SSL-equipped serial-Ethernet convertor
POSLink from Sena Technologies is an SSL-equipped serial-Ethernet convertor for leased-line based credit card payment terminals connected to broadband Internet.
The TCP/UDP multicasting feature is provided for those applications, which involve a PC host sending messages to many serial devices simultaneously.
For example, the STS Series can transmit a message to several signboard devices, and/or send control information to many PLCs simultaneously.
Furthermore, 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, the 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 management is provided with dial-in access through a modem connection, In-band management is with 10/100Base-TX Ethernet network.
Dynamic DNS protocol facilitates a static host name to the STS Series.
Featuring a PCMCIA slot for enhanced functionality, the STS Series can be expanded using a LAN or wireless LAN card to access another network, a PSTN/CDMA card for phone-line connection, or a Flash memory card for storage.
Furthermore, serial device data can be stored in internal memory, on 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 a versatile 1U solution for serial device integration in process control based applications.
