Function
Client
The radio will attempt to establish a TCP connection with the
specified remote unit. Generally, this setting is for the base station
with an Ethernet connection to the SCADA master.
Server
The radio will listen for a TCP connection on the specified local
port. Generally, this setting is for the remote radio with a serial
connection to the RTU.
Data received from any client shall be forwarded to the associated
serial port while data received from that serial port shall be
forwarded to every client with an open TCP connection.
If no existing TCP connections exist, all data received from the
associated serial port shall be discarded.
Client and Server
The radio will listen for a TCP connection on the specified local
port and if necessary, establish a TCP connection with the
specified remote unit. Generally, this setting is used for the
remote radio but it should be used carefully as two connections
might be established with the base station.
Data received from any client shall be forwarded to the associated
serial port while data received from that serial port shall be
forwarded to every client with an open TCP connection.
