If you ' re designing a keyboard , mouse , or host emulator , you should modify / sample the data line in the middle of each cell . i . e . 15 - 25 microseconds after the appropriate clock transition 如果你设计一个键盘鼠标或者主机模拟器,你必须在每个单元的中间时刻(也就是,在时钟跳变之后的15 25毫秒后)修改/取样数据线
If the optical fiber were brought directly into the cabinet , then it would be unnecessary to provide any data line or telecom protection , since there would not be a metallic pathway for transient voltage to enter into the equipment 如果光缆直接进入箱体内,则无须做任何数据线或信号线的保护,因为没有金属导体路径能让电涌电压进入到设备内部。
The company applies the most popular web system of the world , star lan structure , which can copy those critical equipment with double computers at the real time and link our system to other futures exchanges with complete ddn data lines 公司网络系统采用国际最流行的星型拓扑结构,关键设备采用双机实时备份,多条完备的ddn数据专线直接连接各期货交易所。
It is recommended that twisted pair wiring and coaxial cabling be provided with suitable data line protection , at the point where the signals penetrate the metal cabinet walls , with the protectors referenced to the metal cabinet by a short wire ( < 15cm ) 如果光缆直接进入箱体内,则无须做任何数据线或信号线的保护,因为没有金属导体路径能让电涌电压进入到设备内部。
This media can be used to provide quick - disconnect for auxiliary power for active i o modules , connect the data line from one device to another , provide input and output to blocks , and provide diagnostic , mechanical and electrical functions 的姐妹品牌,主要生产各种圆型连接器多端口接线盒mpis ,用于各种传感器电源线和信号线的现场快速可靠接插,省去了很多繁琐的配线。
