4.1 Overview Information
AW5500 is an Industrial Wireless solution for applications in harsh environments. The AW5500
is tough enough, expected to operate at temperatures ranging from -10°C~60°C. The ease of
installation makes it attractive as it uses a DIN-Rail for fixing itself to virtually any surface in
your workplace. Reliability is a key factor when wireless solutions are needed, that is why
AW5500’s size makes it ideal for small places when considering its positioning without
affecting real-time, control and overall performance.
4.2 User Interface Overview
AW5500 series’ Web Configuration is designed into three different modes for ease of use to
suit customer needs. The Web Configuration appears as follows,
Figure 4.1
On the left side, a menu-tree appears with all the modes and options available, while on the
17
Atop Industrial Wireless Access Point

right side of your screen the contents of each mode/option will be displayed in a graphical state.
Since each Mode of operation is different, the content will differ, for more information on each
selection please refer to each option’s Section throughout the manual.

In general, there will be three buttons which will be present at the end of almost each
configuration:
Table 4.1
4.3 Secure Wireless Network
AW5500 is designed to provide you security support when building a network. We recommend
using WPA2-PSK with AES as a minimum when securing your network; also remember to set
it at 802.11n for a full speed performance. For more information on this and more please read
Security Settings.
4.4 Wireless Settings
Wireless Settings includes the basic Wi-Fi settings and wireless security. There are however,
some concepts to be mentioned before going one step forward on the wireless settings. As
you know, 802.11 is a set of standards for WLAN communication at the 2.4, 3.6 and 5 GHz
frequencies. The AW5500 works only with the 2.4 and 5 GHz range. it follows the below
mentioned standards:
802.11a; (also known as 802.11a-1999), is a 54 Mbps (around 20 Mbps net throughput),
5 GHz signaling standard; since 2.4 GHz is used by a big number of different devices
interference here is less than in 802.11b. However, signals will not penetrate as much as
802.11b because they are absorbed more readily by walls and other solid objects (when
on a single path), but not when use in multi-path environments i.e., indoors, office.
802.11b; the first of the standards to be created; an 11 Mbps (4~5 Mbps net throughput),

2.4 GHz signaling standard. Although it performs much better than traditional dial-up
networking, its performance is still significantly less than 802.11a and other, newer
standards.
802.11g; very similar to 802.11b, the main difference being that it is done in a maximum
raw data rate of 54 Mbps (20 Mbps net throughput), at the same 2.4 GHz bandwidth
802.11n; Improves the amount of bandwidth utilized by using multiple wireless signals
and antennas (MIMO technology) instead of one. Link speed on a 2x2 solution is 300
Mbps on our models.
4.4.1 Wizard
AW5500 comes with a Quick Setup Wizard that will guide you through most of the common
settings. You might find it suffice to follow the wizard and setup the Access Point without the
need to proceed with this manual, (again, this is only applicable for the most basic setups in
each mode).
4.4.2 Basic Settings
To set up a wireless network, several parameters are needed as shown in Figure 4.7. Link
Speed can be optimized up to 300 Mbps by choosing 802.11 b/g/n or 802.11a/n; again,
remember that 2.4 GHz frequency is easily interfered by other devices that operate in the
same region (namely, Bluetooth, Zigbee, Microwave, etc.) so it is better to choose the
802.11a/n which operates in the 5 GHz when your network allows it. Below there is a table
which shows Basic Settings for the device, Table 4.2.
Table 4.2
20
Atop Industrial Wireless Access Point
AW5500
User Manual V. 1.3
The basic settings are explained in detail below:
Radio On: AW5500 supports up to three multiple SSIDs (AP1, AP2, and AP3).AP1 must
be enabled before you can proceed to AP2 and AP3. AP2 and AP3’s settings are only
shown when they are enabled. When all three APs are disabled, wireless radio would
turn off completely.
SSID: specifies the device’s wireless network name that other wireless devices should
use in order to associate with this AP. Each AP (AP1, AP2, and AP3) can have their own
SSID for better wireless network management. You can use the “Scan network”
function to learn about the different SSIDs and channel numbers in the device’s
surroundings, please be patient as this process might take as long as 10 seconds as
shown below. Once it has finished scanning, names and basic properties of neighboring
networks will be shown as in Figure 4.4. When no neighbors have been found the answer
is as follows Figure 4.5. Keep in mind that the SSID should be unique unless wireless
roaming is required.

SSID Broadcast: allow any wireless client to search for this access point presence, it is
enabled by default. When the SSID Broadcast is disabled, wireless clients need to
manually input the SSID in their wireless client configuration, increasing network security
to prevent an access from unsolicited clients.
Wireless Mode: The modes are separated into two parts by different colors. The modes
colored in green denotes the modes that runs on the 2.4 GHz frequency and the modes
colored in red denotes the modes that runs on the 5 GHz frequency. Please note that the
2.4 GHz frequency is very crowded and usually does not reflect the real performance of
the device, please consider using the 5 GHz frequency when possible.
Channel: Select “Automatic Channel Select” to let the device automatically assign the
best available channel number. When setting the channels manually, bear in mind that
23
Atop Industrial Wireless Access Point
AW5500
User Manual V. 1.3
channels 1, 6, and 11 are the non-overlapping channels for 2.4 GHz Figure 4.6. Again,
you can use “Scan network” to see which channels are already occupied.
Bandwidth: when 40 MHz is used, AW5500 will double the channel width to 40 MHz as
compared to the standard 20 MHz to transmit its data; this is not recommended for
802.11b/g/n since it will leave only one non-overlapping channel for other APs. HT40 (40
MHz), is recommended for 802.11a/n because it offers a wider frequency range and it is
easier for AW5500 to find empty channels as well.

A number of Security Settings are available for you:
WEP 64/128-bit Hex: stands for Wired Equivalent Privacy. Which is a moderately weak
security algorithm, and although it implies security in a wired connection, it is weaker than
WPA protocols. It is not recommended unless a really large network is being
administered. Up to 4 different hexadecimal or ASCII keys can be entered in this section,

AW5500
User Manual V. 1.3
AW5500 provides two SNMP fields, which are “System Contact”, usually used to specify the
device’s contact information in case of emergency; and “System Location”, usually used to
specify the device location.
If you wish to make the device information available for public viewing/editing, Enable the
SNMP function. Fill in the passphrase for the “Read Community”, the group that is allowed to
read the device information and fill in the passphrase for the “Write Community”, the group
that is allowed to read/modify the device information. By default AW5500 comes in public for
Read Community and private for Write Community. In case the device raises an alert due to
any unexpected incident, a message will be dispatched to a SNMP trap server. Specify the IP
Address of the SNMP Trap Server designed to collect all alert messages; any changes made
will take effect after the device is restarted.

4.7 Email Settings
In case the device raises an alert and/or warning message, it will send an email to the
administrator’s mailbox. Email Settings allows you to set up the device to be able to send an
email. To set up the email sending, you need to put a “Sender” email address which will be
the “From” on the email. Then, you fill in “Receiver” email address to which the email is sent.
You can send the email to several recipients using Semicolon (;) to separate each email
address. Next step is to set the Email Server. First, you fill in the IP address of a Mail Server
in your local network. If the Mail Server needs a user authentication, you need to enable
“SMTP server authentication required”, and fill in Username and Password. Please
contact your network administrator for Mail Server IP address and the Username and
Password, Figure 4.22. You can click on “Send Test Mail” to verify your mail settings.

4.8 DHCP Server
If there is no workstation or server to act as the DHCP Server and assign IP addresses to each
client automatically, AW5500 can serve as the DHCP Server to statically or dynamically assign
an IP address to any network device. To enable such functionality, check Enabled to enable
the DHCP Server in AW5500; proceed then to fill in the IP Address Range including the
“From IP Address” and “To IP Address”, fill in the IP address’ Netmask (or Subnet Mask).
“Lease Time” is the duration in minutes that an assigned IP Address will belong to that device;
once expired, the IP address will be recycled. A maximum of 21600 minutes is set by default.
You can also assign a static IP address to a network device, meaning that the network device
would always get the same Static IP Address from the DHCP server. To statically assign an IP
address, check on the small box in front of each line, and then fill in the Host Name and/or the
MAC Address that you want to assign a static IP Address to. When DHCP is enabled, up to
32 different static IP/MAC can be set, Figure 4.23.

4.9 Firewall & Filtering
The following section deals with configuration for the network’s firewall as well as its packet
filtering. Available criteria for packet filtering are based on MAC address (Wired or Wireless),
Ethernet packet, and IP address. These filtering methods provide security, preventing
unauthorized or malicious packets an entrance to your network.
Data packets will be filtered (classified) as either “allowed packets” or “denied packets”;
the “allowed packets” mode is more commonly known as the “whitelist” and the “denied
packets” mode is known as the blacklist. We highly encourage you to be extremely careful on
this section as data that doesn’t fit into any of those criteria will be discarded with the potential
outcome of letting the AW5500 as inaccessible if not configured properly. If the latter happens,
you will need to reset the device back to its default by any of the methods described in Reboot
and Restore Default Settings.

4.9.1 Wired MAC Filtering
When connected to the LAN/Ethernet interface, filtering can be done using this option. The
setting is simple, intuitive and straight-forward; just choose whether to Allow or Deny packets
and proceed to fill in the blanks with the corresponding MAC addresses. Up to 64 different
MAC addresses can be set for allowing as well as for denying packets, Figure 4.25; as a
default, Wired MAC Filtering is disabled. For changes to take effect, press Apply, for saving
those changes just press Save Settings.

4.9.2 Wireless MAC Filtering
Packet filtering in a Wireless environment can be done in an analogous way as the Wired MAC
Filtering. In the same way, connection is ensured by allowing or denying packets according to
their respective MAC addresses; again, a maximum of 64 different MAC addresses are
available as an option, Figure 4.26.

4.9.3 Ethernet Type Filtering
Ethernet Type Filtering is done according to the packets’ Ethernet type, also known as
Layer 3 filtering. As in the two previous sections, there is a maximum of 64 entries for packets’
specification. Enabling is simple (packets are set as disabled by default, Figure 4.27),
checking the packet’s Ethertype box (located to the left of it, first column). Ethertype
numbering usually starts with 0x, in which corresponds to a hexadecimal
number, e.g., 0xF0F0 which is to filter NETBUI type messages or 0x8035 for RARP type
messages; Figure 4.27.

4.9.4 IP Filtering
IP Filtering, as its name implies, is for filtering on the IP protocol, also known as Layer 4
filtering. Continuing its simple design, IP address is added on the Source and Destination
Address fields. Each filter only provides a one-way filtering, to create a 2-way filtering you
need to add another entry that has the source and destination address reversed. The filters
should be active once the checkbox in the first column is checked. A total of 64 different entries
can be added to the list, Figure 4.28.

5 Operation Modes
5.1 Regular AP Mode
Regular AP mode’s welcome screen is as shown below, Figure 5.1.
Regular AP mode which is the factory default and the first option on the screen, allows
wireless clients to connect to a network, relaying data between the wired and wireless devices
in the network. It allows multiple wireless clients to access the network through AW5500’s
Ethernet interface (physical/wired connection). Its corresponding complete menu-tree is as
follows in Figure 5.2.

71
Atop Industrial Wireless Access Point
AW5500
User Manual V. 1.3
On operation mode choose “Regular AP” (if the device is not in factory default).
Go to Wireless → Basic Settings; here you can change the Network Name (SSID) to
your preferred name, you might want to first click on “Scan network” to find whether
there are neighbors with a name matching yours (this is done for preventing any conflict
over networks).
At this point you may decide to change other settings such as the Wireless Mode and
whether to have Automatic Channel Selection.
Next go to Security Settings, and on Security Mode choose which security protocol will
be used in the network. We strongly recommend not leaving this section as disabled.
On LAN & WLAN Interfaces, enter the IP Address, Subnet Mask, Default Gateway,
and DNS servers used (if any), according to your network configuration.
Click “Apply”, and wait for the changes to take effect. You may also want to Save
Settings afterwards just in case you need these configurations in the future.

5.2 WDS Bridge Mode
On this mode multiple AW5500 can bridge together to create a Wireless Distribution System.
Under this mode, the device uses its second MAC address as its wireless interface instead of
the first one. The following details the WDS structure; there are three roles that AW5500 can
play in a WDS network:
Root AP (or Root)
Hybrid (or Parent)
Station (or Child)
Please keep in mind that there should be one and only one Root AP in the WDS network.
Hybrids can connect to a Root AP or connect with each other and Stations can connect with
either a Root AP or a Hybrid. Connecting multiple WDS nodes to a Root AP or a Hybrid is
allowed as well. Please take a look at the following tree structure, Figure 5.3.
Figure 5.3
73
Atop Industrial Wireless Access Point
AW5500
User Manual V. 1.3
Note: it is possible to setup a Hybrid (Parent) without a Station (Child). The difference between a Hybrid and a Station
is that the Station does not allow wireless clients to associate to it.
For AW5500 quick steps to work as in WDS Mode, the procedure is as follows:
On operation mode choose “WDS Bridge”.
Go to Wireless → Basic Settings; on WDS Mode you can choose whether to use the
AW5500 as a Root AP, Hybrid, or Station. Also as before, you can change the Network
Name (SSID) to your preferred name; you might want to first click on “Scan network” to
find whether there are neighbors with a name matching yours (this is done for preventing
any conflict over networks). From here three different configurations are therefore
possible:
When on Root mode
SSID Broadcast can be disabled here for an additional level of security.
On Wireless Mode, we recommend using 802.11 a/n since it is not as
crowded as 802.11 b/g/n; however this is only possible if it is supported by
your wireless client. Channel and transmission rate can be chosen
automatically by the AW5500, however feel free to change them to the
settings that work for you.
On WDS Settings → Encryption Type, do not leave this option as NONE,
non-existent encryption will result in an easy target for undesired access to
your network.
On Root AP, the MAC address is to be left empty; again the Local Area
network fields should be entered with their corresponding values for the
network being configured.
Save and apply the settings for them to take effect.
When on Hybrid mode
Please remember that the SSID here should be the same as the Root AP. This
also means roaming is possible between APs.
On WDS Settings → Root AP, the MAC address entered should be the
Root/Hybrid’s (Parent’s) Second MAC address that is directly above this
Hybrid AP. It might not be the Root AP’s MAC address if the WDS setup has
a multilayer architecture.
Save and apply the settings for them to take effect.
74
Atop Industrial Wireless Access Point
AW5500
User Manual V. 1.3
When on Station mode
SSID is not present here as there is no AP function
On WDS Settings → Root AP, the MAC address entered should be the
Root/Hybrid’s (Parent’s) Second MAC address that is directly above the
Station AP. It might not be the Root AP’s MAC address if the WDS setup has
a multi-layer.
Save and apply the settings for them to take effect.
Its corresponding menu-tree has slight differences compared to Regular AP, Figure 5.5.

5.3 AP Client Mode
This mode allows your AW5500 to connect to an AP. Ethernet clients connected to AW5500
over the Ethernet interface are allowed to access the network through AW5500’s wireless
interface. Under this mode, the device uses its second MAC address as its wireless interface
instead of the first one.
Remember that your AW5500 can function as both a Regular AP and as an AP Client (the
latter connected to the first one).
Supposing we already have the network physically installed, the steps for configuring your
AW5500 as an AP Client are as follows.
On Operation Mode choose AP Client.
Click on “Save Settings”, go then to Mobile Station under the Wireless section and
click on “Scan network” to choose an SSID.
A window/tab will pop out; in that new window/tab, there will be the names of the
surrounding Wireless Networks. Choose the one that you already designated as your
Regular AP by selecting its corresponding SSID.
Click “Connect”, this will make you close the pop-out window/tab, and leave you with
the settings selected on the previous page.

Enter the WEP key or the WPA passphrase if necessary.
Scroll to the end of the page and press “Apply”, please wait for some time for the
changes to apply.
Then proceed to go to System Information, on the AP Client Information you can
confirm your AW5500 is connected to the Network selected if the status field displays a
signal percentage instead of disconnected. Also, you may also double check the wireless
connection status inside the client table of the connected AP.

6.2 Basic WDS Setup
The following figure illustrates two sites with some considerable distance apart. Ethernet
cabling is impossible to the adjacent site. The adjacent site has both wireless clients and
Ethernet clients. Note that if the Access Point function is not required at the adjacent site (no
wireless clients), WDS Hybrid can be changed to WDS Station.

6.3 Coverage Range Extender Setup
Extending from the above scenario, if the distance needs to be further extended, it is always
possible to add more AW5500 (in WDS Hybrid mode) in between the existing one. The WDS
MAC address of the newly added AW5500 (in WDS Hybrid mode) should be MAC address
of the AW5500 that it is directly connecting to, not the MAC address of the AW5500 in WDS
Root mode. Note that AW5500 in WDS Station mode does not allow both wireless client and
AW5500 (in WDS Hybrid mode) to connect in. Normally it should be the last AW5500 in the
wireless topology if utilized.
For more information on how to configure your AW5500 for this topology, please refer to WDS
Bridge Mode.
Note: wireless coverage is dependent on the environment.

6.4 AP Client Setup
If AW5500 is being added to a wireless network where Access Points (AP1) from other
vendors already existed, AW5500 could be set to AP Client mode to connect to that AP1 and
bridge the Ethernet clients to AP1. This setup is similar to Scenario #2, except that WDS is not
used. This is because WDS from different vendors might not be compatible.
