  1. Knowing that others are designing without RS232/GPIB is the data I was looking for. Thanks. At this point I'm feeling fairly confident that I won't have to concern myself with any GPIB protocols or even VISA. I think by using one of the adapters I've since run across will take care of all of that - and I sure hope that really does hold true. I will just write my driver to deal with sending / receiving over Ethernet or USB. Yeah. There aren't too many SCPI commands I need to interpret so it shouldn't be too bad. I thought that all devices HAD to implement ALL the 488.2 commands, but as I look at more devices I see that many actually don't seem to implement the entire 488.2 protocol but rather just what they need. I will take the same approach and just implement what I neeed of the 488.2 protocol. Certainly makes my life easier! Thanks again for taking the time to respond to my post! -Scott
  2. Mark, Thank you for your reply. I think I wasn't quite clear here. My PC is the device, not the controller. Being the actual device I want to concentrate on device functionality and not on learning any more communication protocols than I have to. I know I will have to implement a SCPI parser at a minimum. With that said, my questions really are: 1) Do I need to implement anything other than SCPI over (TCP/IP) ethernet or USB to be a viable product in the marketplace? 2) Could I just use a GPIB -to-Ethernet or GPIB-to-USB adapter to connect my device to an existing cluster of devices that are connected via GPIB? 3) Another question: Are you aware of an availableJava language SCPI parser? I'm just now trying to get up to speed on instrumentation products / protocols, etc. , so if my questions aren't precise forgive me. Scott
  3. Hi, I'm posting this question here because I don't know where else to post it. I want to implement a new device on my PC to take some measurements. Remote control will be via SCPI so it can play in connected environments. From my research it appears to me that I can just send SCPI text out over the USB comm port or Ethernet. If the device needed to play in a GPIB connected environment then all I would have to do is purchase either a USB - to - GPIB, or Ethernet -to- GPIB connector. Is this a correct assumption on my part? I want to make sure there is not another layer of software that needs to be implemented. -Scott
