''gpib-modules-source'' n'est pas nécessaire car il ne compile pas avec un noyau > 2.6.8.

Modifier le fichier ''/etc/gpib.conf'' pour ajouter le device et éventuellement la carte :
{{device {
minor = 0
name = "7150plus"
pad = 16
sad = 0
}
}}

puis

{{$ sudo gpib_config}}

Test du fonctionnement
{{$ cd examples
sudo ./ibtest
Do you wish to open a (d)evice or an interface (b)oard?
(you probably want to open a device): d
enter primary gpib address for device you wish to open [0-30]: 16
trying to open pad = 16 on /dev/gpib0 ...
You can:
w(a)it for an event
write (c)ommand bytes to bus (system controller only)
send (d)evice clear (device only)
change remote (e)nable line (system controller only)
(g)o to standby (release ATN line, system controller only)
send (i)nterface clear (system controller only)
ta(k)e control (assert ATN line, system controller only)
get bus (l)ine status (board only)
go to local (m)ode
change end (o)f transmission configuration
(q)uit
(r)ead string
perform (s)erial poll (device only)
change (t)imeout on io operations
request ser(v)ice (board only)
(w)rite data string
: w
enter a string to send to your device: G
sending string: G

gpib status is:
ibsta = 0x2100 < END CMPL >

ibcnt = 2
: r
enter maximum number of bytes to read [1024]: 34
trying to read 34 bytes from device...
received string: '+25.65000 DEGC

!! Python

Un programme Python qui fait la même chose que ci-dessus :
{{from Gpib import *
m = Gpib("7150plus")
m.write("G")
print m.read(17)
}}
