RP-C Communication Ports

arrow1_rotationEthernet Ports arrow1_rotationUSB Ports arrow1_rotationRS-485 Ports

The RP-C provides the following combination of communication ports:

  • Two Ethernet ports

  • Two USB ports

  • Two RS-485 ports

Ethernet 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. Pour plus d'informations, voir BACnet/IP Controller Network Topologies . The second port also provides a connection point for a laptop running the eCommission SmartX Controllers mobile application.

Pour plus d'informations, voir Communication Port Wiring .

USB Ports

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. Pour plus d'informations, voir Wireless Adapter - Advanced .

The USB device port is a USB 2.0 mini-B port. The USB device port is reserved for future use.

Pour plus d'informations, voir Communication Port Wiring .

RS-485 Ports

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. Pour plus d'informations, voir 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

Déclaration

An RP-C can have only one of each network type.

The sensor bus is designed for communication with SpaceLogic Sensor devices. Pour plus d'informations, voir RP-C Sensor Bus .

The room bus is designed for communication with RP controller expansion modules and multi-sensors for connected room solutions. Pour plus d'informations, voir 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. Pour plus d'informations, voir 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)
