*Note Antenna Position*
Antenna:
The pX2 OEM module uses a UFL connector, Ensure proper orientation as seen above to prevent damage
to the pX2 module and to the development board.
Ethernet LAN:
The Ethernet LAN port is a standard RJ45 port to connect local network devices. The default IP address for
this port is 192.168.168.1.
Ethernet WAN:
The Ethernet WAN port is a standard RJ45 Port that can be used as a separate WAN port for Router
functions, or can be bridged (via software) to the LAN as a additional switch port for local devices.
The pX2 development board can be powered using Passive PoE on the WAN port using a PoE injector
that meets the following requirements:
Power:
The pX2 development board can powered using an input voltage in the 9-30 VDC range.
