Product Overview
The SW550X Industrial Wireless Serial Device Server is designed to provide wireless connectivity to clients and
serial devices, thus creating a complete solution for your industrial wireless networking. The SW550X series can
be operated as a wireless client with the ability to connect serial device to Wireless Local Area Network (WLAN) or
Local Area Network (LAN) and as AP client to bridge between WLAN and LAN.
The SW550X Series support IEEE 802.11a/b/g/n wireless connectivity standards, which can be operated in both
2.4GHz and 5GHz bands. It acts as a server for serial devices that are connected to its ports in order to transparently
connect to other devices in the wireless network or can be reached by other wireless devices. Supported interfaces
of serial devices include RS-232, RS-422, and RS-485.
As an example, user can connect serial devices to a Wireless Serial Device Server (SW550X) and control them
through Wireless Networking Device such as Wireless Access Point (AW5500) in wireless local area network
(WLAN). An example in Figure 1.1 illustrates how to connect serial devices to a wireless local area network or a
backbone network. The SW550X Industrial Wireless Serial Device Server provides several functionalities to support
mobile and wireless networking.
