Switching sockets http request does not work

[Faneduru]

I have a Lan Controller (HW:1.2 SW:2.59 S/N:6446) which works well but I cannot switch the sockets (http request) like it is written in the documentation. I mean if I write: user:password@192.168.1.100/outs.cgi?Out=2 it just returns the status of the Out sockets (11111) without changing their status. Of course I use the correct user and password and the right IP (and port)...
Is it something to be configured in order to make it work from this point of view?

Thanks in advance!

proper user:password@192.168.1.100/outs.cgi?out=2
"out" lower case letters

Thanks Tomek!
In this way it works!

I copied the text from the manual. I did not imagine that it is case sensitive. Of course I eliminated all unnecessary extra spaces, but I never thought that the capitals may disturb the result. Especially since it returned the sockets status...
I am afraid that even if it would work sometimes when I should try it in lower case, I could not understand that it is due of that...

Thanks again!
P.S. Such a modification in the pdf manual would be good to be done and appreciated...
