RipEX is always on, no special power saving modes are active.
Save Mode
When a RipEX is switched to the SAVE mode, it can be in one of two states – the SAVE
state or the ACTIVE state. In the SAVE state, the RipEX functionality is limited to listening
to the Radio channel in order to minimize the power consumption (approx. 2W). In the
ACTIVE state, the RipEX works normally, providing its full functionality (and consuming
normal amounts of power).
Transitions between these states can be controlled by changes at the SI pin on the Power
and Control connector, by receiving packets on the Radio channel and by values of the SAVE
mode configurable parameters.
The transition from the SAVE to the ACTIVE state requires system boot and takes approxim-
ately 48 sec. The transition from the ACTIVE to the SAVE state takes about 4 seconds.
SI hardware input (available from fw ver. 1.4.x.x)
When in the SAVE state, the RipEX wakes up (starts the transition to the ACTIVE state) after
a rising edge is registered at the SI hardware input (after the respective pin connection to
the ground has been opened). If a pulse is sent to the SI input (i.e. the falling edge follows
the rising edge), it has to be longer than 50 msec.
When in the ACTIVE state, the transition to the SAVE state starts when a falling edge is re-
gistered at the SI hardware input (the respective pin has been connected to the ground). The
falling edge triggers the transition only if the SI hardware input has been in the "high" state
(opened) for 2 seconds at least during the ACTIVE state of the RipEX. Following the falling
edge, the SI input has to stay in the "low" state (closed) at least for another 2 seconds.
Radio channel
RipEX is listening on Radio channel in the Save mode while consuming 2 W. It is woken up
when a packet is received over the Radio channel. However data from this first received
packet is lost.
Bridge mode: Any packet received on Radio channel wakes the unit up.
Router mode: RipEX is woken up when it receives a packet for its IP address. As "its IP" is
considered any IP address configured in this RipEX (Radio, ETH, ETH Subnet, SLIP.) or
