2.1.4 TCP Client Mode

In TCP Client mode, the TCP connection will be established from EKI serial device

server. This operation mode supports maximum four simultaneous connections for

each serial port on EKI-1321/1322 to one host or several hosts. You should configure

the IP address and TCP port number of the network hosts which the EKI serial device

server connect to using Advantech Serial Device Server Configuration Utility. After

configuration, when EKI serial device server receives the data from serial port, the

device server will employ the connection to hosts which are configured.
