Alternate Start Codes

ALTERNATE START CODES

The Alternate START Code Database is a record of all the known Alternate START Codes used in communications conforming to the USITT DMX512/1990 and ANSI E1.11-2004 standards. Please note that until ANSI E1.11-2004 was published, there was no formal procedure for registering Alternate START Codes, only an informal procedure of notifying one of the original authors of USITT DMX512, who kept a list of the Codes. Thus, some manufacturers implemented Alternate START Codes in products without assurance that the START Codes were not already being used by other manufacturers and without advertising the START Codes so that other manufacturers would not later adopt the same code for a different message type. ANSI E1.11 formalizes the Alternate START Code registration procedure. The publication of this database makes the known Alternate START Codes and their purposes available to the public.

Any manufacturer wishing to register a new Alternate START Code may do so by sending information about the code to ESTA's Technical Standards Manager at . This information must include the Code's value, a brief description of its purpose, the company's name and address, and contact details for a person to whom questions about the Alternate START Code may be addressed. Contact details would include telephone and fax numbers, and email address.

Since the number of Alternate START Codes is limited to 255 possible values and many of these are already assigned or in use, only one Alternate START Code per manufacturer will be assigned from now on. Manufacturers are encouraged to obtain a two-byte Manufacturer's ID and to use it with Alternate START Code 91h to create proprietary messages.

Below is a listing of all registered and known DMX512, DMX512/1990, and ANSI E1.11-2004 Alternate START Codes.

optimized for safe and secure motor control, embedded with

this alternate data type on the DMX network, while keeping

packets as short as possible. Y

26 1Ah Integrated

Theatre, Inc. Well, I'm still convinced that we need to develop some (more)

uses for the 2nd pair, and I have several ideas in mind. The

ASC data would be used on the first pair in conjunction with the

2nd pair data. That way in systems that only had the 1st pair

wired some functionality could still be had, but more could be

gained by using both pairs.

My thought is to develop these things as open standards,

and if there is enough interest turn them over to ESTA for

development into a consensus standard. Y

27 1Bh Espace Concept The purpose is to toggle inner program of the receiver.

If the Start code is 0, the machine answers with Program 1.

If the Start code is 27, the machine answers with Program 2.

Rest of the DMX trame would remain exactly the same as in

USITT description. The purpose for us is to control different

types of machines with the same DMX values (Program 2)

using a switch box sending Start Code 27 and predetermined

DMX values. The program run by Start Code 0 would be

adapted to a fader control. Y

Theatre Controls Alternate start code DD is for use in transmitting per channel

priority for use in merging streams in multi-source DMX

applications. Priorities will range from 0 at the low end, which

means do not use the data in the corresponding slot, to 200,

which means use this data over any slot data supplied with a

priority between 0 and 199. Values above 200 are reserved

for future use. Y
