may accommodate up to 4 remote MAC addresses.

4) Bridge Security

Please refer to “Bridge Security Setting” in the next section.

5) Wireless Mode

There are two modes provided: 54 Mbps (802.11a) and 108Mbps (802.11a

Turbo). The mode of 108 Mbps offers the double data rate than of 54 Mbps.

6) Channel

Select a radio channel according to the availability or system plan. It is

required for Bridges having the same radio frequency to communicate each

other.

NOTE: You must to select the appropriate “Channel” setting according

to where the radio located to not to violate the local RF regulation. For

example, the radio frequency from 5.745GHz to 5.825GHz is allowed only in

USA.



7) Data Rate

Available data rate range is dependent on the selection of Wireless Mode in 5

GHz Radio Basic Setting page. Rates of 6, 9, 12, 18, 24, 36, 48 and 54 Mbps

are supported for the wireless mode of 54 Mbps (802.11a). And, rates of 12, 18,

24, 36, 48, 72, and 108 Mbps are supported for the wireless mode of 108 Mbps

(802.11a Turbo). The mode of 108 Mbps offers the double data rate than of

54Mbps.

NOTE: In order to maximize the system performance, it is recommended

to follow the following suggestions.

� For Master Bridge, it is recommended to set data rate into “best” on Master

Bridge to communicate with Slave Bridges of different distance and signal

strength.

� For Slave Bridge, it is recommended to check or predict the received signal

strength at the Slave Bridge, and pick a supported data rate according to the

following table.

NOTE: 3 to 5 dB additional margin is recommended to maintain a reliable

link.

8) RTS/CTS 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

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 1 km to 28 km for normal mode and

1 km to 14 km in turbo mode.

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 (e.g. 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.

Warnings 1: It is required to setup the same options of Super Bridge

Mode between Bridges to communicate.

Warnings 2: It very depends on the deployed site environment to decide

whether turning on Bursting and 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) Antenna Gain (for DFS-regulated country only)



Input the 5 GHz antenna gain for DFS (Dynamic Frequency Selection)

parameters setting.

14) Suppressed Channel List (for DFS-regulated country only)

Click to edit the 5 GHz channels that you want to suppress the channel(s) to be

selected by the system when radar attacked. Please refer to “Bridge

Suppressed Channel List” in next section.

15) Max EIRP

Displays the maximum EIRP (Effective Isotropic Radiated Power) defined by

the selected country.

16) Antenna Gain

Input the antenna gain of 5GHz antenna you used. If you purchase the internal

antenna model, the antenna is 17dBi. The valid range of this field is between 0

to 29 dBi.

17) Cable Loss

Input the cable loss of 5GHz antenna cable. The valid range of this field is

between 0 to 9 dBm.

18) Transmitter Output Power

Input the 5GHz transmit power you desire. The valid range of this field is

between 3 to 20 dBm. However, system will reject the input if the power you

input is greater than

(Max EIRP) - (Antenna Gain) + (Cable Loss).

The encryption mechanism can be “WEP”, “AES” or “TKIP”.

4) Key Length

For "WEP" encryption, the key length can be “10 HEX / 5 ASCII”, “26 HEX /

13 ASCII” or “32 HEX / 16 ASCII”.

For "AES" encryption, the key length is “32 HEX / 16 ASCII”.

For "TKIP" encryption, the key length is “32 HEX / 16 ASCII”.

5) Encryption Key

Input the encryption key according to Entry Method and Key Length. When

Entry Method = [Hexadecimal], the key must be hexadecimal (0-9, A-F). And,

when Entry Method = [ASCII Text], the key input can be any character.



When Share Key is set, all Master-Slave links use this key to encrypt except the

link(s) specified with Unique Key.

In some special applications, you may need to assign different key for each

Master-Slave link instead of the same key for all links. It can be done by

setting up Unique Key per MAC address of Slave Bridge.

For example:

When Entry Method = [Hexadecimal] & Key Length = [64 bit (10 hex digits / 5

ASCII keys)], the key can be “F1E2D3C4B5”.

When Entry Method = [ASCII Text] & Key Length = [64 bit (10 hex digits / 5

ASCII keys)], the key can be “aB#cd”.



6.2 Share Key / Unique Key

6.2.1 Setup Share Key

When Share Key is set, all Master-Slave links use this key to encrypt except the link(s)

specified with Unique Key. To setup Share Key, please input “Entry Method” and

“Encryption Type” first.

6.2.2 Setup Unique Key

In some special applications, you may need to assign different key for each

Master-Slave link instead of the same key for all links. It can be done by setting up Unique

Key per MAC address of Slave Bridge.

NOTE: It is required to have the same security setting between linked Bridges to

communicate.

6.3 Slave Bridge Security Setting

Slave Bridge security setting may apply on bridges of “Point-to-Point” network as well as

“Point-to-Multipoint” network.



For a “Point-to-Point” bridging network, 2 bridges to communicate each other need to use the

same key of same encryption type.

For a “Point-to-Multipoint” bridging network, the key and encryption type have to be the

same with Unique Key setting assigned to this Slave Bridge. Or, if there is no corresponding

Unique Key being assigned on Master Bridge, then Slave Bridge should follow the Share Key

assigned on Master Bridge.

Appendix B: FAQ / Troubleshooting

I can only have “5GHz 54Mbps (802.11a)” option, I can’t find any option for “5GHz 108Mbps

(Turbo a.) If as product specified, how can I see it?

� In the “Management” page, please choose your country as where you live. However, in

some radio regulation domain, Turbo Mode is NOT allowed; therefore, only “5GHz

54Mbps(802.11a)” option is shown.

There is a distance option for “Bridge Mode”, how can I benefit from it?

� You’d better to set the proper distance as in real field installation. This is because that

Bridge will “try” to wait the ack from the associated Bridge – the longer the distance; the

longer the Bridge would wait the response. If too short setting distance is set than the

real distance, the Bridge may recognize that his associated one is not there.

The Bridge does not respond ping request

� To make sure the correct IP address of bridge.

� To check whether the IP address of bridge and PC is in the same subnet.

� To check whether there is another device use the same IP address.

� Perform “arp -d” before each ping request on PC.

� To make sure there is no network loop.



The bridges could not associate appropriately with each other:

� To make sure the cables is connected properly.

� To check the PoE adapter’s green light is on or not.

� To check the both Frequency settings are on the same channel or not.

� To check the data rate is matched with one and another through the statistic RSSI display

or the advance setting inside the Frequency setting.

� To make sure wireless MAC address of remote bridge is correctly input.

� To make sure you use the same encryption key on the both sides or during the bridge link.

� To make sure you use the same options of “SuperBridge” on the associated bridges.

� To check the Antenna is aligned appropriately before the Bridge’s association.

� To check whether RSSI is within healthy range.

If you experience the poor performance (high package loss rate) during the bridge link, it is

better for to check the following items:

� To check the range is still inside the Antenna range limitation or not.

� To make sure the Antenna is aligned properly again.

� To make sure if there is no any obstruction in the middle of Line-of-Sign (LOS).

� To be sure there is no radio transmitter too close to the bridge s’ Antennas and relocated

the Antennas if you have some around.

� To check if you use too close frequency channels to cause the poor link and to set another

channel.

� To ping one and another IP address to make sure it will reply or not.



If all recovery measures fail, the bridge still couldn’t function properly and take this action

as what we recommend:

� Do not open the bridge box by yourself.

� Contact the technical support experts for the troubleshooting.

� If you do open the bridge, you will lose the manufacture warranty.

What’s the difference between “Master Bridge” mode and “Slave Bridge” mode:

� In “Point to Point” mode: There are only 2 bridges associate to each other, so set each

Bridge to “Slave Bridge” can fulfill the need.

� In “Point to Multi-Point” mode: A bridge (which is configured as “Master Bridge”) can

get associated with multiple bridges (each of them is configured as “Slave Bridge”). A

“Master” bridge can connect up to 4 “Slave” bridges.

� As default, it is set as “Slave Bridge”, unless specify especially.

Why the RF signal is not good:

� Check the antenna frequency is corresponding to the Bridge.

� Check if there are obstructions in the installed environment.

� Or there are other RF signals around which result in the interference.
