Try Galvant2 from here:

I just got the same adapter that Miti has and am also having issues. It seems to not be able to read the result of the "S" command even though I can when I use a terminal program. Were you ever able to figure this out?

Here's my debug log... Any tips?

As Miti said, you can try the custom "Galvant" versions on my web site. These are NOT fully functional. The Galvant firmware does not support binary transfers. This causes the calibration load/save to fail.

steve1515:
Thanks. It works!  :)

I've been re-writing the firmware for the Galvant adapter with a goal of full compatibility with the Prologix adapter. I expect to release it soon, since I only have a few things to work out. Hopefully this will make it so lmester doesn't have to keep different versions of his program and also so other people can use the open source hardware just like the Prologix in their other projects.  :)

In order to get my firmware to work the same as the Prologix, I'll need someone who has one to enter a few commands and send me the PuTTY log for review. I would do this myself, but I don't own a Prologix for testing... but that's why I bought the Galvant hardware.  ;D

Can someone with a Prologix please execute the following commands in the order provided with logging turned on and upload the file? I'm mainly looking to match certain command outputs and line endings for maximum compatibility.


--- Code: ---++ver
++addr 18
++addr
++addr 18 97
++addr
++eos 1
++eot_char 13
++eot_enable 1
++addr
++ver
++help
++eot_char 10
++addr
++ver
++eos 0
++addr
++eos 2
++addr
++eos 3
++addr
++help

--- End code ---

If PuTTY is used on windows, please use the following settings:

--- Code: ---Session -> Logging -> Session Logging = All Session Output
Terminal -> Implicit CR in every LF = OFF
Terminal -> Implicit LF in every CR = OFF

--- End code ---

One final thing I'm wondering...
When the Prologix is connected to the HP 3478A, if "++read" is sent, does the meter return the value continuously or only just a single read?

Thanks for any help anyone can provide!
I hope to publish the source code on GitHub for all to use once it's done.   :D

I just wanted to update here that I've released what I call version 6 of the firmware for the Galvant GPIBUSB adapter. This firmware is highly compatible with the Prologix command set. You can find it here: https://github.com/steve1515/gpibusb-firmware

This firmware allows the Galvant adapter to work with the regular version of lmester's HP 3478A control program. Binary read/write works as well, so the meter calibration can be read and written.
