MS/TP Communication Adaptor, DTA118A72

The DIII-Net/BACnet MS/TP Communication Adaptor enables the connection of VRV systems to a compatible Building Management System (BMS). The adaptor operates as a BACnet router/gateway for the VRV system.  It will operate as a BACnet interpreter using services defined by BACnet to return the status of the indoor unit and outdoor units connected to the DIII network. The adaptor will also send commands to the indoor unit in response to the requests from the BMS. With this adaptor, a third-party BMS can monitor the VRV indoor units, outdoor units and control the indoor units through the BACnet MS/TP protocol. In addition, the adaptor can be mounted to the VRV outdoor or indoor unit.
