2 General Concepts

2.1 Configuration Methods

The BAT-C supports four main concepts for setting and configuring the BAT-C:

1. SMART mode. Use the buttons and LEDs on the BAT-C to setup automatically.

2. Web interface. This is a Graphical User Interface with the common settings for the BAT-C.

3. AT commands. Connect to the BAT-C over Ethernet using TCP or directly on Layer 2 and use a
terminal like HyperTerminal to issue AT commands. Everything you can do in the Web interface
and much more is supported using the AT commands. See CLI-Reference for more information.

4. The SNMP protocol. See CLI-Reference for more information.

2.2 Using the SMART configuration mode

To enter the SMART configuration mode press the mode button within 5 seconds from power
up. The LEDs above the button (marked A, B, C and D) will show which mode is selected.
When you select the preferred mode, confirm it by holding the SMART button for two
seconds. This will cause the LEDs to start flashing during the duration of the operation of the
selected mode.

There are currently 12 different modes:

Use the "Enable DHCP server" option to access the BAT-C if the PC is using DHCP without
having to change the PC IP settings. Use this option when directly connecting the PC to the
BAT-C. Enable this mode, and then connect the Ethernet cable to the computer. When a
reboot occurs, the DHCP server disables.

Later we will describe how to use the other different modes for a specific application.

2.3 Using the WEB configuration

By default, the BAT-C is a DHCP Client and Relay that has an IP address: 172.23.56.99,
subnet mask: 255.255.255.0 and default gateway: 172.23.56.99. To access the BAT-C by

BAT-C

Release 02 05/2016

11

the Web based configuration interface the computer must be set up in the same network, i.e.
IP address: 172.23.56.1 and subnet mask: 255.255.255.0.

Open a web browser and enter http://172.23.56.99 in the address bar. Here you will find the
common configuration parameters needed to setup a connection. If the device is set to the
factory default, you will need to login using the password private before configuring the unit.

When the BAT-C receives an IP address from DHCP Server, then use the IP address to
access device.

Below is an example of the WEB interface.

2.4 Reset to factory defaults

It is possible to reset to factory settings in 3 different ways.

1. Enter and confirm SMART mode 2.

2. Issue AT&F.

3. Hold the mode button while the BAT-C is starting.

Note: Verify that the Ethernet cable is disconnected and stop any firmware updates.

2.5 Wireless LAN modes

A Wireless LAN network can be set up in two main connection modes:

1. AD-Hoc mode. Used typically, when two WLAN devices are connected to each other without
going through a WLAN Access Point. In Ad-Hoc mode, the 802.11b transmission speeds are
used. This means a maximum of 11 Mbit/s. The WEP encryption method is available.

2. Managed (or Infrastructure mode). Used typically, when connecting a group of devices through
a common WLAN Access Point. In this mode, transmission speeds, up to a maximum of 54 Mbit/s,
are available. This also allows users to select which encryption and authentication methods to
use.

This means applications supporting the Managed mode normally have a higher throughput.

2.6 BAT-C modes

There are three main "BAT-C modes" supported by the BAT-C. Applications descriptions will
refer to these modes later in this document.

1. Ethernet Bridge mode. Two BAT-C’s connected together support this mode. In this mode, the
two BAT-C’s transparently transfer encapsulated UDP packages Ethernet packages. Devices on
both sides of the wireless link are unaware of the wireless connection. For example, an Ethernet
network with several devices connected through an Ethernet switch or hub.

2. Client mode. In this mode, the BAT-C is acting as a wireless extension of the cable connected
Ethernet device. Configure the BAT-C to take over, clone, the MAC address of the connected
device. This means that you connect ONE Ethernet device at a time to each BAT-C.

3. Multi-Client mode. In this mode, the BAT-C is acting as in Client mode but with the addition of
connecting several devices using the IP layer.

The Ethernet Bridge mode will introduce an extra overhead (because of the encapsulation)
and will have a significant lower throughput than Client/Multi-Client mode.

2.7 WLAN Security

The BAT-C supports different authentication and encryption methods. The BAT-C supports
the following authentication methods:

► Open connection
► Shared secret
► WPA and WPA2 Pre-shared key
► LEAP
► PEAP

The BAT-C supports the following encryption methods:

BAT-C

Release 02 05/2016

14

► No encryption
► WEP64 (RC4)
► WEP128 (RC4)
► WPA (TKIP)
► WPA2/IEEE (AES)

The following table shows valid combinations of authentication and encryption methods (x
means valid configuration):

Open connection

Shared secret

WPA/WPA2 PSK

LEAP

PEAP

No encryption

x

WEP 64

x x

x WEP 128

x x

x

TKIP

x (WPA)

x

x

AES/CCMP

x (WPA2)

x

x

Examining the table above you will see that, if you select WPA/WPA2 PSK with TKIP, this is
a WPA connection. If you select, WPA/WPA2 PSK with AES/CCMP, this is a WPA2
connection. Please refer to the table above when selecting your encryption and
authentication methods.

If you wish to use LEAP or PEAP as the authentication algorithm, verify that your access
point supports it. The Open connection and Shared secret authentication methods are
available in ad-hoc mode.

2.7.1 Key management

For WEP64 and WEP128 shared keys can be entered into the four possible slots made
available by the AT*AGFPWI Write Encryption/Authentication Key (with Index) command.
However, for LEAP, PEAP and WPA/WPA2 PSK enter the password or PSK into the key slot
with index 1 (one). This key must also be the one currently to set active by the AT*AGAFP
Active Encryption/Authentication Key command.

In the following list you will find the possible Key lengths:

► WEP64 (40 bit) 5 ASCII or 10 HEX characters
► WEP128 (104 bit) 13 ASCII or 26 HEX characters
► WPA/WPA2 (IEEE 802.11i) between 8 and 63 ASCII characters

If you are using LEAP or PEAP, the username for the Radius server should be entered with
the command “AT*AGUN Username” and the domain with command “AT*AGDN”. For PEAP,
consider certificate management. When receiving the certificate from the Radius server, the
SHA-1 fingerprint is calculated and stored in the BAT-C for future comparisons. Enter the
new fingerprint or clear the old one with the command “AT*AGCFP” when the certificate
changes or you want to use a different Radius server.

If you are using WPA/WPA2 PSK authentication enter either, the pre-shared key, i.e. the
hexadecimal string or the password, in plain text, commonly referred to as “WPA-PSK” and
“WPA-PWD”. If you select to enter a password, rather than a hexadecimal string, the BAT-C

BAT-C

Release 02 05/2016

15

will take a few seconds longer during the next connection after this change, in order to
deduce the real key from the password. While the BAT-C is calculating the real key, it will be
unresponsive.

By default, the device enters the key as an ASCII string. To enter a hexadecimal key,
separate the bytes using a “\” character, i.e. to enter the string "12345" as hexadecimal, type
"\31\32\33\34\35".

3.12 Multi-Client mode

Operation

Multi-Client mode mode

Encryption

WEP/ WPA/ WPA2 (IEEE 802.11i)

Ove r v i ew:

The Multi-Client mode is used when there is a need to have several devices, 3 and 4 in
figure above, behind the BAT-C that communicate with 1 and/or 2. The restriction is that one
device at a time can use Layer-2 communication while the others need to use the IP layer.

When configuring the BAT-C in the Client mode and there is no link on the Ethernet port, it
will use a temporary Multi-Client mode instead. Once there is an Ethernet link, the BAT-C will
revert to the Client mode.

If devices want to use DHCP over the BAT-C connection while in the Multi-Client mode. The
built-in DHCP relay can be switched on using “AT*ANDHCP” and the Web-Interface. Verify
that the device forwards packets correctly.

3.12.1 How to setup this example?

The Multi-Client mode is configured using “AT*ACEW” and the Web-Interface if no Layer-2
communication is required. The MAC-address for AT*ACEW can be set to the Ethernet
MAC-address.
