BACnet port
For communication with the controller network using BACnet ARC156 (156
kbps) or BACnet MS/TP (9600 bps – 76.8 kbps)
Rnet port
•
Supports up to 15 wireless and/or ZS sensors, and one Equipment Touch or
TruVu™ ET Display
•
Supplies 12 Vdc/210 mA power to the Rnet at an ambient temperature of
77°F (25°C) with a 24 Vac nominal power source.
NOTE Ambient temperature and power source fluctuations may reduce the
power supplied by the Rnet port.
NOTE
If the total power required by the sensors on the Rnet exceeds the power
supplied by the Rnet port, use an external power source. The Wireless Adapter,
Equipment Touch, or TruVu™ ET Display must be powered by an external power
source. See the specifications in each device's Installation and Start-up Guide to
determine the power required.
