LAVA eSynC USB C Ethernet Adapter with Voltage Converter User Guide
Getting Started
Congratulations on the purchase of an eSynC product! The eSynC product family (formerly known as LAVASynC+) makes it possible to simultaneously charge select USB-C mobile devices while working with various USB peripherals such as printers, mice, keyboards, and even external hard drives. This mode of operation is called SimulCharge.
In addition to simultaneous charging, all eSynC products support LAVA’s Recovery & Battery Modulation (i.e. RBM) technology when coupled with the LAVA Tablet Manager Application (LTM).
The eSynC extended features rely on the LAVA product working in unison with the LTM application, therefore the installation of LTM is mandatory prior to wing an eSynC product. LTM can be downloaded from the Google Play Store and is also available as part of a Software Release Package which contains the LTM.apk file and extra utilities that may be useful. The package may be downloaded in the form of a zip file from a web link that is provided by LAVA Sales/Support. You may contact LAVA by phone: +1-800-241-LAVA (5282), or email: sales@lavalink.com.
The eSynC product line provides the following features:
- Access USB peripherals while simultaneously charging a mobile device
- Keep a mobile device connected to power 24/7
- Maintain battery health
- Modulate charging based on actual battery charge levels
- Manage Screen Brightness based on time of day
- Attach multiple USB peripherals at any time
- Connect and access multiple USB peripherals (product specific)
- Provide a wired Ethernet connection to a mobile device (product specific)
- Power mobile device via PoE (product specific)
- Power via an unregulated DC power supply (product specific)
Your hardware purchase will include:

OR -
b. Download LAVA Software Release Package
Alternatively, the LAVA Software Release Package may be downloaded from a web link in the form of a zip file, and therefore needs to be extracted/unzipped. The zip file can be extracted from a web browser on the mobile device or a PC, using one of many online extraction tools that are freely available. If the zip file is extracted on a PC, it will need to be transferred onto the mobile device using a memory stick and an OTG adapter such as the LAVA Charge Plus USB-C for USB-C receptacles. The advantage of this method is the software can be installed on a mobile device even when it is not connected to the internet.
Allow mobile device to install apps from unknown sources
Since the Software Release Package is not downloaded from the Google Play Store, the mobile device will need permission to install apps from unknown sources.

Setup Procedure:
-
Plug the USB Charger into an AC power source and connect the USB-C connector into the eSynC port marked “USB-C Power Adapter”.
- For PoE units: Select eSynC devices can be powered using a PoE Switch/Injector connected to the Ethernet Port.
- For VC units: Select eSynC devices can be powered using a 9-36V (12W or better) power supply, with a 2 mm center positive barrel jack connector, connected to the port marked “9-36 VDC In”. The attached power supply and wiring are responsible for providing short circuit protection.
Note: If using either PoE, or the VC power input, do not plug a power supply into the port marked “Aux 5V Input”.
Note: For VC units, when connecting the LAVA product to the supply, ensure the wiring is such that the center pin is positive. lithe polarity is reversed the damage to the LAVA product is immediate. Application of the wrong input voltage violates LAVA’s Manufacturer Warranty.
-
Once the product is powered, the Yellow eSynC status LED light will start blinking, indicating that the unit is receiving power.
-
Plug one end of the USB-C to USB-C cable into the mobile device. Plug the other end into the eSynC port marked “Mobile Device”.
-
Once the LAVA product is powered and connected to your mobile device, you will receive a pop-up message regarding opening LTM when a USB is connected. You will receive this pop-up every time you connect your mobile device to a eSynC product, unless you click “Always open LTM…”. Click “OK” ( Figure ii).
Figure 11: Pop-up message received upon connecting LAVA product to mobile device -
Once the USB-C cable is attached, the Green eSynC status LED light will be illuminated, indicating that a connection has been established with the mobile device.
-
To verify that LTM has detected the hardware connection, consult the “STATUS” window on the LTM homepage on your mobile device. Prior to connecting your LAVA product, the “STATUS” window will say “CONTROLLER NOT DETECTED” (Figure 12).
Figure 12: STATUS window prior to connection of the LAVA product
Once you see “Controller detected” in the STATUS window (Figure 13), the LTM application has successfully detected the LAVA hardware.
_
Figure 13: STATUS window upon detecting a connection to the LAVA product_
If your product is functioning properly, “Controller detected” will be replaced by a “Controller ran @hh:mm:ss” (hour:minute:second) time which will update approximately every 30 seconds (Figure 14).
Figure 14: STATUS window once the product is functioning properly with LTM -
After establishing a connection with the mobile device, the Yellow eSynC status LED light will begin blinking on and off to indicate whether the eSynC product is in a charge cycle (eg. Yellow LED is mostly on and briefly off) or discharge cycle (eg. Yellow LED is briefly on and mostly off). The STATUS window on the LTM home screen will also indicate if it is charging or discharging, with a message that says “charging phase” or “discharging phase” (Figure 14).
-
Plug your peripherals and/or Ethernet cable into the eSynC product (if applicable).
Concluding Steps
-
Step 1. Enable Screen Brightness Management (optional)
If you would like to install or learn more about the Screen Brightness Management feature, refer to the “Advanced LTM Settings” document. This step is strongly recommended, but optional. -
Step 2. Set LTM to Background Mode once ready for deployment
-
a) The LTM and hardware setup process is now complete. Once you have verified your setup and you are satisfied with your configuration, you may set the LTM application to Background Mode.
-
b) On the LTM homepage, press the Overflow menu (3 vertical dots) in the top right corner.
-
c) Select “Background Mode”.
-
d) If the application disappears from view, it has been set to Background Mode successfully.
Revert LTM to Configuration Console
When LTM is in Background Mode, it cannot be opened by simply clicking the application logo on the mobile device home screen. There are two ways to revert the application into Configuration Console:
- Close all active applications on the mobile device. Once they have been cleared, clicking the LTM app once will launch it in a visible state.
- Click the LTM logo several times within a few seconds.
Wired Ethernet Configuration (for Ethernet-capable products)
Depending on your mobile device and network configuration, you may need to enable or reconfigure the wired connection settings on your device.
After establishing a connection with the eSynC product, the Ethernet
configuration option should be available on the Settings Menu of your mobile
device (i.e. Settings > Connections > More connection settings > Ethernet).
Figure 15: More connection settings on mobile device
After establishing a connection with the eSynC adapter, if the Ethernet option is greyed out or unavailable, the mobile device likely does not support a wired connection. If this is the case, there is likely nothing that can be done to enable this feature on your mobile device.
Assuming that the Ethernet option is available, it may be necessary to enable
or disable the wired connection on your mobile device. This can be done by
ensuring the Ethernet option is enabled or disabled on the Ethernet page.

Most mobile devices will have DHCP enabled by default. If your network does not have a valid DHCP server, you will need to manually configure an IP Address for the mobile device. Check with your network administrator before using static IP settings.
To manually configure an IP Address, you will need to disable the Ethernet
connection on the Ethernet page before selecting “Configure Ethernet Device”.
From here, you can select “Static IP” and specify the IP Address settings to
be used by the mobile device.
Figure 18: Example of Static IP configuration on mobile device
Once the IP Address has been configured, you will need to re-enable the Ethernet connection in order to use the wired connection.
