Power supply for the router must be b9 V to +36 V DC supply. Protection against
reversed polarity without signaling is built into the router. The router can be put into low power
mode using a special command
lpm
. Then it can be awakened by an activity on binary input or
using an internal timer. For more details of this command, see the application note
Commands
and Scripts
Upon power supply outage and subsequent renewal, the router is awakened!
