What's New in DanioVision

DanioVision Observation Chamber

The interface of DanioVision DVOC-0050 has been completely redesigned.

Communication with the EthoVision XT computer goes through Ethernet.

There are pre-defined communication lines for the White Bottom Light, the TopLight Unit, the Tapping Stimulus, the DanioVision Temperature Control Unit DVOC-TCU and the Optogenetics setup.

• Two BNC connectors are reserved for the Optogenetics setup.
• Two TTL ports are available for additional hardware control. Each port includes two input lines and two output lines.
• There is a new physical connection for communication with the temperature sensor in the Temperature Control Unit.
• You can switch on the White Bottom Light manually. To do so, operate the button at the right side of the camera.

EthoVision XT

Because the hardware components have changed, the software interface for controlling DanioVision has changed. You can find it in the EthoVision XT Experiment Settings. Choose Setup > Experiment Settings, select Use of Trial Control Hardware. Click Settings and choose DanioVision DVOC-0050/TCP.

• The White Light Stimulus is now called White Bottom Light.
• The Tapping Stimulus stays as is.
• The TopLight Unit has now specific names: White Top Light and RGB Top Light, for white and multi-color LED arrays, respectively.
• When programming the White Bottom Light on/off actions, you can set the fade duration in milliseconds, seconds, minutes, and hours (maximum 24 hours).
