Designation of Lighting Position

The lighting position is designated with a register address in a communication command. The relationship between register address and lighting

position in each matrix configuration is shown in the table below.

Gradation data can be transmitted continuously (continuous transfer). In this case, gradation data are stored sequentially, with the register address

designated at first at the top. Gradation data cannot be transmitted to a register address that is not found in matrix configurations (wrong address).

Communication is terminated if a wrong address is designated, or if a wrong address is reached in continuous transfer of gradation data.

Note: When a 16x8-mode matrix configuration is used, an LED shown in an odd-number row in the table above cannot be designated as the first

address. Gradation data can be transmitted only via continuous transfer to a register address in an odd-number row.
