Chapter 1 Introduction
Introduction
Outdoor Bridge is designed for outdoor environment application , the TDMA Bridge work on 2.4GHz，
and is a high-performance outdoor-deployable wireless bridge that provides wireless connectivity among
multiple network location. It provides higher reliability and changeable channel bandwidth, for long
distance point to point connectivity of up to 60km.
Based on powerful TDM technology, it is the best way to ensure higher quality between multi-media
transitions, for example, video, voice and image as well. Also, it is a right solution for telecommunication.

How to Login the WEB-Based Interface
The TDMA Bridge provides you with user-friendly Web-based management tool.
Open IE and enter the default IP address (Default: 192.168.1.1) and Login as below：

Figure 5 Login Interface
Enter the username (Default: admin) and password (Default: password) and click “Login”
!!! Caution
IP address of your PC must be the same subnet of device
After login, you can check basic information of device, such as MAC address off device, Firmware
version, etc.
Figure 6 Device Information
Basic System Setup
Into Base Setup, you can do basic settings of device：

Figure 7 Basic Settings
Device Name
Specify the device name, which is composed of no more than 15 characters with (0-9), (A-Z), (a-z) or (-).
Due to support WINS, You can use “Device Name” instead of IP address to access device via WEB
interface. For instance, device named as DEVICE0000FF, you can enter “DEVICE0000FF” in the IE,
then click “ENTER” and WEB page; or use “ping” command to check settings is active or not, such as
ping DEVEICE0000FF.
Ethernet Data Rate
Specify the transmission rate of data, default is Automatic.
Automatic / T-base10Mbps / T-Base100Mbps
IP Address
If you select “Manual”, you have to specify a static IP address, subnet mask, or get IP address from
DHCP.
IP Subnet Mask
Use subnet mask to ensure two devices in the same network.
Default Gateway
Default gateway and DNS server for your local area network which connects to the LAN port.

Primary DNS Sever
First choice of domain name server
Secondary DNS Sever
Second choice of domain name server
Figure 8STP Setup
STP Setup:
The Spanning Tree Protocol allows redundent connections to be created between different LAN
segments for purposes of fault tolerance.
Spanning Tree Protocol (STP) : Default is enable
Bridge Priority : 0 ~ 65535, default is 32768
Hello Time : 1 ~10, default is 2 seconds
Max Age : 6 ~40, default is 20 seconds
Forward Delay : 2 ~30, default is 2 seconds
Wireless Node Aging : 15 ~600, default is 15 seconds

Chapter 4 Wireless Settings
Basic Wireless Settings
Configure basic settings as following:
Figure 9 parameters of wireless
Remote MAC Address:
To specify remote device MAC address. Two devices have to assign MAC address of each other. And
make sure the same parameters of Security, Radio for connection.
Cipher:
There are three modes for encryption of security, NONE, WEP and AES.
Cipher Phrase:
When cipher is WEP、AES, system will generate 128bit dynamic key of WEP or AES.
RF Bandwidth
Decide bandwidth of Radio Frequency. Including 5 / 10 / 20 / 40 MHz (5 / 10MHz Coming soon)
Channel / Frequency
To select suitable channel and frequency from pull down menu, such as 2,437MHz and auto channel.

TX Rate
Normally choice transmission rate as “Best”, system will adapt best rate for real environment.
Including 64QAM 3/4, 64QAM 2/3, 16QAM 3/4, 16QAM 1/2, QPSK 3/4, QPSK 1/2, BPSK 3/4, BPSK 1/2
TX Power
Transmission power, 1/2 of transmission power equals to 3dB. Including Full / Half / Quarter / Eighth /
Min
Half: -3 dB
Quarter: -6 dB
Eighth: -9 dB
Min: -12 dB
WLAN Status
In this page, it can show remote bridge RSSI for local bridge and local bridge RSSI for remote bridge.
We can decide the best direction of antenna from following steps:
1. We check the RSSI only in one side. (We call it local side.)
2. Fix remote side antenna, and adjust local side antenna. In local side, check the “RSSI” first, to find a
best RSSI and then fix the local antenna.
3. Adjust the Remote antenna, to find the Best Remote RSSI, and then fix the remote antenna.
4. If “RSSI” is changed, and worse than before, adjust local antenna again to get a best one and fix
local antenna.
5. If “Remote RSSI” is changed and worse, adjust remote antenna again.
6. Follow the same ways to get a better RSSI and Remote RSSI value. And Fix both side antennas.

Throughput
Throughput show graphs which continuously represents the current data traffic on the Wireless interface.
The chart scale and throughput dimension (Bps, Kbps, Mbps) changes dynamically according to the
throughput value. Throughput statistics is updated automatically.
Figure 11 Throughput
Statistics
Display wired and wireless statistics of packets including transmitted and received packets, Uncast,
Broadcast, Multicast and total Packets.

Chapter 5 Management
Change Password
Via “Change Password”，you can modify password for WEB management.
Figure 13 Password
You have to enter “Current Password” first (default is password), then can change new password,
maximum length of password is 63 bytes. Choice “Restore Default Password”, it will restore password as
default setting as “password”.
Remote Management
Figure 14 Remote Management

Remote Console
The TDMA Bridge supports CLI management, which could be accessed by Secure Shell
(SSH). It is recommended PuTTY be used to login. Download it
from http://www.putty.org/ for free. The minimum system requirement for using PuTTY is
Windows 95, 98, ME, NT, 2000, XP and Vista on Intel x86.
Follow the steps below to implement:
Once the program is downloaded, open up by double-clicking. Note that before using
PuTTY, be sure you are able to connect to the Outdoor Bridge.
Enter IP Address of TDMA Bridge (Default: 192.168.1.1), Port (22) and check SSH as
connection type;
Figure 15 PuTTY Configuration 1
From “Connection” in the left menu bar, click “SSH”; select “2” as “Preferred SSH
protocol version”; make “3DES” the top position in “Encryption cipher selection policy”;
Figure 16 PuTTY Configuration 2

Click “Open”, a window as below will popup:
Figure 17 SSH
Enter the user name and password (Default user name/ password: admin/password)
respectively, you will see “DEVICE123456>”, which is the name of TDMA Bridge;
Upgrade Firmware
Via WEB interface to upgrade firmware：
Figure 18 Upgrade Firmware
Open “Upgrade Firmware” page。
Click “browse” to select new “Firmware” .
Click “Upload” send Firmware to device.
After checked Firmware by system, it starts to upgrade firmware, and will back to Login page after
firmware upgrade successful, otherwise system will show you the reason why it failed.
!!! Caution
Do NOT cut the power off during upgrade, otherwise the system may crash!

Backup/Restore
It would be better to backup settings of device after it work fine, so that you can recover settings quickly
when something go wrong.
Figure 19 Backup/Restore
