I am wondering if anyone has tried using two NI PCI2 1429 frame grabbers in the same computer to get images from two cameras at once. Will the two framegrabbers campture images simutanously or will they switch back and forth?
Thanks!

Bertan - Series 225 VISA issues
I am trying to use the Bertan 225 VISA driver. However, using the driver I cannot turn on the voltage (it does not produce any errors and the code it puts out seems to match the user manual).
Does anyone have any experience with this? Or any ideas?

NI-MAX VISA Resource viLock, IDN? and viUnlock and VXI-11 instruments
I have a list of VXI-11 intruments that recognize TCPIP resource strings of this form "TCPIP0::10.AA.BB.CC::INST1::INSTR" with different IP addresses. I connect to these VXI-11 devices manually in NI-MAX Network Devices Tree and open a session. I closed NI-MAX and later I restart it. The NI Trace shows that any time I open NI-MAX it will automatically search for instruments of my previous TCPIP list. I could see that each connection send a viLock then an IDN? then viUnlock. The time taken between viLock and viUnlock is around 40 ms but if in this time some other program want to acces my device it will receive "Device not accessible" because NI-MAX locked the device.How may I prevent NI-MAX to start do this automatic search for all VXI-11 devices stored previously in NI-MAX? How may I prevent NI-MAX when searching for VXI-11 device list to send viLock and viUnlock in the sequence: viLock IDN? viUnlock and send only IDN?

NI PCI-GPIB card not working NI Max or Labview
Hello,
I have a national instruments PCI-GPIB card. My system specs are Windows 8 PC, 32bit, pentium xeon. I have installed the NI 488.2 16.0.0 as well as NI VISA 16.0 drivers. I have followed correct order of installation, which is to install the drivers first, then the hardware. When I connect the PCI-GPIB card, my windows device manager shows yellow exclamation mark. I then manually choose the PCI-GPIB driver from National Instruments GPIB Interfaces. Till here, no problem.
Its' when I open NI MaX, expand Devices and Interfaces and that the card has no name, NI Max gives me no option to search for instruments, or anything. Since the card has no name, I cannot call it using the Visa Resource name in Labview. Any ideas why this is happening?
Thank you so much.

What does it mean if a software version includes hex values?
Typcially I use NI-MAX (measurement and automation explorer) version 5.10f0 at my workplace.
I downloaded a version of NI-CAN for testing and the software package came with NI-MAX version 5.1.
What does the extra hex value "0f0" on the version mean? The hex value doesn't seem on par with traditional naming conventions for updated software versions. I can't seem to find any details on the website that could list the differences (if any).
Could somebody give me some insight into what that hex value means? Are both versions technically identical?

Lecroy WaveSurfer 3054 VICP connection issues
Hi, I am trying to interface with the wavesurfer 3054 which only has the option for TCP/IP connection. I have installed the VICP passport however my machine does not accept the resource string VICP::ip address. Using the string TCPIP0::ip address::inst0::INSTR works however it only outputs WARNING : CURRENT REMOTE CONTROL INTERFACE IS TCPIP. Any help to fix my issues would be greatly appreciated.

Help sending command packet hex values to serial connection? Piezoelectric element control
I'm trying to control a piezoelectric element that connects to the computer via serial connection. The command set documentation provided by the supplier provides the formats for the command packets that need to be sent to the serial connection, but I'm having trouble figuring out how to do this in labview.
The first command packet I need to send is a set of four hex values, that I bundled with the hope of sending to the Serial Write function, but the wire is broken and the error reading says that the Serial Write input and the cluster output are different types and therefore incompatible.
I've read some other places that I need to use a byte array and then convert that to hex, but I don't really understand this instruction. If this is the solution, can someone please elaborate for me and tell me where in the menu I can find the byte array, and why this is the solution?
Here is a photo of my wiring error: http://imgur.com/3enNZfR

Alternative voltage control to USB-6009
Hi everyone,
I am using USB-6009 in order to control the voltage across 5 identical LEDs in parallel through using labview which will be later on used for PID temperature control ( the connection can be changed to series if u suggest any other solutions). Each LED needs 30mA and 5V. The USB only provide a maximum voltage of 5V and 5mA. Is there any alternative NI control hardware that I can use instead of the USB-6009 that is more efficient for generating enough voltage and current for my application? Or if you know of any alternative circuit connection for fulfilling my application?
Thanks

Problems with the ethernet to GPIB connection
Hi guys,
I'm having trouble getting any data (except erros^^) from an Ahlborn Almemo 5690-1M
I'm using as mentioned an Ahlborn Almemo 5690-1M which is connected via a GPIB to Ethernet adapter to a small ethernet-switch that is also connected to my Notebook.
On my Notebook there's a Virtual Machine Installed(Win 10 Pro) an in that Virtual Machine I have installed LabVIEW 2013 together with the NI Systemconfigurator, NI VISA, NI-Serial and NI-DAQmx.
My problem is that everytime i try to use the VISA Test Panel and click on "Read" it says "VISA (Hex 0xBFFF0015)" and if I click on "Read Status Byte" then it's prompting me with "VISA (Hex 0xBFFF003A)", up untill now i haven't found any solution for my problem and this is driving me crazy, please help me.

Error when connecting a power source
Hello,
I am trying to connect a HMP4030 (fitted with a HAMEG HO720 interface card) power source by Rohde & Schwarz through the NI VISA interface via C++ through USB. I have installed all the correct drivers and the device shows up in the device manager and in the COM ports section of the Windows 10 Device Manager. The device is also detected by the NI VISA MAX application with resource name "ASRL7::INSTR". Also the port settings on the MAX application match the port settings in the device manager, so I assume the PC recognizes the device and reads out its settings correctly. I can't connect through Visual Studio either, because I'm not sure about the resource name to input for initialisation of the device (I've tried following the protocol in the added manual, but no success) .
When I open a VISA test panel on MAX, it reads out all the attributes, except the 'Is Port Connected' one:
VI_ATTR_ASRL_CONNECTED :
Error VISA: (Hex 0xBFFF001D) The specified attribute is not defined or supported by the referenced resource.
I can't send SCPI commands through Input/Output either.
I have also tried the HMExplorer, which is a program of the device itself, and it detects the device but says it cannot connect...
Am I missing something or doing something wrong?
Please let me know if you need more information to answer this question.
Best regards,
Dorian

VISA Timeout error
I am very new to using VISA library, hopefully someone can point me to the right direction.
I have an application (Visual Studio 2013, vb.net) that is used to control fiber optic switches via serial, utilizing USB-Serial converter. Everything is working the way it is supposed to when I try to communicate with device using exsisting library.
I am trying to evaluate NI VISA library(VISA.COM 5.7) to replace my current one.
When I try to access my device using VISA by sending *IDN? , i get VISA timeout error.
However, if i access my device using current library and then again using VISA i do get a proper response.
This behavior is device specific. If I use the same program and try to communicate with other devices using VISA i do get a proper response.
The device is LightTech Switch LT3000.
Thanks in advance for any suggestions.

Interfacing with INSTRON 8800
Hi,
I am trying to perform control of an INSTRON 8800 series device using LabVIEW. I have noticed several old posts (http://forums.ni.com/t5/forums/v3_1/forumtopicpage/board-id/140/thread-id/46152/page/1) concerning INSTRON device drivers and I was wondering if any one had any more recent experience dealing with control of this, or a similar, system.
I have searched the NI instrument driver network for drivers to no avail, but I do have a copy of the INSTRON IEEE-488 programming guide so I could develop some if required. The solution to the forum post mentioned above was a using the Bluehill ActiveX API, does anyone have any experience following that route?
Thanks,
Mike

Controlling syringe pump (Harvard Apparatus 33), commands not working
Hi all,
I'm trying to control a Harvard Apparatus 33 pump with a cRIO 9063. A pdf for the pump's manual is here. Right now I'm having trouble getting the pump to listen to most of the commands.
In my setup, I'm using a 6p6c cord to DB9 connector to connect to the DB9 port on the cRIO. I've checked that the baud rate is 9600 in the code and on the pump. The pump's address is 0.
The VI attached is something I made to test out writing commands. The pump has responded correctly for the <cr> command. The pump stops running, and the remote LED comes on, indicating that the command was received. So I believe my cabling is good. However, if I try any other command, the pump doesn't respond. Part of me thought that I got the syntax for the command wrong, so I tried many different versions:
- RUN<cr>
- 0RUN<cr>
- 0 RUN <cr>
- 0,RUN,<cr>
At this point, I'm at a loss for what it could be. I'm getting in touch with Harvard Apparatus to see if I'm missing anything obvious. But while I'm waiting, do any of you have prior experience or suggestions I could look into? Let me know if I should supply more info.
Thanks!
