Serial Interface
There are two serial ports in CSE-M32. Each port can be configured independently.
2.4.1
Serial Type
User can set RS232, RS422 and RS485 to CSE-M32‟s serial port. If CSE-M32 is configured
as RS485, the RTS pin operates as TXDE for RS485 line driver. (The TXDE is Low when CSE-
M32 doesn‟t send data to its serial port and High when CSE-M32 sends data to its serial
port.)
