Legends
Some noticeable fields and functions are explained below.
Port number
This is actually the port ID of each port. The application software will refer to the port by its port
number (ID). A duplicated port number is not allowed. That is, each MOXA serial port is referred
to as port number in terms of serial programming.
You may map the port number range to the one you prefer between 0 and 255, as long as no port
number overlapping condition or port number undefined condition occurs. Generally, you should
take the convenience of programming into consideration when specifying the port numbers for the
board.
TxD buffer size
The transmission (output) buffer allocated in the system for each port.
RxD buffer size
The receiving (input) buffer allocated in the system for each port.
F5 Group Edit
This is a convenient function that helps you edit the configuration of several ports at one time as a
group.
