debug serial comunications

[Joju]

Hi all;

I have a aplication which comunicates with a lot of peripherics with serial interface rs 232 or 485, and some times I have several errors of comunications, the source code has been successfully debuged, but I don't have the security about the real comunications, I nedd some aplication or a way to debug on line or off line, the traces of comunications in every port.

some one know some aplication or function to debug the serial comunications when the labview aplication is runing????? better under Labview????

When you have communication errors, are they errors where the data is wrong or where there is a hardware error? What kind of serial hardware are you using, actual serial ports, usb - serial adapters ? As to means to troubleshoot, there are protocol analyzers that can monitor port activity, there is NI Spy, usually installed when NI-Visa, etc. installed.

I use a lot of types, depends of the peripheric, the most avitual is a multiserial board, but I use also USB.

Like LV_Pro says, you can use NI-Spy. You should already have it installed. It is kind of like wireshark for your devices.

Thanks, the NI-spy is enough, at the moment..........
