GW-ETH-02A
Appendix 1 – LED indication
Run operation
•
When the gateway is started-up all LEDs are on for 1 s.
If the GW is switchwed on by connecting the USB cable to PC with IQRF IDE running, the GW detection by IDE
takes about 5 s.
•
After the start up the gateway performs a check of its hardware. If there is no problem in HW, the green LED is on
for 2 s.
•
After HW check, the gateway is connecting to Ethernet/LAN (and to Cloud server, if enabled). This is indicated by
short flashing of green LED, 100 ms on / 1 s off.
•
When the GW is successfully connected the green LED flashes 500 ms on / 500ms off. The GW works in normal
mode.
•
When the gateway is connected to IQRF IDE Terminal, the communication over Ethernet is disabled (SPI
communication is forwarded to the Terminal but not to the Cloud). This mode is indicated by short flashes of green
LED, 100 ms on / 100 ms off.
•
When the GW is connected to IQRF IDE GW Tool, the communication via Ethernet is not limited. The GW works in
normal mode.
•
When the GW communicates with TR module, orange LED flashes for 10 ms.
Start-up errors
After the start-up the GW performs hardware check. If there is a critical error prohibiting basic functionality, the GW
goes to error state, see below. This is indicated by red LED permanently on.
