Note : see your printer documentation for specific instructions on connecting the usb or parallel cable to your printer and computer 注意：按照打印机说明书把你的打印机通过usb或者并行数据线连接在电脑上。
A good rule of thumb is if the propagation delay of the data line is much less than one bit width , termination is not needed 一个好经验法则是：如果数据线的传播延迟远小于一个位宽度时,就不必使用终端电阻。
The 2 - wire interface is a widely used master , multi - slave protocol using a serial clock ( scl ) and a serial data line ( sda ) 此2线接口是一个广泛使用的主机、使用串行时钟（ scl ）和串行数据线（ sda ）的多从机协议。
Directly or through transmission lines to the data folder , then choose a direct function of the game that can be activated Menu - games文件夹，或通过数据线直接传输至该文件夹，然后在游戏功能中直接选择启动即可。
In a particularly " noisy " electronic environment this problem might be solved by the use of fiber optic lines to convey digital signals 在有些特殊的电磁干扰环境下，应该通过使用光纤维数据线来传输数字信号，从而避免干扰问题。
The host changes the data line only when the clock line is low , and data is read by the device when clock is high 只有当时钟线为低的时候，主机才可以改变数据线（也就是将数据写入到数据线） 。数据将在时钟为高电平的时候被设备读取。
The only access points for transients are via the ac or dc power line wires and all of the data and telcom signal wiring that enters and leaves the cabinet 电涌的唯一进入通道是交流或直流电源线及所有进出金属箱的数据线和信号线。
After the stop bit is received , the device will acknowledge the received byte by bringing the data line low and generating one last clock pulse 只有当时钟线为低的时候，主机才可以改变数据线（也就是将数据写入到数据线） 。数据将在时钟为高电平的时候被设备读取。
Lcd will display wanted data by writing data to specified instruction register and specified data register through control bus and data bus , which makes operation easier 只要通过数据线和控制线对指定的寄存器进行操作即可对想要显示的数据进行显示，开发起来很容易。
The siemens mobile telephone with the gsm modem is controlled by the at command through the mobile telephone data line between the signal chip system and the serial interface of the mobile telephone 通过手机数据线连接单片机系统和手机串口，对西门子手机内置的modem进行指令控制。
