  • Page 10: Functional Design

    Introduction ATTENTION 1. The AWK-4131 is NOT a portable mobile device and should be located at least 20 cm away from the human body. 2. The AWK-4131 is NOT designed for the general public. To deploy AWK-4131 units and establish a wireless network safely, a well-trained technician is required for installation.

    Small form factor pluggable transceiver with 1000BaseEZX, LC, 120 km, 0 to 60°C LED Indicators The LEDs on the front panel of AWK-4131 allow you to identity the status and wireless settings quickly. The LED for FAULT indicates the system failure and user-configured events. If the AWK-4131 cannot retrieve the IP address from a DHCP server, the FAULT LED will blink at an interval of one second.

    Reset Button The RESET button is located on the bottom panel of the AWK-4131. You can reboot the AWK-4131 or reset it to factory default settings by pressing the RESET button with a pointed object such as an unfolded paper clip.

  • Page 13: Communication Connections

    To ensure the IP68-rated connectivity, you must use a waterproof housing during any communication activities. An IP68-rated field installable plug, which is attached in the AWK-4131’s accessory pack, may be needed in this case. The installation procedure is shown below:...

    3. Test the plug to ensure the quality. RS-232 Connection The AWK-4131 has one RS-232 (8-pin RJ45) console port located on the bottom panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect the Moxa AWK-4131’s console port to your PC’s COM port. You may then use a console terminal program to access the AWK-4131 for console configuration.

  • Page 15: Getting Started

    Getting Started In this chapter we explain how to install Moxa’s AirWorks AWK-4131 for the first time, and quickly set up your wireless network and test whether the connection is operating properly. The Function Map discussed in the third section provides a convenient means of determining which functions you need to use.

  • Page 16: First-Time Installation And Configuration

    First-time Installation and Configuration Before installing the AWK-4131, make sure that all items in the Package Checklist are in the box. You will need access to a notebook computer or PC equipped with an Ethernet port. The AWK-4131 has a default IP address that must be used when connecting to the device for the first time.

  • Page 17: Communication Testing

    How to Test One AWK-4131 If you are only using one AWK-4131, you will need a second notebook computer equipped with a WLAN card. Configure the WLAN card to connect to the AWK-4131 (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-4131.

  • Page 18: How To Test Two Or More Awk-4131 Units

    If you have two or more AWK-4131 units, you will need a second notebook computer (Notebook B) equipped with an Ethernet port. Use the default settings for the first AWK-4131 connected to notebook A and change the second or third AWK-4131 connected to notebook B to Client mode, and then configure the notebooks and AWK-4131 units properly.

  • Page 29: Wlan Security Settings

    SSID-hidden APs for IEEE 802.11b/g/n channels. WLAN Security Settings The AWK-4131 provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA2. Several security modes are available in the AWK-4131 by selecting Security mode and WPA type: •...
  • Page 30 When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be specified as 64/128 bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The AWK-4131 provides 4 entities of WEP key settings that can be selected to use with Key index. The selected key setting specifies the key to be used as a send-key for encrypting traffic from the AP side to the wireless client side.
  • Page 31 Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA security mode of some wireless APs and clients as well. The AWK-4131 also supports AES algorithms in WPA and WPA2 for better compatibility.
  • Page 32 AWK-4131 Web Console Configuration WPA/WPA2-Enterprise (for AP/Master mode) By setting WPA type to Enterprise, you can use EAP (Extensible Authentication Protocol), a framework authentication protocol used by 802.1X to provide network authentication. In these Enterprise-level security modes, a back-end RADIUS (Remote Authentication Dial-In User Service) server is needed if IEEE 802.1X functionality is enabled in WPA /WPA2.
  • Page 33 AWK-4131 Web Console Configuration WPA/WPA2-Enterprise (for Client/Slave mode) When used as a client, the AWK-4131 can support three EAP methods (or EAP protocols): EAP-TLS, EAP-TTLS, and EAP-PEAP, corresponding to WPA/WPA-Enterprise settings on the AP side. Encryption method Setting Description Factory Default...
  • Page 34 Certificate reduction makes TTLS and PEAP much more popular than EAP-TLS. The AWK-4131 provides some non-cryptographic EAP methods, including PAP, CHAP, MS-CHAP, and MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However, they may be useful as inner authentication methods with TTLS and PEAP.

  • Page 35: Advanced Wireless Settings

    There are a few differences in the TTLS and PEAP inner authentication procedures. TTLS uses the encrypted channel to exchange attribute-value pairs (AVPs), while PEAP uses the encrypted channel to start a second EAP exchange inside of the tunnel. The AWK-4131 provides MS-CHAP-V2 merely as an EAP method for inner authentication.

    AWK-4131’s STP/RSTP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every AWK-4131 connected to your network. If AWK-4131 plays a Slave role, which is connected to a device (PLC, RTU, etc.) as opposed to network switch equipment, it is not necessary to enable STP/RSTP. The reason is that it will cause unnecessary negotiation.

    E-mail Server Settings You can set up to 4 e-mail addresses to receive alarm emails from the AWK-4131. The following parameters can be configured on the E-mail Server Settings page. In addition, a Send Test Mail button can be used to test whether the Mail server and e-mail addresses work well.

  • Page 52: Relay

    None Relay The AWK-4131 has one relay output, which consists of 2 terminal block contacts on the AWK-4131’s top panel. These relay contacts are used to indicate user-configured events and system failure. 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.

    The following figure shows how the AWK-4131 stores the setting changes into volatile and non-volatile memory. All data stored in volatile memory will disappear when the AWK-4131 is shutdown or rebooted unless they are y. Because the AWK-4131 starts up and initializes with the settings stored in flash memory, all new changes must be saved to flash memory before restarting the AWK-4131.

    Other Console Configurations This chapter explains how to access the AWK-4131 for the first time. In addition to HTTP access, there are four ways to access AWK-4131: serial console, Telnet console, SSH console, and HTTPS console. The serial console connection method, which requires using a short serial cable to connect the AWK-4131 to a PC’s COM port, can be used if you do not know the AWK-4131’s IP address.
