Safety Precautions
This chapter describes safety precautions and product information
you have to know and check before installing DAP-3760.
1. Please seek assistance from a professional installer who is well
trained in the RF installation and knowledgeable in the local
regulations.
2. The DAP-3760 is distributed through distributor and system installer
with professional technicians and will not be sold directly through
retail store.
To keep you safe and install the hardware properly, please read and
follow these safety precautions.
1. If you are installing an DAP-3760 for the rst time, for your safety as
well as others’, please seek assistance from a professional installer
who has received safety training on the hazards involved.
2. Keep safety as well as performance in mind when selecting your
installation site, especially where there are electric power and
phone lines.
3. When installing your antenna, note the following:
• Do not use a metal ladder;
• Do not work on a wet or windy day;
• Wear shoes with rubber soles and heels, rubber gloves, long
sleeved shirt or jacket.
4. When the system is operational, avoid standing directly in front
of the antenna. Strong RF elds are present when the transmitter
is on.

Connect Up
Before installing the Ethernet cable with a waterproof RJ-45 connector,
it is recommended that the Cat-5 RJ-45 coaxial cable be used for the
bridge to power injector connections.
1. To connect to the hole labeled PoE+Data, open the black cover in
advance by using a coin or a slotted screwdriver and then screw
in the body of the gland and tighten.
2. Slide the sealing nut to the RJ-45 cable from its middle breach and
then insert the sealing into the cable.
3. Insert the RJ-45 connector and make sure that the locking tab
snaps home.
4. Screw the sealing on the gland and tighten.
Ground the wire
Power On

Connect Up Ground the wire
Power On
The DAP-3760 is shipped with a grounding wire. The unit must be
properly grounded to protect against power surges. The grounding
point can be found on the bottom of the unit. It is supplied with an
appropriate grounding lug for attachment to the ODU.
To power up the DAP-3760, follow the steps bellow:
1. Plug a user-supplied Cat-5 Ethernet cable from your wired LAN (or
a computer) into the power injector RJ-45 jack (DATA IN);
2. Plug a user-supplied Cat-5 Ethernet cable from the DAP-3760 into
the power injector RJ-45 jack (P+DATA OUT);
3. Connect the power module to the power injector and plug the AC
cord into an AC power receptacle.
4. After being powered on, the device will send out the beep sound
lasting about 1.5 seconds, informing you that the DAP-3760
powered up! Wait for about 60 seconds the system will be initialized
and start working.

12D-Link DAP-3760
Warning:
Make sure PoE is correctly connected to the RJ-45 port on the•
DAP-3760 labeled PoE+Data. DO NOT connect to the port
labeled “Warning!! No POE”, otherwise the extender will be
severely damaged!

13 D-Link DAP-3760
If you are conguring the DAP-3760 locally (without connecting its
power injector to a wired LAN), connect a PC to the power injector’s
Ethernet port using a Category 5 Ethernet cable.
1. Assign a static IP address to your PC which is in the same network
segment with the DAP-3760.As the default IP address of this unit is
192.168.0.50, you may choose from 192.168.0.1 to 192.168.0.254,
except 192.168.0.50.
2. Test the link status between your PC and the DAP-3760. Start a
command prompt and execute a continuous ping command “ping
192.168.0.50 –t”. If ping to the wireless bridge is successful (as
shown below), open Internet browser and enter the bridge’s IP
address in the address led and press Enter.
Conguration
Connect the DAP-3760 to a Local Computer

14D-Link DAP-3760
Note:
Considering convenient conguration, it is recommended to • configure local and remote DAP-3760 respectively on two
computers.
TTL time may vary depending on the operating system.•

15 D-Link DAP-3760
The DAP-3760 supports Bridge (CSMA) and Bridge (TDMA) modes.
Normally. Here we will illustrate how to establish wireless bridge
connectivity with DAP-3760.
Enter the user name (admin) and password (Null) to login and•
make congurations.
Open “Basic Setup” in “System”, set the IP address of two DAP-• 3760s in the same network segment. e.g. local DAP-3760 as
192.168.0.50 and remote DAP-3760 as 192.168.0.51 and set the
IP Subnet Mask on both as 255.255.255.0
Note:
Due to browser’s security trusted sites, 192.168.0.50 might not able• to be opened. You may choose to continue to the website.
How to Establish Wireless Bridge Mode

16D-Link DAP-3760
Open “Radio” in “Wireless” and you will nd the default Mode • is Bridge (CSMA). Select to use the Bridge (CSMA) mode and
keep the Channel/Frequency and Bandwidth on both DAP-3760s
identical. Click “Apply” to save settings.
Warning:
Each IP address is unique within a LAN, otherwise IP collision•
may occur!

17 D-Link DAP-3760
Login the Web-based interface of local DAP-3760 and open “Bridge• Links Setup” in “Wireless”, input the WLAN MAC address of the
remote one to “Remote MAC Address 1” eld and click “Apply”;
Login the Web-based interface of remote DAP-3760, open “System• Information” in “System” and record the wireless MAC address of
it.

18D-Link DAP-3760
Use ping to check whether the link between the two DAP-3760 is• OK.
To get a better wireless connectivity, antenna alignment is strongly• recommended after both DAP-3760s are installed long distance apart.
Login the Web-based interface of the local DAP-3760 and open
“Bridge Links Setup” in “Wireless”. Hit “Align Antenna” button, an
antenna alignment tool will popup. Specify the Target RSSI and
click “Start” to begin the antenna alignment.
Warning:
The MAC address on the housing of DAP-3760 is the ETH•
MAC address; therefore it can not be used in Bridge Links.
The IP address of your PC should be in the same network•
segment to the one of bridges.

19 D-Link DAP-3760
Fix the local antenna and adjust the remote antenna elevation• and horizontal direction. During the adjustment, observe “Current
RSSI” in local DAP-3760. 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 xing the remote one. During the • adjustment, observe “Current RSSI” in the remote DAP-3760. Fix
the local antenna when it reaches your expectation.
Congratulations! You have primarily completed conguration on • DAP-3760 and they can be put into operation. For more advanced
congurations, please refer to the User manual.

Troubleshooting
This chapter provides troubleshooting procedures for basic problems
with the DAP-3760.
Q 1. What if my DAP-3760 fails to connect to the remote one?
• Ethernet Link: Check the availability of power to the bridge by
observing the LED status on the power injector.
- Green: The DAP-3760 is connecting to the backhaul
network.
- Off: The DAP-3760 disconnects from the wired network, check
whether the power cord and Ethernet cables to the network
and bridge are correctly connected.
• 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
options in each device are identical.
• Security Settings: Remote bridges attempting to authenticate
to your DAP-3760 must support the same security options
congured in your bridge, such as WEP and WPA (2)-PSK. If
your bridge fails to associate with others, check whether the
security settings are the same as your bridge settings.
• 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 “Conguration File”
from “Administrator Settings”
Q 3. What if I would like to download and restore my conguration
settings?
You may download by generating a conguration le or upload
the settings you have backed up previously in “Conguration
File” from “Administrator Settings”.
