REGISTER MAP
Data can be read using the Read Holding Registers command. A memory map de-
tailing all useful locations is listed below:
Notes: [1] See table in next section for possible values in this register. [2] A value
0-255 will result in zero brightness (0) to maximum brightness (255). Any value lar-
ger than 255 is internally set to 255. [3] This register reflects the status of the input
pins. The pins do not control anything, but can be used to read the status of exter-
nal equipment.
Pin numbers
The input status register reflects the value of the input pins. Toggling these pins
while the unit is configured as a Modbus device does not affect the operating
behavior.
Light effect types
The input status register reflects the value of the input pins. Toggling these pins
while the unit is configured as a Modbus device does not affect the operating be-
