Device Description
The
Bluetooth
®
ETHERNET gateway 758-915 (“WEG” – Wireless ETHERNET
gateway) enables ETHERNET devices to be linked to a wireless
Bluetooth
®
network, in which the data received via the ETHERNET interface is transmitted
via
Bluetooth
®
. In the other direction, data received at the
Bluetooth
®
interface is
transmitted via the ETHERNET interface. As data transmission of ETHERNET
packets occurs with a transparent protocol on Layer 2 of the OSI reference model,
this provides for easy integration of all Ethernet-based fieldbuses, such as
MODBUS/TCP, ETHERNET/IP, PROFINET or PROFISAFE.
Together with a further
Bluetooth
®
PAN profile compliant device with Ethernet
capabilities, such as a further WEG or a
Bluetooth
®
access point (AP), the WEG
can also be used as a wireless substitute for ETHERNET cables. As a
Bluetooth
®
Class 1 device with additional, special functions implemented which enhance
coexistence, the WEG provides particularly robust, real-time-capable radio links
over long distances without any adverse impact on other radio networks, such as
WLAN (IEEE 802.11 b/g).

An innovative operator control concept enables easy initiation of automatic
configuration processes using a Mode membrane key on the device. This can be
used to configure a substitute cable link between two WEGs in only a few
seconds, without using additional aids or hardware / software.
In addition to operation using the Mode membrane key and the 7 LED status
indicators, access to other status information and advanced device functions of the
WEG is also possible via a Web-based management system (WBM).
The WEG supports the “Simple Network Management Protocol” (SNMP).
Besides the object IDs (OIDs) for the RFC1213, the device also provides access to
further device-specific parameters. A corresponding description file for the
“Management Information Base” (MIB) is available from WAGO Support.
