The “
On
” setting of this parameter disables any other assignment to the Hardware Alarm Output.
The “Unit ready” parameter cannot be activated in the Hot standby mode, since the Hardware Alarm
Output controls the Hot standby switch.
Power management
•
Power supply mode
List box: Always On, Save Mode, Sleep Mode
Default = Always On
•
Always On
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 approximately
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 registered
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 con-
sidered any IP address configured in this RipEX (Radio, ETH, ETH Subnet, SLIP.) or any IP address
routed through this RipEX. I.e. RipEX is woken up not only with packets which end in it, but also
with packets which end in the connected device behind RipEX or which are relayed over the Radio
channel (when this RipEX is configured as the Repeater for them).
When an unexpected reboot happens while in the ACTIVE state, the RipEX enters the ACTIVE
state again and the “Timeout from wake-up” is reset. When a reboot happens while in the SAVE
state, the RipEX enters the SAVE state immediately after the reboot.
When one of the configurable parameters is changed while the RipEX is in the ACTIVE state, the
“Timeout from wake-up” is reset.
○ Timeout from wake-up [s]
Default = 300 (min. 60, max. 64800)
RipEX stays ACTIVE for the set time from the moment of its wake-up. When this timeout expires,
the RipEX switches back to the SAVE state.
