Setting Up a Remote Control Connection over LAN Using Socket
Communication
This section provides an example on how to establish a remote control connection over
Telnet client and a simple sockets-based program example that can be further devel-
oped (see also
Chapter A.2, "Telnet program examples"
The telnet client transmits information unencrypted. Therefore, for sensitive information
we recommend that you use a client which supports secure protocols, like SSH.
In the following example, we assume basic knowledge of programming and operation
of the controller. You can find information on the interface commands in the corre-
sponding manuals.
Setting up a Telnet connection
To control the software, only a Telnet program is required. The Telnet program is part of
every operating system.
1. To establish a Telnet connection with the R&S
SMBV100B, start the Telnet pro-
gram. Enter the socket address.
The socket address is a combination of the IP address or the hostname of the
R&S
SMBV100B and the number of the port configured for remote-control via Tel-
net.
Tip:
The R&S
SMBV100B uses the port number 5025 for remote connection via
Telnet.
The connection to the instrument is set up and you can send remote-control com-
mands.
