A bit further to Ulrich's point... one area where I had some problems using serial/gpib converters in the old days, and I think that at least early versions of the Prologix USB unit suffered from, is talking to multiple instruments off the same GPIB controller. I never found a satisfactory way

Good points... and pretty much in line with my thinking. Based on the comments here, I'm strongly leaning toward the LAN version now. I'll definitely have a closer look at the KE5FX toolkit, there are some very interesting applications there. Thanks everyone for your input. Looks like I have a

Re: [time-nuts] Prologix GPIB-USB vs. GPIB-LAN

Yes, it should be pretty simple, even in shell. I have some noodle-scratching to do on retrieving graphical output from instruments though. I'm not terribly concerned about being compatible with other hardware, as long as the hardware I get won't be left useless or anchored to an archaic OS becau

Re: [time-nuts] Prologix GPIB-USB vs. GPIB-LAN

If you are willing to (or want to) write your own software, than the Prologix Ethernet adapter is the way to go. I've done it in PERL under Solaris and IRIX without any trouble. Just open a socket connection on port 23 and send over text commands. Very easy. MUCH easier than using NI products.

I looked at the Prologix stuff long and hard BUT it is something of a dead end. I didn't want to write new software and I have some existing apps that I use. I found an NI gpib-enet ( http://digital.ni.com/public.nsf/allkb/D2

If it's about "Ethernet vs. USB" queston I would always suggest Ethernet. - With any kind of equipment in question! Ethernet is simpy much better: you don't need device drivers, it works with longer cables (over 10 times longer than USB), it's routable, you can use it remotely (VPN), you can t

I have a GPIB-LAN, and it works. You basically telnet to it and issue commands either manually or via software. It works with EZ-GPIB without any trouble. It's extremely easy to use. That being said, it is not a substitute for a GPIB card from NI. I wrote a spiffy software program in VB to pul
