Hai every one.
I am writing the code to acquire the data from Bruel & kjear controller hardware.
This hardware and my pc connected through LAN cable.

Transmission protocol : tcp/ip

code :
t = tcpip(' 10.10.10.11');
fopen(t)

After setting all the network connections, i executed my code then it display the error

ERROR : connection timed out : connect
so, please give me suggestions for how to retrive the data from Hardware controller.

You probably need to specify the destination port number.

Hello,

I assume that the controller hardware listens on a specific port. By
default, the remote port will be 80 commonly used by web servers. A more
complete version of your same command would be:

t=tcpip('10.10.10.11', 80);

You can test if the controller is listening on port 80 using your system's
telnet command.

>> ! telnet 10.10.10.11 80
Trying '10.10.10.11'...
telnet: Unable to connect to remote host: Connection refused

This indicates there is nothing to connect to on port 80. The controllers
documentation may have more information about which ports it listens to.
