EtherWave - WMR
6.0 Configuration
IP Protocol Config
This setting determines which protocol the serial server will use to
transmit serial port data over the EtherWave-WMR network.
TCP Client:
When TCP Client is selected and data is received on
its serial port, the EtherWave-WMR 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 EtherWave-
WMR 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 EtherWave-WMR 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 COM

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.
