2. You can connect an external antenna directly to the device or connect it with a flexible
connecting cable.
Place the antenna plug or the flexible connecting cable on the antenna connector and
tighten the sleeve nut of the plug on the antenna connector (wrench SW19, torque 1.7 Nm).
3. An antenna must always be connected to R1 A1
configuration of antennas in the WBM / CLI.
4. Screw a terminating resistor onto the unused antenna connector.
Note
Terminating resistor
Any connections that are not in use must be fitted with a terminating resistor, see Accessories

An antenna must always be connected to the antenna connector as soon as the WLAN interface
is switched on. Otherwise, there may be transmission disruptions.
Note

When installing the SCALANCE WxM766-1 in a cabinet, you need to use detached antennas. Use
a suitable flexible connecting cable for a connection between SCALANCE WxM766-1 and a
detached antenna. You will find detailed information in the section Accessories (Page 20).
