Wired Network Operation
Many eSynC products provide a 10/100 Fast Ethernet wired interface. This feature relies on
standard support built into the tablet or mobile phone. A wired networking solution is more
reliable than Wi-Fi and has greater security.
Devices supporting Wired Ethernet operation provide options for dynamic address setup (DHCP)
and static address setup. The choice of address management is a Network system issue. The
Ethernet addressing configuration is performed within the device setup menu.
The device setup and status for the Ethernet port are located in the Connections > More networks
> Ethernet menu. The Ethernet menu can only be entered when a powered Ethernet adapter is
present. The standard device options permit the use of static address assignments or dynamic
address assignments via DHCP. The menu reports if the Ethernet adapter is active.
When using DHCP, the device attempts to fetch the network addressing information from a
DHCP server. If the addressing information is not located within the timeout period, the device
makes no 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 device in an enclosure or kiosk.
When the user disables the Ethernet adapter via the Connections > More networks > Ethernet
menu, the adapter remains disabled until enabled again by the user.
In some cases, an installation may choose to use Wi-Fi for network access rather than the wired
Ethernet support of the eSynC product. The eSynC product’s Ethernet interface can be disabled
when Wi-Fi is enabled using the configuration command “wifi-overrides-ethernet=1”.
The “permit-ethernet=0” command disables the Ethernet interface. Ethernet is permitted by
default.
