Westermo ED-10 TCP - Manual (Page 29)

29 6609-2211
7.3.3. Network interface
Local IP address*
Local IP address is used as the first part of local end point identity, in both application
and configuration mode. Do not use Network ID or Broadcast address.
Default is 10.0.0.10.
Local Protocol Port*
The protocol port is the second part of a end point identity. This local TCP port is used
only in application mode. The remote client (computer) must address this local port to
establish a TCP connection.
Allowed values are 1–20, 22, 24–79, 81 - 65535 (>1024 recommended). Port 23 shall
be used for configuration and status information. Port 21 and 80 can not be used.
Please observe that ports 1–1024 are “well-known ports”, hence commonly used by
other programs (e.g. FTP, Telnet, NETBIOS, mail etc). “well-known ports” should
normally not be used by ED-10 TCP. All ”well-known” ports can be found at
http://www.iana.org/assignments/port-numbers
Default is 9000.
Remote IP address*
Required IP address of remote client (computer). The ED-10 TCP will only accept con-
nections (clients) with the Remote IP address. Remote IP address 255.255.255.255 will
force the ED-10 TCP to accept any (all) connections.
An established connection will be closed by a new connection request, if the Remote IP
address is set to 255.255.255.255.
If the Remote IP not are equal to 255.255.255.255 an established connection will remain
established and any new connection requests will be refused.
Default is 255.255.255.255.
Remote Protocol Port
The remote protocol port is not used, hence ignored.
Netmask*
The Netmask is used for Subnet addressing.
Default is 255.255.255.0.
* The IP address must be compliant to the attached network. Ask the network administrator when
in doubt.
