The following is an email I sent to Prologix, after discovering some “idiosyncrosies” with it’s initial setup. I think it has some useful info:
“I’m very excited by the gpib-to-ethernet adapter. But there’s some weirdness in getting them to work:
Initially, the adapter shows up at ip address 0.0.0.0. This is NOT a legal address, and most “standard” ip-protocol software refuses such an address. Instead, please choose a canonical default address… say 192.168.1.x …or anything typical AND legal.
Even worse, the initial port seems to be a random number, not 1234 or a typical open port. All of the computers I use nowadays have firewalls running, and only after multiple days of struggling to “see” the adapter, did I try turning off the firewall…. There it was, spewing out udp packets! Please change the “random port” to 1234, or better yet, a typical open port #.
I am OSX as much as possible, and while I managed to run your netfinder and configurator under an emulator, your software could be implemented EASILY with a web-server (which would also use port 80)… and therefore platform independent. Look at ANY hub, switch, serial server, etc on the market today; they ALL follow this standard.
I’m still eager to put my gpib-enet adapters to use, but your software engineers made a couple very poor decisions instead of following established standards. I welcome a response, but please don’t put me on any mailing lists."
No public wish lists :(
