Overview
The TAP-213 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 MIMO
(Multi-In, Multi-Out) Spatial Multiplexing, multiple channels (5, 10, 20 and 40 MHz), and dual bands (2.4 GHz
and 5 GHz) to achieve high speeds, while still being able to communicate with legacy 802.11a/b/g devices.
The TAP-213 is compliant with the EN 50155 standard that covers operating temperature range, power input
voltage, surge, ESD, and vibration. The TAP can be easily mounted on to a DIN rail or in distribution boxes. Its
wide operating temperature range, IP68-rated housing with LED indicators, and the DIN-rail mounting
capability make the TAP-213 a convenient yet reliable solution for all types of industrial wireless applications.

Functional Design
LAN Port
The standard model of the TAP-213 is provided with one M12 X code Gigabit port. The LAN LED will light up
when the LAN-1 cable is inserted.
LED Indicators
The LEDs on the front panel provide a quick and easy means of determining the current operational status and
wireless settings of the TAP-213.
The FAULT LED indicates system failures and user-configured events. If the TAP-213 cannot retrieve the IP
address from a DHCP server, the FAULT LED will blink at one-second intervals.
Do not use a PoE (Power over Ethernet) Injector for the PoE device(s). Instead, use an IEEE 802.3af or IEEE

ATTENTION
When the system fails to boot, the LEDs for STATE (Green), FAULT, and WLAN will all light up
simultaneously and blink at one-second intervals. This may be due to improper operation or uncontrollable
issues, such as an unexpected shutdown while updating the firmware. To recover the firmware, refer to the
“Firmware Recovery” section in Chapter 6.
The following table summarizes how to read the device’s wireless settings based on the LED displays. More
information is available in Chapter 3 in the “Basic Wireless Settings” section.

First-Time Installation and Configuration
Before installing the TAP-213, make sure that all items mentioned in the package checklist are in the box. You
will also need access to a notebook computer or PC equipped with an Ethernet port. The TAP-213 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 TAP-213 can be powered by a DC power input or PoE (Power over Ethernet).
• Step 2: Connect the TAP-213 to a notebook or PC.
Since the TAP-213 is provided with the MDI/MDI-X auto-sensing capability, you can use either a
straight-through cable or crossover cable to connect it to a computer. When the connection between the
TAP-213 and the computer is established, the LED indicator on the TAP-213’s LAN port lights up.
• Step 3: Set up the computer’s IP address.
Set an IP address for the computer so that it is on the same subnet as that of the TAP-213. Since the
TAP-213’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, set the IP
• Step 4: Use the web-based manager to configure the TAP-213
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 following
default user name and password and click on the Login button:
User Name: admin
Password:
root
address
of
the
computer
in
the
192.168.127.xxx
IP
range
and
subnet
mask
to
255.255.255.0.
After you select Maintenance Load Factory Default and click the Submit button, the TAP-213 will be
reset to factory default settings and the IP address will be reset to 192.168.127.253.
For security reasons, we strongly recommend changing the default password. To change the password, select
Maintenance Password and follow the instructions on the screen.

• Step 5: Select the operation mode for the TAP-213.
By default, the operation mode of the TAP-213 is set to AP. You can change this setting to Client mode at
Wireless Settings Basic Wireless Settings. Detailed information about configuring the TAP-213 is
available in Chapter 3.
• Step 6: Test the network connection.
In the following sections we describe two methods that you can use to test that a network connection has
been established.
Communication Testing
After installing the TAP-213 you can run a sample test to make sure the wireless connection on the TAP-213 is
functioning normally. Two testing methods are described below. Use the first method if you are using only one
TAP-213 device, and the second method if you are using two or more TAP-213 units.
How to Test One TAP-213
If you are only using one TAP-213, you will need one additional notebook computer equipped with a WLAN card.
Configure the WLAN card to connect to the TAP-213 (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 TAP-213.
After configuring the WLAN card, establish a wireless connection with the TAP-213 and open a DOS window on
Notebook B. At the prompt, type the following:
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.
After you click Submit to apply changes, the web page is refreshed and an (Updated) indicator is displayed
next to the page heading along with a blinking reminder to restart the device.
To activate the changes, click Restart and then click Save and Restart after you change the settings. The
TAP-213 will take about 30 seconds to complete the reboot process.

How to Test Two or More TAP-213 Units
If you have two or more TAP-213 units, you will need a second notebook computer (Notebook B) equipped with
an Ethernet port. Use the default settings for the first TAP-213 connected to notebook A and change the second
or third TAP-213 connected to notebook B to Client mode, and then configure the notebooks and TAP-213 units
properly.
After setting up the testing environment, open a DOS window on notebook B. At the prompt type:
ping <IP address of notebook A>
and then press Enter. A “Reply from IP address …” response means the communication was successful. A
“Request timed out” response means the communication failed. In the latter case, recheck the configuration to
make sure the connections are correct. Cecilia_Fernandes

Web Browser Configuration
The web interface provides a convenient way to modify the configuration of the TAP-213 and access its built-in
monitoring and network administration functions. The recommended web browser is Microsoft® Internet
Explorer 7.0 or 8.0 with JVM (Java Virtual Machine) installed.
To access the web interface of the TAP-213, do the following:
1.
Open a web browser (e.g., Internet Explorer), type in the default IP address of the TAP-213 in the address
field, and press Enter.
2.
In the login page that is displayed, enter the Username and Password (default Username = admin;
default Password = root) and click Login to continue.
You may need to wait a few moments for the main page to download to your computer. Note that the model
name and IP address of the TAP-213 are both shown in the title bar of the web page. You can identify the
web interfaces of multiple TAP-213 units using this information.
3.
Use the menu tree on the left side of the window to open the configuration pages for the TAP-213’s
functions.
To use the management and monitoring functions of the TAP-213 from a PC host connected to the same LAN
as the TAP-213, you must make sure that the PC host and the TAP-213 are on the same logical subnet.
Similarly, if the TAP-213 is configured for other VLAN settings, you must make sure your PC host is on the
management VLAN.
The default IP address of the TAP is 192.168.127.253.

Wireless Settings
The essential settings for wireless networks are presented in the wireless settings function group. You must
configure these settings correctly before you establish your wireless network. Familiarize yourself with the
following terms before starting the configuration process:
AP: In a wireless local area network (WLAN), an access point is a station that transmits and receives data.
Client: When the TAP-213 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.
Operation Mode
The TAP-213 supports five main operation modes—AP, Client, Master, Slave, and ACC—each of which plays a
distinct role on the wireless network.

Basic Wireless Settings
You can add new SSIDs or edit existing ones in the WLAN Basic Setting Selection panel. You can configure
up to 9 SSIDs for a TAP and configure each SSID differently.
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. All of the SSIDs that
you configure for an AP are active at the same time. That is, client devices can use any of the SSIDs to associate
with the AP.
To create an SSID for your TAP, click on Add SSID. To edit an existing SSID and assign different configuration
settings to it, click on the Edit button corresponding to the SSID. A configuration panel is displayed as follows:

WLAN Security Settings
The TAP-213 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 TAP-213 by selecting
Security mode and WPA type:
•
Open: No authentication, no data encryption.
•
WEP: Static WEP (Wired Equivalent Privacy) keys must be configured manually.
•
WPA/WPA2-Personal: Also known as WPA/WPA2-PSK. You will need to specify the Pre-Shared Key in the
Passphrase field, which will be used by the TKIP or AES engine as a master key to generate keys that
actually encrypt outgoing packets and decrypt incoming packets.

For security reasons, you should NOT set security mode to Open System, since authentication and data
encryption are NOT performed in Open System mode.
WEP
According to the IEEE802.11 standard, WEP can be used for authentication and data encryption to maintain
confidentiality. Shared (or Shared Key) authentication type is used if WEP authentication and data encryption
are both needed. Normally, Open (or Open System) authentication type is used when WEP data encryption is
run with authentication.
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 TAP-213 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. All 4 WEP keys are used
as receive-keys to decrypt traffic from the wireless client side to the AP side.
The WEP key can be presented in two Key types, HEX and ASCII. Each ASCII character has 8 bits, so a 40-bit
(or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13 characters. In hex, each
character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit key has 26 characters.

WPA/WPA2-Personal
WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption method.
WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i.
The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key is
regularly changed so that true session is secured.
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 TAP-213 also supports AES algorithms in WPA and WPA2 for
better compatibility.
Personal versions of WPA/WPA2, also known as WPA/WPA-PSK (Pre-Shared Key), provide a simple way of
encrypting a wireless connection for high confidentiality. A Passphrase is used as a basis for encryption
methods (or cipher types) in a WLAN connection. The passphrases should be complicated and as long as
possible. There must be at least 8 ASCII characters in the Passphrase, and it could go up to 63. For security
reasons, this passphrase should only be disclosed to users who need it, and it should be changed regularly.

The key renewal value dictates how often the wireless AP encryption keys should be changed. The security
level is generally higher if you set the key renewal value to a shorter number, which forces the encryption keys
to be changed more frequently. The default value is 3600 seconds (6 minutes). Longer time periods can be
considered if the line is not very busy.

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. The IEEE 802.1X protocol also offers the possibility of carrying out an
efficient connection authentication on a large-scale network. It is not necessary to exchange keys or
passphrases.

Before choosing the EAP protocol for your WPA/WPA2-Enterpise settings on the client end, please contact the
network administrator to make sure the system supports the protocol on the AP end. Detailed information on
these three popular EAP protocols is presented in the following sections.
EAP-TLS
TLS is the standards-based successor to Secure Socket Layer (SSL). It can establish a trusted communication
channel over a distrusted network. TLS provides mutual authentication through certificate exchange. EAP-TLS
is also secure to use. You are required to submit a digital certificate to the authentication server for validation,
but the authentication server must also supply a certificate.
You can use Basic Wireless Settings WLAN Certificate Settings to import your WLAN certificate and
enable EAP-TLS on the client end.

EAP-TTLS
It is usually much easier to re-use existing authentication systems, such as a Windows domain or Active
Directory, LDAP directory, or Kerberos realm, rather than creating a parallel authentication system. As a result,
TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication
methods.”
TTLS and PEAP work in a similar way. First, they establish a TLS tunnel (EAP-TLS for example), and validate
whether the network is trustworthy with digital certificates on the authentication server. This step establishes
a tunnel that protects the next step (or “inner” authentication), and consequently is sometimes referred to as
“outer” authentication. The TLS tunnel is then used to encrypt an older authentication protocol that
authenticates the user for the network.
As you can see, digital certificates are still needed for outer authentication in a simplified form. Only a small
number of certificates are required, which can be generated by a small certificate authority. Certificate
reduction makes TTLS and PEAP much more popular than EAP-TLS.
The TAP-213 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. Keep in mind that not all client software supports anonymous alteration. Confirm this with the network
administrator before you enable identity hiding in TTLS and PEAP.

exchange inside of the tunnel. The TAP-213 provides MS-CHAP-V2 merely as an EAP method for inner
authentication.

Advanced Settings
Several advanced functions are available to increase the functionality of your TAP-213 and wireless network
system. A VLAN is a collection of clients and hosts grouped together as if they were connected to the broadcast
domains in a layer 2 network. The DHCP server helps you deploy wireless clients efficiently. Packet filters
provide security mechanisms, such as firewalls, in different network layers. Moreover, the TAP-213 can support
STP/RSTP protocol to increase reliability across the entire network, and SNMP support can make network
management easier.
Using Virtual LAN
Setting up Virtual LANs (VLANs) on your TAP series increases the efficiency of your network by dividing the LAN
into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.
The Virtual LAN (VLAN) Concept
What is a VLAN?
A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that
communicate as if they were attached to the same broadcast domain, regardless of their physical location. A
VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if
they are not located on the same network switch. Network reconfiguration can be done through software
instead of physically relocating devices.
VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless
sub-networks via SSID and VLAN assignment. A Client can access the network by connecting to an AP
configured to support its assigned SSID/VLAN.
Benefits of VLANs
VLANs are used to conveniently, efficiently, and easily manage your network in the following ways:
•
Manage adds, moves, and changes from a single point of contact
•
Define and monitor groups
•
Reduce broadcast and multicast traffic to unnecessary destinations
•
Improve network performance and reduce latency
•
Increase security
•
Secure network restricts members to resources on their own VLAN
•
Clients roam without compromising security
VLAN Workgroups and Traffic Management
The AP assigns clients to a VLAN based on a Network Name (SSID). The AP can support up to 9 SSIDs per radio
interface, with a unique VLAN configurable per SSID.
The AP matches packets transmitted or received to a network name with the associated VLAN. Traffic received
by a VLAN is only sent on the wireless interface associated with that same VLAN. This eliminates unnecessary
traffic on the wireless LAN, conserving bandwidth and maximizing throughput.
In addition to enhancing wireless traffic management, the VLAN-capable AP supports easy assignment of
wireless users to workgroups. In a typical scenario, each user VLAN represents a department workgroup; for
example, one VLAN could be used for a marketing department and the other for a human resource department.
In this scenario, the AP would assign every packet it accepted to a VLAN. Each packet would then be identified
as marketing or human resource, depending on which wireless client received it. The AP would insert VLAN
headers or “tags” with identifiers into the packets transmitted on the wired backbone to a network switch.

Finally, the switch would be configured to route
packets from the marketing department to the
appropriate corporate resources such as printers
and servers. Packets from the human resource
department could be restricted to a gateway that
allowed access to only the Internet. A member of
the human resource department could send and
receive e-mail and access the Internet, but would
be prevented from accessing servers or hosts on
the local corporate network.

DHCP Server (for AP mode only)
DHCP (Dynamic Host Configuration Protocol) is a networking protocol that allows administrators to assign
temporary IP addresses to network computers by “leasing” an IP address to a user for a limited amount of time,
instead of assigning permanent IP addresses.
The TAP-213 can act as a simplified DHCP server and easily assign IP addresses to your DHCP clients by
responding to the DHCP requests from the client ends. The IP-related parameters you set on this page will also
be sent to the client.
You can also assign a static IP address to a specific client by entering its MAC address. The TAP-213 provides
a Static DHCP mapping list with up to 16 entities. Be reminded to check the Active check box for each entity
to activate the setting.
You can check the IP assignment status under Status DHCP Client List.

TAP-213’s STP/RSTP feature is disabled by default. To be completely effective, you must enable RSTP/STP on
every TAP-213 connected to your network. If TAP-213 plays a Client 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. TAP-213s support STP/RSTP in AP mode only.

We recommend you set an edge port for the port, which is connected to a non-STP/RSTP sub-network or an
end device (PLC, RTU, etc.) as opposed to network equipment. This can prevent unnecessary waiting and
negotiation of STP/RSTP protocol, and accelerate system initialization. When an edge port receives BPDUs, it
can still function as an STP/RSTP port and start negotiation.
Setting an edge port is different from disabling STP/RSTP on a port. If you disable STP/RSTP, a port will not
deal with STP/RSTP BPDUs at all.

SNMP Agent
The TAP-213 supports SNMP V1/V2c/V3. SNMP V1 and SNMP V2c use a community string match for
authentication, which means that SNMP servers access all objects with read-only or read/write permissions
using the community string public/private (default value). SNMP V3, which requires you to select an
authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to
enhance data security.
The TAP-213’s MIB can be found in the software CD and supports reading the attributes via SNMP. (Only get
method is supported.)
SNMP security modes and security levels supported by the TAP-213 are shown in the following table. Select the
security mode and level that will be used to communicate between the SNMP agent and manager.

Link Fault Pass-Through (for Client/Slave mode only)
This function means if Ethernet port is link down, wireless connection will be forced to disconnect. Once
Ethernet link is recovered, TAP will try to connect to AP.
If wireless is disconnected, TAP restarts auto-negotiation on Ethernet port but always stays in the link failure
state. Once the wireless connection is recovered, TAP will try to recover the Ethernet link.
System log will indicate the link fault pass through events in addition to the original link up/down events.

clients, must provide system maintainers with real-time alarm messages. Even when system administrators
are out of the control room for an extended period, they can still be informed of the status of devices almost
instantaneously when exceptions occur.
In addition to logging these events, the TAP-213 supports different approaches to warn engineers
automatically, such as SNMP trap, e-mail, and relay output. It also supports two digital inputs to integrate
sensors into your system to automate alarms by email and relay output.

The TAP-213 has one relay output, which consists of 2 terminal block contacts on the TAP-213’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. For safety reasons, the relay circuit
is kept open when the TAP-213 is not powered.

Trap
Traps can be used to signal abnormal conditions (notifications) to a management station. This trap-driven
notification can make your network more efficient.
Because a management station usually takes care of a large number of devices that have a large number of
objects, it will be overloading for the management station to poll or send requests to query every object on
every device. It would be better if the managed device agent could notify the management station by sending
a message known as a trap for the event.

Save Configuration
The following figure shows how the TAP-213 stores the setting changes into volatile and non-volatile memory.
All data stored in volatile memory will disappear when the TAP-213 is shutdown or rebooted unless they are y.
Because the TAP-213 starts up and initializes with the settings stored in flash memory, all new changes must
be saved to flash memory before restarting the TAP-213.
This also means the new changes will not work unless you run either the Save Configuration function or the
Restart function.
After you click on Save Configuration in the left menu box, the following screen will appear. Click Save if you
wish to update the configuration settings in the flash memory at this time. Alternatively, you may choose to run
other functions and put off saving the configuration until later. However, the new setting changes will remain

Configuring Wireless Search Utility
The Broadcast Search function is used to locate all TAP-213 APs that are connected to the same LAN as your
computer. After locating a TAP-213, you will be able to change its IP address. Since the Broadcast Search
function searches by TCP packet and not IP address, it doesn’t matter if the TAP-213 is configured as an AP or
Client. In either case, APs and Clients connected to the LAN will be located, regardless of whether or not they
are part of the same subnet as the host.
1.
Start the Wireless Search Utility program. When the Login page appears, select the “Device Search only”
option to search for TAPs and to view each TAP’s configuration. Select the “Device management” option to

Other Console Considerations
This chapter explains how to access the TAP-213 for the first time. In addition to HTTP access, there are four
ways to access TAP-213: serial console, Telnet console, SSH console, and HTTPS console. The serial console
connection method, which requires using a short serial cable to connect the TAP-213 to a PC’s COM port, can
be used if you do not know the TAP-213’s IP address. The other consoles can be used to access the TAP-213
over an Ethernet LAN, or over the Internet.
The following topics are covered in this chapter:

The serial console connection method, which requires using a short serial cable to connect the TAP-213 to a
PC’s COM port, can be used if you do not know the TAP-213’s IP address. It is also convenient to use serial
console configurations when you cannot access the TAP-213 over Ethernet LAN, such as in the case of LAN
cable disconnections or broadcast storming over the LAN.
Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the
TAP-213’s USB console port to your PC’s COM port (generally COM1 or COM2, depending on how your system
is set up). After installing PComm Terminal Emulator, take the following steps to access the RS-232 console
utility.
1.
From the Windows desktop, open the Start menu and start PComm Terminal Emulator in the PComm
(Lite) group.
2.
Select Open under Port Manager to open a new connection.
3.
The Communication Parameter page of the Property window opens. Select the appropriate COM port for
Console Connection, 115200 for Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits. Click on
the Terminal tab, and select VT100 (or ANSI) for Terminal Type. Click on OK to continue.
We recommend using Moxa PComm (Lite) Terminal Emulator, which can be downloaded free of charge
from Moxa’s website.

You may use Telnet or SSH client to access the TAP-213 and manage the console over a network. To access the
TAP-213’s functions over the network from a PC host that is connected to the same LAN as the TAP-213, you
need to make sure that the PC host and the TAP-213 are on the same logical subnet. To do this, check your PC
host’s IP address and subnet mask.
Follow the steps below to access the console utility via Telnet or SSH client.
1.
From Windows Desktop, run Start Run, and then use Telnet to access the TAP-213’s IP address from the
Windows Run window (you may also issue the telnet command from the MS-DOS prompt).
2.
When using SSH client (ex. PuTTY), please run the client program (ex. putty.exe) and then input the
TAP-213’s IP address, specifying 22 for the SSH connection port.
3.
The Console login screen will appear. Please refer to the previous paragraph “RS-232 Console Configuration”
and for login and administration.
NOTE The TAP-213’s default IP address is 192.168.127.253 and the default subnet mask is 255.255.255.0 (for
a Class C network). If you do not set these values properly, please check the network settings of your PC host
and then change the IP address to 192.168.127.xxx and subnet mask to 255.255.255.0.

Configuration by Web Browser with HTTPS/SSL
To secure your HTTP access, the TAP-213 supports HTTPS/SSL encryption for all HTTP traffic. Perform the
following steps to access the TAP-213’s web browser interface via HTTPS/SSL.
1.
Open your web browser and type https://<TAP-213’s IP address> in the address field. Press Enter to
establish the connection.
2.
Warning messages will pop out to warn users that the security certificate was issued by a company they
have not chosen to trust.
3.
Select Yes to accept the certificate issued by Moxa IW and then enter the TAP-213’s web browser interface
secured via HTTPS/SSL. (You can see the protocol in URL is https.) Then you can use the menu tree on the
left side of the window to open the function pages to access each of TAP-213’s functions.

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. It is used to indicate that broadcast and
multicast frames buffered by the AP will be delivered shortly. Lower settings result in more efficient networking,
while preventing your PC from dropping into power-saving sleep mode. Higher settings allow your PC to enter
sleep mode, thus saving power.
Fragment
A lower setting means smaller packets, which will create more packets for each transmission. If you have
decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease
overall network performance. Only minor modifications of this value are recommended.
RTS Threshold
RTS Threshold (256-2346) – This setting determines how large a packet can be before the Access Point
coordinates transmission and reception to ensure efficient communication. This value should remain at its
default setting of 2,346. When you encounter inconsistent data flow, only minor modifications are
recommended.
STP and RSTP
The STP/RSTP Concept
Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide protection
from loops. Networks that have a complicated architecture are prone to broadcast storms caused by
unintended loops in the network. The STP protocol is part of the IEEE802.1D standard, 1998 Edition bridge
specification.
Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by
IEEE802.1w-2001 standard. RSTP provides the following benefits:
•
The topology of a bridged network will be determined much more quickly compared to STP.
•
RSTP is backward compatible with STP, making it relatively easy to deploy. For example:
Defaults to sending 802.1D-style BPDUs if packets with this format are received.
STP (802.1D) and RSTP (802.1w) can operate on the LAN ports and WLAN ports (AP, Master, Slave, and
ACC modes) of the same TAP-213.
This feature is particularly helpful when the TAP-213 connects to older equipment, such as legacy switches.

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. The main benefit of RSTP is that the
configuration decision is made locally rather than network-wide, allowing RSTP to carry out automatic
configuration and restore a link faster than STP.

Firmware Recovery
When the LEDs of FAULT, Signal Strength, CLIENT, BRIDGE and WLAN all light up simultaneously and
blink at one-second interval, it means the system booting has failed. It may result from some wrong operation
or uncontrollable issues, such as an unexpected shutdown during firmware update. The TAP-213 is designed to
help administrators recover such damage and resume system operation rapidly. You can refer to the following
instructions to recover the firmware:
Connect to the TAP-213’s ES-232 console with 115200bps and N-8-1. You will see the following message
shown on the terminal emulator every one second.
