Control a TDS3032b over tcp/ip from LV602 MAC OS9x? It works from Win 2k.

[lvguy]

I am attempting to control a Tektronix tdsd3032b osciloscope via tcp/ip (gpib interface is optional) from a Mac OS 9.x running LV 602. Visa has not been able to connect to the instrument whereas the same vi works well from a PC Win 2k with LV 602. Does VISA has limitations on Mac platform?
Thanks for all help.

NI-VISA on Mac OS 8/9 does not support TCPIP, nor will it in the future. However, when LabVIEW releases on Mac OS X, you will find that NI-VISA 3.0 will support TCPIP there. That part of the NI-VISA code base is basically the same as on Win32, so it should work seamlessly.

For Mac OS 8/9, you will need to use GPIB for that instrument. By the way, some Tek scopes also support serial communications, which NI-VISA on Mac OS 8/9 does support. That might be another option for you.
