2.3.4.1.2
Reset, Pending Deactivation
State after reset or deactivation from the line interface by info 0. Note that no activation
from the terminal side is possible starting from this state. A ‘DI’-command has to be
issued to enter the state ’Deactivated’.
Deactivated
The line interface is deactivated and the IOM-2 interface is or will be deactivated.
Activation is possible from the line interface and from the IOM-2 interface.
Power-Up
The line interface is deactivated and the IOM-2 interface is activated, i.e. the clocks are
running.
Pending Activation
Upon the command Activation Request (AR) the SCOUT-DX transmits the 2-kHz info 1w
towards the network, waiting for info 2.
