ETAS ES800 System | User Guide
The Embedded PC of the ES820.1 module is started. The ES820.1 can be accessed
with the "Drive Recorder Configurator" configuration program. The Drive Recorder
function of the module is available.
11.3 "Wake-Up" Function
11.3.1 "Wake-Up" Function within the ES800 System
If the ES800 system is used in a vehicle, the energy consumption must be as low as
possible since the measuring setup is supplied by a battery. The system therefore
offers various options for switching the modules in the stack to the "On" operating
state only when necessary.
The modules of the system can automatically switch between the operating
states "Standby" and "On" with the "Wake-Up" function and automatically start
the measurement after switch-on.
The ES800 system and ETAS modules connected to it automatically switch to the
"Standby" operating state if certain interfaces no longer receive link signals for
some period of time or the host computer is being switched off or disconnected.
As soon as at least one of these interfaces receives link signals or the host com-
puter is activated again, the system automatically changes to the "On" operating
state ("Wake-Up" function) and automatically switches on all ETAS modules con-
nected in the measuring system.
11.3.2 "Wake-Up" and "Sleep" Function with ETAS Modules from Other
Series
The "Wake-Up" and "Sleep" functions of the ES800 modules that are performed
using ETAS modules from other series, which are connected to the "FE" interface
or via the "GE-HOST" Gigabit HOST interface of an ES600.2 module to the "GE"
interface of an ES800 module, are supported.
NOTE
The events that activate and deactivate the system can be flexibly configured
(e.g., via the web interface, see chapter 11.6 on page 83).
