ID1021 - front


 ID1021 - back

The ID1021 is a product from Iolia Datacom. Necoso is the exclusive dealer of Iolia products for Europe.


The ID1021 is a ready-to-use electronic module that can be integrated into an existing or new OEM product for quickly & easily realizing an internet interface for the product.

The ID1021 comes with an ethernet interface for connections to an intranet or internet. A 34-pole host interface is included that supports connections to all kinds of machines and devices.

The ID1021 internal software includes a full-fledged TCP/IP stack, FTP server, HTTP server and flash file system for storage of applications and webcontent.

Application fields

Typical OEM products for which the ID1021 module can be applied:

  • Climate control systems (heating & cooling)

  • Alarm systems

  • Vending and dispenser machines

  • Access control systems

  • Water management systems

  • Meteorological systems

  • Traffic control and management systems

  • Displays, signs and information systems

  • Energy metering and logging systems

  • Other telemetric and sensor systems

  • Protocol converters

Functions that can be realized with the ID1021 module:

  • Remote control/configuration of OEM product using web browser and FTP.

  • Communications with legacy OEM product with RS232, RS485 or TTL I/O interfaces. (protocol-conversion, ‘tunneling’ / ‘bridging’)

  • Remote servicing/upgrading of OEM product firmware/software/databases via the internet.

  • Remote data acquisition & logging, periodic retrieval of data using FTP.


There are many advantages as to the use of standard internet tools (web browser, FTP, Telnet) for remote control/service:

  • Works from any PC or workstation with access to the intranet or internet.

  • Remote monitoring/servicing/upgrading of OEM product via internet saves (traveling) time and money.

  • Avoiding MS-Windows application/device driver development. Many OEM manufactures feel like they caught in a rat-race - with every new version of the MS-Windows operating system they have to re-implement support for their equipment and adapt/rewrite their applications and device drivers. Using the ID1021 as a user interface this is no longer necessary. All that is needed are internet tools like web browser, FTP and Telnet. They are available for all (future/older) Windows versions and come for free with these operating systems. No PC software development required.

  • Support for non-Windows platforms like Apple, Linux, Sun Sparc and other Unix adepts. The ID1021 enlarges your potential market here. Most OEM manufacturers focus solely on the PC + Windows platform and neglect the other platforms. Usually because they don’t feel like the effort is worth the extra sales or don’t have the manpower, knowledge or support/development capacities to cover this relatively small but growing part of the market. With the ID1021 connectivity support for those platforms comes for free.

Availability options

Ready-to-use electronic module

The ID1021 is available as a ready-to-use electronic module. The fastest and easiest way to realize an internet interface for your OEM product.

Design-in package

The ID1021 technology is also available as a design-in package for integration on your own PCB. The design-in package consists of the ID1021 electronic schematics and the internal software for microcontroller that is on the ID1021. Reasons for preferring the design-package above the ready-to-use electronic module could be:

  • Saving space. Only one PCB instead of two.
  • Avoiding the connectors that are otherwise required between OEM PCB and ID1021.
  • Realizing the most economical solution by stripping all not used functionality/components.
  • Being independent as to customizing the software, hardware and/or mechanics.
  • Being independent as to the placing of the ID1021 external interfaces for network and host.
  • Being independent as to the ID1021 logistics.
