12 inputs for contacts, 4 outputs and a RS-232/485 serial port connected to the Ethernet over IP. I/O Controller 1204 is a terminal server (serial line) with added binary inputs (for contacts) and outputs. M2M communication over TCP/IP using a Telnet-type NVT protocol. The device actively informs about changes at inputs, and supports a TCP Client/Server mode.
Serial port, inputs for contacts and outputs are controlled over a TCP/IP connection using a TELNET-like (RFC2217) M2M protocol. The protocol is compatible with NVT, the extension to 12 inputs is described in the manual. The Hercules SW terminal can be used for testing (supports inputs and outputs).
* I/O Controller actively notifies about state changes at inputs; if a TCP connection is not active, the device establishes it as a TCP client.
* The serial port can be connected to via a virtual serial port (e.g. COM27) on your networked PC. The HW VSP application for Windows is supplied free of charge.
* Control the product from your own application in minutes.
Make your work easier with many examples for various programming languages in the HWg SDK (Borland C++ Builder, MS Visual C, VB, Delphi, C#, PHP, JAVA).
Basic features
* RS-232/485 serial port
* 12 binary inputs for contacts
* 4 built-in double-throw relays
* Modes of operation:
o TCP Server
o TCP Client/Server
o UDP (without I/O)
* Virtual serial port driver for Windows = easily get e.g. COM 5 on your PC
o The "HW VSP Multi virtual serial port supports up to 100 serial ports on a single PC.
* Access security can be enhanced with 128-bit authentication (TEA), or by restricting access to the device to a defined IP address range. |

Applications
* Link up to twelve buttons with a SW application.
* Easily connect a serial printer output to an IP network (LAN / WAN).
* Control a horn or an alarm signal using the outputs that can be boosted with external relays.

M2M communication
* TCP/IP Server [Client -> Server]
I/O Controller, as a TCP server, listens for incoming TCP connections from a computer (a PC or a server). When the connection is established, data in the internal buffer are transmitted, and then bidirectional communication can take place, similarly to a common "terminal server".
Binary inputs and outputs can be controlled with a M2M protocol that uses an extension of RFC2217 (NVT support must be enabled).
* TCP/IP Client/Server [Server <- Client]
I/O Controller has received some data into its internal buffer from the serial port (or has detected a change at the binary inputs) and attempts to send it to the server. The unit tries to establish a connection to the specified outgoing IP address and port. If unsuccessful, it waits for about one second in the TCP server mode and then tries to establish the connection again.
Binary inputs and outputs can be controlled with a M2M protocol that uses an extension of RFC2217 (NVT support must be enabled and the TCP connection must be established).
* UDP/IP
Data are sent as UDP packets, without delivery acknowledgement.
In the UDP mode, the device uses a sophisticated "packetiser" that allows you to specify broad conditions about what should be sent from the serial line to the Ethernet, what should not, and when.
Binary inputs and outputs cannot be controlled in the UDP mode.
* VSP (Virtual serial port)
The HW VSP software, when installed on a PC with Windows, creates a virtual serial port (e.g. COM7), and the serial port at the I/O Controller then works as a physical port of your PC.
Binary inputs and outputs can be controlled from HW VSP using the "Binary I/O" tab, as long as NVT support is enabled for both the HW VSP software and the I/O Controller unit
