Configuring I/O Interfaces
Configuring LAN Interfaces
n iopen("lan[machineName]:hpib7,1") will use the configured
default protocol. If AUTO is configured, SICL-LAN protocol will be
attempted. If that is not supported, VXI-11 protocol will be used.
n iopen("lan;auto[machineName]:hpib7,1") will
automatically select the protocol (SICL-LAN if available and VXI-11
otherwise.)
n iopen("lan;sicl-lan[machineName]:hpib7,1") will use
SICL-LAN protocol.
n iopen("lan;vxi-11[machineName]:hpib7,1") will use
VXI-11 protocol.
The LAN Client also supports TCP/IP socket reads and writes. To open a
socket session, use iopen("lan,socketNbr[machineName]").
For example, iopen("lan,7777[machineName]") will open a socket
connection for socket number 7777 on 'machineName'.
When you have configured VISA LAN Client interfaces, you can then use
the interface name specified during configuration in a VISA viOpen call of
your program. However, the LAN server does
not support simultaneous
connections from LAN clients using the SICL-LAN Protocol and from LAN
clients using VXI-11 (TCP/IP Instrument Protocol).
There are three LAN servers that can be used with VISA and SICL: the
E2050 LAN/GPIB Gateway, an HP Series 700 computer running HP-UX,
or a PC running Windows 95/98/Me/2000/NT. To use this capability, the
LAN server must have a local GPIB interface configured for I/O.
