Scan for instruments MAX, GPIB

Hi!
I've got one problem. I made a program in Labview with two devices directed by GPIB. Now one of them don't work correctly. I did "scan for instruments" inside of MAX and now it only "see" one of them. I checked the connections and they're ok. I don't know what more try, because I change nothing and before it worked.
What can I do in order to this instrument appears again?
Thanks!
Solved!

First I would double check the GPIB addresses. Secondly, make sure both devices are in a normal state. I recently had a power supply go into an error mode and then refuse to talk over GPIB until I turned it off and then back on.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How can I get MAX to scan for instruments on bootup?

I would like to setup MAX (or whatever SW component) to scan for GPIB instruments each time the computer is booted up. I've had one strange case where MAX somehow "lost" it's GPIB instrument configuration and the only way to recover was to manually start MAX and do a scan for instruments. I already do this for the VXI resource manager.
PS - I see the VISA configuration file, visaconfig.ini, has an "AlwaysRefresh" option line. Is there anyway to set this short of a direct edit?
Thanks,
Ed Perkins

Scott - If I understand you correctly I should be able to do the following:
1. Disconnect the IEEE-488 cable from my computer.
2. Manually start MAX and tell it to scan instruments (which it will find none).
3. Plug the IEEE cable back in and re-run my application (it uses VISA to control both IEEE-488 and VXI instruments) successfully.
Correct?
What prompted this thread was one strange event. After successfully running our app the previous night (and leaving everything powered up) the app failed all IEEE calls the next morning. When we went into MAX it mysteriously showed no IEEE instruments. Nothing solved the problem (computer reboots, etc.) until we forced MAX to do an instrument refresh. Perhaps something else did go on, but I thought
running MAX and forcing an instrument refresh on each boot-up (much like running the VXI Resource Manager) would be a prudent prevention approach, especially since the station operators don't even know about MAX.

I cannot find "scan for instrument" at MAX

Hi~
I connected GPIB-USB-HS cable between the laptop and Keithley 2602 device.
In MAX, I could find GPIB-USB-HS "USB0::0x3923::0x709B::016F05B4::RAW" under "device&interface"
However, I cannot find "scan for instrument" anywhere!
So, I coudn't connect equipment with laptop......
What is the problem??
(I use Window 7, and I installed NI driver.)

MAX crashes when scanning for gpib instruments

MAX closes without comment when I attempt to scan for instruments with a tektronix TDS3014B scope attached. This problem does not occur with other instruments.

I've tried scanning for instruments with the TDS3014B being 1) the only instrument connected, 2) one of many instruments connected and 3) not being one of the instruments connected. The scan causes MAX to crash in cases 1 and 2 but succeeds in case 3. I tried scanning with the TDS3014B connected on different computers and MAX does not crash. I attached the ni reports for those computers. I do not have another TDS3014B available to try. When scanning case 2 some of the other intruments connected are the HP8920, Agilent E3632A and Agilent E8257C, but I don't think having other instruments connected matters since case 1 causes the crash also.

Uninstalled/reinstalled NI visa 5.4, NI max now hanging (searches for instruments indefinitely)

Hi all,
I did the following and now NI MAX is hanging and searching for instruments indefinitely:
1) uninstall NI visa 5.4
2) install NI visa 5.3
3) uninstall NI visa 5.3
4) install NI visa 5.4 again.
I did all this because I have a GPIB instrument that max sees as a miscellaneous resource.
If anyone has any ideas please let me know,
Thanks,
Solved!

ed,
I would suggest installing the most recent version of NI-488.2 which can be found here: http://www.ni.com/nisearch/app/main/p/bot/no/ap/tech/lang/en/pg/1/sn/catnav:du,n8:3.25.123.785,ssnav...
Try scanning for the instruments in MAX after you have installed the 488.2 driver. You can also use NI I/O Trace or GPIB Analyzer to see if you can detect anything out of the ordinary. Take a look at these two links for NI I/O Trace and GPIB Analyzer instructions:

How do I find out if an instrument supports GPIB

I want to make a VI for HP 8712B RF Network Analyzer, but somehow the Instrument is not detected by the GPIB board. I used MAX (Measurement and Automation Explorer) to see if any instruments have been detected. It showed me an error stating that no instruments have been found. I checked the cable connections and made sure that the instrument was turned on. I just installed the GPIB board and it seems to have installed alrite. My guess is the instrument does not support GPIB. Moreover, the instrument has an menu option for HP-IB addresse instead of GPIB addresse (as seen on instruments I have worked on earlier like HP 34401A Multimeter.). Is there any way to find out if the instrument supports GPIB from LabVIEW or any othe
r software included in the package.

HPIB is just HP's name for GPIB. They are fully compatible. What GPIB board do you have? Does it show up in MAX under the Interfaces list? What are the settings on the Network Analyzer? HPIB address number? Is it set to write only? Can you talk to other instruments okay?
I would check that you can talk to other instruments that you know work on the GPIB and then decide to investigate the board or the instrument to find the problem.

ClamAV fails to scan for viruses in emails [CLAWS MAIL]

I've recently switched from Thunderbird to Claws Mail and ran into one small, but annoying, problem.
I want to use ClamAV + the clamav extension for claws mail to scan for viruses, however it does seem to have permission problems.
clamd is running, user and group clamav all have the relevant permissions as far as I can tell, however upon scanning my mail, I always end up with the following error:

How to read from a HPIB instrument using GPIB software?

How Can I read from a HPIB instrument using GPIB software and library functions in Visual Basic Environment? In HPIB we do not have to send query first but in GPIB we do? Although writing and sending a command is to a HPIB instrument is pretty much the same as a GPIB instrument. Any help or suggestion?
Thanks in Advance

HI,
HPIB and GPIB are the same thing at a low level in terms of instrument communication. They are both compliant with the IEEE 488.2 standard.
The difference is the driver you have to use. Each manuafacturer has to develop a driver to control the interface ont he host. For National Instruments interfaces you use NI-488.2 (which you refer to GPIB functions). For HP interfaces you need to use the SICL library. For information using this library in Visual Basic you'll have to look at the SICL documentation.
You can also use VISA (HP-VISA) which would allow you use NI interfaces or other buses in the future.
Hope this helps.

Scanning ESX24 Instruments takes too long

Logic Pro, v9.1.7, takes over 4 minutes to launch. It lingers over "Scanning Esx24 Instruments" for most of that time, approx. 3' 30".
Anyone have any idea at all what the bottleneck might be?

Is it possible to control a GPIB instrument by the instrument through GPIB

I'm having a Function generator, it has an in built GPIB, I'm writing an application on oscilloscope which also as GPIB, I have connected the GPIB port of oscilloscope to the FG GPIB port. I tried to send a GPIB command from the oscilloscope to the function generator. I wanted to know whether it is possible to control an instrument from a instrument through GPIB.

The answer is yes and no. There are three categories of devices:
talker/listener
talker/listener/controller
talker/listener/controller/system controller
Most instruments are "talker/listen-only". All they can do is act like a device on the GPIB.
You do run across a few instruments that are "controllers' as well. These instruments can be passed control from the system controller to temporarily control the bus, perhaps to calibrate themselves with a collaborative instrument. To find out if your instrument supports this, you probably need to look in the instrument's user manual.
The other option is for the device to be a system controller. This means that the device can control the bus at bootup (system controller) and run a host-side API (i.e., NI-48
8.2) to control an instrument. This sounds like what you are interested in.
I hope this helps.

Looking for LabView 6i GPIB-USB-A driver for Agilent E7401A

I am looking for LabView 6i GPIB-USA-A driver for Agilent E7401A EMC ANALYZER.

Hi,
There is a driver for this device available for downloading from the National Instruments Instrument Driver Network. Here is a link to the download page:
Multi-Environment Certified IVI Instrument Driver
Unfortunately, however, this driver is only available for 7.0 and 7.1. Unless someone else on this message board has created one for 6i, you will need to create your own.
The other option is to upgrade to LabVIEW 7.1, which I highly recommend. There are many improvements over LabVIEW 6, including Express VIs, Event Structures, and many others. You can see the new funtionality of LabVIEW 7.1 with a free online demo version at this link
Try LabVIEW 7.1 FREE Online
If you are interested in upgrading, you can call your National Instruments Technical Sales Representative at (888) 280-7645. Have a great day, and good luck with your driver search.

Check Scan for NI435X and elapsed time doesn't run in loop

Dear all Labview Experts
i have 2 questions
(1) i written program with Check Scan for NI435X (input to no of scan to NI 435X read ) and one with only NI435X read( to read in voltage) with constant input to no of scan,
the data i obtained is attached in 2 doucments; With Check Scan and without check scan ( the left column is temperature read in ( a formula is used to convert volt to temperature, right column is time)
strangely the program with check scan shows values in negative ==> Voltage read in is 0, strange, why is this so??? and why is there a diff?? Hope u understand my question
(2) For elapsed time, i want to find the total elapsed time for the whole program as well as individual cases, there is no "running" elapsed time or individual running time,
what happen is that when the each case end, the time will jump (e.g. from 0 at start, it will change to 5.35 at end of case) , is there any where to make the time run, i need it because some case required
c
ondition such as case will move to next after 5 seconds, but if above case happen, the vi will only stop if i put >= 5 rather than just place = 5
hope u understand,
does it help if i placed the condition as another loop , will it mean the same things
Attach are vi and some doucments, however as my vi contains PID tool kit as will as ni435x ni DC power which cannot be opened if you do
not have these kits.......however mayb u can help to look at the portion of timing as this is the main problem i faced now.........
Hope it is not too confusing for you to understand me...........
i can only attach max 3, the next post i will attach 2 vis...........

Thks Brian
Attached are 3 VIs
1.the first vi is the one with the check scan
2. the next two vi the only diff is the placement of the where i put the elapsed time and time of each case.........(without check scan)--the first
one is within the big loop, the other outside big loop -- the purpose i did this is because when i run the vi with the timing in the big loop, the timing does not run continuously but "skip". for e.g. Denature time: from 0 . it jump to 5.15s without showing the running.............
i will attached another 2 vi s in my next attachment
Hope this clarifies a bit
your help is really appreciated
thks

Looking for legacy PCMCIA GPIB+ Cable

We are looking for one of the older style GPIB cables no longer manufactured by NI. It is for the PCMCIA GPIB+ (it's a wider single row of pins instead of the newer double row narrower connector to the PCMCIA card). Any length is fine. Original part numbers are: 182362-01 or -02 or -04. Reply to email address below with prices. We'll pay for shipping.

Hi Jaegen:
The GPIB card you have is obsolete and has an obsolete connector on it. If you have the original cable shipped from NI with it, you should be able to get it to work. We, however, do not sell these cables anymore. I have included an attachement here of the pinouts for the connector you have in case you can find an old cable or possibly make your own.
Thank you,

Scan for and connect to networks from an openbox pipe menu (netcfg)

So the other day when i was using wifi-select (awesome tool) to connect to a friends hot-spot, i realized "hey! this would be great as an openbox pipe menu." i'm fairly decent in bash and i knew both netcfg and wifi-select were in bash so why not rewrite it that way?
Wifi-Pipe
A simplified version of wifi-select which will scan for networks and populate an openbox right-click menu item with available networks. displays security type and signal strength. click on a network to connect via netcfg the same way wifi-select does it.
zenity is used to ask for a password and notify of a bad connection. one can optionally remove the netcfg profile if the connection fails.
What's needed
-- you have to be using netcfg to manage your wireless
-- you have to install zenity
-- you have to save the script as ~/.config/openbox/wifi-pipe and make it executable:
chmod +x ~/.config/openbox/wifi-pipe
-- you have to add a sudoers entry to allow passwordless sudo on this script and netcfg (!)
USERNAME ALL=(ALL) NOPASSWD: /usr/bin/netcfg
USERNAME ALL=(ALL) NOPASSWD: /home/USERNAME/.config/openbox/wifi-pipe
-- you have to adjust ~/.config/openbox/menu.xml like so:
<menu id="root-menu" label="Openbox 3">
<menu id="pipe-wifi" label="Wifi" execute="sudo /home/USERNAME/.config/openbox/wifi-pipe INTERFACE" />
<menu id="term-menu"/>
<item label="Run...">
<action name="Execute">
<command>gmrun</command>
</action>
</item>
where USERNAME is you and INTERFACE is probably wlan0 or similar
openbox --reconfigure and you should be good to go.
The script
#!/bin/bash
# pbrisbin 2009
# simplified version of wifi-select designed to output as an openbox pipe menu
# required:
# netcfg
# zenity
# NOPASSWD entries for this and netcfg through visudo
# the following in menu.xml:
# <menu id="pipe-wifi" label="Wifi" execute="sudo /path/to/wifi.pipe interface"/>
# the idea is to run this script once to scan/print, then again immediately to connect.
# therefore, if you scan but don't connect, a temp file is left in /tmp. the next scan
# will overwrite it, and the next connect will remove it.

Screenshots
removed -- Hi-res shots available on my site
NOTE - i have not tested this extensively but it was working for me in most cases. any updates/fixes will be edited right into this original post. enjoy!
UPDATE - 10/24/2009: i moved the awk statement from wifi-select directly into the script. this did two things: wifi-select is no longer needed on the system, and i could tweak the awk statement to be more accurate. it now prints a true percentange. iwlist prints something like Quality=17/70 and the original awk statement would just output 17 as the quality. i changed to print (17/70)*100 then bash trims the decimals so you get a true percentage.

well, just to be sure you're doing it right...
he above is only an adjustment to the OB script's print_menu() function, it's not an entire script to itself. so, if the original OB script shows output for you with
sh ./wifi-pipe
then using the above pint_menu() function (with all the other supporting code) should also show output, (only really only changes the echo's so they print the info in the pekwm format).
oh, and if neither version shows output when you rut it in a term, then you've got other issues... ;P
