Programming via LAN 5

Agilent VISA User’s Guide 125

Remote USB Interface (USB VISA LAN Client)

A remote USB interface can use only the SICL-LAN protocol. It can

communicate with USB devices attached to a remote PC running the

Remote IO Server software.

Note that if you have defined a VISA alias for a USB device on the

remote I/O server, you must either define the same (or another) alias for

the remote USB device on the client PC, or use the full USB resource

string. Alias definitions are not shared between the remote I/O server

and the client.

Addressing a Session Using a Remote Interface

In general, the rules to address a remote session are the same as to

address a local session. The only difference for a remote session is that

you use the VISA interface ID (provided during I/O configuration via

Connection Expert) that relates to the remote interface.

The following sample shows one way to open a device session with a

GPIB device at primary address 23 on a remote PC that is running

Remote IO Server software. A remote GPIB interface has been

configured at GPIB2 to communicate with that machine. See Chapter 3,

“Programming with VISA”, for more information on addressing device

sessions.

ViSession defaultRM, vi;.

viOpenDefaultRM(&defaultRM);

viOpen(defaultRM, "GPIB2::23::INSTR", VI_NULL,

VI_NULL, &vi);

viClose(vi);

viClose(defaultRM);
