1.0 Introduction
ATC-2000WF Series of wireless serial device servers give you an easy way to connect
your RS-232/422/485 serial devices to a WLAN. The 1-port ATC-2000WF and 2-port
ATC-2002WF are ideal for environments where a LAN is not available, or where serial
devices are moved frequently.
1.1 Overview
The RS232 connection application has been used for a long time. RS232 cable has
limitations in distance. WLAN (Wireless Local Area Network) has become a worldwide
standard protocol for wireless applications. There are many applications for using RS232
connection over WLAN, including POS, data capture, telemetry, PLC controllers, remote
control, vending machine, industrial control, and others. The device that supports
connection over WLAN is called as Wireless to Serial Server. Through out the guide, the
802.11g Wireless to Serial Server will be referred as the“Server”.
ATC-2000WF wireless serial device servers support automatic IP configuration protocols
(DHCP, BOOTP) and manual configuration via a handy web browser console. Both IP
configuration methods ensure quick and effective installation, An external antenna
increases the range of the wireless connection. Users can position the adjustable antenna
for maximum signal strength or even replace the antenna with their own for additional
flexibility and scalability. This feature is particularly useful when a serial device is
connected in a high interference area. As an added feature, a signal strength indicator is
located on the front panel to make it easier to troubleshoot connection Problems.
ATC-2000WF wireless serial device servers ensure the compatibility of network software
that uses a standard network API by providing TCP Server Mode, TCP Client Mode, and
UDP Mode. The Real COM/TTY drivers allow software that works with COM/TTY ports to
be set up to work over a TCP/IP network in no time. This excellent feature preserves your
software investment and lets you enjoy the benefits of networking your serial devices
instantly.
To make your management task easier, the ATC-2000WF provides additional features,
such as password authentication, IP filter, WEP support for 64-bit and 128-bit encryption,
and SNMP support.
