DTM-3224 - Quad ASI To IP Conversion Module  


Quad ASI To IP Conversion Module

The DTM-3224 is a highly-integrated and cost-effective OEM module for converting four ASI transport streams to IP. The next-generation architecture of this device has support for IPv6 and for IGMP v3, enabling source-specific multicast.

  • High-density variant of the DTM-3200 for converting 4 transport streams from ASI to IP.
  • By processing packets entirely in hardware, the input-to-output latency is kept low (<1ms) and no unnecessary jitter is introduced.
  • IP output can be multicast over a network to potentially many receivers. IPv6 and source-specific multicast (SSM) are supported.


  • Use the DTM-3224 as an "I/O extender" for adding ASI inputs to transport-stream processing equipment (e.g. multiplexers) that receive all streams over a network port.
  • Multi-channel ASI to IP gateways.
  • Feed ASI signals to a PC application via the PC's standard network port.

Control Software

The DTM-3224 can be controlled through one of the available serial interfaces. Settings applied are stored in nonvolatile memory on the unit, and automatically reloaded after a power cycle. It is not possible to configure the device via the Ethernet interface.

DekTec provides the following software for controlling the DTM-3224:

  • Dtm3224Util - Windows tool to view status, to control settings and to upload firmware. This tool is convenient for initial configuration and for experimentation with the DTM-3224.
  • DtmHandler - A set of C functions, also useable from C++, implementing a protocol handler. With these functions, controlling the DTM-3224 from your application becomes really easy. Full source code is available, so that you can use the protocol handler functions with any compiler.
  • DtmCmd - Windows/Linux command line tool for controlling the DTM-3224. DtmCmd is an example of using the DtmHandler functions.
