The Noldus network communication protocol N-Linx is used for communication between The Observer XT and other Noldus IT software programs like MediaRecorder and external programs like BIOPAC AcqKnowledge, Tobii Pro Studio, Tobii Pro Lab, Tobii Glasses software, and Bitbrain EEG acquisition software. All programs communicate with The Observer XT using N-Linx Server.

For details on using N-Linx for communication between The Observer XT and other software, see the Reference Manual - N-Linx, or the technical note of the program to control.

Connecting The Observer XT with N-Linx Server

1. Select Use N-Linx Server to connect with other applications.
2. In the N-Linx Server address field, enter the name of the computer with N-Linx Server. You can also enter the IP address, but the IP address of the computer with N-Linx Server must then be fixed.
3. In the N-Linx Server port field, leave the default port number 5672 unless this port is in use by other programs. You must enter the same port number for all N-Linx components.

Using N-Linx with Your Own Software

N-Linx can also be used to control your own software. For example, to start and stop your own application with The Observer XT, or to import data from your own software in real time into an observation. Consult Noldus support for options and documentation on how to work with the N-Linx Software Development Kit.

Viso Settings

Choose File > Preferences > Viso Settings. Viso settings are needed if you want to import sessions created in the observation recording program Viso into The Observer XT.

Viso settings establish the connection between the computer running The Observer XT and the computer running Viso Services.

• Enter the IP address of the computer with Viso Services in the Services address field.
• Do not change the Services port value of 5672.
• Click the Test Connection button. If the two computers are connected properly, the status Connected appears.
