Wireless Serial Devices
Quatech announced the release of a line of wireless serial device servers. These serial device servers connect RS-232 and RS-422/485 serial devices to local and wide-area networks without routing Ethernet cables. The devices integrate either Linksys or Cisco Aironet wireless engines with Quatech's ThinQ serial device servers to provide a flexible wireless Ethernet-to-Serial server. Quatech offers the SSEW "L" series, equipped with Linksys wireless connectivity. The SSEW "L" series single port models are available for either RS-232 (SSEW-100L) or RS-422/RS-485 (SSEW-200/300L) applications. Depending on location and signal strength, these units dynamically shift between 11, 5.5, 2 and 1 Mbps network speeds for consistent performance, availability and flexibility. They are interoperable with most IEEE 802.11b-compliant, 2.4 GHz DSSS (Direct Sequence Spread Spectrum) access points, and provide support for 128-bit WEP security protocols. The SSEW "L" models also include a high-powered, built-in antenna. For dedicated Cisco Aironet networks, Quatech also offers the SSEW "C" series. These products install seamlessly into any centralized security protocol (including EAP) used on existing Cisco Aironet 350 Series access points and bridges. The "C" series single port models are also available for RS-232 (SSEW-100C) or RS-422/RS-485 (SSEW-200/300C) applications.
