CMD18 (42h) — Set Program
The Host tells the Matrix to start a specific event (preset or sequence) at a
specific time, on a specific date. Matrix power will be turned On at that time. This
is called a program. Only one program can exist in a Matrix 200 at one time.
Format: CMD18, PrgEvnt, Num, Yr, Mo, Dy, Hr, Min, Sec, Cks1, Cks2, EOT
Where: PrgEvnt the program event which will be started (triggered).
80h a Preset will be started
81h a Sequence will be started
Num the event (preset or sequence) number to be started.
(for Yr, Mo, Dy, Hr, Min, Sec see clock - CMD22)
Response: CMD18, Erc, Cks1, Cks2, EOT
Possible Ercs: CD = Clock not set
CE = Sequence file not found
CF = Preset file not found
D0 = Too late; run time has passed
CMD19 (43h) — Request the Current Program
The Host requests the characteristics of the pending program. There can only be
one program in the Matrix at one time, therefore, no specific information is
needed.
Format: CMD19, Cks1, Cks2, EOT
Example: 43h, 80h, C3h, 04h
Response: CMD19, Erc, PrgEvnt, Num, Yr, Mo, Dy, Hr, Min, Sec, Cks1, Cks2,
EOT
CMD20 (44h) — Operate Program
The Host specifies action directed to programs.
Format: CMD20, PrgOp, PrgEvnt, Num, Cks1, Cks2, EOT
Where: PrgOp Specifies the action to be executed.
80h Delete the program
81-FFh reserved, PrgEvnt and Num are not currently used.
Response: CMD20, Erc, Cks1, Cks2, EOT
Possible Ercs: D1 = No program found
CMD22 (46h) — Set Clock
The Host sends the date and time for the Matrix 200 to set the internal calendar
and clock.
Format: CMD22, Yr, Mo, Day, Hr, Min, Sec, Cks1, Cks2, EOT
Range: Yr 00-99 Mo 01-12
Day 01-31 Hr 00-23
Min 00-59 Sec 00-59
Response: CMD22, Erc, Cks1, Cks2, EOT
