NTP and TET servers -- Linking EEG and eyetracking

[Caitlin]

Hi there,
I've also posted this to the PST forum -- trying to cast a wide net! Appreciate your ideas:

I am installing our new eye tracking system (Tobii TX300). I'd like to use a one-computer system (i.e., 1 computer to both run EPrime and Tobii). This would be ideal for us, because we plan on also sending events from EPrime 2 -> NetStation 4.4 (EEG acquisition software). I've run into an interesting conundrum: When I try to run the Tobii Eprime samples, it immediate throws an error, asking for the NTP server. Now, this is without the NetStation package being added to the EPrime experiment. If I open the Mac and start a NetStation session, this permits the EPrime to start the experiment (no NTP error). However, the TET server throws an error:

Routine: TET_Connect()
Error Script: 2
Error Text: Failed to communicate with server. Disconnected.
TET support will now be disabled.
The eye tracking connection will be closed and further errors will be suppressed.

I'm a baffled. I've entered the correct server information (serverID.local.) is entered into the IP Address/Name box for the TobiiEye Tracker Device Properties. The other options I left to the default (Port = 4455, Sync mode=Local, Max count =4096).  I've pinged the server from the command prompt, and it the PC and Tobii are connected just fine. So this all comes down to a few questions:

1. Why is EPrime requiring the NTP server when running an experiment without the NTP package or devices? Is there a clock setting that needs to be changed after adding the Tobii EPrime Extensions pack?
2. What is going on with the TET server? I'm out of ideas for troubleshooting. I've tried restarting the systems in different orders; I've double checked the serverID values, successfully ping the Tobii before running experiment, etc. 

I really appreciate your help! cheers,

I have the same problem. I wonder if you could share how you solved this problem. I would really appreciate it. Thank you very much.

Hi Caitlin, 

I'm running into a similar problem. I know this occurred a long time ago, but do you remember how you fixed it? Thanks!

Take care,

Hi, 

 I had a similar issue with the same error. Instead of entering in the Tobii serial number in the IP address, try entering the IP address for the Tobii eye tracking monitor instead. At least in our lab set up (TT120), the Tobii computer and Tobii monitor each had a separate IP address. For some reason the local connection via entering in the Tobii serial number did not work, but once I entered in the IP address for the monitor/eye tracking component it finally connected and TET_Connect() was able to work.

Hi Diana, 

Our lab group is having a similar issue. How did you find the eye tracker's IP address? We're a bit stumped.

Thanks,

Brittany

I had dealt with this problem a while ago(unfortunately in another lab, so I can't check the computer settings now). I remember that at some point it was necessary to install Bonjour because this might be used for communcation with the eye tracker. Did you try this already?
