Fail to communicate with the controller of pump ISCO D series

Hey everybody,

I have an ISCO D pumps controller (which is connected to a syringe model 100DX ISCO pump) series I want to control using RS232 on Labview. I don't have their LabView Toolkit that Teledyne has mentioned in their technical Bulletin (TB06). In addition, I would like to automate my test, so using the Labview Toolkit will be not too useful.

The problem I face is not being able to communicate with the controller via hyperterminal or LabVIEW.

I ran their (mentioned in TB06) integrated series test and communicate as expected. I also tried to run their program remote pump (mentioned in technical Bulletin 19 of Teledyne - TB19) which seems to do what is expected as well.

I tried to talk about using LabVIEW first using the vi that I joined, and I saw nothing on the buffer. So, I moved to hyperterminal.

But when I try to send the command 'remote' listed in TB19, it doesn't seem to do anything. There is no answer on the hyperterminal.

There is mention of a DASNET Protocol, and I found the .dll file that I also moved in my Windows System 32 folder. It did not work even after that too.

I have attached TB06 and TB19. Let me know if you have other ideas how to do to test it.

Please let me know if you need further information.

Thank you

Hey everybody,

After going through their best manual, I found the way to correctly send a frame. The manual at, www.isco.com/pcfiles/PartPDF/SL000004/UP00194U.pdf, section 7 specifically, it is intended.

For the purposes of anyone who stumbles across this thread, here's an example.

If you have your.

Destination (the pump regulator) ID = 1

the source of the (computer) message = 00

and you try to send the message to DISTANCE that would turn the controller in "REMOTE" mode

Then you would send '1R006REMOTE1B', where 1 is the ID of destination
R is right to recognize the previous received message

00 is the ID of the computer

6 length of command

"REMOTE" the command itself, must be uppercase

Checksum 1 b (which changes with the command of course)

And you can do the same thing in LabVIEW, you can enter '1R006REMOTE1B' in the VISA write while keeping everything else the same as the snapshot of the vi I sent previously.

Dennis, actually do not have the CD itself, but I assumed, would nothing more than an executable since I downloaded the demo driver for LabVIEW (http://www.isco.com/products/appnotes.asp?PL=105 under utilities) pump. I am currently trying to locate the CD here at the lab, and I will update this thread if I find something useful.

I guess that my problem has been resolved.

Thanks for your input in this Dennis.

Kind regards

Sandeep

  • Software BlackBerry Blackberry Link fails to communicate with the device

    I hope that there could be some additional elements that could help with a problem I've seen with BlackBerry link. We have a user who has three computers he uses to back up his passport for Blackberry (depending on its location at the time). A laptop has started to display the communication error, it is stated in the subject line. BlackBerry connection on two other devices have no problem of communication with the phone.

    The device works on OS 10.3.2.2474, although the issue does not appear to be tied to a software update. We confirmed that the user was able to save his device to the affected machine after it has updated to this OS level.

    Initially, when it connects the device to the computer, the BlackBerry Device Manager does not detect a connected device. After change of the cable USB and the realization of step 2 below, the Device Manager and link show the connected device. However, the link always displays the communication error. The user is a local administrator on the system.

    I tried the things:

    1. update to the latest version of link.

    2. retrograde to Blackberry link 1.2.3.56, which is the version installed on two systems of work.

    3 uninstalled link 1.2.3.56 and performed a manual cleanup of old files, such as noted in Blackberry KB35666 http://support.blackberry.com/kb/articleDetail?articleNumber=000035666&language=English, to delete the files from the driver to the previously installed version.

    4 reinstalled link 1.2.3.56, which gave me a perfect match for all the drivers on the affected system and two systems of work.

    5. manually created firewall rules that appear on work mDNSResponder.exe, nginx.exe and tunmgr.exe systems. The application for peermanager.exe rule created on an affected system.

    6a played with .NET. The system was originally installed 4.51. I uninstalled and installed 4.0 (which is the version required by the 1.2.3.56 link). Later, I've upgraded to .NET 4.52.

    7 off completely Windows Firewall and antivirus on the system. Neither touched the issue.

    8 connectivity test using another profile of Windows user on this system and later another device Blackberry OS 10. Reproduce the issue with the two tests.

    9 Ran through all the other suggested steps in the article noted in step 3. An oddity I noticed during these controls: under the Windows user profile, I am unable to ping the IP assigned to the device. This prompted the tests with the Windows Firewall and AV out. However, when we tested with a different user on the same system (with Firewall and AV) on profile, we are able to ping IP assigned to the device. This allows however for us to communicate with the device via link, however.

    Not to mention that the redefinition of the system (which, in my opinion, is far too radical to get this software to work), I hit a brick wall with items to check then. Has anyone else experienced this problem and it is resolved through a different way? Any comments would be greatly appreciated.

    Well, I guess everything he needed, it had happened to a point where I thought I was out of options. We finally got this device communicating by link.

    I had run across this article during my first troubleshooting http://support.blackberry.com/kb/articleDetail?ArticleNumber=000035829 and it is a problem, because we already had 4.51 .NET on the system and tried to reinstall it think.

    I went down the .NET 4.5 system, and of course link works again.

  • Error: "unable to communicate with the TWAIN device" with brother MFC7820N

    Original title: can I connect a scanner through a switch?

    I'm trying to analyze something like I did it many times with my brother MFC7820N hung on my tablet. But recently, I replaced a 2nd router I had in my system that failed with a new Dynex switch.

    I have my internet modem and 2 computers connected to a Linksys wireless router. I have another ethernet cable connecting the router to a new switch. I have my 2 printers attached to the switch. One is a Brother HL-2700CN color laser and the other is a brother MFC7820N mutli-function. It use PaperPort to scan stuff on him, since provided on the CD with the device.

    So today I open PaperPort and click the Scan button and it appeared an error saying unable to communicate with the TWAIN device box.

    So I clicked on a doc shown in PaperPort that I had scanned a few weeks ago and I click right and select Print and printed to this MFC7820N.

    Then I come back to click on scanner again and yet again, it appears that box. So I watch and WIA-Brother MFC-7820N LAN is displayed in the Scanner marked drop-down list box. So I switched the power of the MFC and tried again and it still appeared that same box again.

    OUCH! I'm going nuts! You have any ideas?

  • Questions of UPD on 4700dn printer - unable to communicate with the printer

    Hello!

    I'm testing the UPD on my laptop which has Windows 7 64 bit on my network printers all in my building. All network printers work fine except one... Color LaserJet 4700dn.

    When you use the UPD interface when you try to print, I try to use the IP address of the printer and it cannot connect. "When you use the search for network printers option, it recognizes the printer, but when I try to connect, I get the error ' unable to communicate with the printer.

    I changed the host name of the printer, changed the IP address on this subject, I can ping the printer and print using the print server, I rebooted the printer... Even got a older laptop that has Windows 7 32-bit and used the UPD 32 bits and the same symptoms occur.

    Any ideas because I hit a brick wall.

    Thank you very much!

    Looks like you can set up a standard port and print ok from a print server.  The UPD in the stream you describe will attempt to make multiple calls SNMP to determine the abilities of the printer, and those who are failing, causing the UPD to throw the error you see.

    Take a look at the network settings in the SAP.  Specifically, under Security, management of the protocols and the SNMP tab.  Watch to see if one of these parameters differ from other devices that work, like maybe SNMP is disabled on the YOA 4700n.

    Hi Vishwa, there.

    using JDev 12.2.1 to create fusion web applications means that you use ADF

    12.2.1 and you try to deploy this app on WLS 10.3 which

    knows nothing about ADF 12.2.1. This means that you must

    install and configure the ADF 12.2.1 libraries running on your application

    Server prior to deployment.

    Before that review certification ADF matrix to determine the

    version minimum 10.3 where you can run ADF 12.2.1-

    http://www.Oracle.com/technetwork/developer-tools/jdev/documentation/122-CERT-2708091.html#ApplicationServers

    However, you should check if installation 12.2.1 ADF will not

    installation of OBIEE break.

    Before you dig in fact ADF 12.2.1 installation can you pack

    your application developed in JDev 12.2.1 and deploy from the admin

    Console?

  • How do you communicate with the Apple Watch

    How do you communicate with the Apple Watch

    Hello!

    Welcome to the Apple community. I'm not quite sure what you mean when you say "communicate" with the Apple Watch, so I'll give you a few options that can respond to your request.

    (1) the Apple Watch supports Siri, just like the iPhone and the Mac. To apply, simply say "Hey Siri" while the wrist is triggered, and your watch will respond. Alternatively, you can hold the digital Crown and Siri will be activated. As soon as Siri is activated, you can ask him questions such as "what is the weather today" or "reminder", or "Let's start a workout."

    (2) you can manually send SMS via your Apple Watch by use of Siri, or opening the messaging app. That Siri send your messages, just say 'Hey Siri, send a text < name >' and Siri will open the Messages app and wait to talk to you about your message. If you want to move the Messages app manually, press the digital Crown and will take you to the home screen. In the home screen, select the Messages app (a green icon with a word inside bubble). Any existing message log must appear, and you can type on a given message log and choose to respond.

    (3) If you want to place a phone call using your Apple Watch, you can say "Hey Siri, call < contact name >". If you have several numbers for a particular contact, Siri will ask you what number you want to call. You can also you can present a more specific request like 'Hey Siri, call < contact name >, < number >' with the number favorite is 'work' or 'House' or 'mobile' etc. So the demand go something like "Hey Siri, call Barbra, House".

    If you are still at a loss, with regard to the types of orders that Siri will accept, you can always ask. Say 'Hey Siri, what can you do?' and she will give you a list of commands that she will answer to the.

    If all goes well, I addressed your question. If not, please provide a little more information and I'll do what I can to help you.

    Good luck!

  • Issues with the controller of Siri

    I got the last Apple TV since Christmas, and lately, it seems that I might have a problem with the controller of Siri. When you place your finger to use the contact surface, for that one click-much like the glass mini is not defined in law if that makes sense.

    Does not really affect the operation but is off-putting. If you want to just to click and press down, basically click twice on it records only one. He did not have it to begin with and has not been abandoned or anything - is always in perfect condition. Don't know if anyone has similar problems or if I have an error with mine?

    Sounds like it is damaged or defective for me

    Continue error message of "Unable to communicate with the printer." Even when connected by USB.

    Have reinstalled the software several times, checked the wireless (no problem), printed many pages of configuration directly from the printer.

    I keep trying to add the printer to my preferences. One thing is that it will only add like a scanner or fax, a PRINTER. It is also called Hello Scanner. Why can't I add as a printer?

    Now, it will not also let me COMPLETE reinstallation of the software, it freezes at the section add printer and I can't move forward. So frustrating...

    Help!

    Hi @PKahn

    It seems that the computer does not recognize the print driver.

    We will reset the printing system, repair disk permissions, add the printer using the driver and try to start a new search.

    Reset the printing system

    1. Click on the Apple icon ( ), then click on System Preferences.

  • VIX file in the user interface designer receives the data from the Web service application that communicates with the SQL server database

    I created the Web service VI ("Mt-insolacije.vi"), which has two terminals of the input string (FROM / TO) for the dates of arrival and exit of two data terminals (table 1 d) from database (MS SQL server). This VI communicates with the database with functions of the database with a DSN and SQL query appropriate palette. There are two tables with two data (time and Insolation) columns in the database.

    This VI works when you run in Labview 2010, but when I used it as VI in UI Builder it returns no data.

    Could you please help me find a solution. Is it possible to communicate with the SQL server database in this way or there is another way?

    Please help me ASAP!

    Thank you

    I found the solution problem is in the DSN. I've been using the user instead of DSN system DSN.

    It's important to create the system DSN if you want your VI of web service to communicate with the database.

    PS Please put feature bundle format timestamp and XY graph in the web user interface designer. It's complicated to trace data with datetime on X axis without them.
