本文介绍一种基于微型机并行打印接口的双向并行通讯技术。在不增加附加外设的条件下,采用这种技术构成的双机系统可以大于60000B/s的速度进行半双工的并行数字通讯。本技术对于多点的数字采集及控制系统具有较高的参考价值。
This article describes a parallel based on the parallel printer interface bi-directional parallel communication technology. Without adding additional peripherals, dual-system parallel digital communications can be performed at speeds greater than 60,000 B / s using dual-system systems of this technology. The technology for multi-point digital acquisition and control system has a higher reference value.
