The NIRC3 can be powered directly from a Power over Ethernet (PoE 802.3af or 802.3at) switch or

through an external 24V DC power supply.

Details of the 24V DC power supply connections are given in 5.4.2, 2-Pole Connector Terminal

(NICT-2BA), page 33

The NIRC3 has two USB2.0HS host ports. Will be used in a future release to support WiFi functionality.

Note: The 4-pole and the 2-pole connector terminals required for the room bus and the 24V

power supply are not supplied with the room controller. The connectors are available as

accessories and must be ordered separately.
