Table 4: Connection of the PWR supply connector
Power supply for router is required b10 V to +30 V DC supply. Protection against
reversed polarity without signaling is built into the router.
The power consumption during receiving is 1 W. The peak power consumption during data
sending is 5.5 W. For correct operation it is necessary that the power source is able to supply
a peak current of 1 A.
