If you'd like to learn more about the DMX Protocol and uses for it, a very good web site is DMX512-Online run by Ujjal Kar. There is also an official FAQ at USITT. The complete specification for DMX512-A is contained in the ANSI E1.11-2008 standard which is available from the ANSI Web Store.

4201-B, stellarDMX DMX Controller and MIDI adapter

The 4201-B may be used in many different ways; we will assist you in getting your system set up and working. We’ll even write simple macro files for you if needed and ship units with macros, settings already loaded.

USB connections to Mac OS X and Linux systems now work with no adapters. We recommend USB connections whenever possible.

MIDI connections require our MIDI to RS-232 adapter which plugs in and is powered by the 4201-B. The MIDI adapter requires version 2.10 or later firmware in the 4201-B, other than that there is no special software needed.

The Model 4201-B may be controlled directly from any application or programming language on any machine that can talk to an RS-232 or MIDI port. The USB interface lets a Windows, OS-X, or Linux computer see the 4201-B as a normal RS-232 port, so no software changes are needed to use either the RS-232 port or the USB port on those systems.

The 4201-B allows setting a slower frame rate for use with low cost dimmers, if you have flickering problems try setting the frame rate to 20 (hex) using the “N” command.

MIDI capable Firmware, version 2.19 See the manual for the version you currently have for firmware update instructions.

New in this version, ^P adds soft patching for all 512 channels (works with or without stellarConsole). Also the ^D and ^F commands have changed slightly.

Also includes MIDI functions including fading to presets using the fade time stored by stellarConsole. Now you can set up your show with stellarConsole, copy it over to the 4201-B, and then run it with your MIDI sequencer. New macro command has been added to make it easier to step through presets and use all 8 User inputs with switches.

Utilities

stellarConsole, Version 1.7.5, a 24 channel control program for Windows, OS X, Linux. Recently added features are soft patching, naming faders, and moving faders in groups. This will also save your cues and fade times to non-volatile presets in the 4201-B for later access by a macro or MIDI command.

For Mac and Windows users who don't have a serial terminal program, Cool Term by Roger Meier works and is free. The only problem we've seen with this is in Windows if the serial port has been opened by another program such as HyperTerm, the computer will have to be rebooted before CoolTerm will open the port. Version below is 1.2.0.

For Linux systems we use GtkTerm.

4200, 4201, 4201a

These models have been replaced with the 4201-B. The 4201-B supports most of the functions of the 4200, 4201, and 4201a products but not all. Most importantly, the SmartLight™ Theater Lighting Software from Edgeview Software LLC does not currently support the “B” version, it has been discontinued. The free stellarConsole program above is the new replacement for it.
