TCP Server mode is default Link mode of Serial Settings, and it can wait for connecting requirement from

remote host PC which running “serial-to IP” utility or setting SW5002s in tunneling mode. User has to

number of hosts may open this port at the same time.

ATTENTION

When Max. Connections is greater than 1, the Serial server device will apply multi connection application

all hosts connected to the port must use identical serial settings. If one of the hosts opens the COM port

with different serial settings, data will not be transmitted properly
