| Sena Technologies Introduces Wireless Terminal Server For Device Networking |
 The STS Series is a linux-based Secure Terminal Server with PCMCIA interface to manage multiple serial devices over the network Sena Technologies introduces the Linux-based wireless Terminal server "STS Series", to manage the RS232/422/485 based industrial equipment, retail and point-of-sale terminals, modems, servers, or any serial device over the network with advanced features such as TCP/UDP multicasting, Security, PCMCIA, and Data logging. The STS Series supports an enhancement transmission method "TCP/UDP multicasting", which automatically broadcasts same serial data to 32 remote destinations simultaneously. This feature is very useful in applications where user needs to transmit a message to several display signboard devices simultaneously; send control information to many PLCs simultaneously. Moreover, flow control options such as Hardware RTS/CTS, and Software Xon/Xoff can control the amount of serial data to be transmitted between STS Series and serial devices. For secure data communication between a serial device and Remote PC hosts, SSLv3, TLSv1, RC4 encryption and IP filtering features are provided. In addition to security, Terminal Server provides the benefit of both in-band and out-of-band management, ensuring that connected serial devices are always accessible, even when the network fails. Out-of-band is provided with dial-in access through a modem connection, In-band is with 10/100 Base-TX Ethernet network, and Dynamic DNS protocol facilitates a static host name to the STS Series. Featuring a PCMCIA slot for enhanced functionality, the STS series supports LAN/Wireless LAN card to access another network, PSTN/CDMA card for phone-line connection, and Flash Memory card for storage. Further more, Serial device data can be stored in internal memory (RAM), a syslog server, or to an NFS server. Ready to rack mount in 8 or 16 port formats and fully-managed via web, console or SNMP, the STS series is the 1U solution for serial device integration in process control based applications. www.sena.com |
