Hello Steven T,

If the NI-488DDK 1.1 could use for  TNT5002 pci-gpib?

Hello all,

      If the NI-488DDK 1.1 source code could be used for TNT5002 pci-gpib?

I found it can be used in the TNT4882 pci-gpib developing,but the regesters between tnt4882 and tnt5002 different.

Thank you!

Hello clover,

The NI-488.2 DDK allows you to work with a PCI-GPIB board from National Instruments.  These boards are controllers, so they can talk/listen/control the bus.

The important distinction here is that the PCI-GPIB does not come with a TNT5002.  It comes with a TNT5004, which is a different chip.  Please comment on what you are using.  In all of your posts, you mention both the PCI-GPIB as well as the TNT5002.

Thanks,

Steven T.

Hello Steven T,

First,thank your help for so long time!I drived the pci-gpib board based on tnt5002 with the datasheet and your help,now,it can transfer data which less than 32 bytes with usb-gpib on the  pc.I am not use the NI-488DDK... .But I still have a problem,I don't known how to response to controller's *IDN? command.Need I receive the string "*IDN?" and use the sending code to response ?

Thank you very much!

Hello Steven T,

With the last post,I read BSR,the value is 0x30,and datasheet said "TNT5002 can't assert ATN#,IFC#,or REN#",I know it's mean that tnt5002 is not a controller.

Steven T,

I believe myself much more.It will be software first receive the 488 command such as *IDN?,RST,*OPC? and response to controller for it.Because anything else,data or command,which will write to GFIFO.The tnt5002 doesn't known the differ between data and the command.

Is it right?

Thank you!
