2. Maximum number of steps in any sequence is 31.
3. Total number of steps for all sequences is 128.
4. It is recommended that all sequences be listed and named, for future
reference.
(e. g. Sequence #4 is XYZ Presentation; Sequence #1 is Product Demo; etc.)
Response: CMD14, Erc, Cks1, Cks2, EOT
Possible Ercs: C5 = Out of memory space;
C6 = Not enough space for next sequence step (sequence
incomplete)
CMD15 (3Fh) — Request a Stored Sequence
The Host asks the Matrix to send the information contained in a specific
Sequence. This would have the same format as shown for CMD14. This
command could be used to edit a sequence and save it again, or to edit and
save it as a new Sequence.
Format: CMD15, Seq#, Cks1, Cks2, EOT
Response: CMD15, Erc, Seq#, {see CMD14}, Cks1, Cks2, EOT
CMD16 (40h) — Operate Sequence #
The Host tells the Matrix to perform a specified operation regarding previously
stored sequences. See SqOp list below.
Format: CMD16, SqOp., Seq#, Cks1, Cks2, EOT
Where: Seq#
Sequence number to be operated on (bits 4-0)
Sequence 1 - 31 = 81h - 9Fh)
and:
SqOp
Operation code as follows:
80h
Start a specific sequence (SEQ#)
81h*
Stop (interrupt) sequence that is now running.
82h*
Resume running the sequence that was stopped.
83h
Delete a specific sequence (SEQ#)
E0-FFh
Copy Seq# to the sequence # defined by bits 4-0.
* Set Seq# to 80h
Response: CMD16, Erc, Cks1, Cks2, EOT
Possible Ercs: C7, C8, C9, CA, CB = sequence not found (depending on SqOp)
CC = Out of memory space
CMD17 (41h) — Request a List of Presets
The Host asks the Matrix to send a list of all defined presets.
Format: CMD17, Cks1, Cks2, EOT
Example: 41h, 80h, C1h, 04h
Response: CMD17, Erc, (PresetX, ...PresetY, CR), Cks1, Cks2, EOT
Where: Preset is the number of a saved preset. All saved preset numbers will be
sent in numeric order. (Preset #1 = 81h) If no presets are stored, this
byte will be 80h.
