Active devices monitor the status of the loop constantly and can report the following loop issues which will be shown in the display of the decoder:

Loop Error

The loop is not connected anymore or has been cut. This error will be signaled by the RACE RESULT System with a long beep sound.

Loop Limit

The system cannot provide enough power for the selected loop power. Either the cable is too long or too thin. The Loop Power which has been set will still be delivered, however the user should expect a reduced read height.

High Noise

The average noise over the 2.4GHz channel is higher than a determined threshold, suggesting that you should select a different channel. It will not drastically affect the precision of transponders, as the 125kHz channel is used to time the transponder. Transponders will keep trying to send their packets for one second after the detection when the channel is noisy or busy. ActivePro and MotorKart transponders will store passings if it fails to send the passing.

If the warning continues to be shown, the user should change the channel ID of the device.

Overflow

Transponders are being detected faster than they can be sent to the decoder. The Active Extension has an internal buffer for 1000 detections. Should this buffer be full, detections will get lost and the decoder will show the Overflow error.
