INSTALLATION
The LED in the top-left corner of the connector turns on when an Ethernet cable
is plugged in and a valid Ethernet carrier signal has been detected. The LED goes
dark briefly whenever data is being exchanged over the cable. The LED in the
top-right corner of the connectors is a speed indicator. It turns on when operating
at 100Mbps and is off (dark) when operating at 10Mbps.
The USB ports are USB2.0 compatible and can supply up to 1A at 5V. They may
be used with various supported IT devices such as RS485-to-USB converters or
WiFi adapters.

The multi-switch can be used to navigate the LCD menu system. By default, any
action seen from the multi-switch will wake the backlight to ensure a viewable
interface.

Time Reference
During normal operation, the eGauge maintains accurate time by synchronizing
with an NTP server, such as one of the public servers available at
ntp.org
. Since
NTP provides atomic-clock accuracy, there is usually no need to set the time man-
ually.
When the NTP server is not accessible, either temporarily (e.g., after a power fail-
ure) or permanently (e.g., at a remote site), the eGauge relies on a Super Capacitor
backed real-time clock to maintain proper time.
