  3. Overview (1) • Linux-based Open platform (kernel 2.4.2) • Supports 1/2/4/8 serial port (RS232/422/485) • 1 PCMCIA slot • ATA flash memory, LAN/WLAN, PSTN/CDMA Modem • Flexible host mode mode • TCP/UDP single/multi-session support • Primary/Secondary host support • Powerful Security • Industry-standard encryption support • SSL, TLS • Encryption algorithm support • 3DES, RC4 • Flexible customization • Linux CLI with development environment • Source file add/modify/compile/link in 1MB user space • Web customization

  4. Overview (2) Connections Device Remote Host Host (SS) Any device with serial interface • RS-232 • RS-422 • RS-485 • LAN • Wireless (802.11b) • PSTN • Mobile (CDMA)

  5. Functions & Features • Operation modes • Data logging • Event handling • Security • PC Card support • Customization

  6. Operation modes (1) box IP Addressing SS • 210.205.197.172 or ss.sena.com Dynamic DNS ... Port #1 Port #2 7001 7002 TCP/UDP port • When access the box • Telnet 210.205.197.172 or ss.sena.com • http://210.205.197.172 or ss.sena.com • When access the serial port • 210.205.197.172, 7001 or • ss.sena.com, 7001

  7. Operation modes (2) Remote host • TCP/UDP Various operation modes device TCP/UDP socket Remote host • modem emulation DTE TCP socket • Dial-in/out mode Remote host modem TCP socket modem DTE

  8. Operation mode (3) • Multiple remote hosts Up to 16 Remote destinations • Total 32 connections per serial port • Total 16 outgoing connections allowed • If connection to the primary fails, SS tries to connect the secondary remote host. (TCP mode) • Most suitable for multiple remote device monitoring application (Bi-directional) Secondary (back up to the primary) Primary Device Secondary Primary

  9. Security • Serial data encryption • SSL v2 & v3, TLS • Supports encrypted key file • Option to authenticate clients using the client's certificate in server mode • Option to configure chain depth • Option to compare certificate common name with host • 3DES, RC4 • Static Key encryption • Secured Web interface • HTTPS • IP filtering • serial port based IP filtering • box based IP filtering • Secured file uploading • SCP
