The industrial SW5500 series is compact, rugged (IP50) and cost effective industrial-grade wireless device servers. This series is designed for wireless communication over the IEEE 802.11a/b/g/n network with any device that has a serial interface (RS-232/422/485).

With support for the latest  n  standard and operation on either the 2.4GHz or 5GHz band, the SW5500 series offer superior signal strength and the flexibility required to achieve excellent wireless performance.

The model SW5501 features 1 DB9 serial port (RS-232/422/485) interface. It comes with dual antenna design which offers better wireless cover safe and reduces wireless blind spots

By encapsulating serial data and transporting it over Wireless LAN or for security requirements by WEP or WPA2-PSK compatiable (supported TKIP/AES encryption). SW5001 offers full-duplex, bi-directional data transmission transparent between serial port and Wireless LAN.

In industrial and manufacturing automation fields, SW5500 series is used as a field device to connect the Ethernet through TCP/IPv4 protocol directly. It is also specially designed for conjunction with PLCs, HMIs, Barcode Scanners, Data Terminals, Electronic Kanbans, Shop Floor Control Systems, and Pick-to-Light Systems.

This unit is the replacement product of the end-of-life SW5001, which we've currently put the last two units on clearance for a quick sale. This unit has a 5 yr warranty
