| 摘 要： | 本文所介绍的IBM个人计算机多通道并行接口，能够在仅占用IBM个人计算机一个插槽和一个中断源情况下，经500米以上长线同时管理、并行驱动5台外围设备（打印机或显示器等），它不仅扩展了IBM个人计算机的硬件功能，而且增强了可靠性和抗干扰能力，使IBM个个计算机系统能够在工业生产环境下传送和处理信息。

| Abstract: | A parallel interface with multi-channels for IBM personal computer is presented. It only uses one slot and one interrupt source of an IBM personal computer. The interface circuit manages and drives five external devices, for example, printers or display units 500 meters and more away from the IBM personal computer.The expanded hardware capability and improved reliability and influence resistance enables the IBM personal computer system to transmit and deal with information pertaining to industrial production. |
