Description
Barrel Connector
Center contact fork type for better grip
9-30 VDC Input with center = (+)
Reverse polarity protection up to 30 VDC
USB Type C
Connector
USB VBUS 5V powering (default setting)
SGX can provide VBUS 5V 0.5A out if configured as USB host, and powered by
Lantronix provided wall adaptor, or PoE power source class 2 (hardware optional)
Ethernet PoE
RJ45 Connector
PoE power module is optional
Must provide class 2 PoE power source
Supports power inputs at both spare pins or Ethernet center taps with full bridge
diodes for polarity in-discrimination.
Power
Consumptions
1.9 W typical if configured as USB Device, or USB Host - but not providing VBUS 5V
power
5.5 W maximum if configured as USB Host and providing out VBUS 5V power
The internal hardware configuration allows more than one or all power sources
applied at the same time for power back up if one of them happens to fail (
caution:
may not be error-free
). Not designed for one power source to take precedence over
the other.
