M1 Control RS-232 ASCII String Protocol Page 40 of 68 Rev. 1.79 July 16, 2009
LL – Level/scene/state Status, 0 = OFF, 1 = ON, 2-99 =
light level percentage
00 – future use
CC – Checksum
Example: 0BPCA01000099 PLC change – A01, changed to OFF
Special: When an All_Lights_On, All_Lights_OFF, or All_Units_Off
command is transmitted the Unit Code will equal 00, and the Level (LL)
will be:
X10_ALL_UNITS_OFF = 01
X10_ALL_LIGHTS_ON = 02
X10_ALL_LIGHTS_OFF = 07
This transmission update option transmits the updated status whenever
it changes and is enabled by setting the location TRUE in the M1
Control Global Programming Location 39. Example: “Xmit Light Chgs–
ASCII” (Yes or No)
