●
Uses a single IANA registered port (4880), which simplifies the configuration of fire-
walls
●
Supports simultaneous access of multiple users by providing versatile locking
mechanisms
●
Usable for IPv6 or IPv4 networks
Using VXI-11, each operation is blocked until a VXI-11 instrument handshake returns.
However, using HiSLIP, data is sent to the instrument using the "fire and forget"
method with immediate return. Thus, a successful return of a VISA operation such as
viWrite()
guarantees only that the command is delivered to the instrument's TCP/IP
buffers. There is no confirmation, that the instrument has started or finished the
requested command.

Socket communication
An alternative way for remote control of the product is to establish a simple network
communication using sockets. The socket communication, also referred to as "Raw
Ethernet communication", does not necessarily require a VISA installation on the
remote controller side. It is available by default on all operating systems.
The simplest way to establish socket communication is to use the built-in telnet pro-
gram. The telnet program is part of every operating system and supports a communi-
cation with the software on a command-by-command basis. For more convenience and
to enable automation by programs, user-defined sockets can be programmed.
Socket connections are established on a specially defined port. The socket address is
a combination of the IP address or the host name of the instrument and the number of
the port configured for remote-control. Typically, the products of Rohde
&
Schwarz use
port number 5025 for this purpose. The port is configured for communication on a com-
mand-to-command basis and for remote control from a program.

LAN web browser interface
The LAN web browser interface allows for easy configuration of the LAN and remote
control of the R&S
ZNL/ZNLE without additional installation requirements.
The instrument's LAN web browser interface works correctly with all W3C compliant
browsers.
Via the web browser interface to the R&S
ZNL/ZNLE you can control the instrument
remotely from another PC. Manual instrument controls are available via the front panel
simulation. File upload and download between the instrument and the remote PC is
also available. Using this feature, several users can access
and operate
the R&S
ZNL/
ZNLE simultaneously. This is useful for troubleshooting or training purposes.
