[Linux-gpib-general] Problems with GPIB-pcIIa card and ibtest

[Giacomo I. <gi...@in...>]

I just installed the linux-gpib.3.1.93 drivers and am trying for the 
first time to interface to some instruments through a NI-PCIIa card on 
an ISA slot.

Using ibtest I can send an interface clear apparently with no errors:

gpib status is:
ibsta = 0x8100  < ERR CMPL >
iberr= 0
EDVR 0: OS error

ibcnt = 0


but whenever I try to write a string to a device I get a Bus error:

gpib status is:
ibsta = 0xc100  < ERR TIMO CMPL >
iberr= 14
EBUS 14: Bus error

ibcnt = 0


Do you have any idea of what the problem could be?

Here is my gpib.conf file:

interface {
   minor = 0
   board_type = "pcIIa"
   name = "ISA"
   pad = 0
   sad = 0
   timeout = T3s
   eos = 0x0a
   set-reos = yes
   set-bin = no
   set-xeos = no
   set-eot = yes
   base = 0x02e1
   irq  = 7
   dma  = 3
   master = yes
}

device {
         minor = 0
         name = "k230"
         pad = 13
         sad = 0
        	eos = 0x0d
         set-reos = no
         set-bin = no
}

Actually, you are getting an error.  That EDVR should really be an EARG, =
you=20
are apparently trying to do an interface clear on a device instead of a b=
oard?

Are you sure your base address and irq are correct?  It could also be som=
e=20
problem with your device, it is timing out while trying to send the comma=
nd=20
bytes to address the device as listener.

- --=20
