BEMTLY 3500/22M带有TDI 的框架接口模块
导电底盘导轨连接至接地。这提供将屏蔽连接到接地的路径。前面板螺钉正确拧紧。对于最小射频发射，必须满足上述条件实施；如果不这样做，可能会危及FCC包含模块的设备的合规性。表1-3。MVME147规格特性规范功率要求（MVME147，带两个EPROM和MVME712M）+5 Vdc，最大4.5A（典型值为3.5 A）+12 Vdc，最大1.0 A（最大100 mA-无LAN）-12 Vdc，最大100 mA注意：电源必须从P1和P2引入背板

Conductive chassis rails connected to earth ground. This provides the path for connecting shields to earth ground. 4. Front panel screws properly tightened. For minimum RF emissions, it is essential that the conditions above be implemented; failure to do so could compromise the FCC compliance of the equipment containing the modules. Table 1-3.
