The Silex SD-330AC-1402 is a FIPS 140-2 certified wireless / wired LAN Serial Device Server as well as an Ethernet to Wi-Fi Bridge which securely connects devices equipped with the RS-232C serial interfaces and/or the Ethernet into any network eliminating the need for wired connection between the devices and the computers. Medical devices, printers, scanners or virtually any other device with a serial port or an Ethernet port can now be enabled with secure and robust LAN network capability.
Security | FIPS 140-2 cryptographic operation
SD-330AC-1402 enables medical devices, printers, scanners or virtually any other device with a serial port or an Ethernet port to secure the transport of personal confidential data and ensure the integrity of electronic data over a Wi-Fi wireless network as per FIPS 140-2 requirements.
In FIPS 140-2 mode, FIPS 140-2 certified WLAN authentication WPA2-PSK can be used, and WLAN communication is encrypted by AES CCMP. When customers use applications such as TCP port serial services, eCable client service and so on, the end-to-end application security is established by TLS encryption.
- Wi-Fi connection security by WPA2-PSK AES CCMP encryption.
- Secure firmware update over HTTPS
- Firmware signature check
- Secure connection to unit web GUI over HTTPS
- TCP port serial servicesin TLS encrypted mode
- eCable clientservice in TLS encrypted mode
