that the device is in Disconnected State, the screen on the phone shows the battery with red X through it.
With a Battery In:
- the battery with red X goes away,
typically starts with a red indicator light, then changes to black screen with hour glass,
- then to black screen with "BlackBerry" and progress bar (showing boot progress?).
- Boot progress bar completes,
- the screen shows the Verizon logo, then
- I get a flash (sometimes longer than others) of my desktop picture (it's one of the pre-loaded ones that is not on the micro-SD card, which I have removed).
- At this point there is a new progress bar which indicates that the phone is checking security settings (I cannot remember verbatim what it says, but it typically completes and, since I probably shouldn't be powering it on, I will not do that to get an exact quote; suffice to say, that usually completes).
- In terms of the desktop, I can also see that, in addition to my selected picture being there , the phone remembers my alarm time at 6:40AM).
- A couple of times when I restarted it, I held down the escape/back button during the boot and launched the phone in safe mode ("safe mode" appeared at the top of the screen - a dialog appeared that explained safe mode and allowed me to click "ok" that I accepted that I knew what safe mode was.
- Whether in safe mode or not, it usually at this point returned to the initial power-up sequence, in a loop, between the red indicator light and the hourglass animation - it does not return to the screen with the "BlackBerry" logo with progress bar, just the aforementioned loop.
At this point, I have tried two batteries - both Blackberry OEM, but with known/potential issues: 1.) the battery that was in the phone at the time it got wet - is approx. a year old (in terms of use), but was holding a reliable charge for 3-4 hours of talk time and
2.) an older battery which may have been the one that was replaced by battery 1 or may be older - it almost certainly had diminshed charge holding capacity and had started the bulge that lithium batteries develop as the near death. These batteries were not obtaining much, if any, in the way of charge while in the phone plugged in, but did, outwardly (light changed from orange to green on a Blackberry OEM charger form the D-X1 battery; have not done a test with a circuit tester, etc.), accept a charge via the outside the phone method. When using the inside the phone method - prior to any outside charging - during the boot-up process, at the point at which I could see my desktop, the indicator light flashed with the orange light and/or the indicator that one typically gets when the battery is lacking needs a re-charge).
I have received and I am currently charging a new D-X1 Blackberry OEM battery, via the aforementioned Blackberry OEM outside the phone charger, for a go-around with the closest thing that I can get to a no problems battery.
OK, I am an **bleep**: I tried to re-boot the phone right away, I wasn't doing a back-up (though I thought that it was 1.) the reason that I was buying a Blackberry with an SD card - that this information was going to be portable and 2.) that I thought that the tech from Verizon, way back when I bought it, set the phone up to store the information on the SD card (no such luck, not there) or the SIM card - how could I test that? (which is, perhaps, why I thought that a backup was taking place). Anyway, as you can tell, I have tried to be as descriptive as possible herein to say what I am seeing, because there are a number of other people with similar problems posting in various places, but, not really the same problems (they are getting stuck on a white screen, not getting all the way through the boot that I describe, had a phone in the pool all day, don't care about the data, just trying to save the phone (I was lax about an upgrade, because I liked my phone and I had a decent outlay of cash in the phone to start-off - was pushing to make it to this fall, hopefully not much longer, to get the newer Blackberry Classic coming out... hopefully with my contact listing being ported over). That said, I have found plenty of evidence that suggests saving the phone is a real possibility, but the data may be more of a challenge.
Huge post, looking for thoughts - thanks for any consideration given to my problems.

if booted up with out all the way dry you might have fried it
put it in a bag of rice for a few days in a nice warm spot 90-100 F
then try it again if it still does the same thing then its toast

How to Restore a Lost iPad (iPhone) without Wiping !!

This is not question. This is a solution.
I lost my iPad, it was found, and I thought it would be wiped as soon as I turned it on and it found iTunes.
But here's what I found, contrary to the what the 'Genius Desk' told me at the Apple store.
If you go out to iTunes with another device, log in, and delete the 'found' device from the 'Find My Phone' list, BEFORE power up of the lost device, it should work without being wiped. Typically, you have your iPad setup for only your own routers, so don't power it up in their presence. And just to be safe, don't power up near 'public' WiFi either. Until you get into 'Settings' and turn off WiFi on the lost iPad (or iPhone), you are in jeopardy of it being auto wiped.
And as Paul Harvey said: "And now... the rest of the story." (You can skip the next part if you are an impertinent person with no regard for a classic tale.)
I lost my iPad 3 at the Denver airport in December's mad rush. My fault, nobody else's; I was furious with myself.
I submitted my claim at the airport lost and found, believing I would never see it again. (BTW, save yourself the trouble and use their online site.)
A friend of mine told me about 'Find My Phone', which also works for iPads. We logged onto iTunes, on his iPhone, with my password, and I was able see the name I had given my lost iPad. I told 'Find My Phone' to wipe my iPad and display my cell phone number on the screen, just in case someone "honest" found my iPad. I knew I had locked my iPad but I decided this was safest. They can always wipe it, but iTunes will never allow it's use, due to the original owner's serial number on file. It becomes a 'brick'.
Segue, 2 months later.
I bought a new Air 2 because I need an iPad to run ForeFlight, a pilot program for navigation in small aircraft. One week later, I get an email from Apple, telling me to contact law enforcement at the airport (Lost and Found), and they even gave me the contact phone number to call. Sure enough, the airport found my iPad. The way I figure it, someone turned it in probably the day I lost it, and it took 2 months for Denver Airport to process the "mountains" of stuff they have turned in by travelers over the holidays. I was just happy I have it back. I took it directly to the Apple store to see if they could turn off the 'wiping' procedure and restore my old iPad. Nope! No can do! Once you tell it to wipe, through "Find My Phone", it's a done deal. Then I remembered something...
I had not set up Find My Phone on my old iPad, at least as far as I could remember. Maybe, just maybe, there was a way around this. Well... I found it.
I was told that if my iPad connected to WiFi, even it it were publicly open, it would connect to iTunes and automatically start the wiping process. Well, maybe.
Fortunately for me, Denver Airport Lost and Found had powered up my iPad, saw that it was passworded, hit the off button (so they thought) and instantly called Apple with the serial number on the back. That is what prompted Apple to email me. Thank you Apple! Actually, they had put it to sleep, not turning it OFF. Over 2 months, the battery went dead, a good thing.
When I got it home, I began to think about the power up sequence. This iPad had been setup to instantly connect to my home router. If I charged it, and it connected, I feared it might started wiping, so I devised a plan. Worst came to worst, it would wipe and I'd start over. Here's what actually happened.
I live far enough from town, that only a few WiFi routers exist nearby, and they are all encrypted. So, I turned off my router and let my iPad charge, just in case it tried to connect when it had enough charge to come out of deep sleep. Within about an hour, it was up and running again. I went into the settings and turned off the WiFi. Then, I turned my router back on. This allowed me to use my new Air2 to go out to iTunes and list all devices on Find My Phone. Lo, and behold, there was a list with my old iPad and my new Air2. I removed the old iPad from the list. Voila! It was gone! Just to be sure, I copied any configuration I wanted onto my new iPad from my old iPad, manually. (This was more of a science experiment, so I was motivated to see if this worked. It's a geek thing.) When I was finished and ready, I re-enabled the WiFi on the old iPad. Sure enough, it connected instantly to my router, and nothing happened. The only thing it needed was 138 email updates, a few other things, and of course, an iOS update, performing flawlessly. My old iPad was back to normal. No wipe and just like I left it. There ya have it. A way out.
BTW, when I walked into the Apple store in Boulder, Colorado, they were all amazed that the Apple process had worked and I got my iPad back. Remember, I had been in there a week earlier and bought a new one, telling them my woes. That's when they told me it would be wiped, if ever found.
And what will I do with two iPads? You guessed, sweetie wumpums gets the other one.

Is there a way to force A Mini to recognize the HDMI as a sound output.

Is there a way to force the Mac mini to recognize the HDMI as a sound output? I have the HDMI going through a matrix switch and the video works fine but the audio is not recognized. My Apple TV has no problem with both audio and video through the same set up to a tv.

Some general checking:
Open System Information found in Applications->Utilities.
On the left side under hardware, click Audio. In the right
pane, Expand items if necessary to reveal the contents and
see if there is an HDMI listing. If so, click on it to get additional
info.
Also, have you connected the Mini directly to the TV? Narrows down
if it is actually the Mini or just how the Mini is working with the
switch.
Another possibility is that there is a power up sequencing issue.
Ran into a situation with my Yamaha receiver, Mini, and Samsung TV
that if things were not powered in the right sequence I could only
get two channel audio and sometimes only internal audio. With my
setup, I needed to power up the TV (waiting for it to come up completely
showing the searching for signal box), power up the Yamaha, then finally
power up the Mini. Also, after all this, if anything was switched, I would
end up having to reboot the Mini to get audio the way it should be.

HP Deskjet 3054A Wireless setup without access to router.

Hey everyone,
I own an HP Deskjet 3054A, and I would like to be able to print wirelessly. When I go through the wireless setup, it tells me to either: 1) enter a PIN on the wireless router or 2) Use WPS (Wireless protected setup). The problem is that I don't have access to my building's router (I'm a student, afterall).
I know some HP printers have a feature where you can plug it into your computer via USB, and have it set it up for wireless; mine does not seem to have that, as when I open up the HPLIP (HP printing software for Linux--- yes, I do use Linux), and add the device, and select "Wireless/802.11 (requires a temporary USB connection and is only available for select devices)", and connect the computer to the printer, and click "Next", but it says "No wireless capable devices found". I assume that this is because the printer is not one of the aformentioned "select devices". Is there anyway of enabling this feature? I'm not afraid of loading custom firmware or writing some C code if neccessary I'm a nerd afterall!
I'm using Ubuntu 12.10.
Thanks,
Jordan

OK, this model does support an ad-hoc style wifi connection, however only for the first hour after its first power on sequence (or a reset of the network settings).
So, sorry, I think you are stuck with a USB connection.
