我有一个 RS485 输出，但我不知道它使用的是哪个字符集
I have an RS485 output but I don't know which character set it is using
输出字符串为：
▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒~▒▒ffx▒f▒x▒x`▒x▒x▒x▒`▒x~x▒▒x▒▒x````▒````▒x~xx▒x▒f`▒x▒
而且我知道通过 RS232 输出应该类似于：
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿSITE NAME,24/07/18,13:15:00,60,0.000,0.000,2.911,2585,
时间可能会改变，最后两个数字也可能会改变，但字符串的其余部分应该保持一致。有没有办法找出使用的字符集？
在RS-485 Wikipedia中是这样写的
Protocols
RS-485 is not a protocol; it's simply an electrical interface. Although many applications use RS-485 signal levels, the speed, format, and protocol of the data transmission is not specified by RS-485. Interoperability of even similar devices from different manufacturers is not assured by compliance with the signal levels alone.
如果您尝试连接的设备的规格没有记录，您只能使用示波器等测量仪器进行查找？
