Introduction The AWK-3131A-M12-RCC Series consists of 3-in-1 industrial AP/bridge/client devices designed specifically for rail carriage-to-carriage communication and can provide up to 300 Mbps with IEEE 802.11n technology. The new operation mode in the AWK-3131A-M12-RCC, Auto Carriage Connection (ACC), enables automatic wireless connections between two adjacent train carriages.
AWK-3131A-M12-RCC Introduction Overview The AWK-3131A-M12-RCC is 802.11n compliant to deliver speed, range, and reliability to support even the most bandwidth-intensive applications. The 802.11n standard incorporates multiple technologies, including Spatial Multiplexing MIMO (Multi-In, Multi-Out), 20 and 40 MHz channels, and dual bands (2.4 GHz and 5 GHz) to generate enough speeds, while still being able to communicate with legacy 802.11a/b/g devices.
AWK-3131A-M12-RCC Introduction Functional Design LAN Port The AWK-3131A-M12-RCC comes standard with 1 M12 Gigabit port. The LAN LED will light up when the LAN cable is inserted. ATTENTION Do not use the PoE Injector. Instead, use an IEEE 802.3af or IEEE 802.3at compliant PSE (Power Sourcing Equipment) for the PoE (Power over Ethernet) device.
AWK-3131A-M12-RCC Introduction LED Indicators The LEDs on the front panel of the AWK-3131A-M12-RCC provide a quick and easy means of determining the current operational status and wireless settings. The FAULT LED indicates system failures and user-configured events. If the AWK-3131A-M12-RCC cannot retrieve the IP address from a DHCP server, the FAULT LED will blink at one second intervals.
AWK-3131A-M12-RCC Introduction Color State Description WLAN is in AP/Master mode Amber On WLAN is in Client/Slave/ACC Master/ACC Slave mode with connection established Amber/Blinking Traffic in AP/Client/Master/Slave/ACC mode. WLAN Amber WLAN is in Sniffer mode. WLAN is in Client/Slave/ACC Master/ACC Slave mode without a connection being established or WLAN is not working properly.
AWK-3131A-M12-RCC Introduction Relay (Digital Output) The AWK-3131A-M12-RCC has one relay output consisting of the 2 terminal block contacts on the top panel, as shown below. These relay contacts are used to forward system failures 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.
Getting Started This chapter explains how to install Moxa’s AirWorks AWK-3131A-M12-RCC for the first time, and quickly set up your wireless network and test whether the connection is running well. The Function Map discussed in the third section provides a convenient means of determining which functions you need to use.
AWK-3131A-M12-RCC Getting Started First-Time Installation and Configuration Before installing the AWK-3131A-M12-RCC, 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-3131A-M12-RCC has a default IP address that must be used when connecting to the device for the first time.

AWK-3131A-M12-RCC Web Console Configuration The AWK-3131A-M12-RCC 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. Because the inner and outer authentications can use distinct user names in TTLS and PEAP, you can use an anonymous user name for the outer authentication, with the true user name only shown through the encrypted channel.
Page 35
AWK-3131A-M12-RCC Web Console Configuration PEAP 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-3131A-M12-RCC provides MS-CHAP-V2 merely as an EAP method for inner authentication.

AWK-3131A-M12-RCC References Beacon A beacon is a packet broadcast by the AP to keep the network synchronized. A beacon includes the wireless LAN service area, the AP address, the Broadcast destination address, a time stamp, Delivery Traffic Indicator Maps (DTIM), and the Traffic Indicator Message (TIM). Beacon Interval indicates the frequency interval of AP. DTIM Delivery Traffic Indication Map (DTIM) is contained in beacon frames.
AWK-3131A-M12-RCC References Differences between RSTP and STP RSTP is similar to STP, but includes additional information in the BPDUs that allow each bridge to confirm that it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge. Adjacent bridges connected via point-to-point links will be able to enable a link without waiting to ensure that all other bridges in the network have had time to react to the change.
