How to control PCI-6602 TTL pulses from remote computer?

[Kai-Mei]

I have an instrument which is controlled by TTL pulses I send from a PCI-6602 board. I am able, using DAQ-mx functions, to control it with the computer that the board is installed in. However, I need to now control it from another room and another computer (with Labview 7.1 as well).

I have tried the following
1) Looking for the remote system using the VISA server in measurement and automation. Doing this I can see the serial/parallel ports and GPIB instruments on the DAQ board computer but not the DAQ board!
2) Doing call by reference functions and accessing subvi's that are on the DAQ board computer. I am able to receive communication from the laser on the input channels on the DAQ with the call by reference function but not send TTL pulses! The program believes it is doing so, but my laser (and oscilloscope) disagree unfortunately.

Please help! I really do not car how I initialize the counter board (needs to be initialized to single pulse mode) and send the pulses- just as long as it works.

Thanks

Hello Kai-Mei,
You may wish to consider using remote panels. The remote panel feature in LabVIEW allows you to remotely control your LabVIEW application over the Web -- with no additional programming. You can find this feature under Tools>>Web Publishing tool. When you have your final VI saved, you can publish it to the web so that you can view or control the results from a remote computer. All you need to do is save the htm file to your labview\www directory and then you can control it from a remote computer by typing http://machine–name/vi-name.html where the machine-name is the IP address of the computer running the program and the vi-name is the name of the VI you want to run. When you can see the image of the front panel in your web browser just right click and request control. I hope this helps!
