2-Port Industrial RS-232/422/485 To Wi-Fi Device Server (EOT -20°C ~ 70°C) *** Power Supply Not Included ***

The STW-602C is a gateway between Ethernet (TCP/IP) and RS-232/422/485 communications. It allows almost any serial device to be connected to a new or existing Ethernet network. The STW-602C offers a wireless network interface (IEEE802.11g, 54Mbps) and two serial ports. By encapsulating serial data and transporting it over Wireless LAN; or for security requirements by WEP or WPA encryption, the STW-602C offers full-duplex, bi-directional data transmission transparent between serial port and Wireless LAN. The STW-602C uses Virtualcom software to create com ports on the computer preventing the need for physical serial ports on the computer. All standard forms of serial RS232, RS422 or RS485 are accepted by the STW-602C.
