Usage manual for Barkr TIMR Standard

The package contains:

  • One display
  • 2 emitter sensors (single pod)
Agility Timer emitter pod
  • 2 receiver sensors (double pods)
  • 2 sensor cables (20 meters)
  • 1 extension cable (20 meters)
  • 1 remote control (start / stop)
  • 1 replacement fob (for when the start and stop jumps are the same)
  • 1 emergency battery powered emitter (battery not included)
  • 1 USB cable (1.5m) that plugs into your computer
  • 1 USB extension cable (1.5m)
  • 4 metal legs for the sensors


  • Mount the display in the desired place, protect from rain, if announced, the sensors are waterproof but the main display is only splashproof.
  • Arrange the sensors legs near the first and last jumps.
  • The emitter sensors (single pods) go on the legs with thin lines. 
  • The receiver sensors (double pods) go on the legs with thick lines.
  • The plastic sensors go on top of the lines. The markings are informational, you should set the emitter pod to middle point between the receiver pods. This ensures that dogs jumping too high or too low trigger. 
  • Arrange the cables, use the extension cable where needed.  The plug on the right (as you look at the screen) is for the Start and the other one is for Stop.
  • You should see the LED on the back of the emitter pod light up to know that it is powered.
  • If a dog does not trigger the Stop sensor you can close it with your remote control.
  • Plug the USB in the computer and the bottom of the screen if you want the times entered automatically. 
  • If the same jump is the start and the stop use the provided dongle to simulate a Stop sensor and the start sensor will become stop after 5 seconds.


ERR: Stop  or ERR: Start scrolls on the screen:

This means that the connection is broken either on the start or stop circuit for more than 5 seconds. To fix this start checking connections on that circuit.

  • If the Receiver pod LED is on but the Emitter LED is off and the connections are ok you can use the emergency emitter powered by a 9v battery.
  • Check that the pods are aligned. 
  • There is an audible clicky sound when the Receiver sensor is triggered. Check that you hear that.
  • Contact me.

Sensor  is not being triggered by the dog jumping

If the sensors work when tried with a hand or person but not by a dog this might mean that:

  • The pods are not aligned properly. This is more likely to happen for very small dogs. In this case try to align the emitter pod with only one receiver pod.
  • The dog jumps over the ray. The infrared light forms a triangle to the receivers. If the first or last jump makes the dog jump very near the wing make sure that on that wing you place the receiver pods.
  • The emitter pod from the other sensor triggers the receivers from the problem sensor. 

Screen freezes.

If you use a laptop on battery power please don’t let it turn off / hybernate / stand by because it sends a shut down message that shuts down the computer inside the display. If this happens you need to both unplug it from the 220v power and the USB power to reset it. Just unplugging it from the power does not work as the USB has enough power to power the computer but not the display or sensors.

Also, sometimes, abruptly unplugging the USB cable will freeze the timer. 

If you need to reset for any other reasons, unplug it from both power sources.

Lost 220v power

If you lose 220 power the screen still lights up, but there isn’t enough power for the sensors. You cannot use it like this.

I can’t photographs or film the timer.

The screen uses a system that displays only a quarter of the LEDs at the same time, and cycles them very quickly. If you photograph in daylight new cameras are very fast and will only show a quarter of the LEDs. You need a professional camera with a manual  longer exposure time.

The remote only works from close

Then you need to replace the battery. People often play with the remote to start / stop the timer and the battery empties much faster.

The screen flickers

Some of the screens start flickering when left in the sun for a few hours. We have no way to test this before purchasing the screens and since we strive for a low price point, it sometimes happens. It should be ok if the timer is in the shade or ventilated, you could also let it cool down. Please contact us so we have a better idea when / why this happens.
