Communication Ports on MP-C-15A, -18A, -18B, -24A, and -36A
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. 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 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.

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. Более подробную информацию см. 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. Более подробную информацию см. MP-C Sensor Bus .
The Modbus (RTU) network can be used for communication with standard Modbus devices. Более подробную информацию см. MP-C Modbus .
