1.This controller bypass command from COM1 to COM3. COM3 bypasses the response to COM1. The response contains COM3 address. and vice versa.
2.This 7522 controller doesn't support ring buffer of 232 port.
3.Each command or response characters can't exceed 251 characters.
4.$AAR (via COM2: RS-485) can reset the command-response pair of two RS232 port(COM1,COM3).
5.There are 3 response mode:com1,com3 and 485.
6.Whichever 232 port recesives the string which is a vaild command for that port, right away the controller sets that port as a command-port, the other 232 port as a recesive- port, at the same time, bypass this string.
7.The command-port will determine if the command will be bepassed or not.
8.If the string which is recesived by recesive-port is not a valid command for that port, the controller will bypass the string to the other command 232 port or COM2 according to the response mode. The recesive-port address will be added if the string is going to pass to the command-port.
