The RP-C provides the following combination of communication ports:
Two Ethernet ports
Two USB ports
Two RS-485 ports
The two Ethernet ports are labelled:
Ethernet 1
Ethernet 2
The two Ethernet ports are 10/100BASE-TX (RJ45) ports. When both Ethernet ports are enabled, they function as an onboard Ethernet switch. Disabling the second Ethernet port disables the switching function. The switching function enables flexible network topologies. Für weitere Informationen siehe BACnet/IP Controller Network Topologies . The second port also provides a connection point for a laptop running the eCommission SmartX Controllers mobile application.

The two USB ports are of different types:
USB host port
USB device port
The USB host port is a USB 2.0 type-A port, which is rated 2.5 W. The USB host port can be used for connection of Wireless Adapter - Advanced to add Zigbee TM wireless connectivity to the RP-C controller. The adapter can be used to extend the controller's point count and bring flexibility in retrofit applications. Für weitere Informationen siehe Wireless Adapter - Advanced .
The USB device port is a USB 2.0 mini-B port. The USB device port is reserved for future use.

The two RS-485 ports (RS-485 Com A and Com B) are labelled:
Sensor Bus
Room Bus
The Sensor Bus port (RS-485 Com A) is rated 2 W (24 VDC). The Room Bus port (RS-485 Com B) is rated 3 W (24 VDC).
The two RS-485 ports are RJ45 ports. Für weitere Informationen siehe RJ45 Pinout for the RS-485 Ports of the RP-C Controller .
Each port can be configured to use one of the following three communication protocols for different types of networks:
Sensor bus
Room bus
Modbus
An RP-C can have only one of each network type.
The sensor bus is designed for communication with SpaceLogic Sensor devices. Für weitere Informationen siehe RP-C Sensor Bus .
The room bus is designed for communication with RP controller expansion modules and multi-sensors for connected room solutions. Für weitere Informationen siehe RP-C Room Bus .
The Modbus (RTU) network can be used for communication with the KNX Modbus gateway (RP-C-EXT-KNX) and standard Modbus devices. Für weitere Informationen siehe RP-C Modbus .
Default configurations:
Sensor bus on the Sensor Bus port (RS-485 Com A)
Room bus on the Room Bus port (RS-485 Com B)
