LED Indications

This section summarizes the LED indication rules for CAN products, helping users quickly identify device status during installation, connection, debugging, and troubleshooting.

Generations

• 1st Generation: Dual-LED design with red/blue alternating blink, red steady on, blue steady on, and TX/RX quick blink behaviors.
• 2nd Generation: Full user-manual style guide with visual status cards, timing diagrams, and troubleshooting tips.

Recommended Reading

• For first use, start with the status quick reference in the 2nd generation guide.
• If the device is connected but communication is abnormal, check the abnormal indications and actions section first.
• If your product belongs to the 1st generation family, read the idle-state quick reference first, then use the red/blue quick blink patterns to judge bus activity.
