# Use a remote control to start and stop acquisition

Aim

To start and stop data acquisition when standing far from the EthoVision XT computer.

Prerequisites

▪You need a remote control with Page-up (<) and Page-down (>) buttons, such as those typically used for PowerPoint presentations.

Procedure

1.Close EthoVision XT.

2.Browse to my.noldus.com, log in or register. Click Downloads, then EthoVision XT, then Drivers and Tools, and download the file for remote control. Save remote_control.zip somewhere to your EthoVision XT computer.

3.Extract and double-click remote_control.reg file and when a message appears click Yes. You can now use the remote control.

4.Switch on and connect the remote control. This is usually done by plugging a USB receiver into the EthoVision XT computer.

5.Start EthoVision XT and choose Acquisition > Open Acquisition.

6.To start a trial, press Page-up (<) on the remote control.

7. To stop a trail, press Page-down (>) on the remote control.

Notes

▪Signals from the remote control will only be recognized:

▪While acquiring data, and if the trial is not finished yet.

▪When you are not entering independent values.

▪When you are not browsing through the video.

▪For earlier versions, download the full installation package and look for the Remote Control folder under Utilities.

▪If your PC is connected to a network through Wi-Fi, you could control EthoVision XT from a smartphone using one of the apps available, provided that the network’s security settings allow communication.

▪If you have the USB-IO box and the TTL Port Tester PTTB-001x, you could have EthoVision XT start tracking when you press the button on the TTL Port Tester. To do so, connect the TTL Port Tester to a TTL port of the USB-IO box. In the Trial Control Settings, create a condition based on the TTL Port Tester that becomes true when the button 1 is pressed. Place the condition box between the Start Trial box and the Start track box. You use the TTL port tester as a remote control. Note that with this solution you must click the Start trial button in EthoVision XT, which then waits for the button press.
