Instructions for use PRE030 Ethernet/wifi
PRE 10/20/30 Converter
PRE10/20/30 serves to connect an Elektrobock device (central PocketHome unit, PT41 thermostat,
etc.) to the Ethernet network. Thus the device connected can be controlled from any computer in the
LAN network; or from any place in the world by means of the internet.

Signalling, controls and connectors
1. green LED – power supply indication – LED is on if the device is connected to the mains.
2. red LED – communication with PC – LED is flashing during USB communication.
3. yellow LED – WiFi - LED is on if the WiFi interface is enabled.
4. yellow LED – Ethernet - LED is on if the Ethernet interface is enabled.
5. orange LED – network connection – LED is flashing if the device tries to connect to the network.
LED is on permanently if a WiFi network is selected and the device has successfully connected to
it or an Ethernet network is selected and communication has successfully been established
between the PC application and the target device (socket opened).
6. blue LED – communication – flashing during data transmission between the “PREXX” module
and the device connected to the module.
8. red LED – error – LED is on if connection to the WiFi or Ethernet network was unsuccessful.
9. Ethernet – RJ45 (Ethernet) connector – used for connection to the LAN or WAN network.
10. RS232 – RJ12 connector – used to connect the module to the target device (central unit…).
11. PWR – connector for the 5VDC power supply (use the AD05 jack power supply only).
12. mini USB connector – used for PC connection to set up the device.
RESET button – to be used if the device achieves an undefined state due to an error or if it stops
operating.

Every device connected to the network with the TCP/IP protocol (WiFi, Ethernet) has its own IP
address (two devices cannot have the same IP address in one network).
The IP address form is determined by settings of the pertinent network; in local networks, it is usually
192.168.X.X (not as a rule, however)
The IP address of the PREXX device must be chosen so that it belongs to the given subnetwork and
does not collide with another device in the subnetwork.
If the higher-level device (router) supports the DHCP service, the IP address can be assigned
automatically. This will prevent assignment of a different IP address in the event of power failure and
restoration (reset).
The TCP/IP protocol uses IP addresses to differentiate the individual devices, and the so-called ports
to differentiate services. The application-device communication is executed via a single selected port.
The port number is selected within the range of 0 to 65535; it is recommended to use a port which is
not normally used for the most common services (http, ftp, etc.).
If you want to access the device from a computer located outside the local network, the higher-level
device (gateway, router) of the network must be set up. The so-called public IP address is used for
external access from the internet network. Ask your local internet provider about the possibility of
acquiring a public IP address. Although some providers do not offer public IP addresses, they at
least enable setting of a specific “through” port for the IP address common for several users
(wireless connection providers, typically). Therefore, the NAT/PAT technology enables access to a
specific device in the local network through a specific port from a single IP address.
In the recommended configuration, a specific fixed IP address is assigned on the PREXX device, a
port selected, and the access from the WAN network to this specific IP address and port is set up on
the router.

Setting
The setting is done by means of well-arranged software which you can find on the CD
enclosed. The software is intended for the operating systems Windows XP, Vista, 7 and 8. It is
necessary to have installed Microsoft libraries, NET Framework, version 3.5.1 or higher. Further,
device drivers must be installed (you can also find them on the CD enclosed). Start the application
installation by the setup.exe file. During installation, follow the on-screen instructions.
Connect the PREXX device to the 230V mains by means of the supply adapter. The green
LED indicating power supply must light up. Connect the device to a computer by means of the USB
cable supplied and to this network by means of a standard UTP cable. If the orange LED is
flashing after you connect the adapter, wait until it stops flashing (approx. 20 seconds); only then
start the application. The following window appears:
Window for setting PRE10 and PRE30 in the ETHERNET mode
Window for setting PRE20 and PRE30 in the WiFi mode
¨
The application now tries to communicate with the device, which is indicated on the lower
panel. After communication has been established, settings can be done. If the machine was
set in the past and you just want to modify its settings slightly (change the port number, for
example), use the “Load settings” button. Thus the set values are transferred from the
device to the application.

Choose the type of connection you want to use – wireless (WiFi) or wire (Ethernet).
Only one connection type can be used at a time, not both simultaneously.
Choose whether you want to use the DHCP server to assign the IP address, or
manually set the values: IP address, subnetwork mask, initial gateway and DNS server.
Choose the number of the port you want to use for communication.
If you have chosen the WiFi wireless network, click on the “Update network list” button.
The wireless part will be enabled and available networks located (this operation takes
approx. 30 seconds). Choose the network you want to connect to from the list. If the
network is secured, select the type of encoding used and enter the access password.
Then click on the “Connect” button. After 20–30 seconds, the device connects to the
wireless network (indicated by a screen message). If the attempt at connection has
been unsuccessful, check the network settings, security type and password.
By the “Save settings” button, enter all of the set parameters in the device.
Test the connection with the „Test“ button. Presently, information appears about the
connection state and current IP address.
Having done and tested the necessary settings, close the application and disconnect the USB cable.
Thus the device is ready for use. Any supported device (like the PocketHome central unit) can be
connected to the communication socket with the cable supplied. Next, enter the preset IP address
and port in the control application of the pertinent device. Perform further operation according to the
given device manual.
Warning!
If the “PREXX” appliance is connected to a computer by means of the USB cable, it is in the
so-called communication mode. In this mode, the appliance does not communicate with the
device connected (such as the central unit).
Device memory
The device is equipped with the EEPROM memory. In the event of a power failure, all settings
are preserved. When power has been restored, the devise is automatically connected to the
selected WiFi or Ethernet network.
Factory settings restoration
If, for some reason, factory settings of the device must be restored, connect the device to the
computer through USB, start the application, open the “Further information” window, and click on the
“Restore factory settings” button. All LEDs on the device light up for about 10 seconds. Neither WiFi,
not the Ethernet interface are enabled in the default state (both yellow LEDs are off).
