Description: 单片机RS232/RS485串行发送实验（双机通讯）。
实验步骤：
（1），准备两台598K实验机，确定1号机为发送，2号机为接收；
（2），当作RS232接口实验时，1号机和2号机的P3.0和P3.1交叉相连，且两机共地；
（3），当作RS485接口实验时，1号机和2号机的A、B作对应连接，同时1,2号机的R/TEN接P1.0, P3.0接R0, P3.1接DI。
（4），先运行2号机，键入[27]-->[EV]使2号机处于接收状态P。，后运行1号机[26]-->[EV]使1号机处于发送状态,P。会闪烁，在1号机键盘上按动数字键，在2号机的数码管上应显示对应的数字键值。-Send Singlechip RS232/RS485 serial experiment (two-plane communications). Experimental steps: (1), prepare two sets of experiments 598K machine, determined on the 1st machine to send, on the 2nd machine to receive (2), as a RS232 interface experiment, on the 1st and the 2nd machine and P3.0 P3.1 cross-linked, and the two planes were to (3), as a RS485 interface experiment, on the 1st and the 2nd machine A, B for the corresponding connection, while 1,2 No. of R/TEN then P1 .0, P3.0 access R0, P3.1 then DI. (4), first run on the 2nd machine, type [27]

Description: 目前在工业控制领域,单片机系统主要通过RS232、RS485和CAN总线协议通信,它们无法直接与互联网连接,因此该系统处于与互联网隔绝的状态。这些系统广泛采用低成本8位单片机,而这种单片机一般只具有RS232异步串行通信接口,要接入到互联网必须进行通信接口改造,这种改造不仅是接口的物理改造,更关键是数据格式的改造和通信协议的转换。本文提出一种RS232串行通信接口与RJ45以太网接口转换器的设计方案,已有的单片机系统可以通过该转换器接入到以太网,进一步接入互联网。-Currently in the field of industrial control, single-chip microcomputer system mainly through RS232, RS485 and CAN bus protocol communications, they can not be directly connected to the Internet, so the system is in a state of isolation and the Internet. These systems are widely used in low-cost 8-bit MCU, which generally has a single-chip RS232 asynchronous serial communication interface, to access to the Internet must be communication interface transformation, such transformation is not only the physical interface transformation, more crucial is the transformation of data format and communication protocol conversion. In this paper, a RS232 serial communication interface with RJ45 Ethernet interface converter design, the existing single-chip microcomputer system via the access to Ethernet converter, and further access to the Internet.
