nodes environment, Bridge may send a RTS (Request To Send) before
transmitting the data frame and expect to receive a CTS (Clear To Send) from
remote Bridge. You may define a threshold for those frame size greater than
the threshold need to activate RTS/CTS mechanism. The valid range is
between 256 and 2346. Set low value to this threshold may avoid collision, but
the RTS/CTS frame would consume bandwidth.
9) Distance Setup “Bridge Distance” according to the longest link distance
between the Master and Slaves in the network. The input needs to be
greater than or equal to the real distance. The range can be from 1KM to
28KM.
10) Super Bridge Mode Super Bridge Mode provides three mechanisms to improve the
bridge throughput.
‹ Compression: Frame is compressed by hardware before transmitting.
Note that the compression may save bandwidth but would consume frame
process time. In case the data is already compressed (eg. mpeg frame),
please do NOT turn on this function.
‹ Bursting: Turning on Bursting function enables multiple frames are
transmitted at SIFS intervals which may reduce transmission overhead.
But this may increase packet error rate on the other side.
‹ Fast Frame: Turning on Fast Frame function enables two Ethernet
frames bundled into a single wireless frame.
Warning 1: It is required to setup the same options of Super Bridge
Mode between Bridges to communicate.
Warning 2: It very depends on the deployed site environment to decide
whether turning on Bursting & Fast Frame function or not.
11) Auto Reboot With this function enabled, Bridge will reboot itself
automatically while there is no data received for 30 seconds. This function is
disabled by default.
12) Spanning Tree Protocol This function is to prevent the network loop and
disabled by default. It is suggested you enable this function when the
network configuration is complicated.
13) Click and “Reboot” the system after setting.
