Hey Luke,

thanks for your reply!

Yes, thats exactly the setup I use. The two computers are connected via Ethernet (but I also tried a connection using a cat5 crossover cable as this is recommended in the IviewX Manual).

The first thing I did was to check whether the single-PC Setup works properly. So I changed the Connection Settings in the hardware-communication menu both to local host adresses. This works fine with the provided example scripts for matlab and the connection was established.

For the dual PC Setup, I first copied the IviewSDK folder to the Stimulus PC. I changed the IPv4 adresses and the respective ports of the two pc´s at the hardware-communication menu as well as at the "Iv_connect" function which is also provided within the example scripts (but I don´t know whether you are familiar with those ones?).

Running the script results in an error Code "401" which is not further explained.

I also sent a "ping" from one Pc to the other to check whether the communication works in general. This also worked out.

Besides I have no other TCP/UDP/IP Toolbox installed. Maybe this could result in that particular error?

best regards and thanks in advance.

Hey Luke,

thanks for your Input and your thoughts. Those are definitely helpful and I´ll try to "apply" them as soon as possible.

Yes I ran the Debugger on that script and it turned out, that as a result of the iv_Connect_function there should be a value assigned to a variable, termed "ret_con". In my case, this is the number 401 which results in the error we talked about. A value of 1 is "necessary" to establish the Connection successfully.

Here is the respective part of the script:

%Connect to server

disp('Connecting to iViewX')

ret_con = iView.iV_Connect('IPadress1', int32(4444), 'IPadress2', int32(5555));

switch ret_con

case 1

connected = 1;

disp('Connection was successful')

case 104

msgbox('Could not establish connection. Check if Eye Tracker is running', 'Connection Error', 'modal');

case 105

msgbox('Could not establish connection. Check the communication Ports', 'Connection Error', 'modal');

case 123

msgbox('Could not establish connection. Another Process is blocking the communication Ports', 'Connection Error', 'modal');

case 200

msgbox('Could not establish connection. Check if Eye Tracker is installed and running', 'Connection Error', 'modal');

otherwise

msgbox('Could not establish connection', 'Connection Error', 'modal');

end

Besides I did not try to install the Iview SDK yet, because i thought this only works out with the associated Hardware/SMI Laptop, but i will also give this a try. Your idea concerning the TCP/UDP/IP Toolbox sounds very promising. If you don´t mind I would be glad to have a look at your example script!!

Nevertheless it´s good to hear that there are other researchers out there also struggeling with SMI-Equipment ;-)

best regards and thanks in advance

Hey Luke,

thanks again for your mail.

It finally worked out! I just had to again install the latest version of the Setup_iViewX_SDK.exe and now it´s perfectly running.

Thank you very much for your Support!

Best regards

Kilian

Hi Kilian,

where did you get the latest version of the Setup_iViewX_SDK.exe from? I seem to have similar problems, although with error code 100.

Cheers

Nico

Hey Nico,

I think I downloaded it directly from the SMI Website but I don´t know if it is the most current version of the Sdk. I´ll be at the lab on wednesday and verify that. I´ll send you a message (including the sdk, if it´s a more recent version than yours).
