2.0 Hardware Installation

2.1 Before You Begin

Please read this User Guide carefully before installing and using the equipment. The operating

distance range of your wireless connection can vary significantly depending on the physical position of

the wireless devices. Factors that can weaken signals by getting in the way of your network’s radio

waves are metal appliances or obstructions, and walls. Typical ranges vary base on the types of

materials and background RF (radio frequency) noise in your home or office.

For best performance of your wireless network, you are suggested to:

1). Avoid redundant obstacles and interference between the wireless devices.

2). Keep your AP away from appliances with a strong electric field or magnetic field, such as a

microwave oven or refrigerator.

3). Place the AP near the center of the area in which your computers operates

2.2 Basic Requirements

 Use only the power adapter provided with your AP

 The electrical outlet should be installed near the device and should be easily accessible

 Place your AP in a well ventilated place, far from direct sunlight, any heater, or heating vent

 Leave at least 2 inches (5cm) space around the device for heat dissipation

 Turn off your AP and unplug the power adapter in a lighting storm to avoid damage

 Use web browsers such as Microsoft Internet Explorer 5.0 or above

 Operating temperature: 0℃~40℃ (32℉~104℉)

 Operating Humidity: 10%~90%RH, Non-condensing

2.3 Connecting the Device

Figure 2-1 is an example of the typical application of DA2155-V1 in an infrastructure network. An

Infrastructure network contains an access point and a wireless or non-wireless router.

Figure 2-1 The Example of Infrastructure Network Incorporating the DA2155-V1

To establish a typical connection of the AP, please take the following steps:

1. Connect the Cable or DSL modem to a Router.

2. Locate an optimum location for the AP. The best place is usually near the center of the area in

which your PC(s) will wirelessly connect.

3. Adjust the direction of the antenna. Normally, upright is a good direction.

4. Connect the Router to the DA2155-V1 Access Point and power on the AP.

5. Then you can connect a desktop PC or laptop to your network. (Make sure your computer or

laptop is equipped with a Wireless Adapter.)



Note: If you are not so clear about how to connect your devices to the network, please

refer to Appendix A Application Example.

3.0 Quick Installation Guide

This chapter will guide you to configure your PC to communicate with the AP and to configure and

manage the DA2155-V1 easily with a web-based utility.

3.1 Configure the PC

This chapter will guide you to configure your PC to communicate with the AP. The wireless adapter-

equipped computer in your network must be in the same IP Address range as the AP. Manually

configure the IP address as 192.168.40.* (* is any integer between 1 to 250), and the Subnet mask

as 255.255.255.0 for your PC by following the instructions below.

Connect the local PC to the LAN port on the AP and configure the IP address manually for your PC.

1. Click Start (in the lower left corner of the screen), right-click My Network Connections and

choose Properties.

Figure 3-1

2. On the My Network Connections window shown as Figure 3-2 below, right-click LAN (Local

Area Connection) and choose Properties.

4. Configure the IP address manually.

1) Select Use the following IP address.

2) Enter 192.168.40.* (* is any integer between 1 to 250) into the IP address field,

255.255.255.0 into the Subnet mask filed.

3) Click OK to keep your settings.

Figure 3-4

5. Verify the network connection between your PC and the AP via the Ping command. The following

example is in Windows XP Operating System.

1) Click Start > Run tab. Enter cmd in the filed and click OK.

2) Type ping 192.168.40.252 on the screen that displays and then press Enter.

If the result displayed is similar to that shown in Figure 3-5 below, the connection between

your PC and the AP has been successfully established.

If the result displayed is similar to that shown in Figure 3-6 below, it means that your PC has

not connected to the AP.

Figure 3-6

Please check following these steps:

a) Check to see if your PC and the AP are right connected. The LED of LAN port which

you link to on the device and the LED on your PC’s adapter should be lit up.

b) Make sure the TCP/IP for your PC is configured correctly. If the AP’s IP address is

192.168.40.252, your PC’s IP address must be within the range of 192.168.40.1 ~

192.168.40.250.

3.2 Quick Setup

With a web-based utility, it is easy to configure and manage the DA2155-V1. The web-based utility

can be used on any Windows, Macintosh or UNIX OS with a web browser, such as Microsoft Internet

Explorer, Mozilla Firefox or Apple Safari.

1. To access the configuration utility, open a web-browser and type in the default address

http://192.168.4 0.252 in the address field of the browser.
