XB-DMX512 DMX512 Interface
Patch Buffer Send_Commands
The patch buffer Send_Commands determine which if any DMX inputs modify the patch buffer. The
following table lists the Patch Buffer Send_Commands.
Direct Control Buffer Send_Commands
Command Description
DS
Stores a snapshot of all DMX output
channels.
This is the final output of the DMX512 box and is also affected by the
values in the Patch and Group Buffers.
Note that this command stores all DMX512 channels, even channels
that are not currently being transmitted through the use of the ‘ML’
command (refer to theMiscellaneous Send_Commands section on
page 21).
Syntax:
"'DS<preset number>'"
Variable:
preset number = 1-72
Examples:
SEND_COMMAND DMX,'DS1'
Stores preset 1.
SEND_COMMAND DMX,'DS72'
Stores preset 72 (there is a max of 72 presets with standard memory).
To exclude (undefine) channels, the Group Buffer Commands must
be used, NOT the Direct Buffer Commands.
DZ
Sends all outputs in the Direct Control
buffer immediately to zero.
Clears all values in the Direct Control Buffer to zero.
Syntax:
"'DZ'"
Stops all 'DR' ramps.
Patch Buffer Send_Commands
Command Description
PA
Patches inputs 1-512 in a one-to-one
relationship with outputs 1-512.
This is typically the second step (after clearing the memory), when
setting up the DMX512 box to sit between a lighting console and its
dimmers. The outputs immediately change to reflect the inputs and
will track any input changes.
Syntax:
"'PA'"
Globally connects all DMX inputs to DMX outputs in a 1 to 1
relationship.
