The MP-V controllers can be reconfigured to communicate with the hosting server based on the BACnet MS/TP protocol, instead of the BACnet/IP protocol. An adapter is required for converting the controller RS-485 Com port with RJ45 interface to screw terminals.
You wire the screw terminals on a Non-isolated RS-485 Adapter to connect an RP or MP controller to a BACnet MS/TP (RS-485) network or Modbus RTU (RS-485) subnetwork. Always use the recommended wires.
You connect a Non-isolated RS-485 Adapter (via a separate connection cable) to an RP or MP controller to convert the controller RS-485 RJ45 interface to screw terminals, which is required to connect the controller to a BACnet MS/TP (RS-485) network or a Modbus RTU (RS-485) subnetwork. You use a Non-isolated RS-485 Adapter (SXWNISORS48510001) when the BACnet MS/TP network includes non-isolated controllers, such as the b3 BACnet family of zone controllers, and when the Modbus RTU subnetwork includes Modbus devices that are non-isolated or isolated.
The Non-isolated RS-485 Adapter is equipped with an RJ45 port for connection to an RP or MP controller RS-485 Com port and a 4-position removable screw terminal block for connection to a BACnet MS/TP (RS-485) network or Modbus RTU (RS-485) subnetwork.
The Non-isolated RS-485 Adapter (SXWNISORS48510001) is used when connecting an RP or MP controller to the following networks:
You wire the screw terminals on an RS-485 Power Adapter to connect a BACnet/IP controller (RP or MP controller) to an RS-485 bus. Always use the recommended wires.
You wire the screw terminals on an Isolated RS-485 Adapter to connect a BACnet/IP controller to a BACnet MS/TP (RS-485) network. Always use the recommended wires.
This section provides recommendations on minimum wire sizes (cross-sectional areas) and maximum wire lengths for the wires connected to the screw terminals of Central IO modules, AS-B servers, RP and MP controllers, and IP-IO and RP-IO I/O modules. Recommendations on minimum wire size and maximum cable length for the digital inputs of the RP controller expansion modules, the DALI bus of the DALI light modules, the SMI Interface of the SMI blind modules, the Zigbee DALI and 0-10V modules, and the KNX Modbus gateway are also provided. The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.
The SpaceLogic Bluetooth Adapter allows you to establish a Bluetooth connection to SpaceLogic and EasyLogic controller models. To connect to a device through the SpaceLogic Bluetooth Adapter, a SpaceLogic Sensor must be wired to the controller.
It is important to perform the grounding correctly for the following reasons:
