FEATURES
• Use your tried-and-true serial equipment
over a wireless network.
• Ideal in areas where running cable is not
an option.
• Use in applications requiring COM ports,
serial tunneling, TCP, or UDP sockets.
• Perform remote device monitoring
and diagnostics.
• Comply with the 802.11g (54-Mbps) or
the 802.11 b (11-Mbps) standard.
• 802.11g servers provide backward
compatibility with 802.11b equipment.
• Rugged IP30 enclosure offers DIN rail or
panel-mount options.
• Security features include WEP, WPA, EAP,
Cisco LEAP, and passwords.
OVERVIEW
BLACK BOX®Wireless Serial Servers provide easy access
to industrial serial devices such as PLCs, motor controls, and
process analyzers across your wireless 802.11g or 802.11b
Ethernet network.
The servers are built for heavy-duty industrial applications.
They’re housed in rugged IP30-rated metal cases and are DIN
rail or panel mountable. They feature terminal block power
connectors for redundant, wide-range AC/DC power.
The servers are fully compliant with IEEE 802.11g, which
brings data rates up to 54 Mbps using OFDM (Orthogonal
Frequency-Division Multiplexing) technology. Because it’s
backward compatible with 802.11b, an 802.11b access point
can interface directly with a Wireless Serial Server. An omni-
directional antenna is included.
Wireless Serial Servers come in RS-232, RS-422/485, and
RS-232/422/485 interface options for a variety of serial devices.
The LWS402A and LWS404A feature MEI ports, which enable
you to connect any RS-232, RS-422, or RS-485 device.
The built-in Web server enables you to easily configure
Wireless Serial Servers using any standard browser. The
servers are compatible with Windows®98/Me/2000/XP,
and Windows NT®4.0.
Complete Security
The server includes full wireless security: 64- and 128-bit
WEP, WPA, EAP, and Cisco LEAP.
Wired Equivalent Privacy (WEP) encrypts data packets well
enough to keep out most eavesdroppers. WEP encrypts each
802.11 packet separately with an RSA RC4 cipher stream
generated by a 64- or 128-bit RCA key.
Wi-Fi®Protected Access (WPA) uses dynamic session keys
called Temporal Key Integrity Protocol (TKIP) to address the
problem of users who don’t enable WEP or who don’t change
the default key. TKIP automatically derives its encryption
keys from a master key using a mathematical algorithm and
changes the keys at regular intervals. This eliminates the
problem of people who forget to change keys.
WPA depends on the 802.1x protocol, which incorporates
the Extensible Authentication Protocol (EAP). EAP
enables authentication between a client device and the
authentication server. Like WEP, WPA uses the RC4 stream
cipher.
Cisco Lightweight Extensible Authentication Protocol
(LEAP) provides username/password-based authentication
between a wireless client and a RADIUS server. With Cisco
LEAP in place, a LAN station cannot pass traffic through the
Wireless Serial Server until it authenticates itself.
Additionally, the servers include password security for
configuration and administration.
