NI PXI-2593多路复用器开关模块中文资料：
NI PXI-2593多路复用器开关模块CPU350和CPU360硬件功能这两个模块除了标签外看起来完全相同。这些模块具有一个LED灯，标记为“PS端口”，通过PLC电源上的串行连接器指示串行端口活动。通常，当通过端口传输数据时，此LED将闪烁，当端口处于非活动状态时，此指示灯将熄灭。Ŷ这些模块还具有本章前面所述的按键开关，这是350–364 CPU的标准配置。CPU固件升级存储在闪存中的CPU固件通过PLC电源上的串行端口连接器加载。CPU351、CPU352和CPU363硬件功能这三个模块的功能和功能相似。CPU351和CPU352看起来完全相同，只是标签不同。CPU363具有与其他两个相同的功能，但其端口1和端口2连接器的方向与CPU351和CPU352的方向相反，其LED指示灯、按键开关和屏蔽接地连接器位于不同的位置。（屏蔽接地连接器位于CPU363的前面板上，标有“FRAME”，但位于CPU351和CPU352模块的底部。）NI PXI-2593

CPU350 and CPU360 Hardware Features These two modules look identical except for labeling.These modules feature an LED light, labeled “PS Port” that indicates serial port activity through the serial connector on the PLC power supply. Typically, this LED will flash while data is being transferred through the port, and will stay off when the port is inactive. Ŷ These modules also have the keyswitch, described earlier in this chapter, that is standard on the 350–364 CPUs. CPU Firmware UpgradeNI PXI-2593The CPU firmware, which is stored in Flash memory, is loaded through the serial port connector on the PLC Power Supply.CPU351, CPU352, and CPU363 Hardware Features These three modules are similar in features and functionality. The CPU351 and CPU352 look identical except for labeling. The CPU363 has the same features as the other two, but the orientation of its Port 1 and Port 2 connectors is reversed from those of the CPU351 and CPU352, and its LED indicator lights, key switch, and shield ground connector are in different locations. (The shield ground connector is on the front panel of the CPU363, labeled “FRAME,” but is located on the bottom of the CPU351 and CPU352 modules.)NI PXI-2593
