The RP-C provides the following combination of communication ports:
Two Ethernet ports
Two USB ports
Two RS-485 ports (RJ45)
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. Więcej informacji zawiera BACnet/IP Controller Network Topologies . The second port also provides a connection point for a laptop running the Commission 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 the 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. Więcej informacji zawiera 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 following description applies to RP-C hardware version 10 and later. Więcej informacji zawiera Differences Between RP-C Hardware Versions .
The two RS-485 ports are labelled:
RS-485 Com A
RS-485 Com B
The RS-485 Com A and Com B ports are both rated 3 W (24 VDC).
The two RS-485 ports are RJ45 ports. Więcej informacji zawiera 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. Więcej informacji zawiera RP-C Sensor Bus .
The room bus is designed for communication with RP controller expansion modules and multi-sensors for connected room solutions. Więcej informacji zawiera 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. Więcej informacji zawiera RP-C Modbus .
One of the RS-485 ports can also be configured to support BACnet MS/TP network communication with the automation server. Więcej informacji zawiera RP-C BACnet MS/TP Support . The other RS-485 port can then be configured to support either sensor bus, room bus, or Modbus network.
Default configurations:
Sensor bus on the RS-485 Com A port
Room bus on the RS-485 Com B port
