3.4 Power Supply
The i-PORT M 350 RTLS is powered by the i-BUS.
Total Power Consumption—i-PORT M 350 RTLS with 4 i-SAT 300 RTLS
1 × i-PORT M 350 RTLS, app. 2 W
4 × i-SAT 300 RTLS, app. each 2 W
This gives a maximum sum of 7 W of power consumption.
3.5 Maximum Overall Cable Runs of i-BUS
There are 2 general limitations on the length of the i-BUS cabling:
• The overall length of the i-BUS over all units on the BUS must not exceed 1000 m (3000 ft)
• The distance from one unit to the next on the i-BUS must not exceed 300 m (1000 ft)
This tables is valid for Cat 5 cabling with gauge diameters of AWG24 (0.25 mm²).
