2.产 品 详 情 资 料：
NI PXI-6259必须将适当的终端电阻器连接到总线的始端和末端。表142列出了每种类型电缆的特性阻抗。如果CI862位于总线两端，则通过现场总线接口模块上的开关设置特性电阻，见表17。如果TRIO模块位于总线的起点或终点，则可以使用电阻器或端接电阻插头（6202FP00150（150 W）或6202FP00075（75 W））端接总线。BSM短截线不应端接。从正面看时，双列直插开关位于外壳底部。开关1朝向外壳顶部。安装Satt I/O单元和NI PXI-6259由处理器单元通过CEX总线供电，不需要额外的外部电源。NI PXI-6259没有为现场设备供电。使用以下步骤将ControlNet连接到I/O系统和CI865模块的BNC连接器。有关更多信息，请参阅AC 800M的Satt I/O接口（3BSE042821*）。BNC连接器位于：•机架I/O-200-RACN模块后部。•200系列I/O-位于200-ACN模块的前部。•CI865-位于NI PXI-6259模块的前部NI PXI-6259
The appropriate terminating resistor must be attached to both the beginning and end of the bus. The characteristic impedance for each type of cable is listed in Table 142. If theNI PXI-6259is at either end of the bus, the characteristic resistance is set by a switch on the Field Bus Interface Module, Table 17. If a TRIO module is at the beginning or end of the bus, the bus can be terminated with a resistor or a terminating resistance plug, 6202FP00150 for 150 W or 6202FP00075 for 75 W. BSM stubs should not be terminated.the dip switch is located on the bottom of the housing when looking from the front. Switch 1 is towards the top of the housing.Installing the Satt I/O Units and CI865 Module The NI PXI-6259is powered from the processor unit via the CEX-Bus and requires no additional external power source. No field device is powered from the NI PXI-6259. Use the following procedure to connect the ControlNet to the BNC connector of the I/O systems and the NI PXI-6259 module. For more information see Satt I/O Interface for AC 800M (3BSE042821*). The BNC connector is located: • Rack I/O - at the rear of the 200-RACN module. • Series 200 I/O - at the front of the 200-ACN module. • CI865 - at the front of the CI865 module
