10. Device Servers

11. What is a Device Server? • Serial-to-Ethernet Converter • RS232 or RS422 or RS485 serial signal converted to Fast Ethernet • First protocol conversion product from Transition • Allow you to network-enable and remotely manage legacy, serial-based devices such as: • Point-of-sale scanners and inventory bar code readers • Security systems, card access readers, HVAC systems, lighting • Freeway signs, traffic signals • Programmable logic controllers (PLCs), robots, conveyor systems • X-ray machines, CAT and MRI machines, patient monitoring devices

12. Device Server Benefits • Combine inherent benefits of data networking with asynchronous data transmission • Directly manage, access and control any device through the network in-building or through the internet from anywhere in the world • Benefits can be significant: • Immediate access to information from virtually any location • Improved flexibility in network design • Significant reduction in operational costs • Extend the life of legacy, serial-based devices – save money!! • Remote monitoring of equipment • Remote management of devices that previously could only be managed locally • Remote upgrades of serial devices

13. How does a Device Server work? • Encapsulates the serial bit stream into packets and transports it over the Ethernet network • Uses an external driver and software to “packetize” the data and • Can also perform the reverse function and restore the serial data to its original form • Remotely managed via an IP address • Three modes: • Direct IP mode (aka TCP/IP or UDP socket) • Virtual COM mode • Tunneling mode

14. Device Server Modes • Direct IP mode or COM Port • Direct IP connection • Communication via TCP/IP or UDP socket • Communication via COM Port • Requires external driver to convert COM port to TCP/IP socket • Also known as Virtual COM • Serial/IP® Redirector software – included

15. What is a Virtual COM port? • Allows the network connection (Ethernet port) of a computer to emulate a serial port (COM port) • Data is sent from application software to the host computer’s serial port • The external driver intercepts the data stream • Encapsulates the data into a TCP/IP packet • Re-directs the packet(s) to the Ethernet connection (NIC) Ethernet Port Data Data Data SerialPort Application Driver

16. Device Server Modes • Tunneling • Two Serial Devices connected directly to each other over Ethernet • The raw data in the IP packet will be transferred from and to serial port • No need to upgrade serial-only software platforms because serial data remains intact and is transmitted as if the host and serial device were connected directly via a serial cable

17. Ethernet-based Traditional Industrial Device Server – Needed? Ideal Migration Path

18. Industrial Device Server – More Likely Scenario

19. RS232/422/485 Device Server • Serial-to-Ethernet conversion • Network enable any legacy serial-based device • IP Remote Management • Telnet, Web browser or COM port • Six Different Device Server Modes • TCP Server/Client; UDP Server/Client • Device Server/Converter Only • SNMP Public and Private MIBs • Remote TFTP Upgrade • Ideal for SCADA RTU devices • RS232/422/485 to 10/100BT SDSFE3110-120
