MotionLinx-Ai and MotionLinx-IO module status is indicated by several LED’s. All LED’s with the exception of the Ethernet Link and Activity LEDs are multi-colored and context sensitive. The following sections indicate the various meanings of all LED indicators.
Indicator States
| Indication | Rate | Visible Action |
|---|---|---|
| Slow Blink | 1 Hz | 500 msec. ON / 500 msec OFF |
| Fast Blink | 2.5 Hz | 200 msec. ON / 200 msec OFF |
| Slow Flash | 2 Hz | 250 msec. ON / 250 msec OFF |
| Fast Flash | 10 Hz | 50 msec. ON / 50 msec OFF |
| Single Flash | 200 msec. ON / 1000 msec OFF | |
| Double Flash | 200 msec. ON / 200 msec OFF/ 200 msec ON/ 1000 msec OFF |
