6.2.3.3 Remote Control over LAN using Socket Communication
This chapter provides an example on how to establish a remote control connection
over telnet protocol and a simple sockets-based program example that can be further
developed.
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 SMC, start the telnet program.
2. Enter the access string to connect to the instrument and confirm with ENTER.
The access string is composed of the open command short form) and the socket
address. The socket address is a combination of the IP address or the host name
of the R&S SMC and the number of the port configured for remote-control via tel-
net. The R&S SMC uses the port number 5025 for remote connection via Telnet.
Example: o 10.113.1.150 5025
The connection to the instrument is set up and you can send remote-control com-
mands.
3. Even if the cursor is not visible on the screen, enter blind a remote-control com-
mand and confirm with "Enter".
