Remote Audio Device LEDs

Provides status information about the health of the shielded CAT 5e connection between each RAD and HAL. The numbers correspond to the RAD ports in the lower right corner of the rear panel. For example, the LEDs for number 1 provide information about the RAD connected on port 1. Each LED corresponds with one twisted pair within the shielded CAT 5e cable. If the twisted pair is functioning properly, the LED displays a solid green light when the HAL is programmed to expect the RAD model that is physically plugged in. When all cable pairs are working properly, but HAL is not yet programmed for the connected RAD model, all four LEDs flash red. Note that flashing red is a good thing: the cable’s good – just program HAL and you’re done.

note: The Remote Audio Device LEDs on the front panel differ from those on the rear panel. The front panel LEDs provide information about signal activity on each audio channel. See Overview of HAL Devices for more details.

tip: You can use the Remote Audio Device LEDs on the rear panel and on the RAD to troubleshoot connection problems. See Troubleshooting HAL Hardware and Troubleshooting RAD Devices for details.
