IP9xx Series
6.0 Configuration
IP Protocol Config
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
unit when the data exchange session is completed and the
connection timeout has expired. If a TCP connection cannot be
established, the serial port data is 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
connection is in an idle state (i.e. no data traffic on the
serial port).
Default: 60 (seconds)
TCP Server: In this mode, the IP Series will not INITIATE a
session, rather, it will wait for a Client to request a session of it (it‘s
being the Server—it ‗serves‘ a Client). The unit will ‗listen‘ on a
specific TCP port. If a session is established, data will flow from the
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.
 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

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