No access via web interface even though the amplifier was found.
The mDNS/Bonjour application shows a list which includes the amplifier with its name. By
opening the link the chosen amplifier doesn't show up its web interface.
If the IP-configuration of the TOPAS is not compatible with the rest of the network, an access
to the web interface is impossible.
Try to get the actual IP-address of the TOPAS.
After picking the non-accessable amplifier from the mDNS/Bonjour list by double-click, a new
window of your browser should open. On this page a message appears which says that the
right page could not be opened.
Now, you have to find out the IP-address of the actual shown page. Depending on your type
of browser the IP-address will be shown directly. Otherwise there's need for a little plugin
(e.g. ShowIP for Firefox) for your browser, which will display the actual IP-address.
A IP-address consists of 4 blocks with 3 digits each: ###.###.###.###
In order for two devices to communicate with one another (i.e. a TOPAS with a notebook),
the first six or nine digits must be identical, depending on the subnet mask.
Example 1: If you should have found out that your TOPAS e.g. has the IP-address
192.168.231.1 and the subnet mask is 255.255.255.0, the first three blocks have to be
identical with the IP-address (192.168.231.) with the ones of your client (notebook,
computer, tablet, etc.). For the last block you can choose any number between 0 and 255. It
has to be different from the ones of other devices in this network.
A subnet mask with the digits 255.255.0.0 means that you must only take over the first two
address triples.
Example 2: If you should have found out that your TOPAS e.g. has the IP-address 192.168.231.1
and the subnet mask is 255.255.0.0, the first two blocks have to be identical with the IP-address
(192.168.) with the ones of your client (notebook, computer, tablet, etc.). For the last two
blocks you can choose any number between 0 and 255. The last two blocks have to be different
from the ones of other devices in this network.
