Battery Modulation for Samsung Tablets
DHCP Recovery
Ethernet Adpter for Samsung Tablets
Screen Brightness Menagement for Samsung Tablets


The eSTS-P2UE operates a tablet in SimulCharge mode. This technology allows the charging of the selected Samsung tablets while interacting with USB accessories. Standard USB OTG Adapters do not allow the tablet to be charged while operating with USB peripherals.


The battery modulation allows the tablet to be repetitively charged up to an upper set point battery level and then allowed to discharge to a lower set point battery level. This mimics the standard charge cycles of charging a tablet and then disconnecting the charger before it will start a trickle charging (overcharging).

The Network Recovery Operation enables tablet recovery from the failure attempts to connect to the network. It eliminates the issues with establishing a network address (TCP/IP address) for the tablet from a DHCP server.

The RBM technology improves battery tablet longevity, and enhances a DHCP network operations.


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

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


The eSTS-P2UE features a 10/100 Fast Ethernet interface that enhances the reliability and security of an internet connection. The Samsung tablet can use the dynamic address (DHCP) or static address for the network communication.


The LAVA Tablet Manager lets you control the brightness of the tablet based on a time of the day. This reduces the tablet heat generation, power consumption, and optimizes the brightness for the commercial use.

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.

Bloated Samsung Tablets

eST-SimulCharge™ P 2UE

Tablet: See list of Tested Tablets
Power Supply: Power is provided over the RJ45 LAN connector from a PoE enabled Network Switch on PoE Injection. The PoE interface provides up to 10.4 watts of power for the eSTS-P2UE and tablet charging.

The Aux. 5V Input can optionally be used to power the eSTS-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.
