Status Leds
twidunode2 is provided by 4 operating leds useful for operating state identification. Their status assume different meanings depending on operating way:
- Upgrade firmware: without external voltage source
- Funzionamento PoE: with any external voltage source
| colour led | function | action | update | PoE function |
|---|---|---|---|---|
| green | PoE load | off | - | twidunode2 off or in firmware update with blinking orange, firmware update error, update again |
| green | PoE load | fixed | - | twidunode2 on, PoE load connected and on (current absorption >50mA) |
| green | PoE load | blinking | - | twidunode2 on, carico PoE load not connected or off (current absorption <50mA) |
| red | battery | off | - | no battery connected |
| rosso | battery | fixed | firmware update error | battery is connected and in supplying phase |
| red | battery | blinking | - | battery is connected and in charging phase |
| orange | usb | off | twidunode2 not connected | USB not connected |
| orange | usb | fixed | twidunode2 connected as per Mass Storage Device | USB connected as per virtual COM to host |
| oranage | usb | blinking | - | USB connected as per virtual COM to host and updating/passing data with green off, firmware update error, update again |
| yellow | canbus | off | firmware to be load | CANBUS not connected, no data exchange |
| yellow | canbus | fixed | new firmware to be load/loaded | - |
| yellow | canbus | blinking | - | CANBUS connected, data exchange canBUS/USB |
| all | alarm | fixed | - | POE_VIN_OVER_VOUT Overvoltage, when the difference between Output voltage and setted Voltage exceed 1V (Vout-Vset>1V). For istance when it is applied a DC-IN voltage that exceeds 24V. |
| all | alarm | fixed | - | POE_OUT_OVERLOAD Overload, Load Current absoprtion exceeds maximum current limit equal to 3A. Please wait for few seconds in oder to allow twidunode2 to perform more attempts. |
Note: POE_OUT_OVERLOAD status is managed by twidunode2, It means that the load current absorption exceeds the current limit.This scenario depends on several factors as per equipments characteristic to be supplied. In order to aoid this situation, twidunode2 try many times power-on, generally after 1-2 second, the device switch on.
