Tablet PoE USB/Ethernet Hub

The STS-P2UE adapter provides wired Power over Ethernet connectivity and simultaneous charging (SimulCharge) capability for select Samsung tablets. This adapter includes two USB 2.0 (A-Type) ports for connecting two additional peripherals. LAVA’s SimulCharge technology allows the tablet to operate as a USB Host while continuously charging the battery.

Power over Ethernet (PoE) allows network data and electrical power to be carried over a Ethernet cable, eliminating the need for an electrician to install a dedicated power drop. PoE allows the Samsung tablet and STS-P2UE to be placed up to 328 feet (100 meters) from its power source.

The STS-P2UE provides superior tablet charging by converting the PoE signal to 5.2 volts for use by the tablet. This eliminates the issues associated with using the tablets original power charger.

Standard USB OTG Adapters do not allow the tablet to be charged while operating with USB accessories. This intelligent adapter is designed for robust operation allowing rapid switching between SimulCharge and Charge-Only mode.

The LAVA product can be switched into Charge-Only mode to rapidly replenish the battery in the same manner as USB Charger with a Direct Charge Port (DCP) as defined by the USB Battery Charging specification v1.2.

The STS-P2UE can be used on its own, or as part of a third-party enclosure solution, supporting a variety of kiosk-type applications.


Samsung Galaxy Tab (see compatibility list of supported devices)

Power is provided over the RJ45 LAN connector from a PoE enabled Network Switch. The PoE interface provides up to 10.4 watts of power for the STS-P2UE and tablet charging.

The Aux. 5V Input can optionally be used to power the STS-P2UE when no PoE is applied over the RJ45 LAN Connector. This power option is present for initial testing prior to enabling PoE. A standard USB Charger/Power Supply is used, such as that provided with the tablet. The power supply must not exceed 5.25 volts.
