开关主机和插卡是否兼容系统中的其它设备，以实现触发、控制及连接？
Are the switch mainframe and CARDS compatible with other equipment in the system with respect to triggering, controls, and connections?
在收集完这些信息后，就能够很容易地确定所需开关主机及开关卡的类型和数量。
Once this information has been gathered, determining the type and number of switch mainframes and CARDS required is straightforward.
大多数开关主机都可通过触发输入进行外部触发，并且在继电器触点稳定之后可输出一个触发脉冲。
Most switch mainframes can be triggered externally via the trigger input and can send an output trigger pulse when the relay contacts have settled.
