Calibration Mode (ACDL/MCDL)
ACDL function(Automatic Calibration Function in Dimming light with period)
Method 1.UART Command Set; J1-3pin (UART-RX) and J1-5pin (UART-TX) to Main-Board.
(J2-13pin and J2-14pin are available for B to B connector User as well)
Method 2.I2C Command Set; J1-8pin (SCL) and J1-9pin (SDA) to Main-Board.
Method 3.Execute Hardware based ACDL.
※ 1. To activa te ACDL function, the user’s application must be designed to give Low-Active
Signal toJ1-6pin with High De-Active Signal to J1-10pin continuously.
(J2-6pin and J2-11pin are available for BtoB connector User as well)
Method 4.Let Sensor install on Jig Board TRB-100ST (Test and Recalibration Board) with ambient
air-flow condition and execute by moving jumper with Manual on the website.
Method 5.EK-100TL (Emulation kit, with Emulation program ‘ELTWSD’) is available, which
display and save data on PC through USB connection.
10’ MCDL function(10 minute Manual Calibration Function in Dimming light)
MCDL enable customer to calibrate as needed, MCDL keep at least 10 minute once it start and
