DMX Commands
The following sections describe the DMX-specific commands that are available on the
SmartMotor. The commands are organized by function.
Select DMX Channels
The following commands are used to select the DMX channels:
NOTE:
If the input is out of range, these commands will be ignored and issue a
command error. They do not retain any settings between power cycles.
l
COMCTL(1,value)
Set base channel [value] (1 through 512); default is 1 at power-up.
l
COMCTL(2,value)
Set number of channels [value] to read starting with base channel
(1 through 102); default is 1 at power-up.
l
COMCTL(3,value)
Sync on channel, where value is the channel number 1-512; default
is 512 at power-up. User bit 2 is set when that channel is received. Therefore, a full 512
channel packet will set this bit at the end of the packet.
l
COMCTL(4,value)
Allows for the selection of the aw[ ] register where the DMX data
begins loading; default is 0 at power-up. For example, COMCTL(4,10) will start loading
DMX data at aw[10].
