PC与Trane CH530控制器的长距离通讯方案

摘要

This paper introduces a long distance RS232 communication between Trance CH530 control er and PC,it also can be used for other long distance RS232 communication requirement,but should change the line-connection depend on device.%介绍PC与Trane CH530控制器的长距离通讯方案及具体实现方法。该方案也可用于类似的有长距离RS232串行通讯要求的场合，在实际应用中需要根据终端设备调整交叉线的接线方法。
