Specifications

generates messages to non-existent or switched-off remotes (for any reason). When a remote site is
without power (including the RipEX) and the centre continues sending requests to that remote, the last
repeater will keep retransmitting these requests for full number of Retries set. More importantly, a long
retransmission time-out at the application level is not desirable any more, since it keeps the centre
from continuing the polling cycle. Nevertheless in any case it is beneficial to keep the number of applic-
ation retransmissions at the lowest setting available, i.e. zero if possible, and leave the RipEX network
to use the time available for the possible retransmitting.
To calculate the typical and maximum possible delivery time for different settings, please use the cal-
culator on Racom web pages, http://www.racom.eu/eng/products/ripex.html#calculation
The parameters discussed above are configured in the Router operating mode menu. Kindly see the
Help pages for further information.
