1-Port (RS232/422/485) Industrial IEEE802.11b/g/n Wireless Serial Device Server, w/Bridge Mode *** Power Supply Not Included ***

The Antaira STW-611C is an industrial wireless serial device server with IEEE802.11b/g/n in 2.4GHz band that provides connectivity to clients and serial devices creating a complete solution for wireless networking.

It has an IP50 rated and compact rugged aluminum case design with a wide operating temperature that can support -10° to 60° C. It also encompasses a high EMC protection to meet industrial application requirements.

Antaira’s STW-611C includes built-in advanced features “bridge” mode to allow any serial and Ethernet device to link with a wireless network – in order to perform a “3-way communication” solution. This unit also has a hassle free “Wi-Fi direct” technology which offers easy setup for a “point-to-point” application via a “push button” method that does not require any software configuration.
