Legends
In this section, we explain the meaning of some of the fields and functions.
Port number
This is the ID of the port. Application software uses port number (ID) when referring to a port. You can set the
port numbers to any number between 0 and 255 (inclusive). However, you must ensure that you assign each
port a unique port number. If you are developing your own application software, then you may want to select
port numbers that take into consideration the structure of the program.
TxD buffer size
The TxD buffer is the transmission (output) buffer allocated by the system for each port.
RxD buffer size
The RxD buffer is the receiving (input) buffer allocated by the system for each port.
F5 Group Edit
