The Non-isolated RS-485 Adapter (SXWNISORS48510001) is used when connecting an RP or MP controller to the following networks:

  • BACnet MS/TP (RS-485) network including non-isolated controllers

  • Modbus RTU (RS-485) subnetwork including Modbus devices

Figura: Non-isolated RS-485 Adapter

The adapter converts the controller RS-485 Com port RJ45 interface to screw terminals, which is required to be able to connect the controller to a BACnet MS/TP or Modbus RTU subnetwork.

A separate connection cable is required to connect the adapter to the controller. The cable is not included and needs to be purchased separately.

BACnet MS/TP network including non-isolated controllers

The Non-isolated RS-485 Adapter is used when connecting an IP based RP or MP controller (BACnet/IP controller) to a BACnet MS/TP network that includes non-isolated controllers, such as the b3 BACnet family of zone controllers.

The adapter can be used with BACnet/IP controller models that support reconfiguration for BACnet MS/TP communication. Para obtener más información, consulte Adaptadores RS-485 SpaceLogic .

The BACnet/IP controller needs to be reconfigured to communicate with automation servers based on the BACnet MS/TP protocol, instead of the BACnet/IP protocol. Para obtener más información, consulte Allocating Flexible Ports .

Modbus RTU subnetwork including Modbus devices

The Non-isolated RS-485 Adapter is used when connecting an RP or MP controller to a Modbus RTU subnetwork that includes Modbus devices that are non-isolated or isolated.

The adapter can be used with RP and MP controller models that support Modbus RTU communication. Para obtener más información, consulte Adaptadores RS-485 SpaceLogic .

One of the controller's RS-485 port(s) needs to be configured for Modbus RTU communication. Para obtener más información, consulte Allocating Flexible Ports .

RS-485 Adapter Device Installation

The RS-485 adapter has a protruding bracket on each long side with a mounting hole to facilitate installation of the device with two screws (not included). The device can also be fastened using cable ties or mounted in line with a cable run. The RS-485 adapter is suitable for plenum use.

Non-isolated RS-485 Adapter Connection and Wiring

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.
