Testing of the switching function
Press the push-button 1-4
The Link-LED does not light up
after the connection of the net-
work patch cable:
Check the network connection/patch cable
The TCR IP 4 can not be swit-
ched via the network
Use an IP-address that belongs to the subnet (the first three number blocks of the IP-address must be
identical).
Check the network settings. Enter the command ”ipconfig/all“under ”Start/Programs/Accessory/Com-
mand prompt”.
Switch off the Proxy-Server for local adresses
At the Internet Explorer: Type in an exception under ”Extra/Internet options/Connections/Lan-Connecti-
ons/Extended“ for the IP-address of the TCR IP 4 (z.B. 192.168.0.2)
Switching times will not be exe-
cuted as programmed

Switching
The TCR IP 4 can be operated
from the Internet, if certain pre-
conditions are fulfilled.
Every time you login to the Inter-
net, you start a new session and
receive from your provider an IP-
address.
Through this IP-address your
local network or PC can be iden-
tified from the internet for the
time of the connection to the in-
ternet.
With each new session you also
receive a new IP-address.
Permanent connections, i.e. in
case of a flatrate, will automati-
cally be disconnected after max.
24 hours and established again
with a new IP-address (dynamic
IP).
In order to always access the
TCR IP 4 or another IP-device
with the same address from the
internet, additional mechanism
must be activated. The TCR IP 4,
respectively, the IP-device re-
ceives a so called hostname
(freely selectable) which allows
the device to be found from the
internet. A provider translates the
hostname to the valid IP-address
during the actual session.
Following steps are necessary:
· A DNS-server (provider) for the
translation of the dynamic IP in-
to a host-name, i.e. free of
charge provider DynDNS
(www.dyndns.com).
· Optionally additional software
to ensure, that after an inter-
ruption of a session, the trans-
lation will be done again. This
software is also free of charge
and also available at the provi-
der (i.e. “DynDNS-updater” un-
der www.dyndns.com). Up-to-
date router and telephone sys-
tems perform this translations
by themselves.
1 Register at a dynamic DNS-
server of your choice.
2 Define a Hostname. Choose
a name that is easy to re-
member to make the dial-in
from the internet as easy as
possible.
3 Install, if required, the additio-
nal software (DNS update
client) on at least one PC wit-
hin the network to be acces-
sed. It is even better, if you
install the software on all PCs
that have access to the inter-
net. This guarantees that with
each connection of any PC to
the internet, the address
translation will automatically
be done.
4 Configure your router. First,
the corresponding port num-
ber for the remote access
must be defined and opened.
The router must know that te-
legrams must be directed to
the TCR IP 4 within the local
network via the requested
port number. The TCP-proto-
col is being used for the ope-
ration of the TCR IP 4, which
should be directed to the ad-
dress of the TCR IP 4
(default-address of the TCR
IP 4 = 192.168.0.2). In gene-
ral, port 80 is being used at
http.
This configuration will be
done at the DRMR from Ru-
tenbeck under item “virtual
server”. The port can be con-
figured at the KRR from Ru-
tenbeck as follows:
Firewall-Status
l
User defined
l
Internal Host
l
WAN-Port/LAN-Port
Procedure
The TCR IP 4 can be operated
from your mobile phone, if this
supports JavaScript.
Furthermore, all preconditions for
the switching from the internet
must be fulfilled.
