further attempts. The user must manually retrigger the Ethernet interface to start the DHCP
process. The retrigger is a simple matter of pressing the Ethernet "box" again in the "More
networks > Ethernet" menu. The eSynC Network Recovery automates the network restart, which
is critical for embedding a tablet or mobile phone in an enclosure
When the user disables the Ethernet adapter via the Connections > More networks > Ethernet
menu, the adapter remains disabled until enabled again by the user.
“PoE-Ethernet” RJ45 Port and Indicators
The PoE Ethernet port has all the features of the Ethernet port described in the previous section,
as well as the ability to receive power from the network cable. All power for the eSynC product,
device charging, and attached USB accessories are provided by the PoE-Ethernet port.
A “PoE-Ethernet” port is present on the eSynC-PE and eSynC-P2UE products.
This port is attached to a Network Switch, which has been configured for PoE operation. Use of
a PoE Injector allows a non-PoE switch to be used with the eSynC-PE and eSynC-P2UE.
Warning:
When supplying power using the “Aux. 5 Volt” input, you must
not use PoE-supplied power.
Internal Jumpers
Each eSynC product has a pair of internal 2-pin jumpers. The jumpers are not installed as a
manufacturing default. These jumpers handle special conditions. In practice, most users will
never use these jumpers.
Internal Jumpers
Label
Description
MODE
This 2-pin jumper is used to disable all the extended features of the eSynC, including Battery
Modulation. With the jumper installed there is no need to install the LTM application. If the
LTM application is present, it does not run.
No jumper permits all extended features to function, and the LTM application must be
installed on the tablet or mobile phone. This is the manufacturing default.
J15
The 2-pin J15 jumper forces the Bootloader to be run on power up and remain active. The
installed application is not affected. This jumper is used to recover from an upgrade
application image which is not behaving correctly.
Do not
install a jumper on J15.
