2.產 品 詳 情 資 料：
NI PXIe-1085兩個M3指旋螺釘將設備固定到其配合連接器上。該設備可以很容易地插入到現有的通信信道中，而無需額外的硬件。在圖E-2中，隔離器顯示為直接連接到CPU模塊。或者，隔離器可以使用提供的延長電纜與PLC系統分開安裝。為了單獨安裝到面板上，您需要提供兩個#6-32（4 mm）安裝螺釘（圖E-3）。安裝隔離器時，將連接器螺釘和面板安裝螺釘（如果使用）擰緊至以下扭矩值：NI PXIe-1085RS485端口隔離器支持端口對端口和多點配置（圖E-4）。有關安裝信息，請參閱《串行通信用戶手冊》（GFK-0582）第3節。用戶手冊中未涵蓋的一種配置是隔離器由主機端口以外的電源供電的情況。NI PXIe-1085如果主機系統需要重新通電，該配置用于防止通信中斷。它還可以防止使用端口供電的設備斷電。NI PXIe-1085
Two M3 thumbscrews secure the device to its mating connector. The device can be easily inserted into an existing communication channel with no additional hardware. In Figure E-2, the Isolator is shown connected directly to a CPU module. NI PXIe-1085Alternatively, the Isolator can be mounted separately from the PLC system using the extender cable provided. For mounting separately to a panel, you will need to provide two #6-32 (4 mm)mounting screws (Figure E-3).NI PXIe-1085When installing the Isolator, tighten the connector screws and panel mounting screws (if used) to the following torque values:The RS485 Port Isolator supports both port-to-port and multi-drop configurations (Figure E-4). For installation information, refer to section 3 of the Serial Communications User's Manual (GFK-0582). One configuration not covered in the User's Manual is the case where the Isolator is powered by a source other than the host port. This configuration is used to prevent an interrupt in communications if the host system requires a power cycle. It also prevents power loss to equipment using the port for power.NI PXIe-1085
