Many instruments have a secondary GPIB address used for direct
communications to printers or whatnot. Ignore 1417 unless you're
wanting to talk to stuff attached to the instruments private GPIB
bus.

sure- the instrument is at 816 - you are pointing to 1416. It will error.

not really- point to 816. Just be sure to use the same name so that
your programs won't break.

     Question 1.
        I have a laptop with 1ea. NI PCMCIA GPIB card in it. It is attached to a HP 8753D network analyzer who's address is 16. When under I/0 Manager, I do a Find Instruments, it comes back with instruments found at "GPIB14   two instruments found at 1416 and 1417". It also comes back with GPIB32 with two instruments found
at 3216 and 3217. I create 2 panels using plug n play. One on the GPIB14 and one on the GPIB32 interface. They both seem to work fine. So they must be pointing to the
same instrument. But I don't know why it finds two interfaces when there is only one in the computer. Also I can seem to "remove the interface at 1417 and/or 3217" and the
programs still work fine. What would the 1417 address be point to?

    Question 2.

     I have several programs that were written in Vee 6.01 that talk to an HP 8753 Network analyzers and HP 3488 switches. The were written on a machine which had
a NI PCMCIA card installed and the address for the analyzers is "network_analyzer@1416". I am using calls to the AG875x plug n play driver.
    I just got an HP82357A usb to gpib cable. I installed it on the laptop and attached my network analyzer (address 14) to it. The laptop also has an NI PCMCIA card in it which is known to the system as "gpib0". The HP82357A configured itself as "gpib1" but when I go to I/O Manager and select "Find Instruments" it comes up as "gpib8" and it finds my analyzer at 816. When I run the program it errors out when it tries to talk to the plug n play panel pointing to 1416.

   Is there some easy way to re-direct all the calls to plug n play panels pointing to 1416 to 816?

It will not let me remove the "network_analyzer@1416" instrument and complains that there are plug n play calls to
this instrument and they must be removed before it will allow me to delete it. I tried to rename the "newinstrument@814" to "nework_analyzer@814" and it complains that
there is already an instrument named "network_analyzer".

    Ever since I have had VEE I have never understood just how I/O manager does it thing, but all of my programs have been ran on similar machines with pcmcia gpib
interfaces. I would sure like to know just what it is doing so I can use other configurations on other computers. Does anyone know of some documentation which explains
in layman's terms what all these address and interface names mean?

Thanks,

Q1: The 16 is the interface to the 8753 and 17 is the system controller
interface, the system controller talks to the display, printer, etc. So
you'll need to follow instructions on how to talk to the system controller.
Its kinda messy since you'll need to give the buss to the device at 17.

There also is a plug and play driver for the 8753. Check at the Agilent
site.

Q2: The HP82357A is a smart device, when you loaded it onto your machine I
think it allowed the existing controller to be the boss. There is some info
at Agilent on the 82357 when used with another GPIB. So I'm going to pass
on this one.

Al,

1) With the newer version of the Agilent I/O Libraries (and NI Libraries)
they have what is called pass through mode. In I/O Config is it listed as
"GPIB Using NI-488.2". There would be something similar in the NI
configuration software. This allows programs that were written using
HP/Agilent SICL to talk to NI cards. In the past, if you wrote a program
using NI-488 you couldn't use an HP/Agilent GPIB card, and this was true of
the reverse (a program using SICL couldn't use an NI card). I am sure on
your system the Logical Unit Number for this pass through mode is 32. VEE
also allowed communication to NI cards by directly calling the NI-488
libraries. In VEE the logical unit would be 14 or board ID 0, 15 for 1, 17
for 2, and 18 for 3. LU 16 was used reserved for direct VXI backplane access
such as embedded controllers and FireWire.

In short address 32xx would be use SICL but pass to the NI-488 drivers and
14xx would be call NI-488 drivers directly. I would recommend using the 14xx
address as the number of software layers decreases to get the NI hardware.

2) Have you tried going into instrument manager from VEE, edit the
configuration, and change the GPIB address and VXI plug and play address to
point to the new address? ALL direct I/O objects are tied to the instrument
configuration name and changing parameters (i.e. timeout, address, ...)
should not effect the objects at all.
