HP-IL and EMU71

[hesc]

Dear Christoph,

You are completely right: it is a good idea to read all manuals and get a complete understanding of the concepts behind real and virtual HP-IL operations. However, if one is rather new to this kind of interfacing one will meet several obstacles to solve. Furthermore it is quite a search for all the available information scattered over the web. So I am quite happy with the help of all of yours to help me a step forward...
So, thank you for all the nice work on EMU71 and related software and for the manuals, information on documentation and video presentations to study the subject any further. In the meantime I also found the manual on HP-IL operation for the HP71.

Kind regards,
Henk

Dear Sylvain,

That was a typing error in my mail. Sorry for that...
In fact, I programmed a loop
10 FOR I=1 TO 5
20 DISP DEVID$(I)
30 NEXT I
and got your list, except for I=5 I got a blank.

In the meantime, I discovered that the menu of ILPer gives an HP-IL Device Info with the same information, but indeed, DEVID$(5) is not available.
So, the problem has not been solved.

Thanks again for your thinking along...

Kindest regards,
Henk

I have connected my 3468A, DEVAID(5) return -1 and DEVID$(5) returns "HP3468A", so it work on my side.

It is a static list of the devices ILPer it provides and not of the devices in the loop or connected to it.

TCP/IP configuration for all software


RESTORE IO followed by DEVID$(5)


In the HP-IL Scope section you see the low level HP-IL commands/messages send over the loop.
The ILPer Scope only show messages coming from the controller in this configuration.

AAU     RFC     
AAD 01          (the following AAD messages are not seen by the HP-IL scope)

DEVID$(5) and the peripheral reply "HP3468A"+CR

Here is a more complicated diagnostic setup that insert a ILScope before and after the PIL-Box.

Dear Sylvain,

From your screen dump I could see that the out port of the HP-IL interface setup of ILPer was 60002. I remember that I changed it according to your subscription to that value, but for some reason it had the original value of 60000? Putting it back to 60002 solved the problem: DEVID$(5) returns "HP3468A"! See also my screen dump.
Thank you again for your patience...

Kindest regards,
Henk

Great! I am happy that you figure it out, have fun!
