Paired Mode
Paired Mode
(also called
Serial Tunneling
or
Serial Bridge
mode)
allows
serial devices connected to two ES1AWB serial servers to communicate
across a network. The two ES1AWB serial servers automatically connect to
each other.
In Paired Mode the
heartbeat feature
ensures reliable communications by
restoring the connection if communications are temporarily lost at either end
due to loss of power or Ethernet connection.
Other Communications Modes
ES1AWB Wireless Serial Servers also feature the following communications
profiles:
Modem Emulation Mode
allows you to configure the serial port to operate
as if it is a modem. For legacy applications where a serial device is set up to
communicate through a modem, the serial device can now be connected to
the ES1AWB and communication occurs over the network. The ES1AWB
emulates modem responses to and from the serial device.
In
Console Management Mode
the ES1AWB can be configured for
connection to the management port typically found on network devices such
as routers, switches and servers. This allows remote management of the
network device. Communication can be accomplished using telnet to a
specific port in the serial server.
Custom Mode
allows you to custom configure the ES1AWB serial port and
is used if your application does not fit into any other predefined modes.
802.11 Wireless Networking Basics
ES1AWB wireless serial servers
allow you to connect non-network-enabled
serial devices into a wireless network, giving you the capability to gather
more data and implement remote programming and management. Serial
devices no longer are limited to a physical connection to a PC. The serial
device can be connected to an ES1AWB wireless serial server anywhere
within range of an 802.11b-compatible wireless access point.
Communication occurs transparently using TCP/IP or UDP/IP over a
wireless link. This allows traditional Windows PC software access to serial
devices anywhere on the wireless network.
