Communication Ports on RP-V-4A and -5A
The RP-V-4A and RP-V-5A models provide the following combination of communication ports:
Two Ethernet ports
One USB port
Two RS-485 ports (RJ45)
Ethernet Ports
The two Ethernet ports are labeled:
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. Более подробную информацию см. BACnet/IP Controller Network Topologies . The second port also provides a connection point for a laptop running the Commission mobile application.

USB Port
The USB port is labeled:
Host
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 controller. The adapter can be used to extend the controller's point count and bring flexibility in retrofit applications. Более подробную информацию см. Wireless Adapter - Advanced .

RS-485 Ports
The two RS-485 ports are labeled:
RS-485 Com A
RS-485 Com B
The RS-485 ports are rated for a maximum load of 3 W (24 VDC) per RS-485 port with a maximum total load of 4 W for the two RS-485 ports.
The two RS-485 ports are RJ45 ports. Более подробную информацию см. RJ45 Pinout for the RS-485 Port(s) of the RP-V Controllers .
Each port can be configured to use one of the following communication protocols for different types of networks:
Sensor bus
Room bus
Modbus
An RP controller can have only one of each network type.
The sensor bus is designed for communication with SpaceLogic Sensor devices. Более подробную информацию см. RP-V Sensor Bus .
The room bus is designed for communication with RP controller expansion modules for connected room solutions. Более подробную информацию см. RP-V Room Bus .
The Modbus (RTU) network can be used for communication with the KNX Modbus gateway (RP-C-EXT-KNX) and standard Modbus devices. Более подробную информацию см. RP-V Modbus .
One of the RS-485 ports can also be configured to support BACnet MS/TP network communication with the automation server. Более подробную информацию см. RP-V 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
