Chapter 1 Introduction
The DAP-3860 is a high-performance outdoor-deployable wireless bridge that provides wireless
connectivity among multiple network locations. The DAP-3860 has a built-in 23dBi planar antenna that can
deliver up to a 40Km connection. An external antenna may also be used to improve signal quality and
improve distance. The DAP-3860 allows for link aggregation by combining multiple links into one link with
greater transmission rate.
The DAP-3860 supports bridge mode,it allows for local area network (LANs) in different locations (buildings)
to be easily interconnected. The DAP-3860 delivers âlast mileâ broadband connectivity through its PTP and
The DAP-3860 allows to be operated on PTP mode in one card and on bridge in another. And with an
external omni antenna for bridge side may provide users with flexibility in various local coverage
With high throughput and long-distance transmission, the DAP-3860 is an ideal backhaul solution for
Carriers, Service Providers and Enterprises!

If you select âStatic(Manual)â, you have to specify a static IP address, subnet mask, default gateway
and DNS server for your local area network which connects to the LAN port of DAP-3860. Make
sure the specified IP address is unique on your network in order to prevent IP conflict. Dynamic(DHCP)
Enable âDynamicâ to allow the DHCP server within your local area network to assign an IP address
automatically. Spanning Tree Protocol (STP)
Chapter 3 Basic Settings 29
Spanning Tree Protocol is a link management protocol for RCP bridges which provides path
redundancy while preventing loops in a network. STP allows only one active path at a time between
the RCP bridges but establish the redundant link as a backup if the initial link fails. STP Forward Delay
STP Forward Delay is the time spent in detecting and learning network tree topology state before
entering the forward state. Default time value is 1 sec. Select Normal if you would like to modify the
parameter (4-30 seconds).
Link Aggregation combines two physical network links into a single logical link for increased
bandwidth. Besides, it provides load balancing.
Basic Wireless Settings
Open âRadioâ in âWirelessâ as below and select âWLAN 0â or âWLAN 1â to make basic wireless
configuration on radio card 1 and 2.

In a point to point environment where there are only two radios, Peer to Peer is recommended as it
works more efficiently.
Chapter 3 Basic Settings 30
Bridge (CSMA): The DAP-3860 connects to another wireless device within the same networking
program using CSMA protocol. CSMA ensures that only one node is transmitting on the network at any
one time. Under this mode, both PTP and PTMP are available. It is highly recommended to use this
mode when the distance between two nodes is less than 20km. Bridge (TDMA): The DAP-3860 connects to another wireless device within the same networking
program using TDMA protocol. TDMA divides each cellular channel into multiple time slots to increase
the amount of data that can be carried; hence increase the throughput. Under this mode, only PTP is
available and is suggested to use when the distance between the two DAP-3860s is greater than
20km. Wireless Band
The DAP-3860 can only communicate with wireless devices of 802.11a. Channel/Frequency
Channel varies much as the available band differs from country to country. Select a proper operating
channel in the drop-down list according to your situation. Data Rate
Usually âBestâ is preferred. Under this rate, the DAP-3860 will automatically select the highest
available rate to transmit. In some cases, however, like where there is no great demand for speed, you
can have a relatively-low data rate for compromise of a long distance. Band Width
Four levels are available: 20MHz and 40MHz. Among them, 40MHz can enhance the data rate more
effectively, but will take more bandwidth, thus cause possible interference. WMM
WMM (Wi-Fi Multimedia) is a subset of 802.11e. It allows wireless communication to define a priority
limit on the basis of data type, thus those time-sensitive data, like video/audio data, may own a higher
priority than common one. To enable WMM, the wireless client should support it. Super Mode
Super mode is an effective way to enhance performance. It can boost the transmission data rate up to
108Mbps. To enable Super Mode, the remote DAP-3860 should enable the function as well.

The DAP-3860 sends RTS (Request to Send) frames to certain receiving station and negotiates the
sending of a data frame. After receiving an RTS, that STA responds with a CTS (Clear to Send) frame
to acknowledge the right to start transmission. The setting range is 0-2346 in byte.
Specify the maximum size in byte for a packet before data is fragmented into multiple packets.
Setting it too low may result in poor network performance. Leave it at its default of 2346 is
Distance in Meters
To decrease the chances of data retransmission at long distance, DAP-3860 can auto adjust proper
ACK timeout value by specifying distance of the two nodes. Default distance is 10km. This will be
only usefully in CSMA mode.

Under Bridge (CSMA) mode, Antenna Alignment Tool is available. This function helps to point in the
approximate direction of the remote DAP-3860 antenna and assist user easily align the local antenna to
reach maximum signal strength.

To use Antenna Alignment Tool, follow the steps bellow:
âBridge Links Setupâ and select âWLAN 0â or âWLAN 1â. By clicking âAlign Antennaâ button,
âAntenna Alignment Toolâ window will popup.
Set the target RSSI (e.g. -70dBm) and click âStartâ button.
Wait about 5 seconds, the antenna alignment starts and performs alignment every one second.
Fix the local antenna and adjust the remote antenna elevation and horizontal direction. During the
adjustment, observe âCurrent RSSIâ in local DAP-3860. The value will refresh every 1 second. Fix
the remote antenna when it reaches your expectation. Usually, RSSI between -60 and -70dBm
indicates rather good signal strength.
Adjust the local antenna after fixing the remote one. During the adjustment, observe âCurrent RSSIâ
in the remote DAP-3860. Fix the local antenna when it reaches your expectation.
When the antenna alignment tool starts, the DAP-3860 will issue beep sound to indicate current
RSSI. Once the tool is closed the DAP-3860 will stop beeping. Frequency of beep indicate the

Chapter 6 Troubleshooting
This chapter provides troubleshooting procedures for basic problems with the DAP-3860. For warranty
assistance, contact your service provider or distributor for the process. Q 1. What if my DAP-3860 fails to connect to the remote one?
â¢ Ethernet Link: Check the availability of power to the bridge by observing the LED status on the
power injector or on top of the RJ-45 Jack of the unit.
- Green: The DAP-3860 is connecting to the backhaul network.
- Off: The DAP-3860 disconnects from the wired network, check whether the power cord and
Ethernet cables to the network and bridge are correctly connected.
â¢ Basic Configurations: Mismatched basic settings among bridges are the most common cause
of connectivity fail. If the bridge does not associate with a remote bridge, check whether in each
device are identical.
â¢ Security Settings: Remote bridges attempting to authenticate to your DAP-3860 must support
the same security options configured in your bridge, such as WEP and AES. If your bridge fails to
associate with others, check whether the security settings are the same as your bridge settings.
â¢ Antenna Alignment: If the methods above are all checked to be correct, you can observe and
verify antenna alignment with RSSI value. Q 2. What if I would like to reset the unit to default settings?
You may restore factory default settings in âConfiguration Fileâ from âAdministrator Settingsâ Q 3. What if I would like to download and restore my configuration settings?

Please check the followings:
â¢ Check whether the power supply is OK; Try to power on the unit again.
â¢ Check whether the IP address of PC is correct (in the same network segment as the unit);
â¢ Login the unit via other browser such as Firefox.
â¢ Hard reset the unit. Q 5. What if the signal quality is poor or not so good?
â¢ Check whether there is obstacle between units. Obstacle may lead to poor signal.
â¢ Check the antenna height. Place the unit in a high position can help to get a better
communication in long distance transmission.
â¢ Check the polarization direction of antenna. Keep the polarization direction of antennas on two
associating units the same; if not (one is horizontal, another is vertical), the signal quality may
â¢ Check the antenna angle. Align the antenna to the remote one if using directional antenna. Big
angle shift may lead to poor signal.
â¢ Check the feeder length. Too long feeder may increase the signal loss and affect the unit
