激光行业中及一些高精度需求的行业中关于硬件的介绍，包括软件的一些编译D A N G E R : This product contains potentially lethal voltages. To reduce the possibility of electrical shock, bodily injury, or death the following precautions must be followed. 1. Disconnect electrical power before servicing equipment. 2. Disconnect electrical power before performing any wiring. 3. Access to the Ndrive CP and component parts must be restricted while connected to a power source. 4. To minimize the possibility of electrical shock and bodily injury, extreme care must be exercised when any electrical circuits are in use. Suitable precautions and protection must be provided to warn and prevent persons from making contact with live circuits. 5. Install the Ndrive CP inside a rack or enclosure. 6. The shunt resistor temperature can exceed 70°C during normal operation and contains lethal voltage on its terminals and surface. It must be properly enclosed and shielded to avoid risk of fire and operator shock. 7. Do not connect or disconnect any electrical components or connecting cables while connected to a power source. 8. All components must be properly grounded in accordance with local electrical safety requirements. 9. Operator safeguarding

RS-422接口定义-通信 RS-422接口是一种单机发送、多机接收的单向、平衡传输规范，被命名为TIA/EIA-422-A标准。为扩展应用范围，EIA又于1983年在RS422接口基础上制定了RS-485标准，增加了多点、双向通信能力，即允许多个发送器连接到同一条总线上，同时增加了发送器的驱动能力和冲突保护特性，扩展了总线共模范围，后命名为TIA/EIA-485-A标准。由于EIA提出的建议标准都是以“RS”作为前缀，所以在通讯工业领域，仍然习惯将上述标准以RS作前缀称谓。
