The HelloDevice Super Series is a serial-Ethernet convertor with dynamic DNS and PPPoE protocol support to manage serial devices from remote areas.
The HelloDevice Super Series from Sena Technologies is a serial-Ethernet convertor with dynamic DNS and PPPoE protocol support to manage serial devices from remote areas.
Applications include: industrial automation; network management; retail/point of sale; remote metering; remote display; building automation; security/access control systems; general data acquisition application; and medical automation.
The SS100 supports RS232/422/485 serial communication, allowing virtually any asynchronous serial device to be accessed over a network via its DB9 serial port, and handles serial data transfer rate up to 230Kbit/s.
As for the Internet connectivity, the SS100 supports open network protocols such as TCP/IP, UDP and PPPoE (PPP-over-Ethernet), allowing serial devices to be accessed over a DSL-based broadband network or a conventional LAN environment through the 10/100Mbit/s Ethernet interface.
The SS100 provides the full-featured management functions such as status monitor, remote reset, error log monitor and firmware upgrade using Telnet, serial console port or web browser under the password protection support.
In addition, the SS100 provides IP address filtering function to protect unintentional data streams to be transmitted to the serial device, and public key cryptography based SSL data encryption to promise secure data communication.
The SS100 also has the SNMP agent supporting SNMP v1 and v2 protocols, and dynamic DNS client for updating user's hostname account offered by various service providers.
Benefits include: cost-reduction in system development due to using low-cost, industry-standard Ethernet technologies; labour cost reduction and improved efficiency due to remote management; easier operation environment using various IT technologies such as Internet, web and database; cost-reduction due to TCP/IP-oriented simplified network hierarchy; and it is easy to establish a company ERP (enterprise resource planning) system by connecting TCP/IP-based business system with manufacturing system.
