Compact FieldPoint power supply

I have a cFP-1804 network module for and one 24V-5A QUINT POWER supply for my project. A cFP-DI-304 Digital input will be connected to the network module backplane, of course with its connector block. Does the power supply powers up the complete netowrk module with the digital I/O module(s) connected to the backplane? or the power supply must also be connected to the digital module through its connector block? I expect that supplying power just to the network module is enough, but this is not very clear to me from the user manuals that come with the eqquipments.

I have a cFP-2120 controller with a cFP-DIO-550 and it was necessary to supply 24V power to the module as well. But that was for the digital outputs.
I found the manual for the DI-304 on NI's site. http://www.ni.com/pdf/manuals/374168a.pdf It does not appear to require the voltage be applied to the module.

Outlet Power Scaling with Compact Fieldpoint

Does anyone have any suggestions on scaling outlet power? I have a fan which takes 115 VAC and .68 A but the PWM module can't handle that wattage. I've considered using an electronic potentiometer but have yet to find one which suppports my requirements. It's for a fan which we need to scale between 0 and full speed.
We have:
Compact Fieldpoint 2120
cFP-AI-112 Aanalog input
cFP-PWM-520 Pulse width modulation output
cFP-TC-120 Thermocouple module

You may want to look for a small variable frequency drive. Speed is varied by different frequency outputs. You could control one by outputing an analog signal to it, or even using serial communication.

Compact Fieldpoint Reliability

Hi,
Up until today I was convinced that Compact Fieldpoint was the way to go on our new plant but I have read several posts on this forum about loosing network connections to the units and other horror stories which make me wonder about their reliability in the real world. Like most people we simply cannot afford to have to reboot occasionally, this is unacceptable.
Does anyone have any experiences, good or bad with running a Compact Fieldpoint system for long periods (months/years)?
Thanks
Tony

Tony,
Been running one cFP-2020 for over a year now. Have not had to reboot. Unit operates in a large test lab with multiple variable frequency drives and other tests that generate a lot of electrical noise. 3 more systems in the cue that will use cFP for long term testing. I did have one cFP-2120 fail after one day on the bench. Caused by failure of switching power supply in the controller. Unit was repaired and no further problems 1 year after repair.
The only other problems I've seen were self inflicted and fixed during development.

Sorry for the long copy and paste. I read that I can upgrade the video card and power supply. But atm when I play world of warcraft at ultra settings, I tend to lag really bad in the new instances with the new cat expansion that came out. I wanted to know if I should upgrade the video card and power supply for better performance or just upgrade my whole pc tower. Fyi, I am running a Acer X243w lcd flat panel monitor if that helps too.

My brother has a high end laptop with a built in, high end gaming video card (I forget which one). He's able to run the game on full-on Ultra.
I have an integrated video card which games the game on.. 'cartoon'.. mode. It's lower then low. When someone shoots a powerful spell at me, I go into a DOS Prompt. (not really, but it's pretty bad).
Funny thing is, I can still kick my brother's butt in any PVP match he wants to set up.
But I guess his graphics are pretty....
As for which video card works best, I'd have to do some research. After that graphics update they did with CAT, it's kind of a toss up again.

FP-1000and FP-AI-110 power supply

Hello there,
I just set up my first FieldPoint unit and have a question concerning the recommended Power Supply:
When I read the FP-1000 QuickStartGuide , page 16, I thougt , there is no other way supplying the FP-AI-110 module but
by another external power supply .
But It seems , that the FP-AI-110 module is supplied by the internal bus, wihtout cascading power by the terminal. (See attached picture, where only the network module is connected to
an external Power supply )
So which way is recommended by NI ? Input Voltages at the analog module are limitede to max 5V.
Greetings
Beethoven

Hi!
I have in my lab FP-DI-301 and FP-DO-401. All works, even if I don't cascade V-C terminals, except the output module don't drive their outputs! I mean, V-C are used from output module to actually feed the output current/voltage. The power/Ready leds lights also with V-C not cascaded because the "logic" part of the modules derive power from backplane. Also the I/O interfacing circuits work, in fact I can see inputs even without V-C connected. This holds when the whole system has the same power supply.
Taking a look at FP-AI-110 manual, "Voltage and current inputs are referenced to the COM terminals, which are internally connected to each other and to the C terminals. All eight VSUP terminals are internally connected to each other and to the V terminals." and "The [c]FP-AI-110 has eight single-ended input channels. All eight channels share a common ground reference that is isolated from other modules in the FieldPoint system.". So, I guess, you may refer your inputs to another system, with separated commons. That's why you are told to connect V-C.

HT2811 If the display flashed short long short could the power supply be bad?

If the display flashed short long short could the power supply be bad?

Hello,
In order to determine what might be going on, I am going to need a little more information about your setup such as:
-what version of the cFP drivers are you using?
-where/what device are you outputting voltage to? at what voltage? how much current do those devices require?
-could you explain further by what is meant by '[at] approximately 30 seconds, all channels on that PWM shut off'. Are the lights on the modules still illuminated when the system 'shuts off' or do they remain on?
-Do you have another power supply you could try this with?
-Does the power supply meet the specifications for use with this module per p. 4 and 5 of the FIELDPOINT AND SPECIFICATIONS™ OPERATING INSTRUCTIONS FP-PWM-520 and cFP-PWM-520 Eight-Channel, 5 V...
-Does the power supply continue to output 24VDC even after the 'shut down'?

Macbook power supply for MBP?

Is it possible to use MacBook nice and compact power supply for MBP?
Thanks

Actually they are the same size. I have a 85W adapater and it pops right into the power connector on my MacBook. I did not have the MBP adapater plugged into the wall socket though. The pin spacing and arrangement appear the same also.
The MP adapater lists the output as 16.5 VDC, the MBP lists two output voltages; 18.5 and 16.5 VDC.
I am NOT going to try and charge or power my MacBook from the MBP adapter, but I think it would be short sighted on Apple's part to use the same connector on both adapaters if using the wrong one could damage either the MB or MBP.

PoE switch and Compact Fieldpoint

Hello all... Is it possible to connect my Compact Field Point Controller to a PoE switch (Power over Ethernet Switch)??? This is because some other devices on the same subnet require PoE (IP cameras) and I wanted to know if this can cause some sort of problem with my Cfp... Should I connect the Compact Fieldpoint to a regular switch and connect that switch to the PoE switch??
Let me know any suggestions...
Thanks a million in advance,

Hi Jaime!
Currently there are only certain products that support the PoE standard, unfortunately the cFP family is not one of them. The best you can do is connect your cFP to a switch and then to the PoE switch like you said and check if that works. Here is the document where the PoE and NI products are described:

Hope this helps!
Have a great day!!!

Power Supply failure...

I just had a power surge that killed my powe supply for the for Linksys Compact Wireless-G Broadband Router WRT54GCC. I tried to live chat for help with Linksys but the rep disconnected me after waiting for about 30 minutes. (Sorry...not relevant info, but just me blowing off steam)
Anyhow, does anyone know if (and where) I can find a replacement for it? Couldn't find anywhere on the Linksys site where you can order replacement parts. Does this mean I'm SOL and just need to go an pick up a new router?

Hi guys, I had two of the power supplies fail on the WRT54g's at roughtly the same time. Mine both showed low voltage output (measured at about 1v). So I dutifully took them apart and found two of the capacitors tops were bulging. Apparently this was a common problem due to a bad batch of electrolytic capacitors produced around 2000 - 2002.
So anyway the two capacitors are a 450uf 16v and a 100uf 25v and cost the princely sum of 50p from Maplin or RS components. They are easy to remove and resolder. You'll need a soldering iron, and a multimeter would be a good idea to test the voltages before and after. You'll also need a big flat bladed screwdriver to prise open the case. Hey presto I now have two working wireless routers!!!
Drop me a line if you'd like to know more. You can always just buy another power supply for about £11 but where is the fun in that! Much more satisfying to repair the old one. If you do buy a new one make sure it is 5volts and can handle 2 Amps

Issue: looking for a snmp OID to poll power supply status (Inbuilt Power Supply - no redundant power supply in this scenario). Possibly what we see in show environment.
CSE analysis:
I tried using the OIDs belonging to CISCO-ENTITY-FRU-CONTROL-MIB , like cefcFRUPowerOperStatus and cefcFRUPowerAdminStatus but it didn’t return anything.
NOTE: I have done all the snmp walks from the Linux server. Do I doubt it’s something to do from the snmp manager side.
Couple of observations. The CISCO-ENTITY-FRU-CONTROL-MIB talks about the field replaceable power supplies, so I doubt if it’s going to return the value for inbuilt power supply.
Second, I noticed that there are snmp traps supported for power supply and threshold setting. See configuration below. Is it that only traps works for power supply and environment related details?
Snmpwalk on cefcFRUPowerStatusEntry returns nothing:

Hi
I've got an ASA with redundant power supplies. An ASA5585. So I have the need to monitor them. :-) So how can we do it?
Also I've made a SNMP-Walk through the ASA v8.4(2)8 and it doesn't show up any ENV-MIB values. The
1.3.6.1.4.1.9.9.13 tree is not available. Are you shure it's available on the ASA?
Funny is also that the command "show snmp-server oidlist" from the 8.4 configuration guide is not available on the real CLI. I think the documentation guys were faster than the coders. ;-)
Kind regards

I had an Intel-iMac fried by lightening. UPS, surge protectors but it happened as I was reaching to unplug. Cold now. Could it just be the power supply? Can I replace that myself?

This is the full question since I couldn't get it all in the box.
I have some complex questions regarding an iMac, a Time-Machine backup, and iTunes on an iPod.
I live about halfway up an extinct volcano about 12 miles north of San Jose Costa Rica. Some months ago, we had a thunderstorm and as I reached to unplug my computers lightening struck about 50 meters from my house. I had an iMac with a 3-Tb external backup drive, a PC laptop and a laser printer on the same power strip. There was a definite surge and the light brighten and then power was lost for a few minutes.
When power was restored, the PC and the laser printer seemed to work fine but the iMac was cold.
First questions: Is is possible that the power supply was fried and not other essential parts? Would it be worthwhile to replace the power supply? Can I, with limited experience and tools do it or need I take it to a technician? My concern is that if the hard-drive is good, there is personal information on it that I don't want to risk.
Next question: Do I need to replace the hard-drive before taking it for service? How hard is that, can I do it? I have seen videos of the drive replacement on-line.
Those are my iMac questions, now the questions about backup restoration.
If there is a saving grace with this it is that the Time-Machine backup seems fine although I have only accessed the data through Finder. I replaced the iMac with a Macbook Air with significantly less mass storage and I can't just move files to the Macbook. My problem is that I have an iTunes library of some 10,000 songs on the backup and until recently on a 160 Gb iPod which was old and it crashed. I have replaced the iPod but have not tried to restore the iTunes library to it because of my confusion about how to do that. Can anyone tell me how I might do that or give me any insight into the process?
Thanks for any help you can give.

Quite possible, but working on iMacs is not easy, & PSU might be prohibitive.
Hopefully the Drive might have info on it, but even pulling that out can be a chore.

Shock Therapy - An Athlon64 / FX Power Supply Guide

I used to make a hardware list of all the components I would like to incorporate in my next
computer build. Normally...at the bottom of that list would be the power supply, not that I
didn't think it was important, it's just that my other hardware was so interesting! Today, power supplys
seem to take a back seat to blazing-speed CPU's, Dual-Cored processors, glitz and glamour
video cards...not to mention supersonic, heat-sinked RAM and modular, gizmoe'd PSU's promising not
only over-achiever specifications, but eye-candy as well. The lowly PSU....tucked up somewhere inside
it's dark and lonely loft....effortlessly supplying us with the energy required for important 3D imaging
or just funning with the latest games.
What a power supply does is rather simple. It converts your office or home's socketed electricity to
usable 3.3v, 5.0v and 12.0v energy...that's all. A power supply that cannot efficiently do this will-
over time-cause computer crashes, continuous reboots and shutdowns, and worse...expensive component damage.
And now, with faster processors such as AMD's Athlon64 and FX line of CPU's, never has there been a time, when
choosing the right power supply is so important! This article is written for those using these high-powered CPU's!
Well...Do we have your attention!?
If you are experiencing these problems, or still scratching your head over that last RMA....could be
your PSU is trying to tell you something.
To begin with, a power supply's ratings refer to its maximum output under ideal conditions. No power
supply is 100% efficient. In high-quantity manufacturing, power supplys may not put out any more than 60% of
their advertised specifications. In any PSU, that rating can be further reduced by the effects of heat
and electro-magnetic radiation. That's where "switching" power supplys come in. A switching power supply draws
only as much current that is needed from the AC input. Buying a hefty PSU with this feature will guarantee
that you will be paying no more for electric service, than you would with a cheaper, less powerful unit.
One of the most common causes of power supply inefficiency, and ultimately failure is dirt. Dust and
foreign materials can cause the beginning of the end for a power supply, by attacking the fan first.
It begins by slowing the fan down...thus creating heat through friction, then ultimately burning it out.
PSU's with high-quality ball bearing fans are a must. They are far more durable, and not as likely to
become noisier as time goes by.
As a general rule...a failing PSU will usually emit abnormal sounds, followed by unstable voltage readings....
then the computer crashes or lock-ups, with random shutdowns, and sometimes...refusal to even power-up.
If you think your power supply is on its last leg...better to deal with it now, or face the more serious dilemmas later on.
APM (Advanced Power Management)
APM is a feature originally developed by partners, Microsoft and Intel. It relates to a systems ability
to utilize different states in regards to a systems utilization of power. On, Off, Standby and Suspend
are examples...these are BIOS features, not PSU functions. APM only requires of the power supply, the
function to turn power on or off through an electrical signal, and the presence of stand-by voltage.
All ATX power supplys are required to incorporate this feature. However, if some components in a computer
are not APM-compliant, your system may encounter errors or freezes when going into hibernate or stand-by
modes.
ACPI (Advanced Control Power Interface)
It's the latest power management control that was developed by a conglomeration of IT corporations. This interface
is O.S. derived, rather than BIOS, and all ATX power supplys should be ACPI-compliant. You should not have to be
concerned about this feature.
Line-Conditioning Circuitry
A power supply component that helps control power levels, spikes and surges in
the most unreliable of home sockets.
EMI Filter
This circuitry smooths the fluctuations of incoming AC currents, also known
as Electro-Magnetic Interference - EMI filters are usually found in higher-end power supplys.
PFCC
Power Factor Correction Circuitry...smooths out sudden, initial spikes in power
delivery - reducing amplitude and preventing circuit overloads.
Connectors
There are five main connectors found on the latest version ATX power supply.
1) ATX main power connector - 20-pin, 24-pin, and 20 to 24-pin adapter.
2) ATX 12v power connector (4-pin to CPU)
3) Molex peripheral power connector
4) Floppy power connector
5) Serial ATA power connector
On newer SLI-certified power supplys, you'll find two 6-pin video card connectors.
Know What You Need
When purchasing a power supply, make sure your parts list is all-inclusive...know ahead of time, what you expect to
install in your system. You should also visit the motherboard manufacturer's site, as well as the CPU's. Most of the
products will have specifics regarding power supply requirements needed for that specific component. Unfortunately, you
really won't know how well the PSU performs until it is installed and running your system (hopefully!) This is the main reason we
recommend the most popular brands - power supplys that have shown a duration of manufacturing quality over the years. Those are
as follows: Antec, Enermax, OCZ, PC Power and Cooling, Tagan, and a few newcomers such as SeaSonic and Silverstone are
worth looking into.
If you believe you have found the PSU of choice, remember this: AMD recommends a minimum 350 watt power supply to run
Athlon64 and FX CPU's. To that, add the 30% for power lost to heat, and the subsequent electro-magnetic radiation. Hold on with that
calculator...throw in an additional 40% to 60% for the "potential" inaccuracies of specifications inherent in mass-produced electronics.
Pay special attention to outputs on either single, or dual rail +12v lines. A motherboard, CPU, and graphics card can consume up to
150 watts alone - before hooking up your remaining components. If running an SLI configured board, look for a PSU that is certified
to run that configuration...there's only a few PSU's that lay claim to that!
Broken down, you can look at it this way: An Athlon64/FX processor can use up to 90 watts off the +12v rail. High performance RAM
can take in about 25 watts for each stick of 256MB system memory from the +3.3v line. PCI cards will use about 10 watts each, while
an AGP video card can consume about 50 precious watts alone from the +5v or +12v. Hard drives? A 7,200 RPM drive...about 15 watts
each, taken from the +5v and +12v rail. Finally, but not absolutely is the optical drives...robbing about 20 watts each, also from
the +5v and +12v lines. So you see....not only is the +12v amp ratings of concern, but also the +5v line!
In doing the math...on a system incorporating an Athlon64 (say a 4000+), 2 sticks of high-end RAM, 2 or 3 PCI cards, 1 mid-to-high
end AGP video card, 2 ~ 7,200 RPM hard drives, and a couple of CD/RW or DVD/RW opticals...you're looking at a "base" requirement of 270 to 325 watts. That's for a running system...now figure boot-up loads, 30% for heat and radiation bleed-off, then a 40% safety factor for manufacturing inconsistencies...you've got a power supply in the 450 to 520 watt range!
Modular Power Supplys:
The pins that are used for the modular plugs are not very good at passing current. It's basically electrical resistance between the male and female components, and voltage "drops" are likely. In real world events, they will become loose, dirty, corrosive, and eventually burn. You can figure about 10% less efficiency with a modular power supply.
Now you can understand how manufacturing "tolerances" that are inaccurate by 40% to 60%, can have such a devastating effect on
the performance of your new system. If you follow these simple guidelines, bearing in mind the hardware you will be using, and what
your intended use of the computer is for...then it will be one less dramatic incident when pushing the power button for the first time!
Here's a neat little tool....a bit out of date - that can give you a basic idea of what you'll need in a PSU.
You can apply the percentages above, for an even more accurate assesment of your PSU requirements!

In doing the math...on a system incorporating an Athlon64 (say a 4000+), 2 sticks of high-end RAM, 2 or 3 PCI cards, 1 mid-to-high
end AGP video card, 2 ~ 7,200 RPM hard drives, and a couple of CD/RW or DVD/RW opticals...you're looking at a "base" requirement of 270 to 325 watts. That's for a running system...now figure boot-up loads, 30% for heat and radiation bleed-off, then a 40% safety factor for manufacturing inconsistencies...you've got a power supply in the 450 to 520 watt range!
Well, except the CPU, my system has all that you mentioned there (I even have 3 optical drives). And my 350W PSU has been rock solid for more than a year (BeQuiet, = Tagan, IIRC). I don't think a 4000+ needs 100W more than my 3200+ . And that link you posted says that the minimum recommended PSU for my system is 506W xD. Come on.
Oh, and in the place I work there are 6 amd64 with GeForce 6800 GT and 2GB RAM with 380W Antec PSUs. All 100% stable, of course.
I would only go for >400W if I wanted to do extreme OC (with overvolting), or SLI. Otherwise, a good brand 350W PSU is more than enough.

MSI KT3 Ultra-ARU power supply problem

Hello !
I am a lucky owner of MSI KT3 Ultra-ARU motherboard but have one problem. My power supply Fortron (FSP Group) 300-GT 300W seems to have some kind of incompatibility with this motherboard. In my case, the computer can't be shutted down by software. With BIOS version 2.5 it was impossible to shut it down with button too. With 2.6 it is possible to turn the computer off by button but software shutdown still don't work. PSU is working on ALL other boards I have tested so far normally. Somewhere in discussions (not in this forums) I discovered that also some kind of weird sounds occurs with Fortron supply on this board and that it is incompatible. Have anyone some clues to solve this PSU problem ? I am not able momentally to buy some other kind of PSU because Fortron is the only brand from higher category to obtain, so I would be like to solve this.....
Thanks for any info !

PSU is powering Athlon XP 1700+ processor, the other big power consumer is GeForce4 Ti 4200 GPU. I am not able read currents for specific voltage outputs, so I am not able to measure whole power consumption. Computer is working normally, it is NOT overclocked (but it is stable overclocked too) and the only problem is PSU shutdown by software (win & linux, both of them has this problem). From BIOS v2.6 it is possible to shutdown the computer by power button. If it is tried by software, computer resets itself and three beeps occurs.

Power Supply and Graphics Card Question for HP Pavilion a6432p

Hello!
I have the HP Pavilion a6342p, and I'm wanting to install an NVIDIA Graphics Card either 512MB or 1GB. However, I'm not sure what is the power supply to this model (most graphics cards are saying 300-350W supply required).
Can anyone tell me what is the power supply to this model, and what would be a good graphics card model to look at to upgrade my graphics card to with this model? I believe the expansion slots are PCI-Express, but I'm not sure on the power supply so I can get the right graphics card.
Thanks!
Nathan

Also, the links in my sig may prove useful.
[edit] err, the 9100 is an integrated video chipset. Are you sure that's the correct number?
No the 9100 is not just an integrated video chipset and is available in both AGP & PCI form.
The Antec is a good PSU but I would recommend getting something better such as the OCZ or Enermax as they have a higher +12v rail amp.
