If a RAD is functioning properly and communicating with the HAL, all four of its LED status indicators (Power, Comm, Audio Rx, and Audio Tx) will be green. The following table details possible causes and solutions if one or more of these indicators are off or red. If you detect a problem with a RAD, we recommend first checking the HAL to determine if the problem is originating there.
note: It is best to check these indicators in the following order: Power, Comm, Audio Rx, and Audio Tx. If the power isn’t working, nothing else will work. If the data communications (Comm) isn’t working, Audio Tx will not work. If Audio Tx isn’t working, Audio Rx will not work.
| RAD LED Indicators | Possible Causes | Suggested Action | |||
|---|---|---|---|---|---|
| Power | Comm | Audio Tx | Audio Rx | ||
| OFF | OFF | OFF | OFF | Room is dark and LEDs are off. | Shine a light on the RAD front panel. |
| The HAL is not powered. | Power on the HAL. | ||||
| A mis-wired or broken cable is disrupting power to the RAD. | Use a cable tester to verify shielded CAT 5e termination. | ||||
| If using a punch block, verify that the brown pair is properly punched. (Assuming T568B termination). | |||||
| The cable is not plugged into a HAL. | Plugging the RAD cable into some other device (like an Ethernet switch) will not supply power to the RAD. | ||||
| RED | GREEN or RED |
GREEN or RED |
GREEN or RED |
There is excessive voltage drop between the HAL and RAD. | Verify it is 24 AWG (or heavier) cable. |
| Verify the cable length from HAL to RAD has not exceeded 150 meters. | |||||
| GREEN | RED | RED | GREEN or RED | The twisted pair in the shielded CAT 5e cable that carries communications data is mis-wired or broken. | Use a cable tester to verify the wiring of the shielded CAT 5e cable. |
| If using a punch block, verify that the orange pair is properly punched (assuming T568B termination). | |||||
| GREEN | GREEN | RED | RED | The RAD is not receiving an audio stream from the HAL. | Use a cable tester to verify shielded CAT 5e termination. |
| If using a punch block, verify that the green pair is properly punched (assuming T568B termination). | |||||
| GREEN | GREEN | RED | GREEN | The HAL is not receiving an audio stream from the RAD. | Use a cable tester to verify shielded CAT 5e termination. |
| If using a punch block, verify that the blue pair is properly punched (assuming T568B termination). | |||||
| flashingGREEN | flashingGREEN | flashingGREEN | flashingGREEN | The RAD is in Locate mode. | End Locate mode for that RAD from within Halogen. |
| flashing RED | flashing RED | flashing RED | flashing RED | The connected RAD does not match the configured RAD model. | Adjust the configuration or connect the correct RAD model to the port. The simplest solution is often to swap RADs in the Halogen software. |
