For my bachelor degree im designing a sort of converter. I was wondering if anyone did that. Close Wizard.

While so much in the tech world is very fast to change to newer cheaper and better technology, GPIB remains surprisingly entrenched in the test and measurement arena. It seems to be the belief of most of the Test and Measurement community that in time, Ethernet, often with an isolated network will prevail as the dominant interface between instruments and PCs.

Structured Programming — Structured Programming is a programming paradigm making extensive use of subroutines and block format structures. It follows through to many higher-level languages improving troubleshooting, and maintenance of the software. Proper use of structured programming facilitates among other things, easy transition from legacy protocols and busses to more current technologies.

Having structured programming in place that is modular and easily maintainable will enhance any system that is not already doomed to a fixed lifespan. Having seen the changes over the years, it is not likely that the changes in instruments or computer busses will come to a halt soon. VXI and PXI — Two other bus structures for communication with instruments are of note here as well, PXI and VXI, both of these are substantially instruments without user interfaces, built on the architecture of existing computer bus technology.

These instruments must live in a host computer or bus expansion chassis. They cannot stand alone like the usual benchtop instruments but rely on the host computer to operate. They are often implemented when instruments are dedicated to a task and are not really required to have front panel controls and displays.

There can be notable cost and space savings by the integration with the computer as the sole user interface or control mode. In this case, Ethernet can easily control the Thermal conditioning system while other instruments still enjoy the benefits of the integrated system. The arduino is meant to use a character buffer, but maybe that is for sending only. It looks like I may have to write my own code to send and receive the rs on the PC and to implement my own handshaking scheme to avoid any overrun.

Perhaps I have to add my own checksum to confirm that data was sent reliably. It has to be possible as the IDE uploads the code to the Arduino without a problem, but it is disappointing to see that the standard Serial library is so bad. I have the oscilloscope out already to try and see what is happening and I will soon probably have to get the logic analyzer - just for the most basic possible RS communication using standard Arduino function calls! If someone has managed reliable two way communication with an Arduino and has some advice, let me know.

Quote from: amspire on December 15, , am. Martin, Thanks a lot. It looks like the Arduino behaves well. I should be able to complete my serial routines now and start testing. Richard, How did you go with this project? If people are still interested: this is about as low-cost as you'll get. Its really not that difficult hardware.

This weekend i wrote the software and used the prologix command set as a way to make it compatible with some software. I have tested it with my HP A and my Solartron and they both function well with it. I still have a few features i need to add to make it full prologix compatible its not yet recognized by the Prologix configurator.

Not sure if i should get some boards for this made up and release it to the wild. Overall i think not a bad weekends work. Bread boarding it. There are More commands than listed with in the screen shot, just haven't got round to updating the help command yet.
