Dhcp Setting - Elatec TCPConv 2 Technical Manual

3. Configuration with Web Frontend
Hostnames are composed of series of labels concatenated with dots, as are all domain
names. For example, "tcpconv.local" is a hostname. Each label must be between 1 and 63
characters long, and the entire hostname (including the delimiting dots) has a maximum of
255 characters. The Internet standards (Request for Comments) for protocols mandate that
component hostname labels may contain only the ASCII letters 'a' through 'z' (in a case-
insensitive manner), the digits '0' through '9', and the hyphen ('-'). (RFC 1123) permitted
hostname labels to start with digits. No other symbols, punctuation characters, or white
space are permitted.
For German language, this means umlauts (ä, Ä, ö, Ö, ü Ö, ) and ß are not allowed in
hostname.

3.1.1.2. DHCP Setting

One can also activate or deactivate the DHCP on a TCPConv 2 device. A static IP assign-
ment is also possible. If the device fails to get an IP address from DHCP server for some
reason, it will use 192.168.1.1 as default IP address.
3.1.2. USB Settings
Currently TCPConv 2 is able to handle HID and CDC readers. For CDC reader, one can
configure the communication parameters like baudrate, data bits, stop bits etc.
If the TCPConv 2 is configured as server, it is undesired that server port for USB and
for RS232 are the same, because USB server and RS232 server are two different pro-
cesses.
In the client section, one can configure when the client should be connected. If one wants to
specify the connect char, one should type in the decimal ASCII code for the character. This
rule also applies for "Disconnect on char". In Figure 3.4 for example, TCPConv 2 configured
in this way will be connected to the server, when the reader sends "0" to TCPConv 2 and it
will be disconnected when it receives carriage return from the reader.
3.1.3. RS232 Settings
The RS232 settings are quite similar to USB settings, as mentioned in last section. Currently
only server function is supported.
3.1.4. Load Default Settings
By pushing "Load Default Settings" one can view the default settings saved in database
on TCPConv. Note that this doesn't mean the settings are applied, in order to apply the
