VME-7807RC 是一款6U 单插槽 VMEbus 模块，可为我们的嵌入式 VMEbus 处理器系列提供硬盘和软盘存诸选项。该模块可以单独配置一个驱动器，也可以同时配置两个驱动器。V1 80 301 8 303 2

闪存Q驱动器可作为选件提供。VME-7452 是无源VMEbus 板，仅连接到 P2 用户定义的引脚、电源和接地。标准 VMEbus 6U 单插槽外形3.5 英寸 1.44 MB 软盘动器可选闪存驱动器低电量其振幅仅取有限值的信号称为数字信号。数字信号是离散的，它们只包含不同的值。数字信号以位的形式携带二进制数据，即0或1，它在一段时间内只能包含一个值。数字信号表示为方波或时钟信号.最小值为0伏，而值为5伏。与模拟信号相比，数字信号较少受到噪声的影响。数字数据在模拟信道中的传输是通过一种称为调制的过程来完成的。振幅调制是使用单频载波信号将数字数据转换为模拟信号的过程。类似地，频移键控使用恒定振幅载波信号和两个频率来区分1和0。

The VME-7807RC is a 6U single-slot VMEbus module that provides hard and floppy storage options for our family of embedded VMEbus processors. The module can be configured with a single drive or two drives at the same time. V1 80 301 8 303 2

Flash Q drives are available as an option. The VME-7452 is a passive VMEbus board, connected only to P2 user-defined pins, power supply, and ground. Standard VMEbus 6U Single slot form factor 3.5 "1.44MB floppy disk driver Optional Flash drive Low power Signals with limited amplitudes are called digital signals. Digital signals are discrete, they only contain different values. Digital signals carry binary data in the form of bits, i.e., 0 or 1, which can only contain one value at a time. The digital signal is represented as a square wave or clock signal. The minimum value is 0 volts, while the value is 5 volts. Digital signals are less affected by noise than analog signals. The transmission of digital data over analog channels is done through a process called modulation. Amplitude modulation is the process of converting digital data into analog signals using a single frequency carrier signal. Similarly, frequency shift keying uses a constant amplitude carrier signal and two frequencies to distinguish between 1 and 0.
