针对国内带ＧＰＩＢ接口仪器较少，不便于组建总线式自动测试系统的现状，利用８０Ｃ３２，ＰＳＤ３１１等单片机系统，设计了一种ＧＰＩＢ与ＲＳ２３２／４８５和并行口之间的转换器，使之能够将带ＲＳ２３２／４８５和并行口的仪器接入ＧＰＩＢ总线系统．实践结果表明：该转换器结构简单，功能完善，操作方便．
Aiming at the current situation that there are few instruments with GPIB interface in our country and it is inconvenient to set up a bus automatic test system, a single-chip microcomputer system such as 80C32 and PSD311 is used to design a converter between GPIB and RS232 / 485 and parallel port, Instrument with RS232 / 485 and parallel port access GPIB bus system. Practice shows that the converter has the advantages of simple structure, perfect function and convenient operation.
