About Your LWS300A Wireless Serial
Server
LWS300A Wireless Serial Servers
are part of Black Box growing family of
device servers, products that allow you to connect equipment with available
serial connections into existing networks. LWS300A wireless serial servers
connect RS-232, RS-422 or RS-485 devices to a wireless network via
wireless access points, eliminating the need for network cabling. Based on
the 802.11b wireless standard, LWS300A servers operate at up to 11 Mbps
over the 2.4 GHz band, which does not require licensing.
LWS300A wireless serial servers are built for use in industrial environments
and feature rugged DIN or panel mountable enclosures. They feature a wide
DC power supply range and removable screw terminal power connectors.
A serial device connected to the serial port on your LWS300A can be
accessed from any node on the LAN using
virtual COM port, console
management, TCP and UDP socket, serial bridge, terminal, modem
emulation
and
custom connections
. Network addresses can be obtained
dynamically or manually. Simple Network Management Protocol (SNMP) is
supported. Configuration is accomplished through a web-based user
interface.

Communication Modes
LWS300A Wireless Serial Servers
allow you to connect serial devices over
a wireless network. The connection can be configured in several modes.
Direct IP
Direct IP Mode
allows applications using TCP/IP or UDP/IP socket
programs to communicate with the asynchronous serial ports on the serial
server. In this mode the LWS300A is configured as a TCP or UDP server.
The socket program running on the PC establishes a communication
connection. The data is sent directly to and from the serial port on the server.
•
TCP Server Mode
allows network devices to initiate a TCP connection
to the serial device connected to the serial port on the LWS300A. This is
also referred to as reverse telnet.
•
UDP Server Mode
allows network devices to initiate a UDP connection
to the serial device attached to the serial port of the LWS300A. When
using UDP protocol the LWS300A can be configured to broadcast data
to and receive data from multiple IP addresses.
