8) Distance (Km)
Enter the distance according to the longest link between the Master and Slaves in the network. The value
needs to be greater than or equal to the real distance. The range is from 1Km to 35Km.
9) RTS Threshold
In order to prevent the transmission collision in a hidden nodes environment, Bridge may send a RTS
(Request To Send) before transmitting the data frame from remote Bridge. You may define a threshold for
those frame size greater than the threshold need to activate RTS mechanism. The valid range is from 256
to 2347. Set low value to this threshold may avoid collision, but the RTS frame would consume bandwidth.
Note: In Point to Multi-Point application, the transmission collision may be caused by hidden
nodes affection in particular environment or network configuration. Setting smaller number of RTS
threshold could alleviate the hidden nodes problem.
