DC-09 UDP Analyzer Tool

UDP analyzer icon 256x256

This PC application accepts UDP messages from a network, validates checksums and returns ACK or NAK to the originating communicator as appropriate.  Incoming messages are parsed, showing individual fields and HEX values for messages.  It is intended to assist with implementing a product that will send DC-09 protocol.


  • UDP packet support
  • receives DC-09 messages from an IP digital communicator
  • validates DC-07 CRC in messages, shows both expected and observed CRC
  • returns ACK or NAK message to communicator as appropriate
  • displays individual message elements, including: account number, account prefix, receiver number,
  • message data, time stamp
  • displays IP address of transmitter
  • logs all activity to a text file
  • message shown in ASCII, parsed ASCII and hex formats
  • details of ACK or NAK message are shown
  • IP port is configurable
  • 128 bit encryption is included


  • saves capital expense – you don’t need to purchase or upgrade a receiver
  • reduces testing time by showing elements of each message received, rather than the receiver’s processed output
  • supports release testing – you can deploy a single license with multiple people within your organization
  • reduces rework by providing a stable reference implementation of the DC-09 standard
