  1. SENA Secure Terminal Server, STS Series One-Stop Solution in Device Networking March, 2004 March, 2002

  2. Table of Contents • Overview • Functions & Features • Operation modes • Security • PC Card support • Event handling • Data logging

  3. Overview (1) • Linux-based Open platform (kernel 2.4.2) • Supports 8/16 serial port (RS232) • 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

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

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

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

  10. PC Card support http://www.sena.com/products/by_name/sts/pc_card/

  11. Event handling • Event filtering and notification procedure STS Device SNMP trap reaction E-mail data stream message packaging filter (SMS)

  12. Data logging Data logging locations SYSLOG server Ethernet NFS server STS internal Memory (RAM) Storage PCMCIA card
