4.5.4. UDP Mode
STW-602C can be configured in a
UDP mode
to establish connection using
Unicast
or
Multicast
data from
the serial device to one or multiple host computers. Vice versa is also true. For example, the original
RS-422/ RS485
bus can be transferred and extended connected distance by STW-602Cs.
The destination IP is assigned by single IP or group IPs, The configuration is limited by the Local Listening
Port. For example, on STW-602C listening port is 4660 which receive data sending from the host computers.
STW-602C can support up to
4-group
IPs for UDP connection, if users needed.
