System Checks for Connected Devices

Modified on Fri, 04 Nov 2022 at 10:19 AM

Before timing can commence, you need to check that the decoders are connected and working correctly, plus any other devices you need for your event.


The status of any decoder(s) can be seen in the bottom left corner of the screen:

The decoder is connected and running with the number designating the loop signal noise.

The decoder is connected and running, but has high loop noise. This means that weaker transponders may not be picked up.

The timing cannot connect to the decoder.

The decoder is connected, but is stopped, i.e. will not record any laps (Tag Heuer / Chronelec decoders only). The decoder will be started when the first session is loaded or can be manually started by right clicking the decoder button and selecting start decoder.

Note: It is not possible to get connection / noise information for Tag Heuer sector decoders – the status shown is just an indication that they have been configured.

The status of the start/finish LED display (if configured) is shown above the sectors.

Unable to connect to the display – hover over to view more information

Connection is working

Note: Most displays do not confirm messages, so OK may just mean that the timing is able to communicate with the COM port, but does not guarantee that the message has reached the display (e.g. the cable may not be connected or there is no power to the display)


If an e-flag (or other compatible LED display) is installed, the status will be shown, as follows: 

Unable to connect to the Alpha E-flag controller . Hover over for more details

Connection is working

For the live timing to work, there needs to an internet connection. If connected successfully the following icon will be green:

Green means it has connected to live.alphatiming.co.uk. If it changes to orange it means the connections is slow.

Red means it is not connected. This could mean an absence of an internet connection or the results URL in the promoter settings is wrong.

Please check all your network and/or power connections and test your internet connection before calling Support.
