1. Introduction
1.1. Overview
The STS Series is a secure terminal server (or device server) that makes your legacy serial devices
manageable by industry-standard Ethernet network. Based on open network protocols such as TCP/IP
and UDP, it gives you ultimate flexibility to your serial devices. With PPPoE (PPP-over-Ethernet)
connection feature of the STS Series, the RS232 serial devices could be managed over DSL-based
broadband network.
With the rich broadband network connectivity protocols such as DHCP, PPPoE and Dynamic DNS,
you could easily manage the legacy serial devices over broadband Internet by using DSL or cable
modem connection. The built-in Dynamic DNS protocol of the STS Series enables you to access the
serial devices with their domain names.
The STS Series also provides you with full-featured system management functionality of system
status display, firmware upgrade, remote reset and system log display by using various ways such as
telnet, serial console port or web.
You could easily configure and administrate the STS Series, with the full-featured management
functions of status monitor, remote reset, error log monitor and firmware upgrade by using Telnet and
serial console port under the password protection support.
For critical applications of secure data communication, the STS Series supports SSLv2, SSLv3 and
TLSv1 for data encryption. In addition, IP address filtering function is provided for protecting
unintentional data streams to be transmitted to the STS Series.
Typical application areas of the STS Series are:
- Industrial automation
- Network management
- Retail/Point of sale
- Remote metering
- Remote display
- Building automation
- Security/Access control systems
- General data acquisition application
- Medical application
The STS Series gives you ideal remote management capability of control, monitoring, diagnosis and
data gathering over RS232 serial devices.
