Note 
Terminating resistor 

Each WLAN interface has three antenna connectors. Connectors that are not used must 

have a terminating resistor fitted, see Accessories (Page 22). 
The antennas R1A1 and R2A1 must always be connected as soon as the associated 

WLAN Interface is turned on. if no antenna is connected, the relevant interface must also 

be disabled for RX and TX. Otherwise, there may be transmission disruptions. 
You will find information on the configuration of the antennas in the following
