3.2. Socket B Communication
USR-N540 support double socket communication mode, socket A and socket B. One serial port corresponding to
two socket communication mode can be realized through setting the parameter of socket B.
Notes: socket B is only used for transparent transmission and only worked as TCP client or UDP client.
Set USR-N540 as double socket communication mode, the data of serial port will be transparently transmitted to
socket A and socket B at one time. When data comes from socket A and socket B simultaneously, USR-N540 will
transmit the data of socket A to serial port firstly, and then transmit the data of socket B once the data of socket A
finished.
