NOTE

The above items come with the

customized versions.

Overview

The AWK-4121 outdoor wireless Access Point is an ideal solution for industrial applications that are hard to wire,

too expensive to wire, or use mobile equipment that connect to a TCP/IP network.

The AWK-4121 is rated for operation in the temperature range from -40 to 75°C, and its dust-tight and

weatherproof design is IP68-rated. An IP68 rating means the device is completely protected from dust and is

protected against the effects of immersion in water between 15cm and 1m in depth. This means you can set up

a WLAN or extend existing wired networks to outdoor locations and still maintain a reliable connection. The

AWK-4121 has two redundant DC power inputs for increased reliability, can be powered via PoE (discontinued

starting with HW Rev 2.0.0), and is easy to deploy.

STEP 1:

Remove the reset button cover.

STEP 2:

Using a pointed object, press and hold the reset

button.

Reset Button

The RESET button is located on the bottom panel of the AWK-4121. You can reboot the AWK-4121 or reset it

to factory default settings by pressing the RESET button with a pointed object such as an unfolded paper clip.

• System reboot: Hold the RESET button down for under 5 seconds and then release.

• Reset to factory default: Hold the RESET button down for over 5 seconds until the STATE LED starts

blinking green. Release the button to reset the AWK-4121.

Relay (Digital Output)

The AWK-4121 has one relay output, which consists of the 2 contacts for the 8-pin M12 connector on the

bottom panel, as shown below. These relay contacts forward system failure and user-configured events.

The two wires attached to the relay contacts form an open circuit when a user-configured event is triggered. If

a user-configured event does not occur, the relay circuit will remain closed. For safety reason, the relay circuit

is kept open when the AWK-4121 is not powered.

The AWK-4121’s relay status is summarized as follows:

First-time Installation and Configuration

Before installing the AWK-4121, make sure all items in the Package Checklist are in the box. In addition, you

will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-4121 has a default IP

address that you must use when connecting to the device for the first time.

Step 1: Select the power source.

The AWK-4121 can be powered by DC power input or PoE (discontinued starting with HW Rev 2.0.0). The

AWK-4121 will use whichever power source you choose.

Step 2: Connect the AWK-4121 to a notebook or PC.

Since the AWK-4121 supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or

crossover cable to connect the AWK-4121 to a computer. The LED indicator on the AWK-4121’s LAN port will

light up when a connection is established.

Step 3: Set up the computer’s IP address.

Choose an IP address on the same subnet as the AWK-4121. Since the AWK-4121’s default IP address is

192.168.127.253, and the subnet mask is 255.255.255.0, you should set the IP address of the computer to

192.168.127.xxx.

Step 4: Use the web-based manager to configure AWK-4121

Open your computer’s web browser and type http://192.168.127.253 in the address field to access the

homepage of the web-based Network Manager. Before the homepage opens, you will need to enter the user

name and password as shown in the following figure. For first-time configuration, enter the default user name

and password and then click on the Login button.

Communication Testing

After installing the AWK-4121 you can run a sample test to make sure that the AWK-4121 and the wireless

connection are functioning normally. Two testing methods are described below. Use the first method if you are

using only one AWK-4121 device, and use the second method if you are using two or more AWK-4121 units.

Testing Method for One AWK-4121

If you are only using one AWK-4121, you will need a second notebook computer equipped with a WLAN card.

Configure the WLAN card to connect to the AWK-4121 (NOTE: the default SSID is MOXA), and change the IP

address of the second notebook (notebook B) so that it is on the same subnet as the first notebook (notebook

A), which is connected to the AWK-4121.

After configuring the WLAN card, establish a wireless connection with the AWK-4121 and open a DOS window

on Notebook B. At the prompt, type

ping <IP address of notebook A>

and then press Enter (see the figure below). A “Reply from IP address …” response means the communication

was successful. A “Request timed out.” response means the communication failed. In this case, recheck the

configuration to make sure the connections are correct.

Testing Method for Two or More AWK-4121 Units

If you have two or more AWK-4121s, you will need a second notebook computer (notebook B) equipped with

an Ethernet port. Use the default settings for the first AWK-4121 connected to notebook A and change the

second or third AWK-4121 connected to notebook B to Client mode. Then, configure the notebooks and

AWK-4121s properly.

Wireless Settings

The essential settings for wireless networks are presented in this function group. Settings must be properly set

before establishing your wireless network. Familiarize yourself with the following terms before starting the

configuration process:

AP/Bridge: This mode provides both Access Point and Static LAN-to-LAN Bridging functionality. The static

LAN-to-LAN bridging function is supported by the Wireless Distribution System (WDS).

Client: This mode is for Dynamic LAN-to-LAN Bridging or Device-to-LAN scenarios. The Client automatically

establishes bridge links with other APs.

In either AP/Bridge or Client mode, the AWK-4121 forwards packets between its Ethernet interface (LAN) and

wireless interface (WLAN) to connect wired hosts on the Ethernet side with wireless host(s) on the wireless side.

There are two types of wireless links specified by the IEEE802.11 standard:

• STA-AP: This type of wireless link is established between an IEEE802.11 Station (STA) and an IEEE802.11

Access Point (AP). An STA is usually a client computer (PC or PDA) with a WLAN network interface card

(NIC). The Client mode is actually an STA.

• WDS: This type of wireless link is established between two IEEE802.11 APs. Wireless packets transmitted

along the WDS link comply with the IEEE802.11 WDS (Wireless Distribution System) format at the link layer.

Refer to the “Wireless Distribution System (WDS)” section in Chapter 5 for details. Keep in mind that

WPA/WPA2 CANNOT be supported in WDS.

To establish a static bridge link based on the WDS, the APs at both end of the WDS link must be configured

manually with each other’s MAC addresses. To establish a dynamic bridge link between an AP and a Client, both

devices must be configured with the same channel, and security settings (see “WLAN Security Settings” for

details). Moreover, the same SSID is also needed for clients that roam the APs in Bridge mode. The Client

automatically scans for any AP that is using the matched SSID and establishes a bridge link with the scanned

AP.

When the AWK-4121 is configured for Client mode, it can be used as an Ethernet-to-wireless (or LAN-to-WLAN)

network adapter. For example, a notebook computer equipped with an Ethernet adaptor but no wireless card

can be connected to this device with an Ethernet cable to provide wireless connectivity to another AP.

Basic Wireless Settings

The “WLAN Basic Setting Selection” panel is used to add and edit SSIDs. An SSID is a unique identifier that

wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a

network or sub-network can use the same SSIDs. You can configure your AWK to use up to 9 SSIDs, and

configure each SSID differently. All of the SSIDs are active at the same time; that is, client devices can use any

of the SSIDs to associate with the access point.

Click on Add SSID to create more SSIDs.
