Installation

Assembling the Access Point

1. Assemble the dish of the DAP-3712 by sliding the two halves together until they lock in place.
   

2. Connect the antenna and base through the hole in the center of the dish.
   

3. Thread a standard RJ-45 Ethernet cable through the cover for the PoE port on the underside of the DAP-3712. Insert the cable into the PoE port, then attach the cover to the device.

4. Connect the adjustment kit to the base of the DAP-3712 by pressing it in until it clicks and locks in place. Use the adjustment kit to position the antenna at the desired angle.
   

Preparation before Installation

Before installing the DAP-3712, check the distance between the two sides and ensure that they are within wireless signal range of each other. It may be helpful to use a Graphic Information System (GIS) program such as Google Earth to check for obstructions between the two sites. If there is an obstruction, it may help to install the DAP-3712 as high as possible to prevent the signal from being blocked.

Note: Ensure that both devices have the same model number and are running the same firmware version. The radiation pattern and wireless protocol of the DAP-3712 is designed for high-performance bridge connectivity. Using different models or models with mismatched firmware versions may cause problems, such as performance degradation or a reduction in coverage area.

Powering the Access Point

To power the DAP-3712, use a standard Ethernet cable to connect the PoE port on the DAP-3712 to a 48 V PoE injector.

Cable Requirements

Use a CAT 5 cable with an even sheath. The Ethernet ports on the DAP-3712 access point cannot accept a CAT 5 cable that has an uneven sheath; the RJ-45 connector on the cable will not fit properly into the receptacle on the access point.

Configuring the First DAP-3712 in Access Point Mode

1. Use an Ethernet cable to connect the LAN port on the DAP-3712 to the PoE Out port on the PoE injector. Using another cable, attach the PoE injector to your switch or management computer.
   

2. Ensure the computer is configured with the static IP address 192.168.0.2 and a subnet mask of 255.255.255.0.

3. Launch a web browser. Enter 192.168.0.50 in the address field of your browser.

4. Log in to the administration user interface.
   The default login information is:
   Username: admin
   Password: admin

5. Follow the Setup Wizard’s instructions to configure the device in Access PointMode. Refer to Figure 9: Using the Setup Wizard for details.
   
   

Configuring the Second DAP-3712 in Client Mode

1. Follow steps 1-4 of the instructions above to power on the device. Launch the Setup Wizard to configure the device in Client Mode.

2. T o avoid an IP address conflict, change the IPv4 address so that it is different from the first DAP-3712’s IP address (for instance, by changing it to 192.168.0.51, as in the following screenshot).
   

3. On step four of the Setup Wizard (Wireless), select Client from the dropdown list. Enter the same SSID and key that you entered when configuring the first device.

4. To confirm that wireless connectivity between the two devices is configured correctly, navigate to the Status page and check the information under Associated Stations (shown below).
   

Mounting the Device

Installation Recommendations

If you plan to install the DAP-3712 on a pole, orient the front of the access point toward the intended coverage area. The radio antenna transmits through the front of the access point but not through the reverse side (where the bracket is).

Be sure to install the device at a height that ensures that the alignment between the devices is visible and there is no obstruction in the middle.

Checking the Signal Strength

Before fixing the device in place, slowly pan the DAP-3712 from side to side and check the LED indicator to find the position where the signal is strongest.

Mounting on a Pole

1. Hold the DAP-3712 against the pole in the desired position.
   

2. Thread the metal mounting tie through the hole on the base of the DAP-3712 and and wrap it around the pole. Fasten the tie to secure the device against the pole.
   

Once completed, your network will resemble the following diagram.

RF Frequency Requirements

This device is for outdoor use only. High power radars are allocated as primary users of the 5150 – 5250 MHz and 5725 – 5850 MHz bands. These radar stations can cause interference with or damage the PoE adapter of this device. This is a fixed point-to-point device.
