How to interpret the heartbeat LED status of the B308 octo-relay module.

[#1]

Flash Pattern

• Flashes at 1/sec rate:
  • Normal State: Indicates normal operation state.
• Flash at 3x/sec rate.
  • Communication Error State: Indicates an SDI2 communication error, or the device has nothing programmed to it.
• ON Steady.
  • Trouble State: Indicates a trouble condition exists.
• OFF Steady.
  • Trouble State: Module is not powered, or some other trouble condition prohibits the module from controlling the heartbeat LED.
• OFF for 3 sec, then flash.
  • Firmware version* Firmware Version: For example, if the version is 3.2.1, the LED pulses 3 times and pauses for 1 sec, pulses 2 times and pauses for 1 sec, and then pulses 1 time. After flashing the Firmware version, the heartbeat LED stays OFF for 3 sec before indicating the module state.
