Required Ip Ports - Danfoss AK-CS On Board Manual

AK-CS

required iP ports

As the AK-cs uses iP networking standards to create remote access it may be necessary to configure any site routers to allow incoming
connections, either from a lAn or WAn view. the figure below shows a simple iP connection with the AK-cs connected to a standard
network router with a typical factory iP address range. From within the lAn any remote connections should 'point' to the master iP
address of the AK-cs, in this example http://192.168.1.100. if however the remote connection is on a WAn then the lAn router may
need to be configured to allow this inbound connection, with the addition of the web port added tot he end of the http sting.
Please refer to the port allocation table below for remote iP connections
Master IP 192.168.1.100

Notes for FTP port forwarding in AK-SC255 units
in AK-cs units, FtP service is a convenient way to download/upload files and updating database/code. However, the AK-cs FtP functions
under 'passive' mode (which is a safer mode on the network), therefore ports 1024 to 4096 should be forwarded from the router to the
AK-cs unit if FtP access via WAn is used. this operation allows a wide range of port forwarding and may cause the other devices using
the same port for WAn access issues. Open FTP server ports to the public internet is not considered as a safe network practice. To
avoid these issues, Danfoss strongly suggests FTP functionality in LAN network only . This would reduce the risk of open FTP ports
and enhance network security.

lit. no.
1. the port number is required to be typed
into the Url address onlY if the web port is
not configured as 80. For example, if the port
number is configured as 8080, then computer
A needs to type in http://192.168.1.100:8080,
while computer B needs to type in
http://172.68.6.108:8080 to access the website
of the unit.
2. if the port number is defined as default
number 80, then it is not necessary to type in
":80" in the Url address, this is because the
HttP protocol uses 80 as default port. if the
router port forwarding is correctly configured,
it is not required in WAn access either.
