DSE857
USB to RS485 Communications Device
The DSE857 communications device allows monitoring of a single DSE controller with USB connectivity by converting it to an RS485 connection. To achieve this the DSE857 connects to an RS485 MODBUS RTU master over 1.2km away. The MODBUS RTU master can be an external PLC, Building Management System (BMS) or a Windows PC running the DSE Configuration Suite Software.
