TCP Client Mode
UDP Mode：UDP is a fast but non-guaranteed datagram delivery protocol. GW51C-MAXI Serial Server
can be configured in a UDP mode on a TCP/IP Network to establish a connection, using unicast or
broadcast data to and from a serial device to one or multiple host computers (UDP Mode)
UDP Mode
Tunneling Mode(Pair Connection)：The tunneling mode is used for multiple serial devices to “talk” to
each other through GW51C-MAXI Serial Server’s and their Ethernet connections (Tunneling Mode). This
mode is particularly useful when two serial devices are far away, because their communication distance is
limited to 15 m.
