Commissioning
5.1 Connecting locking units
To connect a locking unit with the online module, you have to perform the
following steps:
Manual pairing
To this purpose users must have access to the circuit board of the module to
operate the rotary switch and be able to press the button.
- Turn the rotary switch 10 to position 8.
- Set the locking unit, which you want to connect into the service mode by holding the service key in front of the locking unit.
- Within the duration of the service mode of the locking unit (15 seconds), briefly tap the 11 button. If the locking unit has been successfully coupled, it automatically leaves the service mode prematurely.
- If required, repeat the process by coupling further locking units in service mode by pressing the button.
Function rotary switch
| Position | Function |
|---|---|
| 0 | Basic position |
| 4 | Start service mode by pressing 11 briefly |
| 8 | Manual pairing: Connect the locking unit in service mode by pressing 11 |
briefly
Command-driven coupling
In this case coupling is performed via a command to the online module. This
provides the possibility to assign an address explicitly to the knob.
Furthermore this possibility is practical if the online module has been
mounted in places that are difficult to access (e.g. false ceiling). The
locking unit to be connected must be brought to programming mode by using the
service key card. Now the bus master must send the coupling command to the
online module which initiates a coupling.
5.2 Network identification and authentication
5.2.1 Port
The device uses port 1470. On most systems, this port can be used by normal
users without special rights.
5.2.2 MAC address
The online module always has four different directly consecutive MAC
addresses, one for each of the basic functions of the installed LAN module.
The addresses will always start with “E8”.
Example:
| 1 | E8:31:CD:CD:79:5C = MAC address Station (Wi-Fi) |
|---|---|
| 2 | E8:31:CD:CD:79:5D = MAC address Access Point (hotspot for configuration) |
| 3 | E8:31:CD:CD:79:5E = MAC address Bluetooth |
| 4 | E8:31:CD:CD:79:5F = MAC address LAN |
The MAC address of the online module can be determined in different ways:
Data matrix
- You can find the MAC address of the device coded in the data matrix installed on the LAN module 15.
- Scan the data matrix with a suitable mobile device (e.g. QR code reader of a smartphone). The last 12 digits of the determined text show the lowest of the MAC addresses (“MAC address Station (Wi-Fi)”).
Web interface
Two of the four MAC addresses (no.
1+2) can be viewed in the web interface:
- Start the web interface as described in the chapter “Configuration of the network interface”
- Tap on the button “Info”
- Scroll to the “Wi-Fi” section. This contains the MAC addresses:
- Station MAC: MAC address Station (Wi-Fi) next to
- Access point MAC: MAC address Access Point
5.2.3 Configuration of the network interface
To carry out own settings of the IP addresses, the CX8942 has a web
interface.
This can be addressed either via the LAN interface or the Wi-Fi interface of
the CX8942.
Starting via Wi-Fi
For the configuration, the CX8942 acts as a Wi-Fi Access Point (hotspot). You
require a mobile device with activated Wi-Fi for the configuration.
To start the Access Point, button 7 must be held down while the unit performs
a reset. After that all LAN-specific settings are reset to the factory state.
The pairing of the locking units remains
- Open the Wi-Fi device menu of your mobile device
- Keep the 13 button pressed
- Tap the reset button 14 or optionally reconnect the LAN cable.
- Continue to hold down the 13 button for at least one second until a Wi-Fi network with the SSID: “FSMLanConfig” is displayed in the Wi-Fi menu of your mobile device
- Release the 13 button
- Tap on the list entry “FSMLanConfig”
- Enter the password StartConfig
The web interface now starts automatically in a browser window.
Alternatively, it can also be opened via the IP address
192.168.4.1 in a web browser.
For security reasons, be sure to assign a new secure password in the web
interface.
Changing the password
- Tap the button “Configure network”.
- Select the “HTTP Basic Auth” under the item “Configure portal protection”.
- Select a secure password for the user “admin”.
Access to configuration tool via LAN connection
If the module is started by pressing the button in the Wi-Fi configuration
mode as described above, the LAN interface is not active. If the module is
started without pressing the button as described above, the website can be
reached via the address received via DHCP.
5.2.4 IP address in network
Assignment via DHCP
By default, the online module can automatically obtain an IP address via DHCP
when it is connected to a network. The automatically assigned address can
then, for example, be displayed with the test application of the UZReader
protocol “ClexSerUZ_ReaderTest”. In addition, the module should also appear in
the web interface of the router. The address can be viewed there as well.
Manual input of a static IP address
Select the option “Static IPv4” in the web interface under “Configure
network” in the “Ethernet settings”.
5.3 Configuring the online module
The configuration of the online mode normally takes place through the
connected third-party system and the corresponding function of the respective
protocols. Individual parameters of the online module can also be set directly
via a 868 MHz-connection or bus commands in the service mode.
- Carry out the settings (e.g. LAN/WLAN communication) by means of the associated software tool (details are available in the respective protocol description).
Operation
If an authorized transponder is held in front of the connected locking unit, a
radio connection is established with the online module and, depending on the
version, the authorization is requested via the corresponding protocol of the
third-party system.
If no radio connection can be established, for example in case of a power
failure or a wireless attack, the electronics of the locking unit drops back
into offline mode. In this mode the door can be opened with any transponder
with offline authorization.
In this case the electronics of the locking unit warns the user, however,
before opening with a distinctive visual and acoustic signaling.
When the locking unit is woken up, for example by a knob cylinder being turned
or a door handle or knob module being actuated, a wireless connection is also
established.
6.1 Reset
- Tap the reset button 13 or disconnect the device from the power supply (here LAN connection).
6.2 Resetting the configuration (factory reset)
Restarting configuration tools via Wi-Fi, as described in more detail in
chapter 5.2.3 “Configuration of the network interface”, resets the settings
made. To this purpose, the delete button 14 must be held down while the
unit performs a reset.
6.3 Firmware updates
The update tool “Clex FW Prog” is available to update the firmware of the
module. Contact your respective Integration partner.
The LAN interface has its own firmware, which can be updated via the web
interface (see section 5.2.3Fehler! Verweisquelle konnte nicht gefunden
werden.).
