NI PXIe-1085兩個(gè)M3指旋螺釘將設(shè)備固定到其配合連接器上。該設(shè)備可以很容易地插入到現(xiàn)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?；蛘?，隔離器可以使用提供的延長電纜與PLC系統(tǒng)分開安裝。為了單獨(dú)安裝到面板上，您需要提供兩個(gè)#6-32（4 mm）安裝螺釘（圖E-3）。安裝隔離器時(shí)，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(diǎn)配置（圖E-4）。有關(guān)安裝信息，請參閱《串行通信用戶手冊》（GFK-0582）第3節(jié)。用戶手冊中未涵蓋的一種配置是隔離器由主機(jī)端口以外的電源供電的情況。NI PXIe-1085如果主機(jī)系統(tǒng)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(shè)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
