terminal programs you intend to use. From now on, as long as your Bluetooth manager is
operating, starting and terminating the terminal program will also start or terminate the
Bluetooth connection between the modem and the PC. From now on you’re wireless.
Many current Bluetooth sticks come with the Bluetooth manager software
BlueSoleil
. A step-
by-step introduction for this manager with screenshots can be downloaded from our homepage.
5.4 Ethernet
The computer connection to the
P4
dragon
can also be established via Ethernet (10Base-T or
100Base-T), provided the Network option (Linux computer module DNP) is installed inside. If
this is the case you can see in the Status window of the display, just below the Bluetooth key.
Easily connect the
P4
dragon to your router, switch or hub using a general purpose patch cable.
The
P4
dragon
is able to accept his IP-address assigned by DHCP. If you don’t have a DHCP
server in your network you need to configure the
P4
dragon to use a fixed IP-address. This
choice is done using the DIP switch #3 labeled
DHCP
on the back side of the
P4
dragon
. DHCP
is
off
then the switch is in the upper position and
on
when in lower position. With DHCP off,
the default IP-address then is
192.168.0.100
and Netmask
255.255.255.0
.
The configuration of the
P4
dragon
then continues with the help of a comfortable web-interface.
Here you can change all important settings as well as the IP-address.
The web-interface is mainly self explaining. For every item an online help is available. Just
click on the name of the item you require help for.
You connect the web-interface of your
P4
dragon
by entering the IP address as URL into your
preferred web browser, e.g. http://192.168.0.100 . The user name is “
root
” and the password is
“
DR7800
”.
5.4.1 Using the SER2NET feature of the
P4
dragon
The SER2NET feature allows the
P4
dragon
to be used as a "quite normal" PACTOR modem
via a network connection. PACTOR modems can be used with simple terminal programs, or
programs for special applications like eMail or FAX. All this programs are made to access the
modem via a serial connection, a COM port. The SER2NET feature “tunnels” the serial data
connection of the modem as TCP/IP through the Ethernet connection and makes it available to
a special SER2NET driver, which must be running on the PC that wants to access the modem.
This SER2NET driver creates a virtual serial com port, as it is well known from USB adapters
or the USB/Bluetooth connection of the
P4
dragon
. This virtual COM port number is entered
into the program(s) used to access the
P4
dragon
. From now on everything runs as normal and
the
P4
dragon
behaves the same way as connected via USB or Bluetooth.
Using SER2NET feature brings several viewpoints to the operation of a PACTOR modem at
all. For the easiest application, it is enough to connect the
P4
dragon
with the network connector
of a local PC. But as a networking device, the
P4
dragon
can also be connected at any possible
location in the network (or the Internet) and can be operated from a PC which is located
elsewhere in the local network, or Internet. The exciting fact is, that the
P4
dragon and the
controlling PC could have theoretically any distance between each others, as long as both have
contact to the Internet. If the
P4
dragon
is accessed in terminal mode, the distance between
P4
dragon
and PC really does not matter. Just with timing critical access protocols like
hostmode and applications like FAX the response time of the Internet can be the limiting
factor. A hostmode connection between two
SCS
locations inside Germany, however, was no
problem.
