MyNoldus Knowledge Base Related to EthoVision XT EthoVision XT is unable to detect the Noldus I/O Box

EthoVision will report that the USB I/O Box is not connected if the connection is lost or if it is not present when you attempt to start the experiment or test connections. Use the guidance below to troubleshoot this situation.

Connect the I/O Box before starting EthoVision

EthoVision will only detect the box if it is connected when EthoVision starts. If you plug in the I/O Box after starting EthoVision, close EthoVision and reopen it.

Check connections and power supply

Besides the connected Noldus or third-party hardware (via TTL or SDI ports), there are two main cables required. These connections apply to both the USB I/O Box and the Mini USB I/O Box:

  • The USB cable connects the I/O box to the computer. If connected properly, the USB light on the I/O box should be lit.
  • A power cable must also be connected. The power LED light should be on. Without proper power, the box might communicate via USB but will not have enough power to control external devices.

USB IO Box Connection

Is the I/O Box detected by the computer?

If both cables are connected and the box is still not detected by EthoVision, verify that the computer recognizes the device:

  • Open the Start menu and click the Settings (gear) icon.
  • Go to Devices.
  • Under the Bluetooth & other devices section, look for a device named I/OWarrior56 listed under Other Devices.

If you do not see this device, the driver may be missing, or the I/O box may be malfunctioning.

Is the correct I/O Box selected in your Experiment Settings?

You might receive a connection error if the incorrect interface was selected when creating your experiment—for example, selecting the Mini USB I/O Box instead of the standard USB I/O Box. EthoVision will search for the wrong hardware and fail to detect it.

I/O Box Interface Selection

The USB I/O Box is labeled "USB-IO Box" and features 13 RJ45 ports labeled SDI Control and 12 RJ45 ports labeled TTL Control.

The Mini USB I/O Box is labeled "mini USB-IO box" and includes 4 RJ45 ports labeled TTL Control and 1 RJ45 port labeled SDI Control.

If you have assigned devices to the wrong interface, go back to that interface, remove the incorrect device assignments, and then add them under the correct interface. Alternatively, you can create a new experiment with the correct settings.
