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

  • Two Ethernet ports

  • Two USB ports

  • One RS-485 port

This applies to the following MP-C models without “-M” in the product name:

  • MP-C-15A, MP-C-18A, MP-C-18B, MP-C-24A, and MP-C-36A

Ethernet Ports

The two Ethernet ports are labeled:

  • Ethernet 1

  • Ethernet 2

The two Ethernet ports are 10/100BASE-TX (RJ45) ports.

The Ethernet interface is IEEE 802.3 compliant.

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. Per maggior informazioni, consulta BACnet/IP Controller Network Topologies . The second port also provides a connection point for a laptop running the Commission mobile application.

Per maggior informazioni, consulta 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.

Per maggior informazioni, consulta Communication Port Wiring .

RS-485 Port

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. Per maggior informazioni, consulta RJ45 Pinout for the RS-485 Port of the MP-C 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. Per maggior informazioni, consulta MP-C Sensor Bus .

The Modbus (RTU) network can be used for communication with standard Modbus devices. Per maggior informazioni, consulta MP-C Modbus .

Per maggior informazioni, consulta Allocating Flexible Ports .

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

  • Sensor bus
