  3. Device Control Application Real COM Mode Confidential

  4. Real COM-With Native COM port driver & Real/Fixed TTY driver Selection Principle • COM/TTY port application • On Hostdriver will establish the connection • On NPort • "Listen" for connection Ethernet COM3 COM4…… COM N • Real COM driver: • Win9x/NT • Win2K/WinXP/2003/Vista/7/2008 x86 • WinXP/2003/Vista/7/2008 x64 • Real TTY driver: • Linux 2.4/2.6 kernel x86 • Linux 2.4/2.6 kernel x64 • Fixed TTY driver: • SCO Unix, SCO OpenServer 5 & 6, Unixware7, Solaris 10 x86/Sparc, SVR4.2, QNX4.25, QNX6, FreeBSD 5.x & 6, AIX 5.x

  5. Real COM multi-connection application:Multiple Hosts using COM together Ethernet Max. Connection2G NPort: 43G NPort/NPort A:8 • Tips: • 1. Up to 4 hosts using COM together • 2. First in first service, if NPort receive host’s data • 3. Multicast to 4 hosts, if NPort receive serial data • 4. Advanced • Allow driver control • Ignore jammed IP • Command by command NPort 6000 COMn io Server

  6. Device Control Application Reverse Real COM Mode Confidential

  7. Selection Principle Introduction • COM port application • On Hostavailable to be connected • On NPort • "actively" connects with the Host • when power on • Real COM Client Server Establish Connection (Driver) (Firmware) CellularNetwork • ReverseReal COM Server Client Establish Connection (Driver) (Firmware) Confidential

  8. Installation:Step1. Set Reverse Real COM Listening Port Confidential • In NPort Windows Driver Manager • Configuration -> Reverse Real COM • Set Listening Data port & Command port.

  9. Step2. Select OP mode Confidential Login Web console and select Application & Mode

  10. Step3. Specify the Host IP & Listening Port • Specify the PC's IP & TCP listen port • Define NPort "local" data & command port • For some firewall or NAT management issue Confidential

  11. Step4. Mapping COM port • NPort Windows Driver Manager • Add NPort -> Input Manually -> Reverse Real COM Confidential

  12. Device Control Application RFC2217 Mode Confidential

  13. What is RFC2217 mode Selection Principle • COM/TTY port application • On Hostusing RFC2217 COM driver • Similar to Real COM mode • COM port control protocol • An extension of the Telnet protocol :Allows applications to set parameters of remote serial ports (baud rate, flow control, etc.) and detect line signal changes • Can receive and transmit data • Drivers based on RFC2217 may be developed for different devices Confidential

  14. CRC CRC IP Header IP Header TCP Header TCP Header Data Data IP Header TCP Header I/O Control CRC IP Header TCP Header I/O Control CRC RFC2217 vs.Real COM mode TCP Data Port Real COM Mode <IP Address> : 950/966 TCP Command Port Host NPort 6000 RFC2217 Host COM Port Control Protocol <IP Address> : 4001 NPort 6000 Confidential RFC2217 transfers data and serial command via the same TCP port Real COM Mode has more efficient performance than RFC2217

  15. CRC CRC IP Header IP Header TCP Header TCP Header Data Data IP Header TCP Header I/O Control CRC RFC2217 vs. TCP Server mode TCP Server Mode Host TCP Data Port NPort 6000 <IP Address> : 4001 RFC2217 Host COM Port Control Protocol <IP Address> : 4001 NPort 6000 Confidential TCP server mode only can receive and transmit data via TCP port 4001

  16. Third Party RFC2217 Driver —Serial Port Redirector & Serial/IP Redirector • Serial/IP have verified working with NPort 6000 • How to use:1. Set RFC2217 mode in NPort 6000 console2. install RFC-2217 driver3. map COM port in driver Serial/IP Redirectorhttp://www.tacticalsoftware.com Serial Port Redirector http://www.serial-port-redirector.com Confidential
