Good job! I've read other good experiences about the Beiming. I finally wound up buying a Prologix Ethernet adapter.

Re: [time-nuts] linux-gpib working on a RasPI
Hi Mark, Well, his subject is linux-gpib, and the gold anodized clone simply will not work with the linux-gpib drivers. I think I drove the developer batty trying to get it to go, but it's not going to happen without a complete rework of the code. I don't know whether that will ever take place, either. OTOH, if you are using the Agilent driver, it seems to work well. By this I mean that under Windows XP, Agilent's Connection Expert was able to send and receive commands and data to my HP units. It was also able to do the same over the network when Connection Expert was running in a Windows Virtual Box on my Debian system and I was running XP natively on a separate machine as the client. I thought about trying to just run through the network with a Linux client on the host, but I was unable to get information on how to get that configuration to run from the Linux side, so I just gave up. It might have happened eventually, but I just wasn't in the mood to drop my project to spend weeks on figuring out how. With the Prologix unit, I had a homebrew client library (in C) up and running well enough to make me happy the day it arrived. I do not use NI-VISA, and trying to figure out that mares nest just left me completely mystified. I'm a good enough C programmer to do the things I need once I have connectivity and a simple interface. No connection to Prologix, etc, etc, etc. Bob - AE6RV From: Mark C.

Re: [time-nuts] linux-gpib working on a RasPI
I've got a question for you Hal. We can take it offline if it's more than a response or two. I opened two sockets to the adapter in one program and found the same socket id. OK, that tells me that I have to address each device before sending commands to it, rather than having a separate socket id. And it makes sense. But how does it work when I have multiple programs wanting to access different devices? Am I doing to need to put some lock code in so that the adapter is globally locked to one program while it sending or receiving to/from a device to prevent the two programs stepping on each other? For example, I've got 2 counters and a voltmeter. It's no stretch to think of two different tests, or even three using those instruments separately.

Re: [time-nuts] linux-gpib working on a RasPI
Prologix Ethernet controller supports only one client connection. A second connection will disconnect the first one. Make sense, since a GPIB bus can have only one (active) controller. Currently, the controller does not allow a client to lock it exclusively, since that opens up the issue of orphaned locks due to crashed clients, and so on. One solution is to develop a piece of host software (a controller server, if you will) that acts as the (only) client to the controller, and to which the various test programs then connect. This software can arbitrate access to the controller. For further help, please contact us off-list.
