GPIB-Controlled XHR Power Supply and HP34401A DMM Conflict

Dear Experts,
I downloaded a driver for XHR Power Supply from NI's website and used
it to controlled the power supply successfully via GPIB cable in
LabVIEW. However, when I used HP34401A digital meter to measure the
voltage from the power supply in the same way via GPIB cable, the XHR
power supply was shut down automatically although the meter read the
measurement correctly before shutting down. Since I am a new user of
LabVIEW, I do not know if it is a conflict of GPIB-Controlled
instuments.
I would be most grateful if you could give me some advice and tell me how to solve this problem at your earliest convenience.
Thanks a lot for your attention and help,
James

You can set LLO with the VISA GPIB Control REN function. This is on the Instrument I/O>VISA>VISA Advanced>Interface specific palette.
You do not use the same VISA session for two different instruments. Each must be different and unique. If they were the same, then the be would be using the same address and your program would not work.
To make a sinlg VI that will control both instruments, just take the functions you need from each and put them into a single VI. The author of the XAN power supply drivers did a kind of lame thing. The Getting Started VIs do not have their controls and indicators wired to the VIs connector pane so you would have to change this before using the Getting Started in another VI. I've attached a simple example that shows some of the other functions along with some 34401 functions in a single VI.
Before you get going, I would recomend that you take a LabVIEW programming class. Information can bge found at http://www.ni.com/devzone/lvzone/fundamentals.htm.
p.s. You should know that your email address is not available to forum users. If you wish an example program, you can request it be posted here but you need to provide the version of LabVIEW that you're using and you need to provide the exact name of the XAN driver you're using. I found three and don't know shich is which.

How do I use LabVIEW to control and vary the voltage on my Agilent Power Supply and simultaneously record temp from 1 DMM and voltage from another DMM?

I am using an Agilent Power Supply to apply a voltage to a
thermistor to heat an Al chassis. I want to use LabVIEW to tell
the power supply to apply 5V for 10 minutes, then step to 7V for 10
minutes, etc. I am completely new to LabVIEW, so any help would be greatly appreciated!
In addition to that, I want to place a type J thermocouple onto the Al
surface and use a Keithley 2000 DMM to monitor the temperature (it has
a built in conversion from V to Temp for type J). I will also be
using another Kelthley 2000 DMM to record the output voltage of a new
uncalibrated thermocouple. I would like to collect the output
voltage for this uncalibrated thermocouple and the temperature reading
from the type J simultaneously. How should I go about doing this
in LabVIEW? I will be using version 6.1. The power supply
and DMMs will be connected to a PC using GPIB.
Again any suggestions would be greatly appreciated- I have no idea
where to begin on such a project. I have taught myself how to
make a basic VI- converting temp in oC to oF, but that is as far
as my knowledge goes.

What you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.

If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.

Labview 6.0 run-time engine will not control BKPrecision power supply.

I created a test program in Labview 6.0 to control a BKPrecision power supply and Measurement computing DAQ in our test system. I am able to control both intsruments from my PC which has Labview loaded on it. I created an executable from the application builder tool for distribution. When i install the run-time engine and executable on a new PC (Labview not installed), i am unable to control the BKPrecision power supply. The BK power supply is connected to the serial COM port of the PC.
Do i need to install drivers that are not included in the executable build?
Do i need to install VXIpnp (VISA interactive control)?
thanks,
Tim

tmann-
The API Drivers are often times for more specific Operating Systems than the others (Linux, Pharlap, etc.) and they are more easily accessible for programmers that want to (and have enough time to put up with the headaches ) of building speciality drivers off of ours. 99% of the time you just want the drivers that come up first when you type in your driver name (NI-VISA). As to versions, issues can crop up later from not using the exact same driver version but all the drivers are built off of each other (they hardly ever scrap an entire driver and start over) so the problems should be minor. Its up to you about switching. Unfortunately to downgrade version you have to completely uninstall the driver from Add/Remove Programs>>National Instruments Software>>Your driver and then reinstall the correct one. If you have time, I think it is well worth it to do it right the first time. Hope this is helpful!!

Pid: give a temperature wave by controlling voltage (power supply)

Hi all.
I have a system like the one attached in the message.
I have two working VIs: one that receive the temperature values and one which can read and write the voltage values.
Now: I need to control the system to have a sort of temperature value/values definied in the beginning (costant, sine wave, etc) by changing automatically ( I think PID is good to do it) the voltage.
I don't know how to "mix" the VIs to make it work, expecially I don't know how to relate the temperature and the voltage.
Hardware:
Temperature: NI 4351 DAQ traditional (NO DAQmx)
Voltage: HP Agilent 6033A (GP-IB controlled)
Thank you all

so.. i'll try to explain me better.
I have a peltier cell that is like a refrigerator (the hot part isn't involved in the system, so not a problem).
Upon it there's a metal box with the termocouple; in labview I see the state of the temperature.
upon the box there's the heater, connected to the power supply.
the power supply is controlled by the program in labview (by controlling the voltage).
How do I want to control voltage?
I want that the temperature follows a determined wave (a costant, a sine wave, etc...). If I do not give voltage to the heater, the temperature's box is going down and down. So I want that the labview program, controlled by a PID control, adjusts the voltage (controlling the Power supply) to make the temperature following the determined wave..
So:
I don't know how to relation the voltage with the temperature, with the PID attached in this message.
Hope this time i explained good.

To Control a Power Supply via LabVIEW

Hi,
I am really in the beginning of the learning LabvIEW. I am trying to control a power supply( Ametek XG
1500 ) via LabVIEW through USB cable. I have goggled several websites, but still do not have a clear idea
of how to implement such task. I downloaded COM drivers from www.programmablepower.com. Then, device and
my computer see the USB cable, but I do not have exact clue to make a good program to control power
supply.
I tried to make a program with NI-VISA with SCPI commands. Actually, I am not sure to write true
commands and I can not see the voltage or current value on the front panel. I have never write a program
to control any electronic device. Maybe, I can not see the basic step or not.
Firstly, I want to write a program which makes power on/off to the power supply. I do not know where
should I begin. Please any of you give me an offer to do this task.
Thank you.
Deniz

There is of course, the IVI driver.
I don't understand at all why you would install a different com port driver than the one that comes from Ametek/Sorenesen. In any case, I did not use the IVI driver. I simply created my own using Tools>Instrumentation>Create Instrument Driver Project. Pretty simple for me - I did a basic driver in less than a day. I would suggest you look over the instrument driver tutorial (on main idnet page). The commands are well documented in the manual. Be sure to get the termination characters correct. I can't provide the code I wrote as it was for a customer but if you post what you have written with details on errors you get etc, I'll try to help.

Monitoring 3750x and 3560x Redundant Power Supply and Fans

I need help for monitoring the redundant power supply of my switches (3750x and 3560x)
I have configured my snmp on my switches and is able to monitor interfaces, temperature and etc.
The problem is when I am monitoring the redundant power supply and fans.
I am using two Cisco C3KX-PWR-350WAC Modular Power Supply per switch.
The OID I use to monitor the PSU are the following:
Power Supply 1
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1003
Power Supply 2
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1004
When I do an SNMP walk, the value is showing (1) which means normal.
When I simulate a power outage on power supply 1 or 2 by unplugging the power source, the value doesn't change and is still (1).
Values: normal(1), warning(2), critical(3), shutdown(4), notPresent(5)
As for the Fans:
When I remove the fan module, I am able to get a notification that the fans are down, but when I plug back the fan module it is now using a different instance.
Below is my config for SNMP:
snmp-server community XXXXXXXXXXXXXX RO
snmp-server location XXXXXX
snmp-server contact XXXXXX
snmp-server chassis-id Cisco3560X
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
snmp-server enable traps transceiver all
snmp-server enable traps tty
snmp-server enable traps license
snmp-server enable traps cpu threshold
snmp-server enable traps syslog
snmp-server enable traps vlancreate
snmp-server enable traps vlandelete
snmp-server enable traps port-security
snmp-server enable traps envmon fan shutdown supply temperature status
snmp-server enable traps errdisable
snmp-server enable traps vlan-membership
snmp-server host X.X.X.X version 2c XXXXXXXXXXXXXX
Note: This problem is the same for all of my 3560X switches and 3750X switches. I am not sure if I am monitoring the wrong OID.
Thanks in advance

Hi ,
You are running an old IOS code , definitely you are hitting a BUG .
there is no workaround or I would say unfirtunetely you will not be able to get the correct power supply status via SNMP.
you need to use command line for this.
I mean "show env all "
**** if you want to know the Excat BUG that your code is hitting ,please contact TAC.
Thanks-

Macbook Pro power supply and grounding.

Hey Apple people. I noticed something disconcerting with the power supply on my MacBook Pro 13" (non-retina)
I have a stainless steel metal table in my kitchen. It is the same type of stainless steel table you find in restaurants.
I have my 13" MacBook Pro in a Speck See-thru case.
The MacBook Pro in it's case is sitting on a Rain Design "M Stand".
The Rain Design "M Stand" is sitting on the stainless steel table.
I am wearing a short sleeve shirt.
I am sitting on a fabric covered chair at the table.
The battery was getting low so I got out my power supply, which is the power brick with the two prong plug adapter.
I plugged this into a power strip and the other end into the computer.
While touching the case of the computer with one hand and leaning on the stainless steel table with my other bare arm. I felt a vibration through the fingers that were in contact with the MacBook Pro. I knew what was going on, and I got really concerned.
I tried an experiment.
I got out the extension cord that came with the MacBook Pro power supply and I changed out the two prong plug on the power supply for the extension cord. The extension cord has a grounding post.
When I plugged the power supply back into the power strip and connected the power supply to the MacBook Pro. I no longer felt a vibrating sensation when I was in contact with the stainless steel table and the computer.
I have other MacBook Pro power supplies and I always use the grounded extension cable with them, because it is located at my regular workstation area. This stainless steel table is located in my kitchen, and I was eating dinner and watching YouTube videos.
Just thought you would like to all know that when you don't use the grounded cable on your MacBook Pro. you become the ground.
Never using this power supply anywhere again without the grounded cable.
Thank you for your time.
Matthew Sievert

It depends on what you are doing. Yes, the power supply can get hot. This is normal.

Hi,
I've the same notebook. I've not had any hardlocks so far, but I've not seen so much flash movies yet. Anyway, I just tried closing running youtube-video tab on Kde4 + enabled desktop effects -> Everything's fine.
Anyway, perhaps we can collect some issues and solutions in this thread. Here are problems, that I encounter:

Issued solved:
- in order to make nvidia graphics working you have to disable Optimius in BIOS.
- Battery not recognized -- fixed after recend updates
- grub2 does not work. As soon as grub2 loads, the laptop reboots. -> stick to grub1 -- works now (either I did sth wrong the first time or a new version of grub2 fixes this issue)
- in order to make the touchpad work properly install psmouse-elantech from AUR
update: this is only a half-solution. vertical scrolling on the right edge works but graphical tools which rely on x11-input-synpatics still don't work. However, everything works fine with kernel 3.3. Once this in the main arch repos you won't need psmouse-elantech anymore.

LEOPARD, BATTERIES, POWER SUPPLY and other power issues

Hello ALL!
Happy New Year!
In fact I feel a bit scary last two days. Never had this kind of feeling since LB replaced :-D My scare related to the topics i've read here about batteries and leopard. Later below i will write my questions specific.
I just summarise my problem:
1. With battery installed unplug from mains leads to instant shutdown like it is some desktop.
2. The battery now does not have LED indication at all even in system it comes up as 100 charged and System Profiler reads information from battery.
3. When In unplug the laptop from mains first time, the battery did not give any indication of level of charge before i plug it in mains, after that it started charging and system indicator was trying to calculate remaining time till the end of charge endless...
4. This battery was working fine since 3 years without significant reduction in capacity. Before yesterday it was enough power to watch 2-2.5 hours DVD.
5. Battery seem to be dead. Mind that it was no slow reduction in capacity (keeping charge)
6. I was making calibration with some regularity.
7. While sleep mode with leopard seems battery drains faster even for me seems general operation after upgrade became longer.
So my questions are:
1. Is my battery really dead and needs replacement?
2. If yes, what are the symptoms of normal dying of battery?
3. Regarding all the posts which incline to Leopard as main cause of dying batteries should I run to buy a new one ....
4.... or it is hardware problem which lays in DC in board (heard also about battery board) which was discussed here but nobody directly gave indication that it was real cause of the problem?
5. Is it possible that even the battery will be brand new when i plug it in laptop it will die if it something related to hardware?
Thank you very much even for some smallest but helpful suggestion.
Ivan
PS: I am not in USA and not in any closest distance to Apple Store genius, most of my friends now on MB or MBP or iMac so even have nobody to try battery on exchange or even power adapter.

You didn't answer Illaass question, the newer minis have an internal power supply and should be connected directly to your mains, older ones have an external "brick". Since you mention the internal power supply, I guess your mini is one of the former, 120-240 V mains connected directly to the computer. If so, it should not be a problem using the tv power cord, if you actually have one of the older minis I don't see how you could connect the tv power cord, the contacts are really different.
So, if you have a new mini without power brick between the mains outlet and your computer, there should be no problem using any other mains cord, provided the contacts are the same. These power cords are massmanufactured by several manufacturers according to intnational standards and freely exchangeable.

An ATX P4 power supply and a MSI-6119 motherboard. Does it work?

I am reparing my computer. (Power supply broke down)
I found a cheap ATX 350W P4 power supply.
It is intended for P4 motherboards, and has the same connectors as my old PSU, except one more: the ATX 12V connector (4 pin , 2 yellow 12V and 2 black earth), that you normally have to plug in a 4 PIN connector called JPW1.
On a PII/III board such as the MSI-6119, there is no JPW1.
Apparently the PSU doesn't start up if the ATX12V connector iis not plugged in.
How can I make it work?

Thanks for the manual.
No beep when booting without RAM. No sound at all. power supply does not start.
I did the following:
1. Disconnect PSU from everything - do not plug ATX connector, but short circuit pin 14 (green) and 15 (black) of the 20 pin ATX connector - put in external power cable. The PSU starts humming.
Apparently, when pin 14C is pulled low, the ATX PSU jumpstarts. ( see http://www.duxcw.com/faq/ps/ps4.htm ).
2. disconnect all drives ( HDD, CD, FDD ) (power supply and ATA66 cable) - plug 20 pin ATX connector in motherboard - connect power cable - no boot;
CONCLUSION 1: Pin 14 is not pulled low by the circuits of the motherboard, which it should. why?
3. connect all drives ( HDD, CD, FDD ) with power supply cables to PSU and ATA66 cable to motherboard.
PSU not connected to motherbord
short circuit green and 15 of the 20 pin ATX connector.
Power supply starts, HDD and CD however not ( FDD starts ).
CONCLUSION 2: connection of ATA66 cable disables power supply to HDD and CD/RW
4. connect only power supply cables to HDD/CD /FDD and not the ATA66 cables.
No connection of PSU with mothetboard
short circuit green and black of the ATX connector. ( So Motherboard not implicated )
- Power supply starts, HDD / CD and FDD start also.
CONCLUSION 3: my HDD etc and internal power cables are OK.
And I am no step further.

MDD power supply and fan upgrade kit question.

Hello, Its been a few years since I posted anything here and I'm getting ready to (possibly) trade in my mirror drive door 1GHZ dual processor machine on one of the current imac-s.
I'm not real hopeful that putting much work into my current machine is worth it. Here's why:
1) crazy levels of noise - I wear woodworking hearing protectors when I surf the web. Listening to music on itunes is fine so long as you like a background of low level blow dryer noise!
2) I'm still running OSX version 10.2.8, I have been too cheap to buy the latest OS. I'm tempted to go out and spend the $119 on 10.5 but I only have the original 256mb of ram installed and since the min requirement of ram is 512, I know I'll need to spend an extra ~50$ on a 512mb PC2700 ram chip. My price tag to do a minimal update is rising...
3) I would love to neutralize the noise and install the Apple provided MDD power supply and fan retrofit kit that they sent me at no charge several years ago while I was still under warranty. But I never did because the tech at my local (Dayton Ohio) reseller told me that the kit only addressed high noise levels when rebooting in OS9. So I never bothered. Looking on ebay, I see where power supplies for G4's could fetch 75 or 100$ or so.
In summary, here are my questions.
1) Has anything come along recently to tame MDD G4 fan noise that is easy to install, cost-effective and most of all, something that actually works to decrease the noise?
2) To get the quietest, quickest performance with the current OS 10.5 should I cut my losses now and trade (or sell on ebay) my MDD, sell the new power supply and just purchase a new machine with the OS already installed?
Thanks a bunch in advance for any assistance...
from Bill.

Bill,
Carl has some pretty good points that I'd agree with - trying the replacement PSU and fans should quiet it down somewhat and replacing the stock main fan with a newer, quieter unit will also help. But I'm going to disagree with him on running Leopard on the G4's with a few reservations.
As you might notice from my profile, I'm running Leopard on my dual-867 MDD and find the performance acceptable; perhaps a little slower than Tiger in some respects but it does run well enough within the limitations of the G4's capabilities. The reservation I have about recommending Leopard on a G4 is the graphics card - without Core Image support (which you won't have unless you upgrade the video card) Leopard is going to tax the CPU more and may bog down in some tasks like Quick Look and Cover Flow.
In the end, whether to continue upgrading the G4 is a matter of use and economics. Tiger would be a fine upgrade with minimal cost and squeeze a few more years out of your G4 if you're not requiring software that needs an Intel CPU (like certain iLife '08 apps).

New power supply and sleep light question

I just got my iMac back with a new power supply and logic board installed under the Apple repair extension program. I had diagnosed the problem using the Apple troubleshooting assistant online. When I did this I also reset the SMU (system management unit) per the instructions with the troubleshooting assistant.
My computer is now working correctly but when I run Software Update I am prompted to install the iMac G5 Sleep Light Update version 1.0. I had previously installed version 2.0.0 back in July/05. I don't have the ambient light sensor iMac. I am a little nervous about installing this version or reinstalling the version I alreay have in my utilities. I realize this is a firmware update and cannot be reversed.
Anyone else experience this with 2 different versions of the Sleep Light Update, I don't seem to be able to find any info on the Apple site.
Thanks for any info
Scott

"reinstalling the version I alreay have in my utilities"
Please correct me if I'm wrong, but if you have it in your utilities folder, I believe that means that the installer folder has been downloaded, but the install was not done. I am thinking that once installed, it disappears from the Utilities folder.
I see no reason why you would need to do that firmware update if you don't want it. In the future, if you or someone else wants to do the update, it'll still be available on the Apple website.

Why does my FP-1600 take a 24V .5 Amp Power Supply and drop the Voltage to 11V at .5 Amps?

I have a FP-1600 connected to 4 FP-TB-1 bases. 2 FP-AI-100, 1 FP-TC-120, and 1 FP-AO-210 modules. I am powering the FP-1600 with a 24 V .5 A power supply. There are no devices currently connected to any of the modules. The power supply should be supplying 12 W, which should be enough to power the FP-1600 and the 4 modules according to the power requirement calculation in the manual P = 7 W + 1.15*#modules. When I install the third module, the FP-1600 stops communicating. Checking the power supply I see that the voltage drop across the power terminals on the FP-1600 is only 11V and then measuring the current being drawn it is .5 Amps, which is only 5.5 W, not enough to power the devices. When I unhook the power supply and measure the Voltage it is 24 V.
Why is the FP-1600 dropping the Voltage to 11V? Should I just purchase a 12V 2 Amp power supply?
Thanks for any help
Jeremy

Hello jqk,
You got it figured out. The maximum current that can be drawn is .5 which is too small. As the current being drawn approaches the maximum allowable current, the voltage will begin to drop. Eventhough the current you measure is .5A, the fact that the voltage is 11V means that the circuit requires more current to function properly.
As a rule of thumb, you want the maximum current your power supply can deliver to be at least the double of the system's maximum current consumption.

Solution for monitor power supply and raid 5 on x4150 server

Hi everybody,
a simple question :
my compagny have some server SunFire x4150 in some Datacenter, and there is a thing that we cannot really monitored remotly : the status of the 2 power supply and the status of the raid 5 of the server.
(i want to know if a power is down or if a disk is "dead")
We are using Nagios, cacti and munin actually, so can we use these interfaces for that?
if the answer is no, a script can be developed , if only i knew the command that can be used to take informations from the state of the raid5, i'll comunicate later the type of the raid card.
what are the best solutions availables for monitor those things?
thanks by advance

We have some x4150s but they're running Linux. There are separate solutions for each of the 2 problems.
1. For the power supplies, you can use the ELOM/ILOM system management interface (also used for monitoring the fans and temperature). If you've got it configured and connected to the network, you can set it up to email you about any events. We have the older ELOM firmware running, which includes the ability to add some actions to take in response to specific events. The new and supposedly better ILOM firmware doesn't seem to include this. Since this is IPMI compatible you can probably also hook into this using ipmitool or SNMP tools.
2. For the RAID card, assuming it's the standard Adaptec (rebranded as StorageTek) controller, you can install and use StorMan software (it's on the tools & drivers CD if not pre-installed). Once again you can configure email notification from the StorMan GUI, but this time it relies on OS host services to do the mail forwarding via the host NIC.
I'm not familiar with the details of your network system admin tools, but hopefully these tips will provide pointers on what hooks are available for these tools to tie into. Presumably there's also Sun N1 management software which can probably do this in a more built-in way, but it sounds like you've already got more than enough management tools.

NX6800GT-T2D256E, Power supply and 6-pin connector

My NX6800GT-T2D256E came with a power adapter: 2x 4-pin Molex to a 6-pin connector that goes into the VGA-Card.
I've noticed that I have an identical 6-pin connector directly on my power supply (a Cieftec GPS-400AA-101A)
According to the power supply's manual, it is a PCI power connector, seemingly for powering PCI-express VGA cards.
Of course I want to use that connector, as it seems to be the ideal way of powering the card, but first I compared the pin configuration to make sure it is the same thing - and found a slight difference.
On the Adapter supplied with the card, 1 of the pins is empty (not connected) while on the connector from my power supply it is connected to +12V
Basically the pin configuration looks like this:
1 4
2 5
3 6
On the adapter supplied with the card they are:
1: +12V
2: NOT CONNECTED
3: +12V
4: Ground
5: Ground
6: Ground
On the power supply they are:
1: +12V
2: +12V
3: +12V
4: Ground
5: Ground
6: Ground
Can I safely use the connector from my power supply or could the additional +12V damage my VGA card?

Your PC has a standard ATX power supply and physical sizes will vary slightly. You might want to measure the dimensions of your power supply. Normally the standard ATX PSU will measure 5.9" by 5.5" by 3.4". You don't want to get too far away from the dimensions of your PSU since the HP mini-tower cabinets are very tight inside. I prefer the modular model PSUs to help with excess cabling issues. www.newegg.com has many good brands. Not all PSUs are created equal. Look at the warranty period, amperage on the 12+ volt bus, specification level, i7 support, efficiency rating etc..
OCZ, Enermax, Corsair and Rosewill are all good brands as is Thermaltake.
