Hi, everyone:
I'm trying to connect a GPIB device via LINUX-GPIB.The driver for NI GPIB card had been setup successfully.When testing with "ibtest" ,I got the erro:
[root@localhost etc]# 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]: 3
trying to open pad = 3 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 contro!
ller 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: :CHANnel1:CURRent 0.5
sending string: :CHANnel1:CURRent 0.5
gpib status is:
ibsta = 0x8100 < ERR CMPL >
iberr= 0
EDVR 0: OS error
ibcnt = 25
Is there anything I missed?
