USB 2.0 Ports for User Accessories
The LAVA products include an internal USB 2.0 Hub, which is used to connect integrated and
user-supplied USB accessories. Up to five user-accessible USB 2.0 ports are available depending
on which LAVA product is selected.
User accessories are attached to USB 2.0 ports with a standard A-type receptacle. Each
receptacle provides power to each USB Accessory up to a maximum of 500 mA, as per the USB
specification. The power supply used must have sufficient capacity for the mobile device, LAVA
hardware, and USB accessories.
A LAVA product must be powered for a USB-A receptacle to function. The LAVA products
have a dedicated power input and are not intended to draw power from the tablet or mobile
phone.
A power budget must be developed for a system to handle additional USB accessories and the
related cables. Power loss in each cable results in lower voltages at each device. Using self-
powered USB Hubs may be required in some systems, to offload the power supply responsible
for the tablet or mobile phone.
LAVA Tablet Manager (LTM) Application
The LAVA Tablet Manager application must be installed on the mobile device to manage each
LAVA product. The LTM application runs in the background on the mobile device. LTM works
with Android v5.1.1 and newer.
LTM is available through the Google Play Store (LTM v5.**) and is also distributed as part of a
LAVA Software Release Package (LTM v4.**), which includes a copy of the eSTS Installation
Manual. LTM must be used with a LAVA product that is matched to the mobile device being
used. Please contact LAVA sales or technical support for further details at
www.lavasimulcharge.com.
Once LTM is installed, the Product Family, Protection Type, and Ethernet usage are configured
through the built-in setup manager. All other configuration parameters are optional. These steps
are described in detail in the installation manual. No other license or special activation is
required.
During normal operation, the application launches automatically when it detects the LAVA
hardware and is intended to run quietly in the background. If the application is accidentally shut
down, it is woken up within 7 minutes by the recovery timeouts that are built into the LAVA
hardware.
LTM typically operates in a "Background Mode" to ensure that only the customer applications
are seen by the device user. Clicking on the application icon four times within a few seconds
forces the application into the “Configuration Console”, which allows the configuration to be
reviewed or modified. The "Force to Background" option in the overflow menu places LTM
back into its preferred state.
