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.
