Dear All, I have a 54831D O-scope and for now the fast way to communicate with it is via Rs232 port. I have a NULL MODEM cable that I tested it between two computers and it works but I tried to send commands to the O-scope through the RS232 port but no answer from it. Is the O-scope has a working RS232 protocol for exchanging commands? because the manual says the port is only used for printer etc .... ?

I use Ubunto Linux as OS in the PC box.

Thank you, rachid

RS-232 is not a supported method of controlling an Infiniium Oscilloscope. LAN and GPIB are supported. USB is supported on newer scopes, but I'm not sure the older scopes ad that capability.

  Dear Al, First of all thank you for your clear answer!. Yes I believed it because the user prorammer's guide just mentioned GPIB and LAN communication protocols to talk to the O-scope. Now I am ordering a GPIB-RS232 converter box from NI to use RS232 directly from my PC box instead to buy to a GPIB card. We have RS232 C code ready so just use it with the converter box.
  
  For LAN I will discuss it with you and is better to create a new thread with new title so that it will be easy later to search for it in the archive.
  
  Thank you Rachid

Rachid,

LAN is a much better solution, and control from Linux is not too hard. I would recommend that you look on the Agilent website, first, though. There is a whole set of Application Notes on instrument control through LAN. A good place to start is to search on "Linux" on the main Agilent web page (www.agilent.com).

  Al, As you started here in this thread to discsuss LAN so I continue here. I already worked with low level sockets programming and can deal with it but as you said there are ready LAN routines in Agilent user programmer's manual and also have the files in my computer. The only thing that block me here is the O-scope I get it a used one and it has windows 98 on it and it seems it does not recognize our LAN, I tried to follow what they said in the manual to setup the ethernet: going to properties etc .... but I did not succeed to connect the scope to ethernet. Probably windows version is old and did not has some drivers .....
  I think I should install windows 7 for example? is it risky to overwrite things or it can be done?
