1. Introduction
Thank you for purchasing our RB-120 Wireless LAN Access Point. This manual will assist you with
the installation procedure.
The package you have received should contain the following items:
- User manual
- RB-120 Access Point
- Power adapter
- SNMP utility CD
Note: if anything is missing, please contact your vendor
A wireless LAN is normally used in a predefined environment. In such a network, Access Points are
mounted at assigned places, each covering its own area in which wireless nodes can operate. These
Access Points are connected to a wired network to communicate with each other and with servers and
clients on that network.
The RAYTALK RB-120 Access Point can be connected to a 10/100 Mbps Ethernet network through
a RJ45 (UTP) connector.

3. Hardware Installation
1. Mount the Access Point firmly to the wall or proper location that is determined during the site survey.
2. Make sure the antennas are in a vertical position (if not, rotate over 90 degrees).
3. Insert the power connector.
4. Attach the UTP Ethernet cable to the Access Point.
At the front of the Access Point you will see three LEDs.
If all goes well, the middle LED (power) and the lowermost LED(LINK) will fire and uppermost
LED(ACT) will flash whenever there is traffic on the respective networks which is at least ten times per
second for the wireless LAN because of so-called ‘beacons’.
You can reset the Access Point’s settings to factory defaults by pushing a paperclip in the little hole
next to the power connector.

4.2 Advanced Setting
Advanced have two settings: Wireless and MAC filtering.
Wireless setting contains the following setup functions:
Beacon Interval: The Beacon Interval value indicates the frequency interval of the beacon. Enter a
value between 20 and 1000. A beacon is a packet broadcast by the Router to synchronize the wireless
network. The default value is 100.
RTS Threshold: This value should remain at its default setting of 2346. Should you encounter
inconsistent data flow, only minor modifications are recommended. If a network packet is smaller than
the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends
Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data
frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to
acknowledge the right to begin transmission.
Fragmentation Threshold: This value specifies the maximum size for a packet before data is
fragmented into multiple packets. It should remain at its default setting of 2346. If you experience a
high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the
Fragmentation Threshold too low may result in poor network performance. Only minor modifications of
this value are recommended.
DTIM Interval: This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A
DTIM field is a countdown field informing clients of the next window for listening to broadcast and
multicast messages. When the Access Point has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval value.
Access Point Clients hear the beacons and awaken to receive the broadcast and multicast messages.
User’s Guide 10

Basic Rates: Select the Basic speed of transmission, there are “1-2”Mbps and “1 -2 -5.5 – 11”Mbps
you can chose.
Transmission Rates: The rate of data transmission should be set depending on the speed of your
wireless network. You can select from a range of transmission speeds, or you can select AUTO to
have the Router automatically use the fastest possible data rate and enable the Auto-Fallback feature.
Auto-Fallback will negotiate the best possible connection speed between the Router and a wireless
client. The default setting is AUTO.
Preamble Type: Select the head length of the packet.
Authentication Type:
Auto: Auto is the default authentication algorithm.It will change its authentication type automatically
to fulfill client’s requirement.
Open System: Open System authentication is not required to be successful while a client may
decline to authenticate with any particular other client.
Shared Key: Shared Key is only available if the WEP option is implemented. Shared Key
authentication supports authentication of clients as either a member of those who know a shared
secret key or a member of those who do not. IEEE 802.11 Shared Key authentication accomplishes
this without the need to transmit the secret key in clear. Requiring the use of the WEP privacy
mechanism.
Antenna Selection: Select the antenna.
SSID Broadcast: SSID broadcast control.

5.3 Managing Security
Maintaining security in a wireless LAN environment is somewhat different from a wired network,
because the radio waves do not stop at your office walls. Eavesdropping or unauthorized access from
outside and your building can be a serious threat.
If you wish to enable the Privacy Options function, please click the “Setup” “Wireless LAN”
“Privacy Options” and choose the encryption method. The encryption key should follow the
hexadecimal format. The characters are only included “0” to “9” and “a” to “f”.
