8.4 Sleep mode
The SCS1000 and SCS3000 have a so-called sleep mode. This is a low-power consumption state that allows a vehicle to be
switched on and off without draining the battery.
Several options are available to configure the behaviour of this sleep function.
8.4.1 Power Config
When a module is to go into sleep mode or wake up again is defined in the power configuration.
The configurable sleep options include:
• Dedicated wake pin
• High potential on one of four selectable inputs (for SCS3000)
• Wake-up on general CAN activity
• Wake-up on defined specific CAN activity with defined data content.
This option results in increased quiescent current input in sleep mode.
To access the Power Config and make settings for sleep mode, select »Device«, »Power Config«. A live connection with a module,
for example in »Monitor« mode, is not possible during this time.
The Power Config is saved as a text file that can be saved on the PC and loaded into devices.
The »Save« and »Load« buttons in the lower part of the window are used to open and save offline configurations that are saved on
the PC. The »Get« and »Set« buttons are used to upload a configuration from a connected device and to save the Power Config
on a connected device, respectively.
To edit the sleep configuration, make sure that »read only« is unchecked and enter text in the text area. To set, change only the
numbers behind the square brackets [ ]. The required format is described in the configuration itself.
A comment can be added preceded by »//«. However, comments are only saved offline and are not retained in the device. The
Power Config file can also be edited with any text editor, e. g. Notepad.
