Hello all,
I am trying to use a program that was sent to me by a collaborator to control 2 KD Scientific syringe pumps using LabVIEW. The pumps are connected to a Windows 7 computer via a phone line attached to the pump, which is then connected to an RJ11 to D-type RS-232 converter. A Hawking Technology RS-232 to USB converter cable connects this converter to a USB port on the computer (this is because our computer only has 1 serial port but we have 2 syringe pumps). This is the same set-up my collaborator was using and it worked with no issues.
The problem arises when we try to control the syringe pumps with the LabVIEW program. We have drivers for both the Hawking cables and KD Scientific syringe pumps installed on the computer, but our computer only recognizes that the cable is plugged in--it does not recognize the syringe pump as a "device." We can run the LabVIEW program, but essentially nothing happens. When we press "stop," we get an error message that says "Error 1073807202 occurred at VISA Open in KD Scientific 2XX series initialize vi." I believe this means that the computer/LabVIEW is not able to communicate with the pumps even though we have the drivers installed and in the same folder as the program.
I am attaching the program we are trying to run (it is Version 2, it includes drivers for the syringe pumps), the driver we installed for the cables, as well as a screen shot of the error message. If anyone knows of anything we can try it would be much appreciated. The author of the program was at a loss since it worked just fine on his computer.
Thank you in advance!
