Secure iWiFi is a serial-to-WiFi device server that enables installed devices to connect through their existing serial port to the internet over an 802.11b/g wireless LAN.

Secure iWiFi acts as a security gap between the host application and the network. It provides one secure SSL3/TLS1 socket; supports up to 10 simultaneous active TCP/UDP sockets and two listening sockets; a web server with two websites; SMTP and POP3 clients; MIME attachments; FTP and Telnet clients, and SerialNET mode for serial-to-IP bridging.

Secure iWiFi eliminates the need for any hardware modifications to the host device. Simply connect a serial cable from Secure iWiFi’s RS232 or RS485 connector to your device. Secure iWiFi is ready to connect to the WLAN via its integrated antenna.

The internet engine inside Secure iWiFi is Connect One’s remotely updateable iChip CO2128 Secure Internet Controller.

Connect One’s AT+i protocol eliminates the need for internet programming and minimises changes to the host application. Connect One’s SerialNET operating mode completely eliminates the need for changes to the host application, as it is a true plug-and play operating mode.

Secure iWiFi is powered by an external 9VDC power supply. Alternatively, it can be powered through pin 9 of the RS232/RS485 connector to the host device. It includes a power save mode for reduced power consumption.

Application program interface:

  • Connect One’s AT+i protocol
  • SerialNET mode for transparent serial data-to-Internet bridging

Internet protocols:

Security protocols:
SSL3/TLS1, AES-128/256, SHA-1, HTTPS, FTPS, RSA, 3DES, RC-4, MD-5, WEP, WPA and WPA2.

  • Flow control: hardware (DTR, RTS, CTS, DSR) and software flow control

Secure iWiFi firmware and device configuration parameters can be remotely updated over the internet. Secure iWiFi can be easily configured via Connect One’s iChipConfig utility.

This Windows-based utility enables quick configuration of the iChip CO2128 via a local serial connection or via the Web. The iChipConfig utility also enables uploading an application’s website into the Secure iWiFi.
