4 SFP SFP slot for 100 Mbit/s fibre module (optional)
5 Serial Serial interface RS232
6 Relay N/O Alarm relay
3.3.3 Antenna connectors
Note
The three antenna for devices bintec WI1040n have 2 Transmit and 3 Receive func-
tions in n operating mode MIMO 2T3R. WLAN 1 Ant. 1 and WLAN 1 Ant. send and re-
ceive, Ant. 3 only receives.
For devices bintec WI2040n only 2 antenna are used for each of the 2 wireless mod-
ules. These are both sending and receiving antenna. There is no third receiving an-
tenna; this is MIMO 2T2R operating mode.
However gross rates of 300 Mbps are possible. The receiving sensitivity decreases
slightly. Only 2 antenna connections are required to operate bridgelink with dual polar-
isation antenna.
Antenna should be Lambda/2 or a multiple of this. In bintec WIx040n the antenna are
37 mm apart.
2.4 GHz Lambda/2 corresponds to 6.15 cm; 5 GHz Lambda/2 corresponds to 2.72 cm.
Devices with 802.11n support can use up to 3 antenna per wireless module. The assign-
ment of the existing 4 antenna connectors is shown in the following graphic:

3.3.4 LEDs
The LEDs show the radio status, radio activity, Ethernet activity and LED states of your
device. The LED states are indicated by combinations of the LEDs.
During the heating phase the red Failure LED flashes. Once this temperature has been
reached, the device continues with the start-up process.
All LEDs are on during the start-up process. This means the monitor has been started and
