standard interface bus

USB(Universal Serial Bus) interface is a newly bus interface standard. It has flexible power supply mode, very high transfer rate and plug and play virtue.

接口是一种新兴的总线接口标准，它具有灵活的供电方式、较高的传输速率和即插即用等优点。

The batch controller also has a standard interface of RS-485 bus, preferably achieved the network design of the batch control system.

该配料控制器还配有标准的RS—485总线接口，较好地实现了配料控制系统的网络化设计。

As a try for circuit standardization, the system realizes the standard protection circuit unit and recovering-time circuit unit, which are connected to system through standard 44 pins' bus interface.

作为标准化的尝试，本系统实现了标准的保护电路单元和恢复时间电路单元，通过44芯总线插座与标准总线接口连接。
