Status LEDs
Each eSynC has 2 primary Status LEDs. The mounting location varies. The eSynC products in a
casing always have the 2 primary Status LEDs mounted as shown in the following diagram.
Figure 1:
Typical eSynC Case
Units with Ethernet support also have two status LEDs mounted in the RJ45 receptacle, which
are described in the Ethernet RJ45 section. USB Hub units without Ethernet support have a
“USB connect” LED which indicates if a peripheral is connected to the adapter. The "Charge
Status" and "Device Link" LEDs are pulsed as a start-up test. The LEDs are pulsed once for an
Mk1 device, and 4 times for an Mk2 device.

Green
Rapid blink
See the Charge Status LED description for “rapid blink”.
1-second blink
See the Charge Status LED description for “1-second blink”.
On solid
A mobile device has been attached and detected.
OFF
No mobile device attached.

Rapid blink
The LAVA unit is in the bootloader. When the J15 jumper is installed,
the unit remains in the bootloader after power up. All “extended”
features are suspended while the bootloader is active.
1-second blink on both LEDs, and both
LEDs are synchronized
The LAVA product is waiting for a mobile device to be attached.
1-second blink on both LEDs, and
when one LED is on the other is off
The LAVA product has detected a mobile device and is waiting for
LTM to communicate. If the LTM application was not installed, this
LED state does not end and the “extended” features are not
functioning.
Flashing every 1.5 seconds.
Once LTM is running and communicating, the “Device Link” is on
solid and the “Charge Status” LED pulses every 1.5 seconds.
When the mobile device is being charged, the LED is mostly on.
When the mobile device is being discharged, the LED is mostly off.
This behavior is used to diagnose the battery modulation feature and
confirm that LTM is operational.
OFF
The LAVA product has no power.
Note: The 2-pin internal jumper is left open to permit the “extended” features of the eSynC to function. The LTM application must be installed
on the mobile device. This is the manufacturing default for all eSynC products.

Power has been applied to the LAVA product.
Off
The LAVA product has no power.
Note: The 2-pin internal jumper is shorted to disable the “extended” features of the eSynC to function. The LTM application is not required in
this state. If the LTM application was present on the mobile device, it will not run and does not harm remaining on the device. In this state, the
unit operates with only the “standard” features of the core nSynC products.
