This firmware personality allows anything with a standard serial port to generate DMX scenes, looks and fades.
Data is accepted a standard 9600 8N1 baud rate. A universe of DMX-512 information is sent out the back door, based on a simple human-readable ASCII command set.
All commands are followed by a carriage return (noted by [cr] below). Note that the 8-bit DMX channel value scale is accessed directly – its range is [0 255] – rather than on a 0-100% scale.
Set channel XXX (a three digit decimal number in the range [1 512] to value YYY (a three digit decimal number in the range of [0 255]). Fade time is instant.
F012:234[cr] Set DMX channel 012 to 234
As above, except that a three digit fade time ZZZ is included. This time is measured in tenths of a second. Thus, fades of up to 99.9 seconds can be described.
F511:128t025[cr] Fade channel 511 to 50% over 2.5 seconds
Set a group of channels to a specific level, instantly or with a calculated fade:
F020-100:200t040[cr] Fade channels 20-100 to 200 over 4 seconds.
Finally, the lowly semicolon – ‘;’ – can be used to chain commands together, to build crossfades. Note that only one time value is used per command line, and it’s included at the end of the series:
Fade channels AAA-BBB to zero, set 124 to full, fade 128-150 to 50% over 4.5 seconds.
Also, the system reports ‘OK’ when valid command is received and ‘Done’ when the dimming engine has finished setting the new levels.
