6.0 Configuration
The protocol selected in the
IP Protocol Config field will
determine which configuration
options appear
remainder of the
Configuration Menu.
UDP: User
Protocol does not provide
sequencing information
the packets sent nor does it
e s t a b l i s h
'connection' (‗handshaking')
and is therefore most suited
to communicating
packets of data.
TCP: Transmission Control
Protocol in contrast to UDP
does provide
information and is connection-
oriented; a more
protocol, particularly
large amounts of data are
being communicated.
Requires more
than UDP.

This setting determines which protocol the serial server will use to
transmit serial port data over the IP Series network.
TCP Client: When TCP Client is selected and data is received on
its serial port, the IP Series takes the initiative to find and connect to
a remote TCP server. The TCP session is terminated by this same
in the
unit when the data exchange session is completed and the
COMn
connection timeout has expired. If a TCP connection cannot be
established, the serial port data is discarded.

Client to the Server, and, if present, from the Server to the Client. If
a session is not established, both Client-side serial data, and
Server-side serial data , if present, will be discarded.


Remote Server Address
IP address of a TCP server which is ready to
accept serial port data through a TCP connection.
For example, this server may reside on a LAN
network server.
Default: 0.0.0.0

Remote Server Port
A TCP port which the remote server listens to,
awaiting a session connection request from the
TCP Client. Once the session is established, the
serial port data is communicated from the Client to
the Server.
Default: 20001

Outgoing Connection Timeout
This parameter determines when the IP Series will
terminate the TCP connection if the
in an idle state (i.e. no data traffic on the
port).
Default: 60 (seconds)
In this mode, the IP Series will not INITIATE a

Local Listening Port
The TCP port which the Server listens to. It allows
a TCP connection to be created by a TCP Client to
carry serial port data.
Default: 20001
