Concept
RS-485 Adapters
The RS-485 adapters are RJ45 to screw terminal block adapters and are offered as accessories for some BACnet/IP controller models when the controllers are used in certain network configurations.
The RS-485 adapters are available in two models:
Isolated RS-485 Adapter (SXWISORS48510001)
Non-isolated RS-485 Adapter (SXWNISORS48510001)
The RS-485 adapters can be ordered from Schneider Electric using the above part numbers.
Isolated RS-485 Adapter
The Isolated RS-485 Adapter (SXWISORS48510001) is designed to be used when connecting a BACnet/IP controller that supports reconfiguration for BACnet MS/TP communication to a BACnet MS/TP (RS-485) network. The Isolated RS-485 Adapter has an isolated RS-485 transceiver and is used when the BACnet MS/TP (RS-485) network is comprised of isolated controllers, such as MNB BACnet devices (zone controllers) and selected others.
For more information, see Isolated RS-485 Adapter .
Non-isolated RS-485 Adapter
The Non-isolated RS-485 Adapter (SXWNISORS48510001) is designed to be used when connecting a BACnet/IP controller that supports reconfiguration for BACnet MS/TP communication to a BACnet MS/TP (RS-485) network. The Non-isolated RS-485 Adapter is used when the BACnet MS/TP (RS-485) network includes non-isolated controllers, such as the b3 BACnet family of zone controllers.
