MP-V Communication Ports

arrow1_rotationEthernet Ports arrow1_rotationUSB Ports arrow1_rotationRS-485 Port

The MP-V provides the following combination of communication ports:

  • Two Ethernet ports

  • Two USB ports

  • One RS-485 port

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. For more information, see BACnet/IP Controller Network Topologies . The second port also provides a connection point for a laptop running the Commission mobile application.

For more information, see 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 is reserved for future use.

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

For more information, see Communication Port Wiring .

RS-485 Port

Note:

The following description applies only for MP-V controllers with part numbers SXWMPV7AX10002 and SXWMPV9AX10002. For more information, see Differences Between MP-V Hardware Versions .

The RS-485 port is labeled:

  • RS-485 Com A

The RS-485 port is rated 2 W (24 VDC).

The RS-485 port is an RJ45 port. For more information, see RJ45 Pinout for the RS-485 Port of the MP-V Controller .

The RS-485 port can be configured to use one of the following two communication protocols for different types of networks:

  • Sensor bus

  • Modbus

The sensor bus is designed for communication with SpaceLogic Sensor devices. For more information, see MP-V Sensor Bus .

The Modbus (RTU) network can be used for communication with standard Modbus devices. For more information, see MP-V Modbus .

The RS-485 port can also be configured to support BACnet MS/TP network communication with the hosting server. For more information, see MP-V BACnet MS/TP Support .

For more information, see Allocating Flexible Ports .

The RS-485 port is by default configured to use the following network communication protocol:

  • Sensor bus
