1·PowerCommand Networks use Manchester Encoding that makes the signal insensitive to polarity. The signal is transformer-coupled to the network data wire at a rate of 78 KBPS.

PowerCommand网络利用Manchester编码使信号不受极性影响，信号通过变压器传送到网络数据线的速度是78 KBPS。

2·The paper describes the design of encoder which is divided into seven modules: bit control unit, FIFO unit, frame delimiter unit, data conversion unit, CRC unit, Manchester encoding unit.

论文介绍了多功能总线控制器编码器的设计，编码器有六个模块组成，分别为位控制单元、FIFO单元、帧分界符单元、数据转换单元、CRC校验单元和曼彻斯特编码单元。
