5 Programming via LAN
as if it were connected to a local interface. If, for example,
the GPIB2 interface is configured as a remote GPIB interface,
a program controlling the devices GPIB2::5::INSTR and
GPIB2::7::INSTR would not be aware of the fact that these
devices are actually connected via LAN and not to a GPIB
interface connected to the local machine.
See the Agilent IO Libraries Suite Online Help for specific
information on configuring remote interfaces.
Remote Serial Interface (ASRL VISA LAN Client)
A remote serial interface can use only the SICL- LAN
protocol. A remote serial interface can be configured to use
the serial port on the Agilent E5810 LAN/GPIB gateway or
the serial ports on a PC running the Remote IO Server
software.
Remote GPIB Interface (GPIB VISA LAN Client)
A remote GPIB interface can use both the VXI- 11 and
SICL- LAN protocols. Typical uses for remote GPIB interfaces
are with LAN/GPIB gateways (e.g. Agilent E5810), PCs with
GPIB interfaces that are running a LAN server, and VXI- 11.2
LAN- based instruments.
A remote GPIB interface can only be used to communicate
with VXI- 11.2 (GPIB Emulation) devices. This is because the
VISA GPIB interface type requires a primary and (optionally)
a secondary address when communicating with a device.
VXI- 11.3 devices do not support the concept of a primary
address, so they cannot be accessed with a remote GPIB
interface.
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.
