The DMX-Dongle is supplied with both Windows and DOS user control software, and free development software (SDK) for both platforms. The Dongle is supplied with Windows 32 Bit VXD, a 16 Bit DLL, and a DOS 'C' Library. The DLL is written in Delphi Pascal and the DOS library is compatible with Borland TC & BC. The Libraries contain all the functions required to construct sophisticated DMX512 applications.

Features

  • Simultaneous transmit and receive
  • DMX512 transmission of 512 channel data
  • Receive 512 channels at 8-bit resolution and full bandwidth
  • DMX512 receive with programmable base address
  • Programmable Merge and Loop Through
  • Programmable transmit Break, Mark after Break and Header Code
  • Programmable receive Header Code
  • Analysis of receive errors
  • Receive Break and Mark after Break timing analysis
  • Multiple oscilloscope trigger outputs

Supplied with

The DMX-Dongle is the perfect tool for any manufacturer, hire company or venue using the DMX512 protocol. A Developer's guide is also available for those wishing to incorporate the Dongle into their own software. An extensive software package is included with the Dongle, as described below.

Windows User Software:

The Windows software is called DMX-Workshop. This provides access to all the power of the DMX-Dongle II and is also compatible with Artistic Licence ArtNet Ethernet products. DMX-Workshop contains applications which can be accessed from a small task bar. All DMX512 header codes can be received.

DMX-Workshop application

  • The Transmit application provides a level fader which can be used to control a single channel, a group of channels or set the level for two automatic modes: 'Dynamic' and 'Walk'.
  • The MIDI application operates in conjunction with your PC's sound card. It displays real time received MIDI data and is invaluable for debugging.
  • The Receive application features a level display for all 512 channels.
  • The detail screen provides all the protocol timing data along with a log of frames received and any errors detected.
  • DMX-Workshop also provides an Oscilloscope display of channels levels, full screen mimic and MIDI data analysis.
  • Display and analysis of new DMX512-A features such as Text Packets and System Information Packets is also provided.

Windows Development Software:

A Windows DLL (32 bit) is supplied free of charge with the DMX-Dongle. The DLL is compatible with Windows 95 / 98 / ME / 2000 / NT & XP. Example applications for Borland C++ Builder and Microsoft Visual C are also included.

DOS User Software:

DMX-Analysis provides control for both Transmit & Receive. The Transmit section allows up to 50 DMX memories to be programmed and stored on disc. Editing can be performed in decimal, hexadecimal or binary. The Receive section allows any 64 of the 512 possible channels to be displayed on screen. Non-Zero levels are displayed in colour to enhance readability. The display format may be selected to decimal, hexadecimal or binary.

The detail screen provides all the protocol timing and error data including: Refresh rate and cycle time, Number of channels in frame, Break time, Mark after Break time, Number of frames received, Number of non matching start codes received, Number of overrun errors received and Number of framing errors received.

Full analysis of the new DMX512-A System Information Packet is also provided.

DOS development software:

A complete C development library is supplied free of charge with the DMX-Dongle. The C-Library is DOS based and optimised for the Borland series of compilers. Full source code is included and the library is royalty free.

Applications:

The following existing software products support the DMX-Dongle:

  • Grand-Master Flash! (Artistic Licence)
  • Grand-Master (Artistic Licence)
  • Capture CAD & visualiser (Capture Sweden)
  • SoftStage (Soft++)
  • ShowMan (Richmond Sound Design)
