should be stopped before 18minute to avoid MCDL fetch repetition.
Method 1. UART Command Set; pin-3 (UART-RX) and pin-5 (UART-TX) to Main-Board.
(J2-13pin and J2-14pin are available for BtoB connector User as well)
Method 2. I2C Command Set; pin-8 (SCL) and pin-9 (SDA) to Main-Board.
Method 3.Execute Hardware based MCDL.
1. To activate ACDL function, the user’s application must be designed to give Low-Active
Signal topin-10 with High De-Active Signal to pin-6 for 10 minutes. Be careful to make
it sure to quit MCDL fetch loop before 18minute.
(J2-6pin and J2-11pin are available for BtoB connector User as well)
2. Be careful to make it sure to quit MCDL fetch loop before 18minute.
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.
Set present CO2 value with Target PPM function
1. Deviated CO2 sensors can be adjusted with target PPM function via I2C or UART interface.
