Releu IP HWg-ER02a: releu 230V & RS-232 prin Telnet

Warning: Product was replaced by IP Relay HWg-ER02b

Releu IP HWg-ER02a: Doua relee 230V si un port serial RS-232/485 controlat prin Ethernet (Telnet)

Note: Shorted version - full details in english version.

Doua relee de iesire capabile sa comute 230 V, si un port serial la distanta prin IP. Versiune industriala, montabila in sina DIN.

Portul serial este accesibil prin protocolul Telnet. Alternativ, acesta poate fi redirectionat catre un port serial virtual in Windows (de exemplu COM 27).

Intr-o aplicatie tipica, releul IP este folosit pentru a deschide de la distanta o poarta prin LAN (iesire releu 230V) si pentru a conecta un cititor de carduri RFID (RS-232).

  • Utilitar comanda HWg IPRC: Linie de comanda pentru control la distanta a iesirilor (Windows si Linux)
  • Software HW VSP: Port serial virtual pentru Windows (NT service). Suporta pina la 64 porturi seriale remote.
  

Typical applications

Usage examples

  • Remote monitoring of  IP camera system's failure
  • Remote control of the network configuration
  • Remote control and restarting of micowawe connections.
  • Remote devices control (ventilation, door opening..)
 

One built-in serial port can be used for remote access using RS-232 console, but it also can be used as a virtual serial port (for example "COM 8") using the HW Virtual Serial Port driver.

You can order the IP Relay in the DIN molding version, or a modification with 8 inputs and 8 outputs (the I/O Controller). If you are not sure wheather the IP Relay can be used in your application, please contact us...

Application note

  • AN21 – Controlling of IP Relay using program NetCat
    IP Relay contains except RS-232 serial port also another two relay, which switching on/off can be controlled over Ethernet (TCP/IP). This application note describe how to control ethernet i/o relays from the Windows command line sending right sequence using program NetCat.
 
 

M2M (Machine to Machine) Communication protocol

remote control, normally open, normally closed, terminal server, ethernet i/o relay, IP Relay, web based relayThe built-in relays are controled using NVT commands. This is a 7-byte sequence, which is sent to the opened TCP/IP connection and if accepted, it is confirmed with a similar 7-byte sequence sent back. This TCP connection is similar to the TP connection to the RS-232 port, but when using the NVT (which is a standard TELNET) the data from serial port are not interrupted when sending the commands. You can read more about NVT and our RFC2217 compatible extension on the Network Virtual Terminal page. Detailed list of relay's controling commands you can find in product manual.

  • HW Virtual Serial Port
    remote control, relay switch, normally open, normally closed, terminal serverVirtual serial port driver for windows is a software tool for adding a virtual COM port to your windows system. All the data from this port is then redirected to another HW interface.

    You can control the relays using the "Binary I/O" tab.
    • Unlimited, free Virtual Serial Port for any TCP/IP device.
    • Designed for Windows 2000, XP Vista, 200 server, 2003 server.
    • If the device supports RFC 2217 (NVT), you can setup all the serial port parameters (speed, parity, stop bits).
    • The driver works as a "TCP client", but it can be also used in "TCP server" mode.
    • Logging all the communication into a file, to make debugging easier.
    • You can create more virtual serial ports on one system using command line parameters
    • The software can be run o a windows startup and hidden to the system tray.
