These instructions explain the Ethernet / Wireless bridge installation for SEFRAM 8440 –DAS1400 –DAS 600 recorders. In our
example, this bridge will be used in a simple point-to-point network for the implementation of a recorder in the company wireless
network.
Operating principle
Principal diagram
This type of Ethernet / Wireless bridge is used to connect the recorder to a company wireless network. Thus, the recorder can
be monitored by remote applications, particularly with the software SEFRAM Pilot.
Recorder setting
To go to the network parameters of the recorder, press « Set-up » / « Ethernet » line / « Option » / « modif » keys. In this
menu, it is necessary to configure the different components according to company network parameters (contact your network
manager).

Once the presets performed, Ethernet / Wireless bridge has to be setup before being connected to the recorder. For this,
connect it on the company network and launch a communication via your web navigator by inputting its IP address in the URL bar.
The bridge control window is displayed. This window depends on the bridge used but the setting of each one follows the principle
below.
1) Press on the menu corresponding to bridge settings
2) In the setting window, tick « Wireless Point To Point bridging » settings and, if necessary « Enable wireless Client
Association » option (enables the wireless customers such as laptops, to use access points to be connected to the network). Then,
fill in the Mac address field of the wireless access point to which you have to be connected (written down on its case).
3) Confirm the changes performed by pressing « Apply ».
4) Once the configuration is complete, restart the bridge.
Below, the setting window corresponding to the use of a bridge.

Do not forget to perform the same operation to set the second access point (here wireless access point of the
company). This access point can be another bridge or standard wireless point. In any case, settings are similar to
the detailed one (network type, Mac address of the bridge, confirm and restart).

Recorder connection to network
The bridge and the access point configured, you have to connect the recorder to the bridge and start the communication
process with the network. By using SEFRAM Pilot, it is now possible to remotely monitor the recorder through a wireless connection.
Note
During the configuration with the network, it is important to properly set the fields concerning the security of your communications.
The wireless fidelity (IEEE 802.11i) offers options for the security as well as the access control in the support (MAC address) and
data encryption (WPA2 and its derived). To enter these menus, you have to be connected to the bridge (and to the wirele ss access
point) and access the specific tabs for the security. Below, the window corresponding to the settings of our bridge.

It can be interesting to test the communication between the unit and the network regardless to other settings.
From a PC, go to « start » / « execute » / « cmd » and confirm.
A command prompt is opened, input « ping <recorder IP address > » (here, 135.150.011.044) to check that the
recorder is reachable. If the connection is not established, check the network settings of the different units.
