Hardware
Power supply
GW-ETH-01 is intended to be supplied by external stabilized 5 V DC connected to
clamp or to micro USB connector. If both are connected, the internal logic gives
priority to the supply from the clamp. Accumulator serves as a backup for external
power source and should be charged from it.
Standby mode
The GW is turned off by switching to the Standby mode – see Control pushbuttons below. All peripherals are disabled
and power consumption is minimized in this mode. Wake-up follows after reset or connecting of external power.
Powering from accumulator is controlled as follows:
•
if external voltage < 3.70 V then the Ethernet controller is disabled (reenabled after external power connecting)
•
if external voltage < 3.45 V then the GW is switched to Standby mode
